Pratt & Whitney Delivers 800th F117 Engine to U.S. Air Force

PARIS AIR SHOW, PARIS, France, June 18, 2007 - Pratt & Whitney, a United Technologies Corp. (NYSE: UTX) company, recently delivered the 800th F117 engine to the United States Air Force. The F117 engines power 100 percent of the the C-17 Globemaster III transport aircraft worldwide.

Four F117 engines, rated at 40,440 pounds of thrust, enable the C-17 transport to carry a payload of 160,600 pounds, take off from a 7,600-foot airfield, and fly 2,400 nautical miles without refueling.

“Pratt & Whitney is proud to deliver the 800th engine as we continue to expand our customer base across the globe,” says Bev Deachin, mobility and surveillance systems director, Pratt & Whitney Military Engines. “This milestone is yet another testament to the impressive dependability and reliability of Pratt & Whitney’s F117 engine.”

The F117-PW-100 is a derivative of Pratt & Whitney’s PW2000 commercial engine powering the Boeing 757. The F117 has consistently proven itself as a world-class reliable engine. Through Pratt & Whitney’s ongoing investment in product improvements, the engine continuously surpasses established goals for time on wing, in-flight shut downs and support turnaround time. The F117 fleet benefits from more than 4.7 million engine flight hours accumulated by the United States Air Force, United Kingdom’s Royal Air Force and users around the world.

Pratt & Whitney military engines include the F100 that powers the F-16 and F-15, the F135 for the F-35 Lightning II; F119 for the F-22 Raptor; F117 for the C-17 Globemaster III; J52 for the EA-6B Prowler; TF33 powering AWACS, Joint STARS, B-52, and KC-135 aircraft; TF30 for the F-111; PT6 for T-6A and UH-1N aircraft; and JT15 for the T-1A trainer.
