The Flaris LAR01 is a Polish five-seat very light jet intended for general aviation use. It is made largely of carbon fiber reinforced polymers and powered by a single turbojet engine – the production version of the LAR01 is to be powered by a single Williams FJ33-5A engine. The LAR01 is intended to be affordable and accessible to individual private owners. Proposed uses for it include air taxi operations, personal transport, emergency medical service and aerial surveillance , as well as its potential modification into an unmanned aerial vehicle (UAV). The LAR01 has been optimized for use by private pilots. Where possible, the cockpit is deliberately designed to mimic that of a traditional car. The designers intend to provide removable. Elliptical wings for the aircraft; this measure is to enable the type to be readily parked within typical garages; sections of the tailplane can be similarly detached for the same purpose. Fuel is housed within a tank mounted on the fuselage, deliberately avoiding the use of the wings for fuel storage. The LAR01 is also reported as being relatively easy to control. Various features for safety and convenience are to be incorporated into the LAR01's design. Unlike many jet-powered aircraft, it is claimed to be readily capable of being operable from unpaved runways and grass strips. For safety purposes, the LAR01 has been designed to use a ballistic rescue parachute system, a parachute being installed within the tail , which is intended to assist in the safe recovery of the aircraft. It can be equipped with various models of Garmin glass cockpit . An electric de-icing system is also fitted. Under 3 mln $ aircraft is forecast to have direct operating costs (fuel, maintenance and insurance) of $450 per hour and have a Garmin G600 TXi flight deck. It should cruise at 430 kn (796 km/h), have a range of 1,900 nm (3,519 km) with a MTOW of 1,500 kg (3,300 lb), and will be able to take off and land on grass airstrips and short runways of less than 250 m (820 ft).

The Fairchild 91 (a.k.a. A-942) was a single-engine eight-passenger flying boat airliner developed in the United States in the mid-1930s. Fairchild designed the aircraft in response to a Pan American Airways request for a small flying boat to operate on their river routes along the Amazon and Yangtze. The result was a conventional high-wing cantilever monoplane with its radial engine mounted above the wing in a streamlined nacelle. Before construction of the prototype was complete, however, Pan American no longer required the aircraft to operate in China, and Fairchild optimised the design for the Brazilian tropics. After the first two aircraft were delivered, Pan American cancelled the remaining four aircraft of its order, as they no longer needed any for China, and the two aircraft were capable of handling the Amazon River. The sole A-942-B was specially built for the American Museum of Natural History and was used by naturalist Richard Archbold on his second expedition to Papua New Guinea in 1936–1937. The prototype was sold to the Spanish Republican Air Force, but the ship carrying it was captured by the Spanish Nationalists and was used by them until 1941. The A-942 bought by industrialist Garfield Wood was sold to the British American Ambulance Corps before being transferred to the RAF, who operated it in Egypt for air-sea rescue. One example was sold to the Imperial Japanese Naval Air Service for evaluation, but it was wrecked shortly after delivery, so a second example was purchased to replace it.

The Australian Lightwing SP-2000 Speed is an Australian light-sport aircraft, designed and produced by Australian Lightwing of Ballina, New South Wales. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft. The aircraft features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear or conventional landing gear and a single engine in tractor configuration. The aircraft fuselage is made from welded steel tubing covered in non-structural fibreglass. Its 8.7 m (28.5 ft) span wing is built from 6061-T6 aluminum covered in doped aircraft fabric and fibreglass. Standard engines available are the 100 hp (75 kW) Rotax 912ULS or the 120 hp (89 kW) Jabiru 3300 four-stroke powerplants. Cockpit access is via gull-winged doors on both sides. Wheel pants are usually fitted. The SP-2000 has been accepted by the US Federal Aviation Administration as a light-sport aircraft as the Outback 2. SP-2000 TD (Tail dragger variant)

The G.46 was a conventional, low-wing monoplane with tailwheel undercarriage, the main units of which retracted inwards. The pilot and instructor sat in tandem under a long canopy. The first prototype, powered by a 205 hp (153 kW) Alfa Romeo 115-Ibis engine, made its maiden flight on 25 June 1947. Testing revealed excellent flying characteristics and suitability for aerobatics, and the type was ordered into production. Apart from the 150 ordered by the Aeronautica Militare, 70 aircraft were exported, to Austria, Argentina and Syria. Variants G.46-1B two-seater with Alfa Romeo 115bis engine, one prototype and initial production of 25 for the Italian Air Force.

Mwari is a new light, multirole aircraft being developed by Paramount Group for armed forces across the globe. It is a military variant of the Advanced High Performance Reconnaissance Light Aircraft (AHRLAC). The Mwari project was unveiled in May 2016. Paramount and Boeing made a cooperation agreement in September 2014 for collaborating on specific projects to be implemented in future. The agreement was extended in May 2016 to jointly develop an advanced mission system for the Mwari aircraft. . The cost-effective Mwari multirole aircraft can be deployed in border patrol, counter insurgency missions, forward air control, forward airdrop and resupply, armed reconnaissance, and electronic intelligence (ELINT) and communication intelligence (COMINT) missions. Other mission capabilities will include internal security, disaster management and maritime patrol. Incorporating a twin-boom design, the Mwari aircraft will feature airframe constructed using meal and composite materials. The longitudinal booms at empennage feature a pair of vertical stabilisers joined by a horizontal stabiliser. The high-wing design will improve visibility for the crew, while allowing operations from unprepared airfields. The modular design will also support the integration of different mission systems for a range of military operations. The aircraft will have a length of 10.5m, wing span of 12m and a height of 4m. The maximum take-off weight of the aircraft is 3,800kg and maximum payload capacity with full fuel load will be more than 800kg.

The CANT 10 was a flying boat airliner produced in Italy in the 1920s. It was a conventional biplane design with single-bay, unstaggered wings of equal span, having seating for four passengers within the hull, while the pilot sat in an open cockpit. The engine was mounted in pusher configuration in the interplane gap. CANT 10 flying boats were used by Società Italiana Servizi Aerei for over a decade, linking destinations in the Adriatic Sea. Two CANT 10ters were used by a company called TAXI AEREI in Buenos Aires, operating flights from the River Plate. One of them was lost in an accident and the other one was bought by the Paraguayan government for the Naval Aviation in 1929; it was used as a transport during the Chaco War and was withdrawn from use in 1933. A total of 18 CANT 10's were built.

Len and Les Alford of Jabiru Aircraft Southern Africa are the South African dealers for Jabiru. They approached Jabiru in 2012 suggesting there was a market for a twin engine Jabiru in Africa. They explained that parts of Africa are best flown over at a great heights, and the prevalence of wild animals and AK47s tends to make flyers nervous about outfield landings. The conclusion…two engines would be nice. The project was always intended to be a joint development and aimed at the South African market. Jabiru had conjured the concept of a twin for some time but could not face up to the complexity generated by hanging the engines off the wings. This would have meant going back to basics on wing structure and all the difficulties of fire-proofing the wings, etc. Another physical difficulty was the engine pods completely obstructed the entry and exit points to the cabin. These considerations gave birth to the idea of mounting the engines on a short canard mounted on the firewall. Some quick calculations on the weight and balance weren’t too frightening and Jabiru was able to get the propellers quite close together to reduce the amount of asymmetric thrust on one engine. The issue of opening the doors against the engine pods was resolved and the design evolved from there. Jabiru’s John Farmer got to work making a streamlined nose for a J430 airplane and the two engine pods. Jabiru’s engineer, Tom Ferguson, was given the task of testing the supporting structure for the engines. As usual, most of the structure was built in composite with aluminum connections to the engines. The firewall structure of the J430 is unchanged and the nose wheel remains in its normal position. This is a relatively simple bolt-on modification. When the structure was finished and the molds were complete, the project was shipped to South Africa where the airplane was completed into a flying prototype. Jabiru is considering releasing the aircraft as a kit for Australian and U.S. builders, and in other countries that accept the experimental category. It’s also possible that it could be released as a conversion to existing experimental J430s in Australia.

The Northrop Gamma was a single-engine all-metal monoplane cargo aircraft used in the 1930s. Towards the end of its service life, it was developed into the A-17 light bomber. The Gamma was a further development of the successful Northrop Alpha and shared its predecessor's aerodynamic innovations with wing fillets and multicellular stressed-skin wing construction. Like late Alphas, the fixed landing gear was covered in distinctive aerodynamic spats, and the aircraft introduced a fully enclosed cockpit. The Gamma saw fairly limited civilian service as mail planes with Trans World Airlines but had an illustrious career as a flying laboratory and record-breaking aircraft. The US military found the design sufficiently interesting to encourage Northrop to develop it into what eventually became the Northrop A-17 light attack aircraft. Military versions of the Gamma saw combat with Chinese and Spanish Republican air forces. Twenty Five Gamma 2Es were assembled in China from components provided by Northrop; these were deployed in various attack missions during the early stages of the Second Sino-Japanese War, particular against Imperial Japanese naval assets. In the morning of 11 November 1937, three Chinese Air Force Northrop 2ECs of the 2nd BG, 14th Squadron led by Capt. Yu attacked the IJN fleet aircraft carrier Kaga off the Ma'anshan Islands; the bombs fell wide into Kaga's wake, and the Chinese Gammas were pursued and intercepted by three A5Ms of Kaga's combat air patrol led by flight leader Jirō Chōno, shooting down two (Gammas no. 1405 of Sung I-Ching and Li Xi-Yong, and no. 1402 of Peng Te-Ming and Li Huan-Chieh) while Yu managed to escape into the clouds and return his damaged Gamma to base. On June 2, 1933 Frank Hawks flew his Gamma 2A "Sky Chief" from Los Angeles to New York in a record 13 hours, 26 minutes, and 15 seconds. In 1935, Howard Hughes improved on this time in his modified Gamma 2G making the west-east transcontinental run in 9 hours, 26 minutes, and 10 seconds. The most famous Gamma was the Polar Star. The aircraft was carried via ship and offloaded onto the pack ice in the Ross Sea during Lincoln Ellsworth's 1934 expedition to Antarctica. The Gamma was almost lost when the ice underneath it broke, and had to be returned to the United States for repairs. Polar Star's second assignment to Antarctica in September 1934 was also futile — a connecting rod broke and the aircraft had to be returned yet again for repairs. On January 3, 1935, Ellsworth and pilot Bernt Balchen finally flew over Antarctica. On November 23, 1935, Ellsworth and Canadian pilot Herbert Hollick-Kenyon attempted the world's first trans-Antarctic flight from Dundee Island in the Weddell Sea to Little America. The crew made four stops during their journey, in the process becoming the first people ever to visit Western Antarctica. During one stop, a blizzard completely packed the fuselage with snow which took a day to clear out. On December 5, after traveling over 2,400 miles (3,865 km) the aircraft ran out of fuel just 25 miles (40 km) short of the goal. The intrepid crew took six days to travel the remainder of the journey and stayed in the abandoned Richard E. Byrd camp until being found by the Discovery II research vessel on January 15, 1936. Polar Star was later recovered and donated to the Smithsonian National Air and Space Museum. For details of the 14 variants, click here. Specifications below are for the Gamma 2D variant.

The Gyroflug SC 01 Speed Canard is an unconventional sports plane produced in Germany in the 1980s and 1990s. Inspired by the Rutan VariEze, the Speed Canard was an all-new design created without input from Rutan. Like the VariEze, the Speed Canard is a canard-configured mid-wing monoplane with wingtip fins that incorporate rudders. The two-seat tandem cockpit and canopy design were derived from Grob Twin Astir sailplane, and the nosewheel of the tricycle undercarriage is retractable. Construction throughout is of composite materials, and when the design attained German certification in 1983, it became the first composite canard design to achieve certification anywhere in the world. An interesting feature of the control system is that the twin rudders operate independently, allowing both rudders to be deflected outwards simultaneously, cancelling each other's yaw, but acting as airbrakes. In 1987, the development of a four-seat version was announced as the E 401, but was abandoned soon thereafter. In late 1988 Gyroflug partnered with Litton Industries using Gyroflug Speed Canard as for Litton's Advanced Tactical Surveillance System.

