The Lockheed Martin/Boeing F-22 Raptor is an American twin-engine, all-weather, supersonic stealth fighter aircraft.As a product of the United States Air Force's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities.
Qualitative variation in Cd factor (drag coefficient) with Mach number (speed) for aircraft; supercruising above Mach 2 is efficient.The United States Air Force set supercruise as a core requirement for the Advanced Tactical Fighter program, [12] which resulted in the F-22 Raptor.
Delivering almost 22% more thrust with 40% fewer parts than its F100 predecessor, the F119 allows the F-22 to achieve supercruise speeds of up to Mach 1.8. [ 1 ] [ 2 ] The F119's nozzles incorporate thrust vectoring that enable them to direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability.
The F-22 is considered the top US air superiority fighter, known for stealth, speed, and agility. F-22 pilot Maj. Samuel Larson captivates audiences with daring displays in the fifth-gen fighter.
Flight testing for the F-22 continued until 2005, and on 15 December 2005 the USAF announced that the Raptor had reached its initial operational capability (IOC); with the collapse of the Soviet Union and the Department of Defense focused on counterinsurgency at that time, F-22 production only reached 195 aircraft and ended in 2011.

In the 1950s two turboprop tailsitter fighter prototypes were designed for the US Navy, the Convair XFY "Pogo" (610 mph (980 km/h)) and the Lockheed XFV (578 mph (930 km/h)), but both had less powerful engines than intended [21] [22] and conflicting demands of vertical and horizontal flight further compromised flight speeds [23] so they never ...
F-22 Raptor, the first U.S. operational supermaneuverable fighter aircraft.It has thrust vectoring and a thrust-to-weight ratio of 1.26 at 50% fuel.. Traditional aircraft maneuvering is accomplished by altering the flow of air passing over the control surfaces of the aircraft—the ailerons, elevators, flaps, air brakes and rudder.
