The North American A-5 Vigilante is an American carrier-based supersonic bomber designed and built by North American Aviation (NAA) for the United States Navy. Before the 1962 unification of Navy and Air Force designations, it was designated A3J.

Development of the A-5 had started in 1954 as a private venture by NAA, who sought to produce a capable supersonic long-distance bomber as a successor to the abortive North American XA2J Super Savage. It was a large and complex aircraft that incorporated several innovative features, such as being the first bomber to feature a digital computer, while its ability to attain speeds of up to Mach 2 while carrying a nuclear strike payload was also relatively ambitious for the era.[2] The US Navy saw the value of such a bomber, leading to a contract for its full development and production being issued to the firm on 29 August 1956. The type performed its first flight just over two years later, on 31 August 1958.

The Vigilante was introduced by the US Navy during June 1961; it succeeded the Douglas A-3 Skywarrior as the Navy's primary nuclear strike aircraft, but its service in this capacity was relatively brief due to the deemphasising of manned bombers in American nuclear strategy. A far larger quantity of the RA-5C tactical strike reconnaissance variant were also procured by the service, which saw extensive service during the Vietnam War. It also established several world records in both long-distance speed and altitude categories. During the mid-1970s, the withdrawal of the type commenced after a relatively short service life, largely due to the aircraft being expensive and complex to operate, as well being a victim of post-Vietnam military cutbacks.

The North American F-100 Super Sabre is an American supersonic jet fighter aircraft that served with the United States Air Force (USAF) from 1954 to 1971 and with the Air National Guard (ANG) until 1979. The first of the Century Series of USAF jet fighters, it was the first USAF fighter capable of supersonic speed in level flight. The F‑100 was designed by North American Aviation as a higher performance follow-on to the F-86 Sabre air superiority fighter.

Adapted as a fighter-bomber, the F-100 was superseded by the high-speed F‑105 Thunderchief for strike missions over North Vietnam. The F‑100 flew extensively over South Vietnam as the air force's primary close air support jet until being replaced by the more efficient subsonic LTV A-7 Corsair II. The F‑100 also served in other NATO air forces and with other U.S. allies. In its later life, it was often referred to as the Hun, a shortened version of "one hundred".

The YF-100A first flew on 25 May 1953, seven months ahead of schedule. It reached Mach 1.04 in spite of being fitted with a de-rated XJ57-P-7 engine. The second prototype flew on 14 October 1953, followed by the first production F-100A on 9 October 1953. The USAF operational evaluation from November 1953 to December 1955 found the new fighter to have superior performance, but declared it not ready for wide-scale deployment due to various deficiencies in the design. These findings were subsequently confirmed during "Project Hot Rod" operational suitability tests.

Six F-100s arrived at the Air Proving Ground Command, Eglin Air Force Base in August 1954. The Air Force Operational Test Center was scheduled to use four of the fighters in operational suitability tests and the other two were to undergo armament tests by the Air Force Armament Center. The Tactical Air Division of AFOTC was conducting the APGC testing under the direction of project office Lieutenant Colonel Henry W. Brown. Initial testing was completed by APGC personnel at Edwards Air Force Base.

Particularly troubling was the yaw instability in certain regimes of flight which produced inertia coupling. The aircraft could develop a sudden yaw and roll which would happen too fast for the pilot to correct and would quickly over-stress the aircraft structure to disintegration. It was under these conditions that North American's chief test pilot, George Welch, was killed while dive testing an early-production F-100A (s/n 52-5764) on 12 October 1954.

Another control problem stemmed from handling characteristics of the swept wing at high angles of attack. As the aircraft approached stall speeds, loss of lift on the tips of the wings caused a violent pitch-up. This particular phenomenon (which could easily be fatal at low altitude where there was insufficient time to recover) became known as the "Sabre dance".

Nevertheless, delays in the Republic F-84F Thunderstreak program pushed the Tactical Air Command to order the raw F-100A into service. Tactical Air Command also requested that future F-100s be fighter-bombers, with the capability of delivering nuclear bombs.

It was developed in the 1960s as a special aircraft for counter-insurgency (COIN) combat, and one of its primary missions was as a forward air control (FAC) aircraft. It can carry up to 3,200 lb of external munitions, internal loads such as paratroopers or stretchers, and loiter for three or more hours.

The aircraft was initially conceived in the early 1960s through an informal collaboration between WH Beckett and Colonel KP Rice, U.S. Marine Corps, who met at Naval Air Weapons Station China Lake, California, and who also happened to live near each other. The original concept was for a rugged, simple, close air support aircraft integrated with forward ground operations. At the time, the U.S. Army was still experimenting with armed helicopters, and the U.S. Air Force was not interested in close air support.

The concept aircraft was to operate from expedient forward air bases using roads as runways. Speed was to be from very slow to medium subsonic, with much longer loiter times than a pure jet. Efficient turboprop engines would give better performance than piston engines. Weapons were to be mounted on the centerline to get efficient unranged aiming. The inventors favored strafing weapons such as self-loading recoilless rifles, which could deliver aimed explosive shells with less recoil than cannons, and a lower per-round weight than rockets. The airframe was to be designed to avoid the back blast.

