Jet Engine major Pratt & Whitney has delivered the 500th F119 engine, which powers the Lockheed Martin F-22 Raptor, to the U.S. Air Force.
This delivery is accompanied by another significant milestone for the F119 program – more than 20 years of simulated operational service through Accelerated Mission Tests (AMTs), an achievement that further demonstrates the maturity and dependability of the world's first fifth-generation fighter engine.
An accelerated mission test compresses many years of operational service into a short duration test, which allows for a robust evaluation of engine durability. During the most recent period of testing, an F119 production engine ran for nearly 570 hours, accumulating more than 2,000 cycles or approximately four years of service.
Combined with previous testing, this engine has now surpassed 20 years of simulated operational service. Pratt & Whitney F119 engines have accumulated over 230,000 of actual operational flight hours powering the F-22 fleet.
With production of the F119 engine nearly complete, Pratt & Whitney continues to deliver F135 engines from the fifth generation production line, with 70 production engines delivered to date.
The F135 engine shares similar core components with the F119 engine and powers the F-35 Lightning II fighter aircraft. The F135 engine has powered more than 2,300 flights, with over 3,700 flight hours and 336 vertical landings.
