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 ]
The engine delivers thrust in the 35,000 lbf (156 kN) class and was designed for sustained supersonic flight without afterburners, or supercruise. 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.
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.
The F-22 Raptor is the top US fighter, known for stealth, speed and agility. ... It was one of the first fighters designed with supercruise capability, allowing it to fly at supersonic speeds ...
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 overall test objective was to evaluate biofuel fuel blend suitability in the F-22. Testing consisted of air starts, operability, and performance at different speeds and altitudes throughout the flight envelope. The F-22 Raptor performed several maneuvers including a supercruise [note 2] at 40,000 ft. reaching speeds of Mach 1.5. [5]
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.