The OV-10 has a central nacelle containing pilots and cargo, and twin booms containing twin turboprop engines. The visually distinctive feature of the aircraft is the combination of the twin booms, with the horizontal stabilizer that connects them.

The aircraft's design supported effective operations from forward bases. The OV-10 can perform short takeoffs and landings, including on aircraft carriers and large-deck amphibious assault ships without using catapults or arresting wires. Further, the OV-10 was designed to take off and land on unimproved sites. Repairs could be made with ordinary tools. No ground equipment was required to start the engines. And, if necessary, the engines would operate on high-octane automobile fuel with only a slight loss of power.

The North American T-2 Buckeye was the United States Navy's intermediate training aircraft, intended to introduce U.S. Navy and U.S. Marine Corps student naval aviators and student naval flight officers to jets.

 It entered service in 1959, and was replaced by the McDonnell Douglas T-45 Goshawk in 2008.

In 1956, the US Navy issued a requirement for a jet-powered basic trainer to replace its T-28 piston-engined aircraft. (Primary training for the US Navy remained the responsibility of the piston-engined Beechcraft T-34 Mentor while the jet-powered Lockheed T2V SeaStar provided more advanced training). North American Aviation won the US Navy's competition for the new training aircraft in mid-1956 with its NA-241 design. North American's design, designated the T2J-1 by the US Navy, was a mid-winged monoplane with trainee and instructor sitting in tandem on North American-built ejection seats, with the rear (instructor's) seat raised to give a good view over the trainee's head. The aircraft's unswept wing's structure was based on that of the FJ-1 Fury, while its control system was based on the T-28C. It was powered by a single Westinghouse J34-WE-46/48 turbojet, rated at 3,400 lbf (15 kN). While it had no built-in armament, the T2J-1 could accommodate two .50-inch gun pods, 100 lb (45 kg) practice bombs, or 2.75-inch rockets beneath the wings. The T-2's performance was between that of the U.S. Air Force's Cessna T-37 Tweet and the U.S. Navy's TA-4J Skyhawk.

The first T2J-1 flew on 31 January 1958, and the type entered service with Basic Training Group Seven, soon to become VT-7 at Naval Air Station Meridian in 1959. A second training group, VT-9 formed at Meridian in 1961.

The first version of the aircraft entered service in 1959 as the T2J-1. It was redesignated the T-2A in 1962 under the joint aircraft designation system. The aircraft was subsequently redesigned, and the single engine was replaced with two 3,000 lbf (13,000 N) Pratt & Whitney J60-P-6 turbojets in the T-2B. The T-2C was fitted with two 2,950 lbf (13,100 N) thrust General Electric J85-GE-4 turbojets. The T-2D and T-2E were export versions for the Venezuelan Air Force and Hellenic Air Force, respectively. The T-2 Buckeye (along with the TF-9J Cougar) replaced the T2V-1/T-1A SeaStar, though the T-1 continued in some uses into the 1970s.

There are two main models, the original F-5A and F-5B Freedom Fighter variants and the extensively updated F-5E and F-5F Tiger II variants. The design team wrapped a small, highly aerodynamic fighter around two compact and high-thrust General Electric J85 engines, focusing on performance and a low cost of maintenance. Smaller and simpler than contemporaries such as the McDonnell Douglas F-4 Phantom II, the F-5 cost less to procure and operate, making it a popular export aircraft. Though primarily designed for a day air superiority role, the aircraft is also a capable ground-attack platform. The F-5A entered service in the early 1960s. During the Cold War, over 800 were produced through 1972 for U.S. allies. Though at the time the United States Air Force (USAF) did not have a need for a light fighter, it did procure approximately 1,200 Northrop T-38 Talon trainer aircraft, which was based on Northrop's N-156 fighter design.

F-5 Tiger II

The Northrop F-89 Scorpion was an American all-weather, twin-engined interceptor aircraft built during the 1950s, the first jet-powered aircraft designed for that role from the outset to enter service. Though its straight wings limited its performance, it was among the first United States Air Force (USAF) jet fighters equipped with guided missiles and notably the first combat aircraft armed with air-to-air nuclear weapons (the unguided Genie rocket).

The Scorpion stemmed from a United States Army Air Forces (USAAF) Air Technical Service Command specification ("Military Characteristics for All-Weather Fighting Aircraft") for a night fighter to replace the P-61 Black Widow. The preliminary specification, sent to aircraft manufacturers on 28 August 1945, required two engines and an armament of six guns, either 0.60-inch (15 mm) machine guns or 20-millimetre (0.79 in) autocannon. The revised specification was issued on 23 November; it did not specify jet propulsion, but the desired maximum speed of 530 miles per hour (460 kn; 850 km/h) virtually dictated that all the submissions would be jet-powered. The aircraft was to be armed with aerial rockets stored internally and six guns split between two flexible mounts, four guns forward and two in the rear. Each mount had to be capable of 15° of movement from the longitudinal axis of the aircraft. Each mount's guns were to be automatically controlled by radar. For ground attack, it had to be capable of carrying 1,000-pound (454 kg) bombs and to be able to carry a minimum of eight rockets externally.