The Tachikawa Ki-9 (九五式一型練習機, Kyūgo-shiki ichigata renshuki) was an intermediate training aircraft of the Imperial Japanese Army Air Force built by Tachikawa Aircraft Company Ltd in the 1930s. It was known to the Allies under the nickname of "Spruce" during World War II. This aircraft was mistakenly identified as a Tatchikawa by the British. The Ki-9 was a two-seat, unequal wingspan biplane design. Tachikawa originally planned to use the same basic airframe for both basic training and intermediate training, differentiating the two models by the use of different engines. The prototype Ki-9 flew on 7 January 1935, powered by a 261 kW (350 hp) nine-cylinder Hitachi Ha-13a radial engine. The second prototype was identical, and the third prototype was powered by a 112 hp (80 kW) Nakajima NZ seven-cylinder radial engine. The third prototype exhibited stability problems due to a center of gravity issue, and, as a result, the primary trainer model was abandoned and the Ki-9 was developed only for the intermediate trainer. Tachikawa subsequently developed the Ki-17 for the primary trainer role. The first production aircraft were delivered in 1935. The Ki-9 was introduced to service as the Army Type 95-1 Medium Grade Trainer Model A under the former aircraft naming nomenclature system. The first version had a complex, split-axle landing gear with fairings over the top of the wheels. In 1939, this was modified and simplified, the fuselage slightly shortened, and the total weight reduced. The resulting Army Type 95-1 Model B or Ki-9-kai had improved maneuverability and flight characteristics. This version was quickly superseded by the Army Type 95-1 Model C, or Ki-9-otsu, in full production. Both versions were used widely for blind-flying training with a folding hood over the rear cockpit, and several were modified with a glazed canopy over the rear cockpit for use as a staff officer transport plane. Some were pressed into service for use as "special attack" (kamikaze in American terminology) aircraft in the closing days of the war, fitted with either a 100 kg anti-ship bomb, an oil drum filled with explosives, or fuel in the rear cockpit. Production by Tachikawa totaled 2,395 aircraft, ending in 1942. At least another 220 Ki-9s were constructed by Tokyo Gasu Denki (also known as Gasuden) from 1943 to 1945. The Ki-9 was also flown in wartime by Japanese satellite countries and postwar by the fledgling government of Indonesia and captured units by the Republic of China. Variants Ki-9 (Army Type 95-1 Medium Grade Trainer Model A): Initial version two-seat intermediate trainer aircraft. Ki-9-ko (Army Type 95-1 Medium Grade Trainer Model B): Improved version. Ki-9-otsu (Army Type 95-1 Medium Grade Trainer Model C): Standard production version.

The Pilatus PC-8D Twin Porter was a Swiss ten-seat light transport built by Pilatus Aircraft. The type did not go into production and only one was built. Work on the Twin Porter started in 1966, it was a modified Pilatus PC-6 high-wing monoplane with the nose-mounted engine removed and two 290 hp Lycoming IO-540-GIB engines mounted on the wing leading edges.The prototype first flew on 28 November 1967. Only one aircraft was built as flight testing was halted in 1969.

The Lasco Lascondor (also frequently known by the misspelling "Lasconder") was a 1930s Australian 8-seat passenger and mail carrier aircraft built by the Larkin Aircraft Supply Company (Lasco) at Coode Island, Victoria. It is claimed to be the first multi-engined aircraft designed and built in the Southern Hemisphere. Development of the Lascondor began in June 1928, concurrently with the company's Lascoter; the two aircraft had 90% commonality of structural parts. Like the Lascoter the Lascondor was a high-wing monoplane with a tubular steel structure, featuring a tailwheel undercarriage and a fully enclosed cabin for the passengers and the pilot. A major change was the Lascondor's three Armstrong Siddeley Mongoose engines instead of the Lascoter's single more powerful Siddeley Puma engine. The Lascondor also had greater fuel capacity and a slightly longer fuselage with a redesigned cabin to accommodate an extra row of seats. In addition, while the Lascoter had two sets of flying controls in the cockpit the Lascondor had only one to allow for another passenger seat, giving an overall capacity of seven passengers and one pilot. The only available photo of the Lascondor.

The Mitsubishi Ki-46 was a twin-engine reconnaissance aircraft that was used by the Imperial Japanese Army in World War II. Its Army Shiki designation was Type 100 Command Reconnaissance Aircraft (一〇〇式司令部偵察機); the Allied brevity code name was "Dinah". On 12 December 1937, the Imperial Japanese Army Air Force issued a specification to Mitsubishi for a long-range strategic reconnaissance aircraft to replace the Mitsubishi Ki-15. The specification demanded an endurance of six hours and sufficient speed to evade interception by any fighter in existence or development, but otherwise did not constrain the design by a team led by Tomio Kubo and Jojo Hattori. The resulting design was a twin-engined, low-winged monoplane with a retractable tailwheel undercarriage. It had a small diameter oval fuselage which accommodated a crew of two, with the pilot and observer situated in individual cockpits separated by a large fuel tank. Further fuel tanks were situated in the thin wings both inboard and outboard of the engines, giving a total fuel capacity of 1,490 L (328 imperial gallons). The engines, two Mitsubishi Ha-26s, were housed in close fitting cowlings developed by the Aeronautical Research Institute of the Tokyo Imperial University to reduce drag and improve pilot view. The first prototype aircraft, with the designation Ki-46, flew in November 1939 from the Mitsubishi factory at Kakamigahara, Gifu, north of Nagoya.[3] Tests showed that the Ki-46 was underpowered, and slower than required, only reaching 540 km/h (336 mph) rather than the specified 600 km/h (373 mph). Otherwise, the aircraft tests were successful. As the type was still faster than the Army's latest fighter, the Nakajima Ki-43, as well as the Navy's new A6M2, an initial production batch was ordered as the Army Type 100 Command Reconnaissance Plane Model 1 (Ki-41-I). To solve the performance problems, Mitsubishi fitted Ha-102 engines, which were Ha-26s fitted with a two-speed supercharger, while increasing fuel capacity and reducing empty weight. This version, designated Ki-46-II, first flew in March 1941. It met the speed requirements of the original specification, and was ordered into full-scale production, with deliveries starting in July. Although at first the Ki-46 proved almost immune from interception, the Imperial Japanese Army Air Force realised that improved Allied fighters such as the Supermarine Spitfire and P-38 Lightning could challenge this superiority, and in July 1942, it instructed Mitsubishi to produce a further improved version, the Ki-46-III. This had more powerful, fuel-injected Mitsubishi Ha-112 engines, and a redesigned nose, with a fuel tank ahead of the pilot and a new canopy, smoothly faired from the extreme nose of the aircraft, eliminating the "step" of the earlier versions. The single defensive machine gun of the earlier aircraft was omitted not long into the production run. The new version first flew in December 1942, demonstrating significantly higher speed 630 km/h (391 mph) at 6,000 m (19,700 ft). The performance of the Ki-46-III even proved superior to that of the aircraft intended to replace it (the Tachikawa Ki-70), which as a result did not enter production.[8] During operational testing in March 1944, it was discovered that replacing the engines' single exhaust collector ring with individual pipes provided extra thrust and an increase in top speed to 642 km/h (399 mph). In an attempt to yet further improve the altitude performance of the Ki-46, two prototypes were fitted with exhaust driven turbosupercharged Ha-112-II-Ru engines. This version first flew in February 1944, but only two prototypes were built. Mitsubishi factories made a total of 1,742 examples of all versions (34 x Ki-46-I, 1093 x Ki-46-II, 613 x Ki-46-III, 4 x Ki-46-IV) from 1941 to 1944.

The Kyūshū J7W Shinden (震電, "Magnificent Lightning") is a World War II Japanese propeller-driven prototype fighter plane with wings at the rear of the fuselage, a nose-mounted canard, and a pusher engine. Developed by the Imperial Japanese Navy (IJN) as a short-range, land-based interceptor, the J7W was a response to Boeing B-29 Superfortress raids on the Japanese home islands. For interception missions, the J7W was to be armed with four forward-firing 30 mm type 5 cannons in the nose. The Shinden was expected to be a highly maneuverable interceptor, but only two prototypes were finished before the end of the war. A jet engine–powered version was considered, but never reached the drawing board. In the IJN designation system, "J" referred to land-based fighters and "W" to Watanabe Tekkōjo, the company that oversaw the initial design. The idea of a canard-based design originated with Lieutenant Commander Masayoshi Tsuruno, of the technical staff of the IJN in early 1943. Tsuruno believed the design could easily be retrofitted with a turbojet, when suitable engines became available. His ideas were worked out by the First Naval Air Technical Arsenal (Dai-Ichi Kaigun Koku Gijitsusho), which designed three gliders designated Yokosuka MXY6, featuring canards. These were built by Chigasaki Seizo K. K. and one was later fitted with a 22 hp Semi 11 (Ha-90) 4-cylinder air-cooled engine. The feasibility of the canard design was proven by both the powered and unpowered versions of the MXY6 by the end of 1943, and the Navy were so impressed by the flight testing, they instructed the Kyushu Aircraft Company to design a canard interceptor around Tsuruno's concept. Kyushu was chosen because both its design team and production facilities were relatively unburdened, and Tsuruno was chosen to lead a team from Dai-Ichi Kaigun Koku Gijitsusho to aid Kyushu's design works. The construction of the first two prototypes started in earnest by June 1944, stress calculations were finished by January 1945, and the first prototype was completed in April 1945. The 2,130 hp Mitsubishi MK9D (Ha-43) radial engine and its supercharger were installed behind the cockpit and drove a six-bladed propeller via an extension shaft. Engine cooling was to be provided by long, narrow, obliquely mounted intakes on the side of the fuselage. It was this configuration that caused cooling problems while running the engine while it was still on the ground. This, together with the unavailability of some equipment parts postponed the first flight of the Shinden. Even before the first prototype took to the air, the Navy ordered the J7W1 into production, with a quota of 30 Shinden a month given to Kyushu's Zasshonokuma factory and 120 from Nakajima's Handa plant. It was estimated some 1,086 Shinden could be produced between April 1946 and March 1947. On 3 August 1945, the prototype first flew, with Tsuruno at the controls, from Mushiroda Airfield. Two more short flights were made, a total of 45 minutes airborne, one each on the same days as the atomic bombings of Hiroshima and Nagasaki occurred, before the war's end. Flights were successful, but showed a marked torque pull to starboard (due to the powerful engine), some flutter of the propeller blades, and vibration in the extended drive shaft.

The Cessna 190 and 195 Businessliner are a family of light single radial engine powered, conventional landing gear equipped, general aviation aircraft which were manufactured by Cessna between 1947 and 1954. The 195 model was also used by the United States Air Force, United States Army, and Army National Guard as a light transport and utility aircraft under the designations LC-126/U-20. The Cessna 190 and 195 were Cessna's only postwar radial-engined aircraft. The first prototype flew in 1945, after the end of World War II and both the 190 and 195 entered production in 1947. The 195 was the first Cessna airplane to be completely constructed of aluminum and features a cantilever wing, similar to the pre-war Cessna 165 from which it is derived. The wing differs from later Cessna light aircraft in that it has a straight taper from root chord to tip chord and no dihedral. The airfoil employed is a NACA 2412, the same as used on the later Cessna 150, 172 and 182. The 190/195 fuselage is large in comparison to other Cessna models because the 42" diameter radial engine had to be accommodated in the nose. There are two rows of seats: two individual seats in the first row, with a comfortable space between them and up to three passengers can be accommodated on a bench seat in the second row. The 190/195 has flat sprung-steel landing gear legs derived from Cessna's purchase of the rights to Steve Wittman's Big X. Many have been equipped with swiveling crosswind landing gear which allows landing with up to 15 degrees of crab. While the crosswind gear simplifies the actual landing, it makes the aircraft difficult to handle on the ground. The 195 is equipped with a retractable step that extends when the cabin door is opened, although some have been modified to make the step a fixed unit. The aircraft was expensive to purchase and operate for private use and Cessna therefore marketed them mainly as a business aircraft under the name "Businessliner". The engines fitted to the 190 and 195 became well known for their oil consumption. The aircraft has a 5-US-gallon (19 L) oil tank, with 2 US gallons (7.6 L) the minimum for flight. Typical oil consumption with steel cylinder barrels is 2 US quarts (1.9 L) per hour. A factory-produced floatplane version was equipped with a triple tail for improved yaw stability. The Cessna 195 produces a cruise true airspeed of 148 knots (274 km/h) (170 MPH) on a fuel consumption of 16 US gallons (61 L) per hour. It can accommodate five people. Including the LC-126s, a total of 1180 190s and 195s were built. The 190 was originally introduced at a price of USD$12,750 in 1947 (equivalent to $173,978 in 2023). When production ended in 1954 the price had risen to USD$24,700 (equivalent to $280,239 in 2023) for the 195B. This compared to USD$3,495 for the Cessna 140 two seater of the same period. Variants The main difference between the 190 and the 195 models was the engine installed. 190 Powered by a Continental W670-23 engine of 240 hp (180 kW) and first certified on 1 July 1947. 195 (Specifications below) Powered by a Jacobs R-755A2 engine of 300 hp (225 kW) and first certified on 12 June 1947. 195A Powered by a Jacobs L-4MB (R-755-9) engine of 245 hp (184 kW) and first certified on 6 January 1950. 195B Powered by a Jacobs R-755B2 engine of 275 hp (206 kW) and first certified on 31 March 1952. It featured flaps increased in area by 50% over earlier models. LC-126A Military designation for the Cessna 195, five-seat communication aircraft for the US Army, it could be fitted with skis or floats, 15 built. LC-126B Similar aircraft to the LC-126 for Air National Guard use, five built. LC-126C Variant of the LC-126A for instrument training/liaison, 63 built.

