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.
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 Raptor's supercruise capabilities are touted as a major performance advantage over other fighters, with supercruise being demonstrated exceeding Mach 1.5. [ 13 ] [ 2 ] Supercruise capability provides advantages for stealth aircraft because an afterburner plume reflects radar signals and creates a significant infrared signature . [ 14 ]
Maximum speed: Mach 2.2, 1,452 mph (1,262 kn; ... Lockheed Martin FB-22 – Proposed bomber aircraft for the U.S. Air Force derived from the F-22 Raptor;
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.
According to Lockheed Martin in 2004, the only fifth-generation jet fighter then in operational service was their own F-22 Raptor. [2] [40] Lockheed Martin uses "fifth-generation fighter" to describe the F-22 and F-35 fighters, with the definition including "advanced stealth", "extreme performance", "information fusion" and "advanced sustainment".
The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...
Plans called for MANTA technologies to be demonstrated on either an F-22 Raptor or F-15. An X-44 prototype would begin test flights by fiscal year 2007. NASA planners stated that developing technologies for the X-44 could have application to the F-22 and Joint Strike Fighter programs and commercial supersonic ventures. [2]
