The Lockheed Martin F-22 Raptor is an American single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). As the result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also has ground attack, electronic warfare, and signals intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted the final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.

The F-22 first flew in 1997 and 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 operational difficulties, USAF considers the F-22 a critical component of its tactical airpower. The fighter's combination of stealth, aerodynamic performance, and mission systems enable unprecedented air combat capabilities.
The USAF had originally planned to buy a total of 750 ATFs. In 2009, the program was cut to 187 operational aircraft due to high costs, a lack of air-to-air missions due to the focus on counterinsurgency operations at the time of production, a ban on exports, and the development of the more affordable and versatile F-35, with the last F-22 delivered in 2012.
In 1981, the U.S. Air Force identified a requirement for an Advanced Tactical Fighter (ATF) to replace the F-15 Eagle and F-16 Fighting Falcon. Code-named "Senior Sky", this air-superiority fighter program was influenced by emerging worldwide threats, including new developments in Soviet air defense systems and the proliferation of the Sukhoi Su-27 "Flanker"- and Mikoyan MiG-29 "Fulcrum"-class of fighter aircraft. It would take advantage of the new technologies in fighter design on the horizon, including composite materials, lightweight alloys, advanced flight control systems and avionics, more powerful propulsion systems, and most importantly, stealth technology. In 1983, the ATF concept development team became the System Program Office (SPO) and managed the program at Wright-Patterson Air Force Base. The demonstration and validation (Dem/Val) request for proposals (RFP) was issued in September 1985, with requirements placing a strong emphasis on stealth and supercruise. Owing to the immense investments required to develop the technology needed to achieve performance goals, teaming between companies was encouraged. Of the seven bidding companies, Lockheed and Northrop were selected on 31 October 1986...
