100px|The two Northrop YF-23s
The Northrop YF-23 was a single-seat, twin-engine fighter aircraft
designed for the United States Air Force (USAF). In the 1980s, the USAF
began looking for a replacement for its fighter aircraft, especially to
counter the USSR's advanced Su-27 and MiG-29. Several companies
submitted design proposals; the USAF selected proposals from Northrop
and Lockheed. Northrop teamed 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 the
competition. After a four-year development and evaluation process, the
YF-22 was announced the winner in 1991 and entered production as the
Lockheed Martin F-22 Raptor. The U.S. Navy considered using one of the
ATF aircraft types to replace the F-14, but later canceled these plans.
The two YF-23 prototypes were on exhibit in museums as of 2009.
