F119 Achieves Significant Milestone Powering the F-22; 200,000 Flight Hours Logged During Safest Engine Introduction in USAF History

SINGAPORE, Feb. 14, 2012 - SINGAPORE AIR SHOW - Pratt & Whitney's F119, the world's first fifth-generation engine and the predecessor to the F135, has surpassed the 200,000 flight hour milestone powering Lockheed Martin's F-22 Raptor. This milestone recognizes the F119 as a fully mature engine. In addition, the F119 has demonstrated the safest and most reliable introduction of a fighter engine in United States Air Force history. Pratt & Whitney is a United Technologies Corp. (NYSE: UTX) company.

"Pratt & Whitney is proud of the F119 program's achievement and safety record and looks forward to another 200,000 flight hours powering the F-22 Raptor," said Cliff Stone, director, F119 Program, Pratt & Whitney. "With the F119 leading the way, we are able to celebrate the many accomplishments of the F135 powering the F-35 today. The continued maturation of our technology is another testament to the team and product at Pratt & Whitney."

The progression from the F119 to the next generation F135 engine significantly decreases the operational risk of the single engine F-35 aircraft. The F135 is the only engine powering the F-35 aircraft and currently in production for customers worldwide.

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 building industries.