There were 15 variants to the F-89 and a total of 2,010 were built.

It is a flying wing design with a crew of two.

The bomber can deploy both conventional and thermonuclear weapons, such as up to eighty 500-pound class (230 kg) Mk 82 JDAM Global Positioning System-guided bombs, or sixteen 2,400-pound (1,100 kg) B83 nuclear bombs. The B-2 is the only acknowledged aircraft that can carry large air-to-surface standoff weapons in a stealth configuration. Twenty B-2s are in service with the United States Air Force, which plans to operate them until 2032 as of 2018, when the Northrop Grumman B-21 Raider is to replace it.

The B-2 is capable of all-altitude attack missions up to 50,000 feet (15,000 m), with a range of more than 6,000 nautical miles (6,900 mi; 11,000 km) on internal fuel and over 10,000 nautical miles (12,000 mi; 19,000 km) with one midair refueling. It entered service in 1997 as the second aircraft designed to have advanced stealth technology after the Lockheed F-117 Nighthawk attack aircraft. Though designed originally as primarily a nuclear bomber, the B-2 was first used in combat dropping conventional, non-nuclear ordnance in the Kosovo War in 1999. It later served in Iraq, Afghanistan, and Libya.

The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning (AEW) aircraft.

This twin-turboprop aircraft was designed and developed during the late 1950s and early 1960s by the Grumman Aircraft Company for the United States Navy as a replacement for the earlier, piston-engined E-1 Tracer, which was rapidly becoming obsolete.The aircraft's performance has been upgraded with the E-2B and E-2C versions, where most of the changes were made to the radar and radio communications due to advances in electronic integrated circuits and other electronics. 

The fourth major version of the Hawkeye is the E-2D, which first flew in 2007. The E-2 was the first aircraft designed specifically for its role, as opposed to a modification of an existing airframe, such as the Boeing E-3 Sentry. Variants of the Hawkeye have been in continuous production since 1960, giving it the longest production run of any carrier-based aircraft.

The E-2 also received the nickname "Super Fudd" because it replaced the WF (later E-1) "Willy Fudd". In recent decades, the E-2 has been commonly referred to as the "Hummer" because of the distinctive sounds of its turboprop engines, quite unlike that of turbojet and turbofan jet engines. In addition to U.S. Navy service, smaller numbers of E-2s have been sold to the armed forces of Egypt, France, Israel, Japan, Mexico, Singapore and Taiwan.

Grumman also used the basic layout of the E-2 to produce the Grumman C-2 Greyhound cargo aircraft.

The E-2 is a high-wing airplane, with one Allison T56 turboprop engine (5250 shp rating) on each wing and retractable tricycle landing gear. As with most carrier-borne airplanes, the E-2 is equipped with a tail hook for recovery (landing) and the nose gear can attach to a shuttle of the aircraft carrier's catapults for launch (takeoff). A distinguishing feature of the Hawkeye is its 24-foot (7.3 m) diameter rotating radar dome (rotodome) that is mounted above its fuselage and wings. This carries the E-2's primary antennas for its long-range radar and IFF systems. No other carrier-borne aircraft possesses one of these.

The Northrop Grumman (formerly Grumman) EA-6B Prowler is a twin-engine, four-seat, mid-wing electronic-warfare aircraft derived from the A-6 Intruder airframe.

The EA-6A was the initial electronic warfare version of the A-6 used by the United States Marine Corps and United States Navy. Development on the more advanced EA-6B began in 1966. An EA-6B aircrew consisted of one pilot and three Electronic Countermeasures Officers, though it was not uncommon for only two ECMOs to be used on missions. It was capable of carrying and firing anti-radiation missiles (ARMs), such as the AGM-88 HARM.

The Prowler was in service with the U.S. Armed Forces from 1971 until 2019. It has carried out numerous missions for jamming enemy radar systems, and in gathering radio intelligence on those and other enemy air defense systems. From the 1998 retirement of the United States Air Force EF-111 Raven electronic warfare aircraft, the EA-6B was the only dedicated electronic warfare plane available for missions by the U.S. Navy, the U.S. Marine Corps, and the U.S. Air Force until the fielding of the Navy's EA-18G Growler in 2009. Following its last deployment in late 2014, the EA-6B was withdrawn from U.S. Navy service in June 2015, followed by the USMC in March 2019.

Designed for carrier-based and advanced base operations, the EA-6B was a fully integrated electronic warfare system combining long-range, all-weather capabilities with advanced electronic countermeasures.[9] A forward equipment bay and pod-shaped fairing on the vertical fin housed the additional avionics equipment. It was the primary electronic warfare aircraft for the U.S Navy and U.S. Marine Corps. The EA-6B's primary mission was to support ground-attack strikes by disrupting enemy electromagnetic activity. As a secondary mission it could also gather tactical electronic intelligence within a combat zone, and another secondary mission was attacking enemy radar sites with anti-radiation missiles.

