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 ...
Northrop team's YF-23 (above) and Lockheed team's YF-22 (below) flying in formation. The first YF-23 made its maiden flight on 27 August 1990 and the first YF-22 first flew on 29 September 1990. [53] Flight testing began afterwards at Edwards Air Force Base and added the second aircraft for each competitor in late October 1990. [54]
The Lockheed Martin/Boeing F-22 Raptor is an American twin-engine, all-weather, supersonic stealth fighter aircraft.As a product of the United States Air Force's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities.
Northrop teamed up with McDonnell Douglas to develop the YF-23, while Lockheed, Boeing, and General Dynamics developed the YF-22. The YF-23 was stealthier and faster, but less agile than its competitor. After a four-year development and evaluation process, the YF-22 team was announced as the winner in 1991 and developed the F-22 Raptor, which ...
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 ...
As a result, both the YF-22 and YF-23 had lower performance with the YF119s than with the YF120s. [N 1] [8] On 3 August 1991, Pratt & Whitney was awarded the EMD contract for ATF engine, while the Lockheed/Boeing/General Dynamics team won the contract for the ATF airframe.
Designations YF-110 and YF-112 through YF-116 were acquired (captured or purchased) foreign aircraft used for evaluation and aggressor training. Designations YF-117 and YF-118 were black projects , with the F-117 designation later becoming the official Tri-Service designation of the production variant of the former.
The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...
