PARIS AIR SHOW, Monday, June 20, 2011

Pratt & Whitney has delivered the first F135 spare engine to the U.S. Air Force at Eglin Air Force Base in Florida to support F-35 Lightning II training operations to begin this summer. Eglin's 33rd Fighter Wing is a joint unit with Air Force, Navy and Marine squadrons that will conduct F-35 training for their respective services as well as the eight F-35 program international partners. Lockheed Martin is scheduled to deliver the first F-35A aircraft to Eglin AFB in the coming weeks. Pratt & Whitney is a United Technologies Corp. (NYSE: UTX) company.

"Delivery of the first F135 engine to Eglin in support of training operations is a significant milestone for the F-35 program. Pratt & Whitney looks forward to supporting the U.S. Services as they begin official training of this remarkable fifth generation multi-role fighter," said Chris Flynn, vice president, F135/F119 Engine Programs. "We have completed the delivery of the first two production lots of engines and have started engine deliveries in the third production lot. In addition, we also recently signed a firm fixed-price contract for the fourth lot of production engines that meets the affordability objectives of our customer."

Pratt & Whitney has designed, developed and tested the F135 to deliver the most advanced fifth-generation fighter engine for the United States and its allies around the world. The F135 is the only engine powering the F-35 Lightning II flight test program today with nearly 1,000 flights, 1,450 flight hours and more than 110 flawless vertical landings. We've achieved these milestones while maintaining a flight test readiness level of 98 percent.
