The Lockheed Boeing General Dynamics YF-22 was a single-seat, twin-engined prototype fighter aircraft designed for the SAF. 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 internal structural layout.
The aircraft on display at the museum is the first of two YF-22s built (S/N 87-0700, N22YF), and was powered by the GE YF120 engines. It was initially delivered on 29 August 1990 and made its first flight on 29 September 1990.
