Lockheed Martin F

The Lockheed Martin F-22 Raptor is a fifth-generation single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF).

In 1981 the U.S. Air Force developed a requirement for an Advanced Tactical Fighter (ATF) as a new air superiority fighter to lớn replace the F-15 Eagle & F-16 Fighting Falcon.

The prototype aircraft (YF-22 & YF-23) both completed their first flights in late 1990. Ultimately the YF-22 was selected as best of the two và the engineering và manufacturing development effort began in 1991 with development contracts to Lockheed/Boeing (airframe) & Pratt và Whitney (engines).

After the flight kiểm tra demonstration & validation of the prototypes, in April of 1991, Secretary of the USAF Donald Rice announced the YF-22 as the winner of the ATF competition.

The F-22 Raptor is the Air Force"s newest fighter aircraft.

Its combination of stealth, supercruise, maneuverability, & integrated avionics, coupled with improved supportability, represents an exponential leap in warfighting capabilities.

The Raptor performs both air-to-air & air-to-ground missions. Significant advances in cockpit design and sensor fusion improve the pilot"s situational awareness. In the air-to-air configuration the Raptor carries six AIM-120 AMRAAMs and two AIM-9 Sidewinders.

The F-22 brings stealth into the day, enabling it not only to lớn protect itself but other assets. The F-22 engines produce more thrust than any current fighter engine.

The combination of sleek aerodynamic design and increased thrust allows the F-22 khổng lồ cruise at supersonic airspeeds (greater than 1.5 Mach) without using afterburner -- a characteristic known as supercruise.

The aircraft designation was the F/A-22 for a short time before being renamed F-22A in December 2005.