The Fairchild C-119 Flying Boxcar (Navy and Marine Corps designation R4Q) is an American military transport aircraft developed from the World War II-era Fairchild C-82 Packet, designed to carry cargo, personnel, litter patients, and mechanized equipment, and to drop cargo and troops by parachute. The first C-119 made its initial flight in November 1947, and by the time production ceased in 1955, 1,183 had been built. The Air Force C-119 and Navy R4Q was initially a redesign of the earlier C-82 Packet, built between 1945 and 1948. The Packet had provided limited service to the Air Force's Tactical Air Command and Military Air Transport Service before its design was found to have several serious problems. Though it continued in service until replaced, all of these were addressed in the C-119, which had its first test flight already in 1947. To improve pilot visibility, enlarge the cargo area, and streamline aerodynamics, the C-119 cockpit was moved forward to fit flush with the nose, rather than over the cargo compartment. The correspondingly longer fuselage resulted in more usable cargo space and larger loads than the C-82 could accommodate. The C-119 also got new engines, with 60% more power, four-bladed props to three, and a wider and stronger airframe. The first C-119 prototype (called the XC-82B) made its initial flight in November 1947, with deliveries of C-119Bs from Fairchild's Hagerstown, Maryland factory beginning in December 1949. In 1951, Henry J. Kaiser was awarded a contract to assemble additional C-119s at the Kaiser-Frazer automotive factory located in the former B-24 plant at Willow Run Airport in Belleville, Michigan. Initially, the Kaiser-built C-119F differed from the Fairchild aircraft by the use of Wright R-3350-85 Duplex Cyclone engines in place of Fairchild's use of the Pratt & Whitney R-4360 Wasp Major radial engine. Kaiser built 71 C-119s at Willow Run in 1952 and 1953 (AF Ser. No. 51-8098 to 51-8168) before converting the factory for a planned production of the Chase C-123 that never eventuated. The Kaiser sub-contract was frowned upon by Fairchild, and efforts were made through political channels to stop Kaiser's production, which may have proven successful. Following Kaiser's termination of C-119 production the contract for the C-123 was instead awarded to Fairchild. Most Kaiser-built aircraft were issued to the U.S. Marine Corps as R4Qs, with several later turned over to the South Vietnamese air force in the 1970s, a few others were later shipped to Belgium and Italy. The AC-119G Shadow gunship variant was fitted with four six-barrel 7.62 mm (0.300 in) NATO miniguns, armor plating, flare launchers, and night-capable infrared equipment. Like the AC-130 that replaced it, the AC-119 proved to be a potent weapon. The AC-119 was made more deadly by the introduction of the AC-119K Stinger version, which featured the addition of two General Electric M61 Vulcan 20 mm (0.79 in) cannon, improved avionics, and two underwing-mounted General Electric J85-GE-17 turbojet engines, adding nearly 6,000 lbf (27 kN) of thrust. Other major variants included the EC-119J, used for satellite tracking, and the YC-119H Skyvan prototype, with larger wings and tail. In civilian use, many C-119s feature the "Jet-Pack" modification, which incorporates a 3,400 lbf (15,000 N) Westinghouse J34 turbojet engine in a nacelle above the fuselage.

The Aerocar Mini-IMP (Independently Made Plane) is a light aircraft designed by Moulton Taylor and marketed for homebuilding by Aerocar International. It is a scaled-down derivative of his original Aerocar IMP design. A two-seat version called the Bullet was also built. The Mini-IMP follows the same unconventional layout as its larger predecessor, with a center mounted engine, long driveshaft to a tail propeller, and inverted-V rudder/elevators. The aircraft is available in the form of plans for amateur construction. Following Taylor's death, the plans and licensing for the Mini-IMP have been marketed by the Mini-IMP Aircraft Company of Weatherford, Texas. The aircraft features a cantilever high-wing, a single-seat enclosed cockpit, fixed or retractable tricycle landing gear or conventional landing gear and a single engine in pusher configuration. The aircraft is made from riveted aluminum sheet. Its 24.5 ft (7.5 m) span wing is mounted well behind the pilot and employs a NASA GA(PC)-1 airfoil. The engine is mounted behind the pilot's seat driving the propeller through an extension shaft. Engines used include the 60 to 100 hp (45 to 75 kW) Volkswagen air-cooled engine four-stroke. Taylor claimed the Mini-IMP was not an original design, but an updated version of the 1912 Edson Fessenden Gallaudet Bullet, a design that was capable of 110 mph in the earliest days of flight. In the late 1970s inquiries were made concerning a military version of the Mini-IMP, skinned with Kevlar, armed with two 7.62-millimeter machine guns, and with room in the baggage compartment for a considerable quantity of ammunition. Nothing came of the proposal.

(No to be confused with the Curtiss SOC Seagull of WW2) The Curtiss Seagull was a civil variant of the Curtiss MF flying boat trainer produced from 1918, the civil aircraft having a 119 kw (160 hp) Curtiss C.6 six-cylinder in-line engine in place of the V-8 unit in the military variants. The MF was one of a long line of flying boats produced for the US services following the entry of the United States into World War I, when flying boats were required for patrolling coastal waters to prevent German submarine operations. Two examples of the Seagull came to Australia. Seagull G-AUCV (c/ n MF.419/28) was registered in 1921. It left Double Bay, Sydney, NSW on 13 March 1921 and made an epic flight to and from Tasmania, this being described as the First Aerial Reconnaissance in Australia, the pilot being Capt Andrew Lang(said to be shot down by the Red Baron during World War I, the operation being financed and promoted by Lebbeus Hordern. Cameras were carried on board in order that aerial photographs could be taken of the coastline. The auxiliary yacht ‘Acielle’ accompanied the expedition and acted as a tender for the Seagull. The flight was made in short stages, the first night being at the Shoalhaven River, near Nowra, NSW, thence to Jervis Bay, Moruya, down the coast to Eden and Marlo where the Victorian Premier, Mr Lawson, was met. Later he was taken for a flight over the area. Stops were made and local flights were made with passengers. From Welshpool it flew to Lady Barren and then across the Tasman, landing on the Tamar River close to Cataract Gorge. The return flight commenced on 19 June and the aircraft arrived at Double Bay on 4 July 1921. The bottom photo below shows the aircraft on the Tamar River.

The Fairey Barracuda was a British carrier-borne torpedo and dive bomber designed by Fairey Aviation. It was the first aircraft of this type operated by the Royal Navy's Fleet Air Arm (FAA) to be fabricated entirely from metal. The Barracuda was developed as a replacement for the Fairey Albacore biplanes. Development was protracted due to the original powerplant intended for the type, the Rolls-Royce Exe, being cancelled. It was replaced by the less powerful Rolls-Royce Merlin engine. On 7 December 1940, the first Fairey prototype conducted its maiden flight. Early testing revealed it to be somewhat underpowered. However, the definitive Barracuda Mk II had a more powerful model of the Merlin engine, while later versions were powered by the larger and even more powerful Rolls-Royce Griffon engine. The type was ordered in bulk to equip the FAA. In addition to Fairey's own production line, Barracudas were also built by Blackburn Aircraft, Boulton Paul, and Westland Aircraft. The type participated in numerous carrier operations during the conflict, being deployed in the Atlantic Ocean, Mediterranean Sea, and the Pacific Ocean against the Germans, Italians, and Japanese respectively during the latter half of the war. One of the Barracuda's most noteworthy engagements was a large-scale attack upon the German battleship Tirpitz on 3 April 1944. In addition to the FAA, the Barracuda was also used by the Royal Air Force, the Royal Canadian Navy, the Dutch Naval Aviation Service and the French Air Force. After its withdrawal from service during the 1950s, no intact examples of the Barracuda were preserved despite its once-large numbers, although the Fleet Air Arm Museum has ambitions to assemble a full reproduction. a total of 2602 Barracudas were built. For details of development and operational history, click here. Variants Barracuda Two prototypes (serial numbers P1767 and P1770) based on the Fairey Type 100 design.

The Blohm & Voss BV 138 Seedrache (Sea Dragon), but nicknamed Der Fliegende Holzschuh ("flying clog", from the side-view shape of its fuselage, as well as a play on the title of the Wagner opera 'Der fliegende Holländer' or 'The Flying Dutchman') was a World War II German trimotor flying boat that served as the Luftwaffe's main seaborne long-range maritime patrol and naval reconnaissance aircraft. A total of 297 BV 138s were built between 1938 and 1943. Originally developed under the company name of Hamburger Flugzeugbau, the type was initially designated the Ha 138. Its appearance was unique in its combination of unusual design features with its twin boom tail unit, short fuselage and trimotor engine configuration. The short hull, with its hydrodynamic step beneath and flat sides, earned it the nickname, "Fliegender Holzschuh" (the flying clog). The booms of the twin tail unit, much like the smaller Focke-Wulf Fw 189 twin-engined reconnaissance monoplane, extended horizontally from the rear of the outer engine nacelles. For hydrodynamic reasons, the hull featured a distinct "turn-down", or "beak" at the stern. The first prototype featured a gull wing, but during the first flight it was discovered that this wing could not generate enough lift, so the concept was abandoned on the second prototype. The airplanes had also a hardpoint for catapult launches from seaplane tenders. Three piston engines were used. The central engine was mounted above the wing, while the wing engines were lower. The pre-production prototypes and the BV 138 A-01 to BV 138 A-06, were powered by various makes of engines ranging from 485 to 746 kW (650–1,000 hp). The first standardized version, BV 138 B-1, was powered by three 880 PS (868 hp, 647 kW) Junkers Jumo 205D two-stroke, opposed-piston aircraft diesel engines. The engine cowlings also had an atypical appearance, due to the unique nature of the vertical orientation of the six-cylinder opposed-piston Jumo 205 diesel engines, and resembled the cowlings of 4 or 6-cylinder inverted inline engines found on smaller civil and utility aircraft from the Jumo 205's propshaft placement, emerging forward at the uppermost front end of the powerplant. The choice for diesel engines made it possible to refuel at sea from U-boats, who also use diesel engines. When refuelling at sea, the airplane had to be fitted with a fuel filter as diesel fuel from ships contains some condensation.

When refuelling at sea, the airplane had to be fitted with a fuel filter as diesel fuel from ships contains some condensation. There were three gun positions on the aircraft: there was one on the bow with an enclosed, powered gun turret with a single MG 151/20 autocannon. On the stern the fields of fire were obstructed by the tail with the horizontal stabilizer, so there was one gun position lower on the fuselage and a second one higher just behind the central top engine. The gun position behind the central engine, which could see over the horizontal stabilizer, was a fully open Scarff ring-like emplacement which could mount a 7.92 mm MG 15 machine gun, but most aircraft mounted a 13 mm MG 131 heavy machine gun. The lower gun position at the rear fuselage sighted below the horizontal stabilizer. It too was left open and equipped with a machine gun on early aircraft, however later most aircraft mounted an enclosed powered turret similar to the one on the bow.

The Bellanca Aircruiser and Airbus were high-wing, single-engine aircraft built by Bellanca Aircraft Corporation of New Castle, Delaware. The aircraft was built as a "workhorse" intended for use as a passenger or cargo aircraft. It was available with wheels, floats or skis. The aircraft was powered by either a Wright Cyclone or Pratt and Whitney Hornet engine. The Airbus and Aircruiser served as both commercial and military transports. The first Bellanca Airbus was built in 1930 as the P-100. An efficient design, it was capable of carrying 12 to 14 passengers depending on the cabin interior configuration, with later versions carrying up to 15. In 1931, test pilot George Haldeman flew the P-100 a distance of 4,400 miles in a time aloft of 35 hours. Although efficient, with a cost per mile figure of eight cents per mile calculated for that flight, the first Airbus did not sell due to its water-cooled engine. The next model, the P-200 Airbus, was powered by a larger, more reliable air-cooled engine. One version (P-200-A) came with floats and operated as a ferry service in New York City, flying between Wall Street and the East River. Other versions included a P-200 Deluxe model, with custom interiors and seating for nine. The P-300 was designed to carry 15 passengers. The final model, the "Aircruiser," was the most efficient aircraft of its day, and would rank high amongst all aircraft designs. With a Wright Cyclone air-cooled supercharged radial engine rated at 715 hp, the Aircruiser could carry a useful load greater than its empty weight. In the mid-1930s, the Aircruiser could carry 4,000 lb payloads at a speed of between 145 and 155 mph, a performance that multi-engine Fokkers and Ford Trimotors could not come close to matching. In 1934, United States federal regulations prohibited single-engine transports on United States airlines, virtually eliminating future markets for the Aircruiser. Where the workhorse capabilities of the Aircruiser stood out was in Canada. Several of "The Flying Ws", as it was commonly dubbed in Canada, were used in northern mining operations, ferrying ore, supplies and the occasional passenger, into the 1970s.