The Prowler had a crew of four, a pilot and three Electronic Countermeasures Officers (known as ECMOs). Powered by two non-afterburning Pratt & Whitney J52-P-408A turbojet engines, it was capable of speeds of up to 590 mph (950 km/h) with a range of 1,140 miles (1,840 km).

Design particulars included the refueling probe being asymmetrical, appearing bent to the right to improve pilot visibility over that of the A-6 Intruder. It contained an antenna near its root. The canopy had a shading of gold to protect the crew against the radio emissions that the electronic warfare equipment produces.

There are three primary Tornado variants: the Tornado IDS (interdictor/strike) fighter-bomber, the suppression of enemy air defences Tornado ECR (electronic combat/reconnaissance) and the Tornado ADV (air defence variant) interceptor aircraft.

The Tornado was developed and built by Panavia Aircraft GmbH, a tri-national consortium consisting of British Aerospace (previously British Aircraft Corporation), MBB of West Germany, and Aeritalia of Italy. It first flew on 14 August 1974 and was introduced into service in 1979–1980. Due to its multirole design, it was able to replace several different fleets of aircraft in the adopting air forces. The Royal Saudi Air Force (RSAF) became the only export operator of the Tornado in addition to the three original partner nations. A tri-nation training and evaluation unit operating from RAF Cottesmore, the Tri-National Tornado Training Establishment, maintained a level of international co-operation beyond the production stage.

The Tornado was operated by the Royal Air Force (RAF), Italian Air Force, and RSAF during the Gulf War of 1991, in which the Tornado conducted many low-altitude penetrating strike missions. The Tornados of various services were also used in The Bosnian War, Kosovo War, Iraq War, in Libya during the Libyan civil war, as well as smaller roles in Afghanistan, Yemen, and Syria. Including all variants, 990 aircraft were built.

The Panavia Tornado is a multirole, twin-engined aircraft designed to excel at low-level penetration of enemy defences. The mission envisaged during the Cold War was the delivery of conventional and nuclear ordnance on the invading forces of the Warsaw Pact countries of Eastern Europe; this dictated several significant features of the design. Variable wing geometry allowed for minimal drag during the low-level dash towards a well-prepared enemy. Advanced navigation and flight computers, including the then-innovative fly-by-wire system, greatly reduced the workload of the pilot during low-level flight and eased control of the aircraft. For long range missions, the Tornado has a retractable refuelling probe.

As a multirole aircraft, the Tornado is capable of undertaking more mission profiles than the anticipated strike mission; various operators replaced multiple aircraft types with the Tornado as a common type – the use of dedicated single role aircraft for specialist purposes such as battlefield reconnaissance, maritime patrol duties, or dedicated electronic countermeasures (ECM) were phased out – either by standard Tornados or modified variants, such as the Tornado ECR. The most extensive modification from the base Tornado design was the Tornado ADV, which was stretched and armed with long range anti-aircraft missiles to serve in the interceptor role.

Specifications below are for the GR4 variant, an upgrade of the interdictor/strike GR1 model.

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 Percival Pembroke is a British high-wing twin-engined light transport aircraft built by the Percival Aircraft Company, later Hunting Percival.

The Pembroke was a development of the Percival Prince civil transport. It had a longer wing to permit a higher fully laden weight. The prototype flew on 21 November 1952. Production was complete in early 1958.

It entered service with the Royal Air Force as the Percival Pembroke C.1 in 1953 to replace the Avro Anson for light transport duties. As with other RAF transports, the passenger seats are rearward-facing for improved safety.

Six were produced as the Pembroke C(PR).1 photographic reconnaissance aircraft. These saw use by No. 81 Squadron RAF during the Malayan Emergency. The RAF's Pembrokes were modified to extend their lifespan in 1970. The last unit to use them was No. 60 Squadron RAF based at RAF Wildenrath in Germany, these were withdrawn from use in 1988 and were replaced by the Hawker Siddeley Andover.

The Finnish Air Force operated two aircraft for aerial photography between 1956 and 1968, on behalf of the National Land Survey of Finland. One of the aircraft was destroyed when it hit a snow wall during landing in 1965. The other aircraft is currently stored at the Aviation Museum of Central Finland.

Total number built: 128.

The fourth of a line of tandem rotor helicopters designed and built by Piasecki Helicopter (later Boeing Vertol), it was a multi-mission helicopter, utilizing wheels, skis, or floats.

The H-21 was originally developed by Piasecki as an Arctic rescue helicopter. The H-21 had winterization features permitting operation at temperatures as low as −65 °F (−54 °C), and could be routinely maintained in severe cold weather environments.

Piasecki Helicopter designed and successfully sold to the United States Navy a series of tandem rotor helicopters, starting with the HRP-1 of 1944. The HRP-1 was nicknamed the "flying banana" because of the upward angle of the aft fuselage, which ensured that the large rotors could not strike the fuselage in any flight attitude. The name was later applied to other Piasecki helicopters of similar design, including the H-21.

In 1949, Piasecki proposed the YH-21 Workhorse to the United States Air Force (USAF), which was an improved, all-metal derivative of the HRP-1. Using two tandem, fully articulated three-bladed counter-rotating rotors, the H-21 was powered by one nine-cylinder Curtis-Wright R-1820-103 Cyclone supercharged 1,150 hp (858 kW) air-cooled radial engine.

