YF-22

The Lockheed/Boeing/General Dynamics YF-22 was a single-seat, twin-engined prototype fighter aircraft designed for the United States Air Force (USAF). The YF-22 was a finalist in the USAF's Advanced Tactical Fighter competition; two prototypes were built. The YF-22 won the contest against the Northrop YF-23, and entered production as the Lockheed Martin F-22 Raptor. The YF-22 is aerodynamically similar to the F-22, but with differences in the position and design of the cockpit, tail fins and wings, and in internal structural layout.

In the 1980s, the USAF began looking for a replacement for its fighter aircraft, especially to counter the advanced Su-27 and MiG-29. A number of companies, divided into two teams, submitted their proposals. Northrop and McDonnell Douglas submitted the YF-23. Lockheed, Boeing and General Dynamics proposed and built the YF-22, which, although marginally slower and having a larger radar cross-section, was more agile than the YF-23. Primarily for this reason, it was picked by the Air Force as the winner of the ATF in April 1991.