The Sukhoi Su-17 (izdeliye S-32) is a variable-sweep wing fighter-bomber developed for the Soviet military. Its NATO reporting name is "Fitter". Developed from the Sukhoi Su-7, the Su-17 was the first variable-sweep wing aircraft to enter Soviet service and was featured updated avionics. The aircraft also has variants which were designed to be exported to non-Soviet states such as the Sukhoi Su-22 and the less popular Su-20. It was produced from 1967-1990. The Su-17/20/22 series had a long career and has been operated by many air forces, including those of the Russian Federation, former Soviet republics, former Warsaw Pact, countries in the Arab world, Angola, and Peru. The Russian Federation retired its fleet in 1998. Although the Su-17 was capable of carrying nuclear weapons, it was used in roles ranging from close-air support to ground attack. Shortly after the Su-7 fighter-bomber was put into service, the Sukhoi Design Bureau was ordered to develop a modernization program. The program would be aimed primarily at updating on-board avionics and takeoff/landing characteristics. The concept of variable-geometry wings - something gaining wider attention at that time - was adopted. The program was to be led by Sukhoi's head designer, Nikolay Zyrin. In 1963 the Sukhoi OKB with input from TsAGI created a variable-sweep wing technology demonstrator. The S-22I (also known as the Su-7IG, NATO designation "Fitter-B"), converted from a production Su-7BM, had fixed inner portions of the wing with movable outer segments that could be swept to 28°, 45°, or 62°. The S-22I first took off (with Vladimir Ilyushin at the controls) on 2 August 1966. It was later demonstrated at the air parade in Domodedovo in July 1967. Flight testing revealed that the configuration improved both take-off/landing characteristics, range and endurance. Handling was generally better than the fixed wing Su-7, with the exception that buffeting at high angles of attack to warn of imminent stall no longer occurred.

The Doak VZ-4 (or Doak Model 16) was an American prototype Vertical Takeoff and Landing (VTOL) aircraft built in the 1950s for service in the United States Army. Only a single prototype was built, and the U.S. Army withdrew it from active trials in 1963. Edmund R. Doak, Jr., a self-taught engineer and vice president of Douglas Aircraft Company, founded Doak Aircraft Company in Torrance, California, in 1940. The company grew to 4,000 employees during World War II, with subcontracts from every major American aircraft manufacturer. These included molded plywood fuselages for trainers such as the AT-6 and Vultee BT-13, and doors, hatches and gun turrets for a multitude of aircraft. Doak proposed a VTOL aircraft to the U.S. Army's Army Transportation and Research and Engineering Command at Fort Eustis in Newport News, Virginia, in 1950. He touted the aircraft as able to take off and land in a small area, hover and loiter over a target area, and fly backwards like a helicopter without the noise and vibration of a helicopter, while also having the horizontal cruising ability, high speed, wing-mounted weapons, and mission flexibility of a conventional fixed-wing fighter aircraft. Knowing that a Soviet attack on airbases would interdict takeoffs and landings by conventional aircraft, the Army found Doak's proposal attractive, and on 10 April 1956, it awarded Doak a contract to produce a single prototype for use as a research aircraft. The aircraft, designated the Doak Model 16 by the Doak company and assigned the serial number 56-9642, was originally powered by an 840 shp (630 kW) Lycoming YT53 turboprop engine mounted in the fuselage, later replaced by a 1,000 shp (750 kW) Lycoming T53-L-1 turbine. The engine drove two wingtip-mounted fiberglass tilting ducted fan propellers through a "T" box on the engine that transmitted power to the propellers via a 4-inch (102-mm) aluminum tubular shaft and two smaller shafts. Each propeller was 48-inch (1.22-meter) in diameter and the duct outer diameter was 60-inches (1.52-meter)). The fans were positioned vertically for takeoff and landing – with a rotation speed of 4,800 rpm required for liftoff – and rotated to a horizontal orientation for horizontal flight, the first time this VTOL propulsion concept was tested successfully. The aircraft had metal wings and a metal tail. To save weight, the aircraft originally was constructed of uncovered welded steel tubing, but after it was found that the open frame interfered with forward-speed tests, molded fiberglass was installed over its nose section and thin aluminum sheeting over its aft fuselage. It accommodated a two-person crew, with a pilot and observer seated in tandem in the cockpit. The pilot used a standard stick and rudder to control the aircraft. Its landing gear were taken from a Cessna 182 Skylane, its seats from a North American P-51 Mustang, and its duct actuators from a Lockheed T-33 Shooting Star. Flight testing began at Torrance Municipal Airport, and Doak completed several tests by 1958. The Model 16 hovered for the first time on 25 February 1958, and the first transition from vertical to horizontal flight (and back again) took place on 5 May 1958. Although the prototype generally was successful, its short takeoff and landing performance was less than hoped for and it displayed a tendency to nose up while making the transition from vertical to horizontal flight. Doak's engineers believed that they could solve the prototype's problems, and after taxiing testing, 32 hours of flight testing in a test stand, and 18 hours of tethered hovering, the aircraft was transferred to Edwards Air Force Base, California, in October 1958. It underwent another 50 hours of testing, in which it proved capable with the turbine engine of achieving a maximum speed of 230 mph (370 km.hr), a cruise speed of 175 mph (282 km/hr), a range of 250 miles (403 km), an endurance of one hours, and a service ceiling of 12,000 feet (3,658 meters).

The Spirit of St. Louis (formally the Ryan NYP, registration: N-X-211) is the custom-built, single-engine, single-seat, high-wing monoplane that was flown by Charles Lindbergh on May 20–21, 1927, on the first solo nonstop transatlantic flight from Long Island, New York, to Paris, France, for which Lindbergh won the $25,000 Orteig Prize. Lindbergh took off in the Spirit from Roosevelt Airfield, Garden City, New York, and landed 33 hours, 30 minutes later at Aéroport Le Bourget in Paris, France, a distance of approximately 3,600 miles (5,800 km). One of the best-known aircraft in the world, the Spirit was built by Ryan Airlines in San Diego, California, owned and operated at the time by Benjamin Franklin Mahoney, who had purchased it from its founder, T. Claude Ryan, in 1926. The Spirit is on permanent display in the main entryway's Milestones of Flight gallery at the Smithsonian Institution's National Air and Space Museum in Washington, D.C. Officially known as the "Ryan NYP" (for New York to Paris), the single-engine monoplane was designed by Donald A. Hall of Ryan Airlines and named the "Spirit of St. Louis" in honor of Lindbergh's supporters from the St. Louis Raquette Club in his then hometown of St. Louis, Missouri. To save design time, the NYP was loosely based on the company's 1926 Ryan M-2 mailplane, the main difference being the NYP's 4,000-mile (6,400 km) range. As a nonstandard design, the government assigned it the registration number N-X-211 (for "experimental"). Hall documented his design in "Engineering Data on the Spirit of St. Louis", which he prepared for the National Advisory Committee for Aeronautics (NACA) and is included as an appendix to Lindbergh's 1953 Pulitzer Prize winning book The Spirit of St. Louis. B.F. "Frank" Mahoney and Claude Ryan had co-founded the company as an airline in 1925 and Ryan remained with the company after Mahoney bought out his interest in 1926, although there is some dispute as to how involved Ryan may have been in its management after selling his share. It is known, however, that Hawley Bowlus was the factory manager who oversaw construction of the Ryan NYP, and that Mahoney was the sole owner at the time of Donald A. Hall's hiring. The Spirit was designed and built in San Diego to compete for the $25,000 Orteig Prize for the first nonstop flight between New York and Paris. Hall and Ryan Airlines staff worked closely with Lindbergh to design and build the Spirit in just 60 days. Although what was actually paid to Ryan Airlines for the project is not clear, Mahoney agreed to build the plane for $6,000 and said that there would be no profit; he offered an engine, instruments, etc. at cost. After first approaching several major aircraft manufacturers without success, in early February 1927 Lindbergh, who as a U.S. Air Mail pilot was familiar with the good record of the M-1 with Pacific Air Transport, wired, "Can you construct Whirlwind engine plane capable flying nonstop between New York and Paris ...?" Mahoney was away from the factory, but Ryan answered, "Can build plane similar M-1 but larger wings... delivery about three months." Lindbergh wired back that due to competition, delivery in less than three months was essential. Many years later, John Vanderlinde, chief mechanic of Ryan Airlines, recalled, "But nothing fazed B.F. Mahoney, the young sportsman who had just bought Ryan." Mahoney telegraphed Lindbergh back the same day: "Can complete in two months." Lindbergh was convinced: "I believe in Hall's ability; I like Mahoney's enthusiasm. I have confidence in the character of the workmen I've met."[citation needed] He then went to the airfield to familiarize himself with a Ryan aircraft, either an M-1 or an M-2, then telegraphed his St. Louis backers and recommended the deal, which was quickly approved. Mahoney lived up to his commitment. Working exclusively on the aircraft and closely with Lindbergh, the staff completed the Spirit of St. Louis 60 days after Lindbergh arrived in San Diego. Powered by a Wright Whirlwind J-5C 223-hp radial engine, it had a 14 m (46-foot) wingspan, 3 m (10 ft) longer than the M-1, to accommodate the heavy load of 1,610 L (425 gal) of fuel. In his 1927 book We, Lindbergh acknowledged the builders' achievement with a photograph captioned "The Men Who Made the Plane", identifying: "B. Franklin Mahoney, president, Ryan Airlines", Bowlus, Hall and Edwards standing with the aviator in front of the completed aircraft. Lindbergh believed that multiple engines resulted in a greater risk of failure while a single-engine design would give him greater range. To increase fuel efficiency, the Spirit of St. Louis was also one of the most advanced and aerodynamically streamlined designs of its era. Lindbergh believed that a flight made in a single-seat monoplane designed around the dependable Wright J-5 Whirlwind radial engine provided the best chance of success. The Ryan NYP had a total fuel capacity of 450 U.S. gallons (1,700 L; 370 imp gal) or 2,710 pounds (1,230 kg) of gasoline, which was necessary in order to have the range to make the anticipated flight non-stop. The fuel was stored in five fuel tanks, a forward tank – 88 U.S. gal (330 L; 73 imp gal), the main – 209 U.S. gal (790 L; 174 imp gal), and three wing tanks – total of 153 U.S. gal (580 L; 127 imp gal).[5] Lindbergh modified the design of the plane's "trombone struts" attached to the landing gear to provide a wider wheelbase in order to accommodate the weight of the fuel. At Lindbergh's request, the large main and forward fuel tanks were placed in the forward section of the fuselage, in front of the pilot, with the oil tank acting as a firewall. This arrangement improved the center of gravity and reduced the risk of the pilot being crushed to death between the main tank and the engine in the event of a crash. This design decision meant that there could be no front windshield, and that forward visibility would be limited to the side windows. This did not concern Lindbergh as he was accustomed to flying in the rear cockpit of mail planes with mail bags in the front. When he wanted to see forward, he would slightly yaw the aircraft and look out the side. To provide some forward vision as a precaution against hitting ship masts, trees, or structures while flying at low altitude, a Ryan employee who had served in the submarine service installed a periscope which Lindbergh helped design. It is unclear whether the periscope was used during the flight. The instrument panel housed fuel pressure, oil pressure and temperature gauges, a clock, altimeter, tachometer, airspeed indicator, bank and turn indicator, and a liquid magnetic compass. The main compass was mounted behind Lindbergh in the cockpit, and he read it using the mirror from a women's makeup case which was mounted to the ceiling using chewing gum. Lindbergh also installed a newly developed Earth Inductor Compass made by the Pioneer Instrument Company which allowed him to more accurately navigate while taking account of the magnetic declination of the earth. Lindbergh's ultimate arrival in Ireland deviated from his flight plan by just a few miles. Lindbergh sat in a cramped cockpit which was 94 cm wide, 81 cm long and 130 cm high (36 in × 32 in × 51 in). The cockpit was so small, Lindbergh could not stretch his legs. The Spirit of St. Louis was powered by a 223 hp (166 kW), air-cooled, nine-cylinder Wright J-5C Whirlwind radial engine. The engine was rated for a maximum operating time of 9,000 hours (more than one year if operated continuously) and had a special mechanism that could keep it clean for the entire New York-to-Paris flight. It was also, for its day, very fuel-efficient, enabling longer flights carrying less fuel weight for given distances. Another key feature of the Whirlwind radial engine was that it was rated to self-lubricate the engine's valves for 40 hours continuously. Lubricating, or "greasing," the moving external engine parts was a necessity most aeronautical engines of the day required, to be done manually by the pilot or ground crew prior to every flight and would have been otherwise required somehow to be done during the long flight. The engine was built at Wright Aeronautical in Paterson, New Jersey by a 24-year-old engine builder, Tom Rutledge, who was disappointed that he was assigned to the unknown aviator, Lindbergh. Four days after the flight, he received a letter of congratulations from the Wright management. For more information, click here.