For more information on the development and design, and the 17 variants, click here.

A key aim for the PC-21 was to allow jet aircraft pilots to perform the majority of their training using the type before converting to jet-powered types, allowing operators to make substantial savings. In order to achieve this aim, the new trainer was required to have an expanded performance envelope in terms of aerodynamics, cockpit equipment, flexibility, and ease of maintenance. In May 2002, Pilatus announced that it aimed for the PC-21 to capture 50% of the global trainer aircraft market between 2005 and 2030.

The Pilatus PC-21 is an advanced single-engine trainer aircraft; it is often referred to by Pilatus as being the "Twenty-first Century Trainer". The type can be applied for various training capacities, including basic flying training, advanced flight training, full mission management training, and embedded simulation/emulation. In order to perform these functions, the aircraft possesses a powerful, flexible, and cost-effective integrated training system; providing sufficient ease of use for inexperienced pilots while posing greater challenge to advanced pilots.

The aircraft features a tandem-seating arrangement (student in-front/instructor behind) in a bird strike-resistant glass canopy with allround vision. The cabin, which is pressurized, is equipped with an On-Board Oxygen Generation System (OBOGS), air conditioning, and Martin-Baker CH16C Zero-Zero ejection seats. The flight controls, which are fully balanced and harmonized, are optimized for ease of operation and overall effectiveness.

An anti-g system is also present in order to minimize the effects of high g-forces experienced during tactical training and aerobatic maneuvers. Pilots are able to spend a greater amount of time concentrating on the aircraft's external situation and upon mission data inputs due to an ergonomic design approach, ease-of-use controls, and clear visual/system data displays. In addition, a full autopilot and civil flight management system are also present.

The PC-21 was one of the submissions for the Royal Australian Air Force's project AIR 5428, which sought a replacement of its Pilatus PC-9s; in September 2015, it was announced that the consortium comprising Lockheed Martin, Pilatus and Hawker Pacific ("Team 21"), had won the bid to provide 49 PC-21s to the Australian Defence Force.

The PZL I-22 Iryda, otherwise known as the PZL M93 Iryda and PZL M96 Iryda, was a twin-engine, two-seat military jet trainer aircraft developed and produced by Polish aviation company PZL Mielec.

Work started on what would become the Iryda in 1976 as a successor to the indigenously-developed TS-11 Iskra jet trainer. First flying on 3 March 1985, the type would have a protracted development, partly due to the initial unavailability of its PZL K-15 turbojet engines. The Polish Air Force received the first K-15-powered Irydras in May 1995. However, aircraft deliveries were complicated by disputes over cost and performance, leading to multiple announcements, policy reversals, and groundings of the type. A fatal accident involving the type on 24 January 1996 fuelled criticism and undermined support for the programme.

In 1996, an agreement was struck to upgrade the existing aircraft to a new standard, flight testing of which commenced the following year. However, relations between PZL Mielec and the Polish Defense Ministry became so poor over the programme that legal action was initiated while the Iryda itself languished. In the late 1990s Polish Government support for the programme was withdrawn, and the handful of delivered aircraft were stored. Despite attempts to revive the programme by PZL Mielec, no orders have been forthcoming.

Number built    17 including prototypes

The PZL-Mielec M-28TD Bryza is a Polish-built maritime patrol and reconnaissance aircraft as a development of license-built Antonov An-28s.

The M28 is a twin-engined high-wing strutted monoplane with an all-metal airframe, twin vertical fins and a tricycle fixed landing gear. If an engine fails, a spoiler forward of the aileron opens automatically on the opposite wing. This limits the wing drop to 12° in five seconds instead of 30°.

It is capable of Short takeoff & landing (STOL) and hot and high altitude operations. Aerodynamically deployed leading edge slats when approaching stall speed enable a 64 kn (119 km/h) low stall speed and while the certification landing field is 1,640 ft (500 m), PZL has demonstrated landing in 512 ft (156 m). Inlet air ducts inertial separators and inverted configuration of the PZL-10S engines and the high wing configuration protect the engines and propellers against foreign object damage for unprepared runways operations.

The Raytheon T-1 Jayhawk is a twin-engined jet aircraft used by the United States Air Force for advanced pilot training. T-1A students go on to fly airlift and tanker aircraft. The T-400 is a similar version for the Japan Air Self-Defense Force.

The T-1A Jayhawk is a medium-range, twin-engine jet trainer used in the advanced phase of Air Force Joint Specialized Undergraduate Pilot Training for students selected to fly strategic/tactical airlift or tanker aircraft. It is used also for training Air Force Combat Systems Officers in high and low level flight procedures during the advanced phase of training. It also augmented or served in lieu of the T-39 Sabreliner in the Intermediate phase of US Navy/Marine Corps Student Naval Flight Officer training until the joint Air Force-Navy/Marine Corps training pipeline split in 2010 and now remains solely in operation with the U.S. Air Force, leaving the Navy with the Sabreliner pending its eventual replacement. The T-1 Jayhawk shares the same letter and number as the long retired T-1 SeaStar under the 1962 United States Tri-Service aircraft designation system.

