A YF-22 in the foreground with a YF-23 in the background The two contractor teams submitted evaluation results and their PSC proposals for full-scale development in December 1990, [ 57 ] and on 23 April 1991, Donald Rice , the Secretary of the Air Force announced that the YF-22 team was the winner. [ 71 ]
The YF-22 team won the contest against the YF-23 team for full-scale development and the design was developed into the Lockheed Martin F-22. [N 1] The YF-22 has a similar aerodynamic layout and configuration as the F-22, but with notable differences in the overall shaping such as the position and design of the cockpit, tail fins and wings, and ...
The YF-22 and YF-23 in formation during flight testing in the early 1990s The squadron was first activated as the 6511th Test Squadron in March 1989 to conduct the Advanced Tactical Fighter program. It began flying the Northrop YF-23 on 27 August and the Lockheed YF-22 on 29 September 1990, flying both through December 1990, though the ...

In order to fly the F-22, Larson said he had to go through basic pilot training, consisting of 55 weeks of flying in trainer aircraft like the T-6 Texan II and a T-38 Talon.
The Advanced Tactical Fighter (ATF) was a program undertaken by the United States Air Force to develop a next-generation air superiority fighter to replace the F-15 Eagle in order to counter emerging worldwide threats in the 1980s, including Soviet Sukhoi Su-27 and Mikoyan MiG-29 fighters under development, Beriev A-50 airborne warning and control systems (AWACS), and increasingly ...
Lockheed YF-94 (S/N 48-373). This was the second aircraft built (from TF-80C) On 16 April 1949, the first YF-94 prototype performed its maiden flight. [6] To accelerate development, these early test aircraft were converted from existing T-33s; they maintained roughly 75% commonality in terms of components with those used in the earlier F-80 and T-33As.
The YF120 had different nozzle designs for the YF-22 and YF-23 technology demonstrator prototypes tailored to the specific airframe. The YF120 on the YF-22, registration number N22YF, was equipped with thrust vectoring nozzles. The engine for the YF-22 featured a two-dimensional thrust vectoring nozzle that could vector in the pitch direction ...