The most anticipated version of the phenomenally successful Sling series is the Sling High Wing. The High Wing – or just Sling HW – was first proposed as a high wing version of the Sling 2 at the same time as founder Mike Blyth started work on the original Sling 2 back in 2005. The final product has come a long way from the early Sling 2s. The Sling TSi is unique in that it is the only aircraft that comes in almost identical low wing and high wing versions. For this reason the comparison with the low wing Sling TSI is particularly interesting. The rationale for developing both a low wing and a high wing are many. Mike Blyth provides the following reasons: “The engine–airframe combination of the Sling TSi is so perfect that to fail to exploit it in a high wing model would feel like a crime. Also, there’s a real gap in the market as there is no other aircraft in that space. And you can see really well out of a high wing when flying straight, and it can be a great camera and/ or surveillance platform.” The Sling HW made its first flight as promised before the end of 2020. That development and construction had continued through the Covid lockdown is testimony to the dedication and commitment the Sling team brought to the project. A readily noticeable difference between the Low Wing and High is that the high has a vertical fin and rudder a full 20 cm longer than the Low Wing. Given the High Wing ‘nosedraggers’ high stance, this may make getting the tail under a low hangar door opening something to watch. The Sling HW and TSi are immediately distinguishable by the large NACA duct on the right side of the cowl which feeds air into the engine’s high-volume intercooler. Sling Aircraft has done a great job integrating this duct into the Sling’s distinctive shark nose cowling. For the full write-up from which these notes were extracted click here.

Archon SF-1 is an evolutionary unique aircraft, that utilizes the look of a modern fighter aircraft but lies into the Ultalight(EU)/LSA(USA) category. The idea behind the design is an affordable recreational aircraft that offers the impression and the feeling of a fighter aircraft. It was designed and built in Greece, by George Iliopoulos. The maiden flight was made in July, 2009. Since then, it’s been being test flown in regular basis and have received minor changes to improve the overall flight qualities. The standard engine mount is for the Rotax 503, 532, 582 engines.Alluminum alloy construction, light-weight and durable material, corrosion resistant, UV protected. Easy to work with.Basic skills and tools required to assemble in a small workshop.

The Junkers G.38 was a large German four-engined transport aircraft which first flew in 1929. Two examples were constructed in Germany. Both aircraft flew as a commercial transport within Europe in the years leading up to World War II. During the 1930s, the design was licensed to Mitsubishi, which constructed and flew a total of six aircraft, in a military bomber/transport configuration, designated Ki-20. The G.38 carried a crew of seven. Onboard mechanics were able to service the engines in flight due to the G.38's blended wing design, which provided access to all four power plants. During the 1920s, Hugo Junkers made several attempts to produce a large scale commercial transport. His initial attempt, the four-engined JG1, was developed during 1921-1922; but Junkers was forced to destroy the incomplete airplane based on post-WWI Allied demands citing the Treaty of Versailles. Later in the decade, in 1925, he published design specifications for a proposed eighty passenger trans-Atlantic aircraft - the J.1000 project. Then again, towards the end of the decade, the G.40 project was started by the Junkers design team as a trans-Atlantic mail plane. From the G.40 design, which was a seaplane configuration, Junkers also developed a landplane design, designated the G.38. Despite interest from the German armed forces in the G.40 variant, Junkers pushed forward with the landplane design which, having received financing from the Reich Air Ministry (Reichsluftfahrtministerium), was taken forward to the construction stage. The first Junkers prototype—3301 and marked as D-2000—first flew on 6 November 1929 with four diesel engines: two Junkers L55 V-12 engines and two 294 kW L8 inline-6 engines, with a total power rating of 1470 kW (1971 hp). The Reich Air Ministry purchased the D-2000 for demonstration flights, and took delivery on 27 March 1930. In flight tests, the G.38 set four world records including speed, distance and duration for airplanes lifting a 5000 kg payload. On 2 May 1930 Luft Hansa put the D-2000 into commercial service for both scheduled and chartered flights. Structurally the G.38 conformed to standard Junkers' practice, with a multi-tubular spar cantilever wing covered (like the rest of the aircraft) in stressed, corrugated duraluminium. The biplane tail, found in other large aircraft of the time, was intended to reduce rudder forces; initially there were three rudders with only a central fixed fin. The undercarriage was fixed, with double tandem main wheels that were initially enclosed in very large spats. The wing had the usual Junkers "double wing" form, the name referring to the full span movable flaps which served also as ailerons in the outer part. On 2 February 1931 the Leipzig-based Junkers' yard re-engined the D-2000 with two Junkers L8 and two L88 engines, giving a total power rating of 1764 kW (2366 hp) and increasing passenger capacity from 13 to 19. During its early life the G.38 was the largest landplane in the world. Passenger accommodation was sumptuous by today's standards and was meant to rival that found on the competing Zeppelin service offered by DELAG. The plane was unique in that passengers were seated in the wings, which were 1.7 m (5 ft 7 in) thick at the root. There were also two seats in the extreme nose. The leading edge of each wing was fitted with sloping windscreens giving these passengers the forward-facing view usually available only to pilots. There were three 11-seat cabins, plus smoking cabins and washrooms. In design terms the G-38 followed the Blended Wing Body design pioneered by Louis de Monge, later followed by Vincent Burnelli in his UB14 and later CBY-3 designs, and even later considered by both NASA and Boeing as an alternative to traditional tube and wing aircraft configurations.

The Silence Twister is a German ultralight designed by Silence Aircraft for amateur construction, either from plans or kits. The prototype first flew on 30 September 2000. The Twister is a single-seat low-wing monoplane with elliptical wings and tailplane. It has a retractable conventional landing gear with a fixed tailwheel. The design drew inspiration from the Supermarine Spitfire, and the shapes of the Twister's wings, fin and tailplane all recall the famous World War II fighter. Designed to take engines up to 94 hp (70 kW), the prototype was fitted with a 53.6 hp (40 kW) single-rotor MidWest Wankel engine. This compact rotary motor allowed a sleek engine cowling, but the engine was rejected and production aircraft use 85 hp (63 kW) Jabiru 2200 or 95 hp (71 kW) ULPower UL260i engines. An electric aircraft version was under development in 2010. The Twister prototype was fitted with Silence Aircraft's own automatic variable-pitch propeller called the "VProp". The LAA have yet to allow the VProp to be fitted on UK aircraft, so UK Twisters have fixed-blade propellers instead. Twenty-one examples had been completed and flown by December 2011. Variants SA155 Initial prototype powered by a 34 kW (45 hp) MidWest AE50 Wankel rotary engine. The second prototype was powered by a 34 kW (45 hp) Diamond AE50 engine.[2] SA180 powered by a 60 kW (80 hp) Jabiru 2200 engine.[2] Akron A version developed for the US market under Experimental aircraft certification rules.

Following the success of the de Havilland DH.50J in Australia, the company was asked to design a larger replacement using a Bristol Jupiter engine. The cabin had room for six to eight passengers with the pilot in an open cockpit behind the wings. The aircraft took only 10 weeks to design and the prototype first flew in December 1927. Following test flights in England, the aircraft was sent to de Havilland Australia in Melbourne. After reassembly, the prototype first flew on 2 March 1928 and was used on scheduled services between Adelaide and Broken Hill by MacRobertson Miller Aviation. The prototype was originally called Canberra which was used as a type name until it was changed to Giant Moth. A total of 10 aircraft were built, including one in Canada built from components with the rest coming from the Stag Lane production line. Three aircraft for Canada (G-CAPG), (G-CARD) and (G-CAJT) were fitted with Short Brothers floats at Rochester before one was delivered to Canadian Vickers. Three aircraft were used in Australia on air mail services by Australian Aerial Services Ltd and QANTAS. The two QANTAS Giant Moths, Apollo (G-AUJB) and Diana (G-AUJC), were acquired in April and May 1929 respectively. They were the first QANTAS aircraft equipped with toilets. The airline took them out of service in 1935 because the Bristol Jupiter XI engines were unreliable. Apollo was sold that year and crashed near Mubo, New Guinea, on 9 May 1938. Another aircraft, Geraldine (G-AAAN), was bought by the Daily Mail to carry a photographer and his motorcycle around the United Kingdom. For more information, click here.

Powered by four turboprop engines each driving a pair of contra-rotating propellers, the design was the first wide-body transport aircraft and remains the world's largest turboprop-powered aircraft to date. The An-22 first appeared publicly outside the Soviet Union at the 1965 Paris Air Show. Thereafter, the model saw extensive use in major military and humanitarian airlifts for the Soviet Union, and is still in service with the Russian Air Force. In the late 1950s, the Soviet Union required a large military transport aircraft to supplement the Antonov An-8 and An-12s then entering service. Originally known as the An-20, the model is a conventional multi-engined high-wing design. In the early 1960s, the Antonov bureau produced a wooden mock up at its Kyiv, Ukraine, workshops of what was designated the Model 100. The prototype, now designated the An-22, was rolled out on 18 August 1964 and first flew on 27 February 1965. The prototype was given the name Antaeus (sometimes misspelled Antheus) and, after four-months of test flying, was displayed at the 1965 Paris Air Show. All aircraft were built at the Tashkent State Aircraft Factory and the first military delivery was made to the Air Transport Wing at Ivanovo Airbase in 1969. The aircraft was designed as a strategic airlifter, designed specifically to expand the Soviet Airborne Troops' capability to land with their then-new BMD-1 armoured vehicles. The An-22 cargo hold can accommodate four BMD-1s compared to only one in the An-12. It has the capability to takeoff from austere, unpaved, and short airstrips, allowing airborne troops to perform air-landing operations. This is achieved by four pairs of contra-rotating propellers, similar to those on the Tupolev Tu-114. The propellers and exhaust from the engines produce a slipstream over the wings and large double-slotted flaps. The landing gear is ruggedized for rough airstrips. In early versions tire pressures could be adjusted in flight for optimum landing performance. That feature was removed in later models. A total of 69 units were built.

Intended for autonomous operation in the unmarked areas of Russia's far north and Siberia, the Be-103 was designed for short-haul routes in regions that have rivers, lakes and streams, but are otherwise inaccessible. The Be-103 is a mid-wing monoplane, making use of the modified wing roots as water-displacing sponsons. It features an all-moving slab tail and retractable tricycle landing gear for land operations. Its hallmark and most distinguishing design feature is the water-displacing wing, an unusual feature for a seaplane, with three aquaplaning implements (planing step, port and starboard wing trailing edges) which substantially enhance the aircraft's on-the-water stability and seaworthiness. The Be-103 features include an advanced, blended wing, swept at 22°, with 11-foot (3.4 m)-long fixed leading edge slats, trailing-link main landing gear, and three-bladed MT-12 reverse pitch propellers. Fuel is stored in the wet wings. The aircraft is built from aluminum-lithium alloy with titanium used in high-stress areas. A 30-parameter, five-hour flight data recorder, engine fire-detection systems and an ice detector are also standard, as are hydraulic brakes. However, unlike most modern aircraft, the Be-103 is not equipped with wing flaps. When flying solo, ballast must be placed near the right front seat due to center of gravity issues. As of 2010, three aircraft were on the United States civil register. In 2004 China signed a US$20mil contract with KnAAPO for the delivery of 20 aircraft. In 2016 contract was signed between Taganrog-based Beriev Aircraft Company and the Chinese Energy Leader Aircraft Manufacturing to start licensed production of Beriev Be-103 in China. Variants Be-103 Twin-engine light utility amphibian aircraft, seating one pilot and five passengers. SA-20P Eight-seat version powered by single VOKEM M14X radial engine; one prototype.

