The Lockheed YF-22 was designed to compete in the USAF Advanced Tactical Fighter program to replace the F-15 Eagle. Two aircraft were built for the competition and it was a twin engined aircraft with internal weapons bay aimed to achieve low observability "stealth".  It was rather big and the first YF-22 flight was September 1990. Maximum speed was aimed at over MACH 2 but the main purpose of the demonstrator was to test its characteristics mainly from Edwards AFB in California. Lockheed won the ATF competition from its competitor the Northrop YF-23. The YF-22 was later developed into the production Lockheed F-22 Raptor fighter exclusively delivered to the USAF.
