The result of the USAF\u0027s Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22\u0027s airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems. \u00a0 \nThe aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Despite its protracted development and various operational issues, USAF officials consider the F-22 a critical component of the service\u0027s tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unprecedented air combat capabilities. \u00a0 \nFor details of development, history, and airforces using the Raptor, click here.