They held the distinction of being the largest airliners in regular use in the world upon the type's introduction in 1931. The H.P.42/45 were designed in response to a specification issued during 1928 by British airline Imperial Airways; the two models share considerable similarities, the H.P.42 being optimised towards greater range at the expense of payload while the H.P.45 had these priorities inverted, allowing the latter to carry more passengers over shorter distances. Imperial Airways approved of Handley Page's proposals and ordered four aircraft of the two variants to serve as the new land-based long-distance flagships of its fleet. On 14 November 1930, the prototype, named Hannibal, conducted its maiden flight. Following their introduction into Imperial Airways, they formed the backbone of the airliner's land-based fleet through most of the 1930s and, along with the company's numerous flying boats, have been considered to be icons of their era. A total of eight aircraft were built, four of each type; all were named, with names beginning with the letter "H". Three of the survivors were pressed into Royal Air Force (RAF) service at the outbreak of the Second World War. By the end of 1940, all of the aircraft had been destroyed as a result of several accidents. In total, four H.P.42 and four H.P.45 aircraft were delivered, but two of the HP45s were later converted into HP42s. The H.P.45 carried more passengers with a reduced range and baggage capacity, and was intended for Imperial Airways' European routes. For details of the development, design, operational history and individual histories of each of the eight aircraft, click here. The specifications below are for the H.P.42 variant.

It is a conventional low-wing monoplane featuring all-metal construction and tricycle undercarriage. Jilhavan Aircraft built the Kappa Sova for Kappa 77 from 1997 to 2004 and obtained marketing rights in 2005 when Kappa became insolvent. They became a subsidiary of Skyleader Aircraft in 2008 when the type was redesignated Jihlavan Skyleader. It is an all-metal design apart from a carbon fibre cockpit frame. It has two-spar tapered wings with 6° of dihedral, electrically operated Fowler flaps and upturned Küchemann tips. The fin and rudder are swept. The straight tapered tailplane is set on top of the fuselage, the port elevator carrying a trim tab. The original Sova/Skyleader 150 has staggered side-by-side configuration seating with the starboard seat 200 mm (8 in) aft of the other, but a widened fuselage allows the Skyleader 200 to have true side-by-side seating. The earlier version has a forward-hinged canopy with fixed rear transparencies; the Skyleader 200 has a single-piece canopy. Both these variants normally have an electrically actuated tricycle undercarriage with a steerable nosewheel, though a fixed version is an option and is standard on the later Skyleader 500 and 600 variants.

The ANF Les Mureaux 110 and its derivatives were a family of all-metal military reconnaissance aircraft developed and produced by the French aircraft manufacturer ANF Les Mureaux. It was designed in response to a requirement issued by the French air ministry. Introduced to service during the 1930s, in excess of two hundred aircraft were procured for the French Air Force to equip not just its frontline units but also to replace aircraft such as the Potez 25s from reserve units. Multiple variants were operated by the service, perhaps most noteworthy was the conversion of 40 aircraft to serve as dedicated night fighters. The family was in widespread usage at the start of the Second World War, and thus saw intense combat during the Battle of France. All remaining aircraft were scrapped in the aftermath of the armistice with Germany. The ANF Les Mureaux 110 originated with a French air ministry requirement for an aircraft to replace the Breguet 19 in Armée de l'Air service in the "R2" two-seat reconnaissance role. ANF Les Mureaux opted to produce a clean-sheet response to this requirement. It was during this design work that the firm developed a new technique for metal construction, it was promptly incorporated into the new long distance observation aircraft, which was later designated 111. Two slightly different variants, the 110 and 111 were presented to the air force for evaluation, and were ordered into production soon thereafter. The first mass-production version was the 113 in 1933, of which 49 examples were purchased. This was supplanted in production by the 115 in 1935 and the 117 later than year. Both these series were given light bombing capability as well. For details of design, operational history and 10 variants, click here.

The Pietenpol Air Camper is a simple parasol wing homebuilt aircraft designed by Bernard H. Pietenpol. The first prototype that became the Air Camper was built and flown by Pietenpol in 1928. The Air Camper was designed to be built of spruce and plywood. One of Pietenpol's goals was to create a plane that was affordable and easy to construct for home builders. Building an Air Camper requires basic woodworking skills and tools. Builders also need to fabricate some metal fittings to attach the wooden parts. Some welding is required. The plans for the Pietenpol Aircamper were originally published in a four-part serial in the "Flying and Glider" Manual of 1932-33. The original model was flown using an Ace four cylinder water-cooled engine. The Model A Ford engine later became the standard powerplant used; the design was first flown with one in May 1929. In the 1960s Bernard Pietenpol began to favor converted engines from Chevrolet Corvair automobiles. The Corvair flat six was higher horsepower, smoother, and significantly lighter, compared to the Model A, and was similar to those already available for general aviation use. The length of a Pietenpol varies with the engine choices, as lighter engines needed to be mounted further forward for weight and balance reasons. Over the years over 30 different engines have flown in the Pietenpol Air Camper. Many modern Pietenpol builders prefer Continental A65, C85 or C90 air-cooled flat fours. Several examples of the Aircamper have been built in Europe and in 2012 were still flying. In the 1920s and 1930s, kits were available for the design, but there were none available again until 2015 when the Pietenpol Aircraft Company introduced a kit version of the Air Camper, with components supplied by Aircraft Spruce & Specialty. The kit includes all parts except the engine, dope, fabric covering, and hardware. For details of variants, click here.

The Messerschmitt Me 410 Hornisse (Hornet) is a heavy fighter and Schnellbomber ("Fast Bomber" in English) designed and produced by the German aircraft manufacturer Messerschmitt. It was flown by the Luftwaffe during the latter half of the Second World War. Work began on producing a successor to the Bf 110 in 1937, however, the resulting Me 210 proved to be unsatisfactory, leading to production being halted in April 1942. Various options were considered, including the ambitious Me 310 derivative. Officials favoured an incremental improvement which was represented by the Me 410. Although visually similar to the preceding Me 210, and was sharing sufficient design similarities that incomplete Me 210s could be converted into Me 410s, there were key differences between the two aircraft. Chiefly, the Me 410 was powered by larger Daimler-Benz DB 603 engines, had a lengthened fuselage, and automatic leading edge slats. During late 1942, the Reichsluftfahrtministerium (RLM) were sufficiently convinced by the programme to proceed with quantity production of the type, the first Me 410s being delivered during January 1943. Various models were produced, including the Me 410A-1 light bomber, the A-1/U1 aerial reconnaissance aircraft, the A-1/U2 bomber destroyer, and the A-2/U4 night fighter. Upon their entry to service, the type was promptly flown on night time bombing missions in the British Isles, where the night fighters of the Royal Air Force (RAF) typically struggled to intercept it.[2] The Me 410 was also used as a bomber destroyer against the daylight bomber formations of the United States Army Air Forces (USAAF); it was moderately successful against unescorted bombers through 1943, but proved to be no match in a dogfight with the lighter Allied single-engine fighters, such as the North American P-51 Mustang and Supermarine Spitfire. Following the Normandy landings, Me 410s were amongst the numerous Axis aircraft sent against the incoming Allied forces. From mid-1944, all Me 410s were withdrawn from Defence of the Reich duties and production was phased out in favour of heavily armed single-engine fighters as dedicated bomber destroyers. The final role of the Me 410 was aerial reconnaissance. Only two Me 410s have survived in preservation into the twenty-first century. Number built 1,189; First flight 14 March 1942; Retired 1945 Fpr details of development, design, operational history and variants, click here.

The Vickers Warwick was a British twin-engined bomber aircraft developed and operated during the Second World War that was primarily used in other roles. In line with the naming convention followed by other RAF heavy bombers of the era, it was named after a British city or town, in this case Warwick. The Warwick was the largest British twin-engined aircraft to see use during the Second World War. The Warwick was designed and manufactured by Vickers-Armstrongs during the late 1930s. It was intended to serve as a larger counterpart to the Vickers Wellington bomber. The two aircraft share similar construction and design principles but development of the Warwick was delayed by a lack of suitable engines. Its first flight was on 13 August 1939 but delays to its intended powerplant and by the time adequate engines were available, it was obsolete. The Warwick entered production during 1942 and squadron service with the Royal Air Force (RAF). Barely a dozen aircraft were built as bombers. The type was used by RAF Transport Command as a transport, and by RAF Coastal Command as an air-sea rescue and maritime reconnaissance aircraft. The Warwick was also operated by the Polish Air Forces in exile in Great Britain and the South African Air Force. A civil operator, the British Overseas Airways Corporation (BOAC), also operated a handful of transport Warwicks. In October 1932, the British industrial conglomerate Vickers-Armstrongs tendered for the Air Ministry Specification B.9/32, which called for the development of a twin-engined medium bomber. During late 1934, when the company was already developing their Type 271 to meet Specification B.9/32, Vickers received a draft requirement for a larger bomber. The draft specification developed into Air Ministry Specification B.1/35, which sought a twin-engined heavy strategic bomber. It was intended to make use of more powerful engines, of 1,000 hp (750 kW), that were being developed, to enable the bomber to be faster and carry a heavier bomb load than the earlier B.3/34. Among the requirements of Specification B.1/35 was a speed of no less than 195 mph (314 km/h) while flying at 15,000 ft (4,600 m), a range of 1,500 mi (2,400 km) while carrying 2,000 lb (910 kg) of bombs, and the engines were to be furnished with variable-pitch propellers. It was designed in parallel with the smaller Wellington, both aircraft having been derived from the Vickers Type 271 design, developed for Specification B.9/32. By the end of July 1935, the Air Ministry was considering eight designs. These included Vicker's proposal, the Type 284, powered by a pair of Bristol Hercules engines, which exceeded the specifications. Vickers received an order for a prototype on 7 October 1935, while the Air Ministry also ordered prototypes from Armstrong Whitworth (the AW.39, a development of the Armstrong Whitworth Whitley) and Handley Page (the HP.55). These alternative designs were cancelled before being built, as Handley Page and Armstrong Whitworth switched to work on newer specifications released for medium (P.13/36) and heavy (B.12/36) bombers. For more details of development and design, operational history and 12 variants, click here. Total number built was 846.

The Bloch MB.120 was a French three-engine colonial transport aircraft built by Société des Avions Marcel Bloch during the 1930s. The MB.120 design was selected by the French government for transport use in French overseas territories. It was an all-metal high-wing cantilever monoplane. The prototype was re-worked from the MB.71. Standard accommodation was for a crew of three and up to 10 passengers. The civil aircraft normally carried only four passengers, the rest of the aircraft was filled with mail. Ten production aircraft were produced, six for civil use and four for the French Air Force. The aircraft entered operation in 1934 for Air Afrique, which was a new airline set up by the French government on 11 May 1934 to provide service between the French African territories. Both the civil and military aircraft served only in French Africa. Variants MB.120.01 : First prototype. MB.120 : Three-engined colonial transport aircraft. Ten built.

The Helio Twin Courier is a twin-engined version of the Helio Courier, with only seven examples being produced. Known by Helio as the model H-500 this STOL aircraft mounted twin Lycoming engines on top of the high-set wing, close to the fuselage. With the engines mounted in this manner, lateral and over-the-nose visibility were much improved while the propellers were kept clear of cabin doors and away from possible debris damage during rough field operations. This was a tail-wheel design, so the vertical component of propeller thrust assisted STOL take-off performance from rough fields. In 1967 or 68, work was started on a redesign of the Twin Courier in a tricycle-gear configuration for the commercial market, since many firms which desired STOL capability had regulations which required multi-engine aircraft. The company ran out of money and the project was terminated. The aircraft structure of the Helio Stallion, a single-engine turboprop version of the more successful Helio Courier, was based on the design of the Twin Courier. The Twin Courier could seat six and first flew in April 1960, being awarded FAA certification on June 11, 1963. (The Twin Courier met FAA requirements marginally and was certificated to meet immediate needs for service in Vietnam, on the understanding that the design would not be marketed commercially. Thus, the redesign mentioned above.) Only seven examples were built, these receiving the United States Armed Forces designation U-5A. One was reported to have been evaluated by US Army Special Forces. Furthermore, fully automatic full-span, leading-edge slats were fitted along with high-lift flaps.

The Junkers Ju 60 was a single engine airliner built in prototype form in Germany in the early 1930s. It was designed to meet a requirement issued by the Reichsverkehrsministerium (Reich Transport Ministry) for a German-built equivalent to the Lockheed Vega with which to equip Deutsche Luft Hansa. The result was a sleek, cantilever monoplane of conventional configuration, with wings skinned in the corrugated duralumin that had been a hallmark of Junkers designs up to this time, although this would be the last Junkers aircraft to have this feature. The main units of the tailwheel undercarriage were retractable. The Ju 60 was evaluated by Deutsche Luft Hansa against the Heinkel He 70. With the latter able to demonstrate a top speed 75 km/h (47 mph) better than the Ju 60, development of the Junkers design was halted before the third prototype had been completed. The two examples that had already been constructed eventually saw service with the Luftwaffe as liaison aircraft until 1942. The work done on the design would later form the basis of the Ju 160.

