The Fairchild T-46 was an American light jet trainer aircraft of the 1980s. It was cancelled in 1986 with only three aircraft being produced.
The United States Air Force (USAF) launched its Next Generation Trainer (NGT) program to replace the Cessna T-37 Tweet primary trainer in 1981. [1] Fairchild-Republic submitted a shoulder-winged monoplane with a twin tail, powered by two Garrett F109 turbofans and with pilot and instructor sitting side by side. [2] Part of the rationale was an expectation of increasing levels of general aviation traffic. A pressurized trainer would permit training at higher altitude, leading to fewer restrictions on the new pilots.
In order to validate the proposed aircraft's design, and to explore its flight handling characteristics, Fairchild Republic contracted with Ames Industries of Bohemia, New York to build a flyable 62% scale version. Burt Rutan's Rutan Aircraft Factory in Mojave, California was contracted to perform the flight test evaluations, with test pilot Dick Rutan doing the flying. The scale version was known at Rutan as the Model 73 NGT, this flying on 10 September 1981. [3] One requirement was for the aircraft to be able to go into a spin, but to also have easy recovery from the spin. This was demonstrated using the Model 73 NGT.
Fairchild's design, to be designated T-46, was announced winner of the competition on 2 July 1982, [2] with the USAF placing an order for two prototypes and options for 54 production aircraft. [4] It was planned to build 650 T-46s for the USAF by 1991. [5]
The aircraft first flew on 15 October 1985, [6] six months later than originally programmed date of 15 April. Costs had increased significantly during the development process, with the predicted unit cost rising from $1.5 million in 1982 to $3 million in February 1985. [5] The 1985 Gramm–Rudman–Hollings Balanced Budget Act mandated spending cuts for the US government in an attempt to limit the national debt, [5] and while testing did not reveal any major problems, [7] Secretary of the Air Force Russell A. Rourke cancelled procurement of the T-46, while allowing limited development to continue. [5] While attempts were made in Congress to reinstate the program, which resulted in the FY 1987 budget being delayed, an amendment was passed to the 1987 Appropriations Bill to forbid any spending on the T-46 until further evaluation of the T-46 against the T-37 and other trainers took place. [8]
The project was cancelled a little more than a year later, for reasons that largely remain controversial[ citation needed ]. The T-46 was the last project of the Fairchild Republic Corporation, and after the program termination Fairchild had no more income. Without any new contracts and the NGT program cancelled, the company closed the Republic factory in Farmingdale, New York, bringing 60 years of Fairchild aircraft manufacturing to an end.
The aircraft itself featured a side-by-side configuration, a twin (or "H") tail (similar to the company's A-10), ejection seats, pressurization, and two turbofan engines. Had it gone into full production the NGT program called for 650 aircraft being built up to 1992. There was potential for some overseas sales as well, such as in the light ground attack role in addition to its role as a trainer. [9]

The Boeing KC-135 Stratotanker is an American military aerial refueling tanker aircraft that was developed from the Boeing 367-80 prototype, alongside the Boeing 707 airliner. It has a narrower fuselage and is shorter than the 707. Boeing gave the aircraft the internal designation of Model 717. The KC-135 was the United States Air Force's first jet-powered refueling tanker and replaced the KC-97 Stratofreighter. The KC-135 was initially tasked with refueling strategic bombers, but it was used extensively in the Vietnam War and later conflicts such as Operation Desert Storm to extend the range and endurance of US tactical fighters and bombers.
The Lockheed C-5 Galaxy is a large military transport aircraft designed and built by Lockheed, and now maintained and upgraded by its successor, Lockheed Martin. It provides the United States Air Force (USAF) with a heavy intercontinental-range strategic airlift capability, one that can carry outsized and oversized loads, including all air-certifiable cargo. The Galaxy has many similarities to the smaller Lockheed C-141 Starlifter and the later Boeing C-17 Globemaster III. The C-5 is among the largest military aircraft in the world.
The Cessna T-37 Tweet is a small, economical twin-engined jet trainer aircraft. It was flown for decades as a primary trainer of the United States Air Force (USAF) as well as in the air forces of several other nations.
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 Fairchild C-123 Provider is an American military transport aircraft designed by Chase Aircraft and then built by Fairchild Aircraft for the U.S. Air Force. In addition to its USAF service, which included later service with the Air Force Reserve and the Air National Guard, it also went on to serve most notably with the U.S. Coast Guard and various air forces in Southeast Asia. During the War in Vietnam, the C-123 was used to deliver supplies, to evacuate the wounded, and also used to spray Agent Orange.
The Northrop YA-9 was a prototype attack aircraft developed for the United States Air Force A-X program. The YA-9 was passed over in preference for the Fairchild Republic YA-10 that entered production as the A-10 Thunderbolt II.
The Dassault/Dornier Alpha Jet is a light attack jet and advanced jet trainer co-manufactured by Dassault Aviation of France and Dornier Flugzeugwerke of Germany. It was developed specifically to perform trainer and light attack missions, as well as to perform these duties more ideally than the first generation of jet trainers that preceded it. Following a competition, a design submitted by a team comprising Breguet Aviation, Dassault Aviation, and Dornier Flugzeugwerke, initially designated as the TA501, was selected and subsequently produced as the Alpha Jet.