The swept-wing T-1A is a military version of the Beechjet/Hawker 400A. It has cockpit seating for an instructor and two students and is powered by twin turbofan engines capable of an operating speed of Mach .78. The T-1A differs from its commercial counterpart with structural enhancements that provide for a large number of landings per flight hour, increased bird strike resistance and an additional fuselage fuel tank. A total of 180 T-1 trainers were delivered between 1992 and 1997.

The first T-1A was delivered to Reese Air Force Base, Texas, in January 1992, and student training began in 1993.

Another military variant is the Japan Air Self-Defense Force T-400 (400T) trainer, which shares the same type certificate as the T-1A.

The Republic RF-84F Thunderflash is a photo reconnaissance version of the F-84F, 715 built.

The second YF-84F prototype was completed with wing-root air intakes. These were not adopted for the fighter due to loss of thrust. However, this arrangement permitted placement of cameras in the nose and the design was adopted for the RF-84F Thunderflash reconnaissance version. The first YRF-84F was completed in February 1952. The aircraft retained an armament of four machine guns and could carry up to fifteen cameras. Innovations included computerized controls which adjusted camera settings for light, speed, and altitude, a periscope to give the pilot better visualization of the target, and a voice recorder to let the pilot narrate his observations. Being largely identical to the F-84F, the Thunderflash suffered from the same production delays and engine problems, delaying operational service until March 1954. The aircraft was retired from active duty in 1957, only to be reactivated in 1961, and finally retired from the ANG in 1972.

In addition to the US, RF84F's were operated by many NATO countries - Belgium (34), Taiwan (25), Denmark (23), France (88), Germany (108), Italy (78), Netherlands (24) and Norway (35).

The RFB Fantrainer (or Fan Trainer) is a two-seat flight training aircraft which uses a mid-mounted ducted fan propulsion system. Developed and manufactured by German aircraft company Rhein-Flugzeugbau GmbH (RFB), it has been used by the Luftwaffe and Royal Thai Air Force.

Development of the Fantrainer commenced during the 1970s. In Germany, it was selected as the winner of a competition for the Luftwaffe's Basic Trainer Requirement, having beat both the Pilatus PC-7 and Beechcraft Mentor. However, no orders were forthcoming from Germany as it had committed to buying American fighters (F4 Phantom and F-104 Starfighter) which included a deal for pilot training in the United States. At one point, German flag carrier Lufthansa also reportedly took an interest in the aircraft, noting its jet-like handling. Pilots have confirmed the type to be relatively fuel-efficient and capable of providing a true "jet feel" for a reasonable price. The Royal Thai Air Force operates the FT400 and FT600 versions, using it to train ab initio pilots who then went on to fly the Northrop F-5E fighter aircraft.

The RFB Fantrainer is a twin-seat trainer aircraft; its most distinctive feature is its propulsion system, a mid-mounted ducted fan. This reportedly delivers performance akin to aircraft harnessing conventional jet propulsion, but at significantly reduced costs; on average, the Fantrainer has one-tenth of the fuel consumption of the Dassault/Dornier Alpha Jet, a contemporary jet-powered trainer aircraft. Furthermore, RFB has claimed the type to be one-fifth as expensive to procure as the Cessna T-37 Tweet, a rival trainer, while delivering comparable performance (except for a slower top speed) at one-tenth of the fuel consumption. The design of the Fantrainer reportedly incorporates several features to increase effectiveness and reduce costs. Attention was also paid to ease of use, the engine is controlled via a single-lever power control with ground and flight idle stops, behaving much like a traditional turbojet unit; in general, both controls and instrumentation are clear and straightforward.

The engine and fan installation incorporates a freely-moving turbine, which necessitates constant-speed control over the fan along with the use of reduction gear to roughly halve the 6,000 rpm output of the engine to achieve a fan speed of 3,090 rpm; both of these were designed by British supplier Dowty Group. The constant speed of the five-bladed fan enables the use of a relatively simple blade profile. Various noise reduction measures were implemented, including the use of Hoffmann-sourced plastic-covered wooden blades and the adoption of a re-designed fan that used five blades instead of seven. The use of a foam-plastic rubbing strip enables the fan to maintain the optimum blade-tip-to-shroud gap, said to be one-thousandth of the fan's diameter according to RFB; the ring slot ensures smooth air flow even at high power and low airspeed, and can also open asymmetrically to cope with offset inflow when the Fantrainer is flown at a relatively high angle of attack. Number built 50.

It is commonly called the "Bone" (from "B-One").[3] It is one of three strategic bombers in the U.S. Air Force fleet as of 2020, the other two being the B-2 Spirit and the B-52 Stratofortress.