The North American AJ Savage (later A-2 Savage) is an American carrier-based medium bomber built for the United States Navy by North American Aviation. The aircraft was designed shortly after World War II to carry atomic bombs and this meant that the bomber was the heaviest aircraft thus far designed to operate from an aircraft carrier. It was powered by two piston engines and a turbojet buried in the rear fuselage. The AJ-1 first became operational in 1950 and several were based in South Korea during 1953 as a deterrent against North Korea. Of the 140 built, plus three prototypes, 30 were reconnaissance aircraft. Inflight-refueling equipment was deployed on the Savage in the mid-1950s. The bomber was replaced by the Douglas A3D Skywarrior beginning in 1957. The type was used after its military service for some additional experiments including microgravity test flights and to test a new jet engine in the 1960s and 70s. At the end of World War II, the U.S. Navy began a design competition on 13 August 1945 for a carrier-based bomber which could carry a 10,000-pound (4,536 kg) bomb that was won by North American Aviation. Later that year, the Navy decided that it needed to be able to deliver atomic bombs and that the AJ Savage design would be adapted to accommodate the latest Mark 4 nuclear bomb, the next step in development from the more sophisticated imploding-plutonium-sphere design Fat Man Mk3 used on Nagasaki. A contract for three XAJ-1 prototypes and a static test airframe was awarded on 24 June 1946. The first prototype made its maiden flight two years later on 3 July 1948. That same year the US Navy began an interim capability program employing the Lockheed P-2 Neptune carrying a crash-program reproduction of the smaller, simpler all-uranium 'gun' design Little Boy nuclear bomb as its first carrier-launched nuclear bomber aircraft until the Savage was in service. The Neptune launched using JATO assist but could not land on existing carriers; if launched they had to either ditch at sea after the mission or land at a friendly airbase. The AJ-1 was a three-seat, high-wing monoplane with tricycle landing gear. To facilitate carrier operations, the outer wing panels and the tailfin could be manually folded. It was fitted with two 2,300-brake-horsepower (1,700 kW) Pratt & Whitney R-2800-44W Double Wasp piston engines, mounted in nacelles under each wing with a large turbocharger fitted inside each engine nacelle, and a 4,600-pound-force (20,000 N) Allison J33-A-10 turbojet was fitted in the rear fuselage. The jet engine was only intended for takeoff and maximum speed near the target, and was fed by an air inlet on top of the fuselage that was normally kept closed to reduce drag.[6] To simplify the fuel system, the jet engine used piston engine avgas rather than jet fuel. One 201-US-gallon (760 L; 167 imp gal) self-sealing fuel tank was housed in the fuselage, and another 508-US-gallon (1,920 L; 423 imp gal) tank was located in each wing. The aircraft usually carried 300-US-gallon (1,100 L; 250 imp gal) tip tanks and it could house three fuel tanks in the bomb bay with a total capacity of 1,640 US gallons (6,200 L; 1,370 imp gal). Other than its 12,000-pound (5,400 kg) bombload, the bomber was unarmed. Two of the three prototypes crashed during testing, but their loss did not materially affect the development of the aircraft as the first batch of Savages had been ordered on 6 October 1947. The most significant difference between the XAJ-1 and the production aircraft was the revision of the cockpit to accommodate a third crewman in a separate compartment. The first flight by a production aircraft occurred in May 1949 and Fleet Composite Squadron 5 (VC-5) became the first squadron to receive a Savage in September. The squadron participated in testing and evaluating the aircraft together with the Naval Air Test Center (NATC) in order to expedite the Savage's introduction into the fleet. The first carrier takeoff and landing made by the bomber took place from the USS Coral Sea on 21 April and 31 August 1950, respectively. Many, if not most, surviving AJ-1s had their tails upgraded to the improved AJ-2 configuration. A photo-reconnaissance version of the Savage, initially known as the AJ-1P, but later designated as the AJ-2P, was ordered on 18 August 1950. It had improved R-2800-48 piston engines and the tail was redesigned to add 1 foot (30 cm) of height to the tailfin. The 12° dihedral of the tail stabilizers was eliminated and the rudder enlarged which slightly lengthened the aircraft. Early AJ-2Ps retained the three-man crew, but late-model aircraft added a fourth aft-facing crewman to the upper cockpit. The Savage's internal fuel capacity was also increased. The nose of the aircraft was remodeled with a prominent "chin" to accommodate a forward-looking oblique camera and a variety of oblique and vertical cameras could be fitted in the bomb bay. Photoflash bombs could be carried for night photography missions. The AJ-2 incorporated all of the changes made to the late model AJ-2P and 55 aircraft were ordered on 14 February 1951. The AJ-2 deleted the separate compartment for the third crewman, but retained the third seat in the cockpit from the AJ-2P. For details of operational history an the 13 variants, click here. All up, a total of 143 were built.

The Fieseler Fi 167 was a 1930s German biplane torpedo and reconnaissance bomber designed for use from the Graf Zeppelin class aircraft carriers under construction from 1936 to 1942. In early 1937, the Reichsluftfahrtministerium (German Ministry of Aviation) issued a specification for a carrier-based torpedo bomber to operate from Germany's first aircraft carrier, the Graf Zeppelin construction of which had started at the end of 1936. The specification was issued to two aircraft producers, Fieseler and Arado, and demanded an all-metal biplane with a maximum speed of at least 300 km/h (186 mph), a range of at least 1,000 km (631 mi) and capable both of torpedo and dive-bombing. By mid-1938 the Fiesler design proved to be superior to the Arado design, the Ar 195. The aircraft exceeded by far all requirements, had excellent handling capabilities and could carry about twice the required weapons payload. Like the company's better known Fieseler Fi 156 Storch, the Fi 167 had surprising slow-speed capabilities; under the right conditions, the plane would be able to land almost vertically on a moving aircraft carrier. During a test flight, Gerhard Fieseler himself let the plane drop from 3,050 to 30 metres (10,000 to 100 ft) while staying above the same ground point. For emergency landings at sea the Fi 167 could jettison its landing gear, and airtight compartments in the lower wing would help the aircraft stay afloat at least long enough for the two-man crew to evacuate. Two prototypes (Fi 167 V1 and V2) were built, followed by twelve pre-production models (Fi 167 A-0) which had only slight modifications from the prototypes.

The Aermacchi M-346 Master is a family of military twin-engine transonic advanced jet trainers and light combat aircraft. Originally co-developed with Yakovlev as the Yak/AEM-130, the partnership was dissolved in 2000 and then Alenia Aermacchi proceeded to separately develop the M-346 Master, while Yakolev continued work on the Yakovlev Yak-130. The first flight of the M-346 was performed in 2004. The type is currently operated by the air forces of Italy, Israel, Singapore, Greece, Turkmenistan and Poland. Since 2016 the manufacturer became Leonardo-Finmeccanica as Alenia Aermacchi merged into the new Finmeccanica, finally rebranded as Leonardo in 2017. The M-346 is designed for the main role of lead-in fighter trainer, in which aircraft's performance and capabilities are used to deliver pilot training for the latest generation of combat fighter aircraft. Powered by a pair of Honeywell F124 turbofan dry engines, designed to reduce acquisition and operating costs, it is capable of transonic flight without using an afterburner; Alenia Aermacchi has claimed that the M-346's flight performance to be "second only to afterburner-equipped aircraft". During the design process, the twin concepts of "design-to-cost" and "design-to-maintain" were adhered to, reducing acquisition and operational costs; the per flying hour costs of the M346 are reportedly one-tenth of those of the Eurofighter Typhoon. Outside of the training role, the M-346 was designed from the onset to accommodate additional operational capabilities, including combat missions such as close air support and air policing duties. The combat capable M-346FA can perform ground attack, homeland defence and air policing missions and reconnaissance. Various munitions and stores can be carried, including IRIS-T or AIM-9 Sidewinder air-to-air missiles, various air-to-surface missiles, anti-ship missiles, free-fall and laser-guided bombs and rockets, a 12.7 mm gun pod, reconnaissance and targeting pods, and electronic warfare pods; weapon aiming is performed using the Helmet Mounted Display and the multifunction displays. All main systems are duplicated, and the flight system reconfigurable, to increase survivability and functionality in the event of battle damage being sustained.[28] The aircraft has a maximum range of 1,375 nautical miles when outfitted with a maximum of three external fuel tanks, this can be extended via in-flight refuelling via a removable refuelling probe.

M-346LCA (Light Combat Aircraft) Armed variant offered to Poland as a replacement for aging Su-22. Designation no longer in use. M-346FT (Fighter Trainer) Multirole variant capable of switching between training and combat operations. New features include a new tactical datalink system and different armament capability, but do not include physical changes to the hardware. M-346FA (Fighter Attack) Multirole variant capable of air-to-air and air-to-surface combat with a 3 tonne payload spread over 7 hardpoints, advanced Grifo-M346 radar radar, countermeasures and stealth features including engine intake grids and radar-absorbing coatings on the canopy and wing leading edge. It is being marketed as a light attack aircraft also suitable for aggressor and companion training purposes. The aircraft was revealed on June 18, 2017, in a static display at that year's Paris Air Show. The aircraft is being marketed for export to South American and East Asian countries, and is claimed to be able to carry out operational missions at far lower costs than those of front-line fighters. T-100 Designation used for the United States Air Force's T-X program.

The Bristol Bombay was a British troop transport aircraft adaptable for use as a medium bomber flown by the Royal Air Force (RAF) during the Second World War. The Bristol Bombay was built to Air Ministry Specification C.26/31 which called for a monoplane bomber-transport aircraft to replace the Vickers Valentia biplane in use in the Middle East and India. The aircraft was required to be capable of carrying 24 troops or an equivalent load of cargo as a transport, while carrying bombs and defensive guns for use as a bomber. This dual-purpose design concept was common to British pre-war designs. Other entries for the specification were the Armstrong Whitworth A.W.23 and the Handley Page HP.52. Bristol's design, the Type 130, was a high-wing cantilever monoplane of all-metal construction. Bristol's previous monoplane design, the 1927 Bagshot, had suffered from lack of torsional rigidity in the wings leading to aileron reversal. This led to an extensive research program at Bristol which resulted in a wing design with a stressed metal skin rivetted to an internal framework consisting of multiple spars and the ribs. This was the basis of the Bombay's wing, which had seven spars, with high-tensile steel flanges and alclad webs. The aircraft had a twin-tail and a fixed tailwheel undercarriage. The aircraft's crew consisted of a pilot, who sat in an enclosed cockpit, a navigator/bomb-aimer, whose working position was in the nose, and a radio-operator/gunner, who divided his time between the radio operator's position behind the cockpit and a gun turret in the nose. When the aircraft was operated as a bomber, an additional gunner was carried to man the tail gun position. In the prototype, this position was equipped with a Lewis gun on a Scarff ring but in production aircraft, both gun positions were hydraulically-operated gun turrets each armed with a Vickers K machine gun. Eight 250-pound (110 kg) bombs could be carried on racks under the fuselage. A prototype Type 130 was ordered in March 1933 and first flew on 23 June 1935, powered by two 750 horsepower (560 kW) Bristol Pegasus III radial engines driving two-bladed propellers. Testing was successful and an order for 80 was placed as the Bombay in July 1937. These differed from the prototype in having more powerful (1,010 hp (750 kW)) engines driving three-bladed Rotol variable-pitch propellers, discarding the wheel spats fitted to the undercarriage main wheels in the prototype. As Bristol's Filton factory was busy building the more urgent Blenheim light bomber, the production aircraft were built by Short & Harland (owned by Short Brothers and Harland and Wolff) of Belfast. The complex nature of the Bombay's wing delayed production at Belfast. The first Bombay was not delivered until 1939 and the last 30 were cancelled. No 1 Air Ambulance Unit (No 1 AAU) of the RAAF was formed at Laverton, VIC on 15 February 1941 and was one of a small number of RAAF units designated to operate under RAF control. Amongst other types, it operated the Bombay from February 1943 to February 1944 when the unit was withdrawn from the Western Desert. The unit commenced operations from Gaza in August 1941 initially operating de Havilland DH.86, Bristol Bombay, Lockheed Lodestar and Grumman Goose types. It supported Commonwealth units during the North African campaign, and operated during the Tunisian campaign and the Allied invasion of Sicily. The Bombays were received from No 216 Squadron RAF, which re-equipped with the Vickers Wellington. However, the Bombay was slow, suffered mechanical problems, and made its last evacuation operation in November 1943. The survivors of the type were used to carry medical supplies up until January 1944. Bombays evacuated over 2,000 wounded during the Allied invasion of Sicily in 1943, and one crew was credited with carrying 6,000 casualties from Sicily and Italy before the type was finally withdrawn from use in 1944.

