F-22 Raptor is a stealth fighter made in the United States. The aircraft was originally planned to serve as an air superiority fighter for use against Soviet warplanes, but the aircraft also features equipment for ground attack, electronic warfare, and intelligence signals. The aircraft went through a long development period, a prototype version dubbed YF-22, three years before being officially worn under the F / A-22 name, and was finally given the F-22A when it officially began in December 2005. Lockheed Martin Aeronautics is a contractor the major responsible for producing most of the F-22 airframe, armament and assembly. Later its partner, Boeing Integrated Defense Systems produces wings, avionics equipment, and pilot training and maintenance.
