The Lockheed F-22 Raptor is an American air superiority fighter with highly developed ground attack capabilities as well as electronic warfare and electronic watch. The F-22 was in April 1991 the winner of the competition announced by the USAAF for the Advanced Tactical Fighter, which dates back to 1981. It was then that a $ 12 billion program was launched and the construction of a highly maneuverable, indirectly controlled, Stealth fighter began.