Unbuilt. Type 137B Combi version of Type 137A. Unbuilt. Type 144 Unbuilt development with retractable undercarriage proposed for Specification B.4/34 (won by Handley Page Harrow). A total of 51 units were built.

The CallAir Model A is a light aircraft from the US manufacturer CallAir Inc., which was developed in the early 1940s and whose agricultural aircraft variant was built until 1984. Reuel T. Call, an aviation enthusiast rancher and shipper from Wyoming , purchased a 1933 open- cockpit Kinner Sportster , which he transferred from the Glendale factory in the middle of winter. He was so enthusiastic about the machine's performance in the high mountains that in 1937 he and his brothers decided to design their own machine, the Call-Air, based on the Sportster. The first version of the Model A used an 80 hp Continental A-80 for its first flight in the winter of 1940 and was intended for use by ranchers and farmers in high-altitude, mountainous areas. CallAir's factory airfield was at an altitude of 1,900 m. In July 1941, the prototype received a more powerful Lycoming engine with 100 hp. Series production was supposed to begin in 1942, but could not begin because the USA entered the war and the associated cessation of civil aircraft construction. The Call family waited until 1946 to introduce the improved A-2 variant with a 125 hp engine, which quickly became a sales success in the northwestern United States. Since the materials for construction were difficult to obtain, Call bought the rights to the Interstate Cadet primarily because of the materials still available at Interstate. In 1947, the A-3 version received its type certification with a 125 hp Continental engine, followed by the A-4 with a 135 hp engine . With the A-5 and A-6, agricultural aircraft variants of the model were created for the first time. In total, CallAir's production of the Model A amounted to 140 series units in addition to the prototype. Divided into the variants, these were: 4 A-1, 13 A-2, 15 A-3, 30 A-4, 45 A-5, 19 A-6, 3 A-7. Another 11 copies have no variant assignment. In 1962, Intermountain Manufacturing Co. (IMCO) purchased CallAir at a public auction. IMCO developed the IMCO CallAir A-9 , a modified variant of the A-5 and A-6, which was delivered at a rate of one per week from March 1963. The biggest change compared to the original design was the relocation of the spray container (hopper) between the engine and cockpit for safety reasons. IMCO produced 78 A-9s. IMCO was taken over by Rockwell Standard 's Aero Commander division in 1966 , which also received the production rights for the A-9. Aero Commander marketed the A-9 as the Quail Commander . Since 1965, Aero Commander also produced the Aero Commander Ag Commander , referred to as Aero Commander Thrush Commander from 1967 , so confusion can arise here. In 1967, Rockwell-Standard merged with North American Aviation . On April 23, 1971, North American Rockwell (NAR) announced that the newly formed Aeronautica Agricola Mexicana SA (AAMSA), in which NAR held a 30% interest, would acquire the production rights, tools and materials for the Sparrow Commander and the Quail Commander bought. At AAMSA, the further developed IMCO CallAir A-9 continued to be built as the AAMSA A9B-M Quail until 1984. Versions A prototype 80 hp Continental A-80, first flight in 1940 A-1 Four-cylinder Lycoming O-235-A or -B (100 hp), 4 examples, type certificate ATC #758 on July 26, 1944 A-2 Four-cylinder Lycoming O-290-A (125 hp), type certificate July 31, 1946 A-3 Six-cylinder Continental C-125-2 (125 hp), type certificate November 6, 1947 A-4 Four-cylinder Lycoming O-320-A2A (150 hp), first flight December 14, 1954 A-5 Agricultural aircraft variant with 150 HP, 2 people on tandem seats on the left side, spray container on the right in the fuselage A-6 Agricultural aircraft variant with 180 hp, first flight December 18, 1957, like A-5 but larger fuel capacity A-7 Similar to A-5, but powered by a Continental W670-240 radial engine .

The Short Solent is a passenger flying boat that was produced by Short Brothers in the late 1940s. It was developed from the Short Seaford, itself a development of the Short Sunderland military flying boat design. The first Solent flew in 1946. New Solents were used by BOAC and TEAL, production ending in 1949. Second-hand aircraft were operated until 1958 by a number of small airlines such as Aquila Airways. The Short S.45 Solent was a high-wing monoplane flying boat of aluminium construction. Power was provided by four Bristol Hercules engines. The aircraft could be fitted for 24 passengers with day and night accommodation or 36 day passengers. The cabins (four on the lower deck and two on the upper) could be used to sleep four or seat six. The upper deck included a lounge/dining area next to kitchen; the lower deck had two dressing rooms, toilets and three freight compartments. The flight crew was five (two pilots, navigator, and radio operator with the flight engineer in a separate compartment behind the flight deck opposite crew rest berths) and there were two stewards to attend to the passengers. The Solent II introduced by BOAC could carry 34 passengers and 7 crew. Between 1948 and 1950, BOAC operated their Solents on the three-times weekly scheduled service from Southampton to Johannesburg taking a route down the Nile and across East Africa. The journey took four days, including overnight stops. The Solents replaced Avro Yorks running the service. The last Solent-operated service on the route departed from Berth 50 at Southampton on 10 November 1950, bringing BOAC's flying-boat operations to an end. Tasman Empire Airways Limited (TEAL) operated five Solent IVs between 1949 and 1960 on their scheduled routes between Sydney, Fiji, Auckland and Wellington. The last TEAL Solent service was flown between Fiji and Tahiti on 14 September 1960 by ZK-AMO, RMA Aranui, which is now preserved. The TEAL Solents could carry 45 passengers and all versions of the type provided a great deal of space and luxury compared with contemporary or modern land-based aircraft. Variants Solent II Civilian version for BOAC of the Short Seaford, 12 aircraft built at Rochester Solent III Converted S.45 Seaford. 7 aircraft – 6 at Queen's Island, Belfast, 1 at Hamble Solent IV Powered by Bristol Hercules 733, four aircraft built at Belfast

The Supermarine Seagull III was a British designed and built amphibian bi-plane. The prototype, the Seagull I, was developed in 1921 and this led to improvements for the construction of 25 Seagull II, in 1922, for use by the Royal Navy and Royal Air Force. Further improvements resulted in the Seagull III, fitted with a Napier Lion V engine, becoming available in 1925. The Royal Australian Air Force (RAAF) ordered six of these aircraft in 1925 to replace its Fairey IIID seaplanes at a cost of £ 8,000 each. The aircraft were freighted to Australia arriving in mid-1926 with the first test flight conducted in June of that year. A further three aircraft were ordered in 1927. The Seagull was constructed from timber and canvas and the Australian version had a radiator modified for tropical usage. The lower wing was set in the shoulder position and the engine was mounted in a nacelle slung from the upper wing; powering a four-blade propeller in ‘tractor’ configuration. The aircraft carried a crew of three with the pilot being a RAAF officer, the observer (navigator) a naval officer and the telegraphist air gunner a naval rating. The Seagulls were allocated to 101 Flight RAAF and three aircraft took part in the Great Barrier Reef Survey during 1926-27 and were based at Bowen in far north Queensland. Due to their size and the logistics / engineering needs the aircraft were based ashore and carried out regular flights over the reef to conduct photographic surveys in support of survey work being conducted by HMA Ships Geranium and Moresby. The Seagulls were normally located at RAAF Base Point Cook, Victoria but following the commissioning of the sea plane carrier HMAS Albatross, in January 1929, they were embarked regularly for training exercises; where the aircraft proved very useful in spotting, and signalling corrections, for the fall of shot during gunnery practice firings. The Seagulls were also employed on reconnaissance flights where they were also adept in locating other vessels and signalling, via wireless telegraphy, the location of the ships. The range of the wireless telegraphy equipment was however only 30 kilometres in good weather conditions. Number ordered - 9. For further information on the Seagull III, click here.

At the height of the Great Depression, aircraft executive Walter H. Beech and airplane designer Ted A. Wells joined forces to collaborate on a project to produce a large, powerful, and fast cabin biplane built specifically for the business executive. The Beechcraft Model 17, popularly known as the "Staggerwing", was first flown on November 4, 1932. During its heyday, it was used as an executive aircraft, much as the private jet is now, and its primary competition were the Waco Custom Cabin and Waco Standard Cabin series of biplanes. The Model 17's unusual negative stagger wing configuration (the upper wing staggered behind the lower) and unique shape maximized pilot visibility and was intended to reduce interference drag between the wings (although it was later found to have negligible effect). The fabric-covered fuselage was faired with wood formers and stringers over a welded, steel tube frame. Construction was complex and took many man-hours to complete. The Staggerwing's retractable conventional landing gear, uncommon at that time, combined with careful streamlining, light weight, and a powerful radial engine, helped it perform well. In the mid-1930s, Beech undertook a major redesign of the aircraft, to create the Model D17 Staggerwing. The D17 featured a lengthened fuselage that improved the aircraft's handling characteristics by increasing control leverage, and the ailerons were relocated to the upper wings, eliminating interference with the flaps. Braking was improved with a foot-operated brake linked to the rudder pedals. Number built: 785 For details of the operational history and numerous variants, click here.

The aircraft was developed as Type 142, a civil airliner, in response to a challenge from Lord Rothermere to produce the fastest commercial aircraft in Europe. The Type 142 first flew in April 1935, and the Air Ministry, impressed by its performance, ordered a modified design as the Type 142M for the Royal Air Force (RAF) as a bomber. Deliveries of the newly named Blenheim to RAF squadrons commenced on 10 March 1937. A development of the Type 142M was the Type 149 which Bristol named the Bolingbroke, retrospectively changed by the Air Ministry to Blenheim Mk IV and the Type 142M to the Blenheim Mk I. Fairchild Canada built the Type 149 under licence as the Bolingbroke. Blenheims Mk I and the Mk IV were adapted as fighters by the addition of a gun pack of four Browning .303 machine guns in the bomb bay. The Mk IV was used as a long range fighter and as a maritime patrol aircraft; both aircraft were also used as bomber/gunnery trainers. The Blenheim was one of the first British aircraft with an all-metal stressed-skin construction, retractable landing gear, flaps, a powered gun turret and variable-pitch propellers. The Mk I was faster than most fighters in the late 1930s but the advance in development of monoplane fighters made all bombers more vulnerable particularly if flown in daylight, though it proved successful as a night fighter. The Blenheim was effective as a bomber but many were shot down. Both Blenheim types were used by overseas operators, being licence built in Yugoslavia and Finland. On 10 March 1937, production deliveries to the RAF formally started; 114 Squadron became the first squadron to receive the Blenheim. On 13 January 1938, the Blenheim entered service with No. 30 Squadron, the first overseas squadron to receive the type; in early 1939, the first Blenheims arrived in India. From July 1936 onwards, various additional orders were placed for the Blenheim Mk I, including multiple orders for the export market. By the end of 1936, 1,568 aircraft were on order. In order to meet the demand, secondary assembly lines were established at Chadderton by Avro and at Speke by Rootes Securities. The aircraft was built under licence by overseas countries, including Finland, who completed a total of 55 aircraft, and Yugoslavia, which completed 16 aircraft with a further 24 in advanced stages of completion when Germany invaded Yugoslavia. Other countries also procured the Blenheim, including Romania, Greece and Turkey. By September 1939, orders for the Blenheim had risen to 2,088 aircraft. Total production of the Blenheim Mk I in England was 1,351 aircraft prior to the end of the production run in 1939; production had been terminated in favour of more advanced variants. Formal work on an extended-range reconnaissance version started as the Blenheim Mk II, which increased tankage from 278 gal (1,264 L) to 468 gal (2,127 L). Only one Blenheim Mk II was completed, as flight tests revealed the increase in speed to be marginal and not warranting further development. Another modification resulted in the Blenheim Mk III, which lengthened the nose, dispensing with the "stepless cockpit" format of the Mk.I, introducing a true windscreen in front of the pilot, to provide more room for the bomb aimer. This required the nose to be "scooped out" in front of the pilot to maintain visibility during takeoff and landing. Both modifications were combined, along with a newer version of the Mercury engine with 905 hp (675 kW). The turret acquired a pair of Brownings in place of the original single Vickers K gun, creating the Blenheim Mk IV. Bristol Blenheim MkI, IV & V aircraft served with three RAAF article XV Squadrons (454, 456 & 459) with RAF serials.
