EAST HARTFORD, CT- Pratt & Whitney has delivered the 400th F119 engine, which powers the Lockheed Martin F-22 Raptor, to the U.S. Air Force. This milestone delivery marks a significant accomplishment for the only operational fifth generation fighter engine in service today and demonstrates the maturity of this highly advanced propulsion system.


The maturity in both production and flight experience of the F119 engine continues to provide a heritage of proven performance for F135 engine because the F135 is a derivative of the F119 engine and uses a common core. The F135 engine is the lead propulsion system on the F-35 Lightning II, is the only engine currently powering the F-35 Joint Strike Fighter. The common technology derived from the proven F119 offers a significant advantage to the F135 with respect to maturity and single engine safety.


Two F119 engines power the F-22 Raptor, delivering unparalleled aircraft maneuverability and unmatched operational performance and reliability. The F119 features a combination of stealth technologies and vectored thrust with high thrust-to-weight performance. The F-22's ability to operate at supersonic speeds without afterburner, known as supercruising, gives the F-22 combat performance without compromising mission range.
