October 18, 2007 (by Asif Shamim) - The Pratt & Whitney F119 engine, which is the exclusive power source for the USAF F-22 Raptor, exceeded 50,000 production flight hours in October, another major milestone for the engine program.
A Pratt and Whitney F119 engine runs in full afterburner during an engine test in the "hush house" at Tyndall AFB.
Powered by two F119s, the F-22 is able to supercruise, or achieve supersonic speeds without the use of the afterburner.
The engine features a unique thrust-vectoring nozzle, allowing unprecedented speed, agility, precision and situational awareness combined with air-to-ground and air-to-air combat capabilities.
"This engine continues to establish benchmarks for fighter engine safety and reliability," said Chris Flynn, Pratt & Whitney F119 program director. "These standards demonstrate the robust capability of Pratt & Whitney’s latest operational engine and we are proud of this important accomplishment."
The F-22 team was awarded the 2006 Collier Trophy, one of aviations top honors, and the F119 team participated as the propulsion provider.
A derivative of the F119, the F135 engine, powers the new F-35 Lightning II, which completed its first flight in December 2006, and continues to power the F-35 flight test program.
F119-powered F-22 Raptors currently operate from Langley AFB
, Virginia; Edwards AFB, California; Nellis AFB, Nevada; Tyndall AFB, Florida; and Elmendorf AFB, Alaska, as of August 8, 2007.