The Kawasaki T-4 is a Japanese subsonic intermediate jet trainer aircraft developed and manufactured by the commercial conglomerate Kawasaki Heavy Industries. Its sole operator is the Japan Air Self-Defense Force (JASDF), in part due to historic restrictions on the exporting of military hardware. In addition to its primary training mission, the T-4 has been used by the JASDF's Blue Impulse aerobatic team as well as liaison duties with most fighter units. The first XT-4 prototype flew on 29 July 1985, while the first production aircraft was delivered during September 1988.
The Fairchild SM-73 was a planned sub-sonic, jet-powered, long-range, ground-launched decoy cruise missile. XSM-73 was the designation for the development version. Development began in 1952 with conceptual studies and ended when the program was canceled in 1958 after 15 test flights but before any operational deployment. The operational concept was to base squadrons of XM-73s at various locations in the United States and if necessary launch the aircraft as part of a strategic bomber attack. The aircraft would fly autonomously under inertial guidance towards the target area, using radar reflectors and electronic countermeasures to imitate American bombers and thus confuse and saturate enemy air defenses. The program was cancelled because the missile was not able to simulate a B-52 bomber on radar.
The Fairchild C-26 "Metroliner" is the designation for the Fairchild Swearingen Metroliner series twin turboprop aircraft in the service of the United States military. It was not officially named by the US Armed Forces, but is unofficially known by the same name as its civilian counterpart. The C-26A is the military version of the Model SA227-AC Metro III; the C-26B is the military version of the Model SA227-BC Metro III and Model SA227-DC Metro 23; and UC-26C is the military designation for the Model SA227-AT Merlin IVC.
The Scaled Composites Triumph is a twin-engine, business jet prototype designed and built by Burt Rutan's Scaled Composites for Beechcraft. It was known officially as the Model 143, and internally at Scaled as the "Tuna". The aircraft is a three lifting surface design, with both a small canard, and a small conventional horizontal stabilizer in a T-tail configuration.
The Boeing Skyfox is an American twin-engined jet trainer aircraft, a highly upgraded development of the Lockheed T-33. It was designed as a primary trainer to compete with and replace the Cessna T-37 Tweet. Besides its primary role as a trainer, the aircraft was envisioned to have other roles as well, including ground attack. The program was started by the Skyfox Corporation in 1983, and was acquired by Boeing in 1986.
The Temco T-35 Buckaroo was designed in the late 1940s as an extremely low-cost trainer for commercial and military markets. Temco's failure to secure a United States Air Force order for the Buckaroo forced it to turn to non-U.S. governments to keep the production lines going, yet only a few export orders materialized.
The Fairchild Republic A-10 Thunderbolt II is a single-seat, twin-turbofan, straight-wing, subsonic attack aircraft developed by Fairchild Republic for the United States Air Force (USAF). In service since 1976, it is named for the Republic P-47 Thunderbolt, but is commonly referred to as the "Warthog" or simply "Hog". The A-10 was designed to provide close air support (CAS) to friendly ground troops by attacking armored vehicles, tanks, and other enemy ground forces; it is the only production-built aircraft designed solely for CAS to have served with the U.S. Air Force. Its secondary mission is to direct other aircraft in attacks on ground targets, a role called forward air controller-airborne; aircraft used primarily in this role are designated OA-10.
The Gulfstream American Peregrine 600 was a military trainer aircraft developed in the United States in the early 1980s but which did not progress further than prototype stage. Developed from the company's Hustler business aircraft, the Peregrine shared the same wings, empennage and rear fuselage, but had a new forward fuselage with side-by-side seating for the pilot and instructor. The aircraft was developed as a contender in the United States Air Force's Next Generation Trainer program, but was ultimately passed over in favor of the Fairchild T-46. Attempts to market it to the air forces of Australia, New Zealand, Japan, and China also proved unsuccessful, and the project was canceled in 1985. The wing and rear fuselage design was incorporated in the Gulfstream Aerospace Peregrine business aircraft.
The Promavia F.1300 Jet Squalus, also known as Promavia Jet Squalus F1300, was a two-seat light jet trainer designed by Italian Stelio Frati and built by Promavia in Belgium with support from the Belgian government.
The Garrett F109 was a small turbofan engine developed for the Fairchild T-46 by Garrett AiResearch. With the United States Air Force's cancellation of the T-46 program in 1986, further development of the engine ceased, and with it the civil TFE109 version.
The Garrett TPF351 is a turboprop engine designed by Garrett Engine Division of AlliedSignal Aerospace Company. Initiated by Garrett in October 1987, the TPF351-20 engine was selected by Embraer to power the Embraer/FMA CBA 123 Vector, a high-speed commuter "pusher" aircraft. It was first tested on May 19, 1989 and then ground tested and flight tested on a Boeing 720 on July 9, 1990. The first prototype CBA 123 was tested on July 18, 1990, followed by a flight to the Farnborough Air Show in September of the same year. Both programs were cancelled in 1992, when the TPF351 was nine months from engine certification.
The Boeing KC-46 Pegasus is an American military aerial refueling and strategic military transport aircraft developed by Boeing from its 767 jet airliner. In February 2011, the tanker was selected by the United States Air Force (USAF) as the winner in the KC-X tanker competition to replace older Boeing KC-135 Stratotankers. The first aircraft was delivered to the Air Force in January 2019. The Air Force intends to procure 179 Pegasus aircraft by 2027.
The Boeing–Saab T-7 Red Hawk, initially known as the Boeing T-X, is an American/Swedish supersonic advanced jet trainer produced by Boeing with Saab. On 27 September 2018, the United States Air Force (USAF) picked it for the T-X program to replace the Northrop T-38 Talon as the service's advanced jet trainer.