The B-1 was first envisioned in the 1960s as a platform that would combine the Mach 2 speed of the B-58 Hustler with the range and payload of the B-52, and was meant to ultimately replace both bombers. After a long series of studies, Rockwell International (now part of Boeing) won the design contest for what emerged as the B-1A. This version had a top speed of Mach 2.2 at high altitude and the capability of flying for long distances at Mach 0.85 at very low altitudes. The combination of the high cost of the aircraft, the introduction of the AGM-86 cruise missile that flew the same basic profile, and early work on the stealth bomber all significantly affected the need for the B-1. This led to the program being canceled in 1977, after the B-1A prototypes had been built.

The program was restarted in 1981, largely as an interim measure due to delays in the B-2 stealth bomber program, with the B-2 eventually reaching initial operational capability in 1997. This led to a redesign as the B-1B, which differed from the B-1A by having a lower top speed at high altitude of Mach 1.25, but improved low-altitude performance of Mach 0.96. The electronics were also extensively improved during the redesign, and the airframe was improved to allow takeoff with the maximum possible fuel and weapons load. The B-1B began deliveries in 1986 and formally entered service with Strategic Air Command (SAC) as a nuclear bomber in that same year. By 1988, all 100 aircraft had been delivered.

In the early 1990s, following the Gulf War and concurrent with the disestablishment of SAC and its reassignment to the newly formed Air Combat Command, the B-1B was converted to conventional bombing use. It first served in combat during Operation Desert Fox in 1998 and again during the NATO action in Kosovo the following year. The B-1B has supported U.S. and NATO military forces in Afghanistan and Iraq. The Air Force had 62 B-1Bs in service as of 2016. The B-1B is expected to continue to serve into the 2030s, with the Northrop Grumman B-21 Raider to begin replacing the B-1B after 2025. The B-1s in inventory are planned to be retired by 2036.

The Swedish Air Force, which had opted to procure the type for various roles, issued the aircraft with the designation Sk 60. The Sk 60 entered service in 1967, replacing the ageing De Havilland Vampire fleet. There were talks of buying Folland Gnat but it became a source of inspiration.

The Swedish Air Force bought a total of 150 aircraft and another 40 were exported to Austria, designated Saab 105Ö. The Saab 105 is also the aircraft used by Swedish Air Force display team Team 60 and was formerly used by two display teams of the Austrian Air Force, "Karo As" and "Silver Birds".

The Saab 105 was developed to function as a small and inexpensive multirole aircraft, which has been most typically used in a training capacity.[8] It is an all-metal twin-jet aircraft with a pressurized cabin. It features a T-tail configuration, modestly swept wings, and a pair of engines mounted on either side of the fuselage just underneath the wing.

The 105 can be outfitted with various armaments and equipment to perform a wide range of duties, most of which would be installed upon the aircraft's six underwing hardpoints. In a ground-attack/close air support capacity, the 105 can employ a combination of 135 mm, 127 mm, and 75 mm unguided rockets, air-to-ground missiles and assorted bombs, including napalm bombs; either a pair of 30 mm cannon or 7.62 mm guns may be installed using a series of gun pods. In the air defense role, AIM-9 Sidewinder air-to-air missiles can be employed in addition to the cannons. Additionally, for the purpose of carrying a maximum of two passengers, smaller ejector seats can be installed for the pilot and co-pilot while a small bench directly behind them can be used by the passengers. Generic and more specialized surveillance/reconnaissance missions can also be performed by the Saab 105, having the option of being fitted with radiation detection equipment for atmospheric sampling. With suitable equipment, the 105 could be readily converted between trainer and light attack roles.

The Saab 29 Tunnan (The Barrel), colloquially also Flygande Tunnan (The Flying Barrel), is an early jet-powered fighter aircraft designed and produced by the Swedish aircraft manufacturer Saab. It was the second turbojet-powered combat aircraft to be developed in Sweden, the first being the Saab 21R, and it was the first Western European fighter to be produced with a swept wing after the Second World War, only being preceded in Western Europe as a whole by the Messerschmitt Me 262 built during the conflict.

Work on what would become the Tunnan commenced in late 1945. The design, internally designated R 1001, had a barrel-like fuselage, giving it a destinctive rotund appearance, from which its name is derived. A relatively thin swept wing configuration was adopted after wartime aerodynamic research from Germany indicated its favourable high speed qualities. It was powered by the recently-developed de Havilland Ghost turbojet engine. The Swedish Air Force placed an initial order for three prototypes under the service designation J 29 during Autumn 1946. On 1 September 1948, the first prototype performed its maiden flight; flight testing proved the aircraft to exceed performance estimates in several aspects.

During May 1951, Bråvalla Wing (F 13) received the first production aircraft. Five principal variants of the Tunnan were produced; the first model to enter service being the J 29A fighter, the more capable J 29B and J 29E fighters, and finally the afterburner-equipped J 29F fighter, which was the final fighter variant to be built. A dedicated aerial reconnaissance model, the S 29C, was also operated. During the 1960s, several J 29Bs saw combat while were stationed in the Republic of Congo as Sweden's contribution to a UN peacekeeping mission (ONUC). The Austrian Air Force also operated the type. In service, the J 29 proved to be relatively fast and agile. The Swedish Air Force operated the type in both fighter and fighter-bomber roles into the 1970s.

