Pratt & Whitney’s F119 Engine Surpasses 100,000 Operational Flight Hours

EAST HARTFORD, Conn.– Pratt & Whitney’s F119 engine, which powers the Lockheed Martin F-22 Raptor, has surpassed 100,000 operational flight hours of service for the U.S. Air Force. The accomplishment marks a significant milestone for the only operational fifth generation fighter engine in service today and demonstrates the maturity of the propulsion system. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

“With more than 100,000 operational flight hours, the F119 engine is truly a proven and mature fifth generation engine,” said Tyler Evans, F119 program director. “We are proud of our ongoing partnership with the U.S. Air Force and the fact that we are delivering on our commitments to our valued customer. The flight experience we have on the F119 will deliver built-in maturity for the F135 engine, the lead propulsion system on the F-35 Lightning II.”

The F135 propulsion system, a derivative of the F119 engine, 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.

“The core of the F135 engine is being matured and proven in the twin engine F-22,” Evans said. “And with 100,000 flying hours we are able to incorporate the maturity and learning from the F119 core into the F135 propulsion system for the single-engine F-35.”

Two F119 engines power the F-22 Raptor, delivering unparalleled aircraft maneuverability and unmatched operational performance and reliability. The F119 features an unrivaled combination of stealth technologies and vectored thrust with high thrust-to-weight performance. The F-22’s ability to operate supersonically without afterburner, known as supercruise, gives the F-22 exceptional combat performance without compromising mission range.

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, space propulsion systems and industrial gas turbines. United Technologies, based in Hartford, Conn., is a diversified company providing high technology products and services to the global aerospace and commercial building industries.
