Pratt & Whitney, a division of United Technologies Corp. (NYSE: UTX), has announced that its F119 engine, which powers Lockheed Martin´s F-22 Raptor, has surpassed 500,000 engine flight hours, the company said.
This marks a major milestone for the world´s first fifth-generation engine and the predecessor to the F-35 Lightning II´s propulsion system, the F135.
While the final production F119 engine was delivered in January 2013, Pratt & Whitney anticipates a 30- to 40-year sustainment period to keep the F-22 Raptor flying.
Two F119 engines power the F-22 Raptor, delivering unparalleled aircraft maneuverability and operational capability. The F119 features a combination of stealth technologies and a unique thrust-vectoring nozzle that allows unprecedented speed, agility, precision and situational awareness. Additionally, the F-22´s ability to operate at supersonic speeds without afterburner, known as supercruising, gives the aircraft exceptional combat performance without compromising mission range.
There are nearly 200 F119-powered F-22 Raptors currently in service with the US Air Force, operating from Joint Base Langley-Eustis, Virginia; Edwards AFB, California; Nellis AFB, Nevada; Tyndall AFB, Florida; Joint Base Pearl Harbor–Hickam, Hawaii; and Joint Base Elmendorf-Richardson, Alaska. Since entering operation in December 2005, the F119 propulsion system has demonstrated an exceptional track record in terms of safety, reliability and performance over the course of more than 200,000 flights.