The Saab 29 Tunnan was the first Swedish aircraft to be specifically designed to use jet propulsion. Sweden's first jet fighter, the Saab 21R, had been modified from the piston-engined Saab 21. It is a small, chubby aircraft with a single round air intake in the nose, with the pilot under a bubble canopy directly above the air intake duct on the upper-forward section of the fuselage. It has a very thin mid-mounted moderately swept two-spar wing which is a single structure attached to the fuselage by four bolts. The undercarriage is hydraulically operated, and was designed to be suitable for use from rough airstrips. To improve pilot survivability, the Tunnan used an ejection seat Saab developed in 1943, with an explosive jettisoning system for the canopy.

The Tunnan is powered with a single 22.4 kN (5,000 lbf) de Havilland Ghost turbojet which have a top speed in excess of 1,050 km/h (650 mph), better performance than Sweden's de Havilland Vampires. The engine was bolted to the fuselage at three points and a special trolley was used to remove the engine for maintenance. The final version had an afterburner, the first successful one used with a British jet engine. A total of 661 units were built.

Improvements were made to the wing to incorporate a dog-tooth leading edge, raising the critical Mach number. From 1963 onwards, all frontline J 29Fs were equipped with AIM-9 Sidewinder infrared-seeking air-to-air missiles.

The Saab 32 Lansen (English: "The Lance[Nb 1][3]) is a two-seat, transonic military aircraft designed and manufactured by the Swedish aircraft manufacturer Saab AB.

Development of the Lansen commenced in late Autumn 1946 as a successor to the Saab B 18/S 18 attack aircraft, although an initial contract for the design and mockup of Saab's proposed P1150 design was not issued until December 1948. As the design was refined, plans to use the indigenous STAL Dovern turbojet engine were put aside due to technical difficulties in favour of the license-built Rolls-Royce Avon powerplant instead. On 3 November 1952, the first prototype performed its maiden flight; following flight testing and several refinements, series production of the type commenced during the following year.

Deliveries of the Lansen to the Swedish Air Force (Flygvapnet) took place between 1955 and 1960. It was the service's first twin-seat jet aircraft as well as the first to be equipped with an integrated search radar. Three principal variants of the Lansen were produced, these being for attack (A 32A), fighter (J 32B), and reconnaissance (S 32C) missions. Later built aircraft were equipped with a more powerful model of the Avon engine and increasingly capable electronics. During its lengthy operational life, the Lansen also served in secondary roles, including as an electronic warfare platform, target tug, and research aircraft. The majority were retired during the 1990s following the end of the Cold War.

The Saab 32 Lansen had a straightforward general arrangement, being one of the first aircraft in the world to be specifically developed to fly attack missions. From the outset, it was designed to effectively accommodate the installation of electronic warfare and various weapons systems. The aircraft could be armed with a total of four 20 mm cannon, as well as wing pylons for various calibers of rockets and assorted bombs. The J 32 variant carried four 30 mm ADEN cannons while the A 32 ("A" stands for attack) had an armament of four 20 mm Bofors m/49 cannon hidden under flaps in the nose. The J 32 differed substantially from the other variant, Saab describing it as "to all intents a new aircraft", being fitted with a more powerful engine and newer armaments and different radar.

It was the first fully supersonic aircraft to be deployed in Western Europe and the first aircraft to do the Cobra maneuver.

The Draken was developed during the 1940s and 1950s to replace Sweden's first generation of jet-powered fighter aircraft, the Saab J 29 Tunnan and, later, the fighter variant (J 32B) of the Saab 32 Lansen. It featured an innovative double delta wing; in order to test this previously-unexplored aerodynamic feature, a sub-scale test aircraft, the Saab 210, was produced and flown. Developed in Sweden, the Draken was introduced into service with the Swedish Air Force on 8 March 1960. It received the designation J 35, the prefix J standing for Jaktflygplan (Pursuit-aircraft) – the Swedish term for fighter. Early models were intended purely to perform air defence missions, the type being considered to be a capable dogfighter for the era.

The Draken functioned as an effective supersonic fighter aircraft of the Cold War period. In Swedish service, it underwent several upgrades, the ultimate of these being the J 35J model. By the 1980s, the SAF's Drakens had largely been replaced by the more advanced Saab 37 Viggen fighter, while the introduction of the more capable Saab JAS 39 Gripen fighter was expected in service within a decade, although delayed. As a consequence of cutbacks and high maintenance costs, the SAF opted to retire the Draken during December 1999. The type was also exported to Austria, Denmark, Finland, and the United States; the last operated the type as a training aircraft for test pilots.

The Saab 35 Draken is a fighter aircraft, equipped with a distinctive double delta wing. According to Flight International, it is difficult to differentiate between the fuselage and the wing. The design anticipates what would later be known as a ‘blended wing-body’. The fuselage has a circular section, and the inboard portion of the wing is a large-chord surface which extended almost to the engine intakes. It was possible to dispense with a tailplane, resulting in a clean, simple overall design. The leading edge of the inner wing was swept back 80° for high-speed performance, and the outer wing 60° for good performance at low speeds. Number built - 651 (all variants).
