United Arab Emirates Air Force Receives First Pratt & Whitney-powered C-17 Aircraft

PARIS AIR SHOW, Monday, June 20, 2011

The United Arab Emirates Air Force recently received its first C-17 Globemaster III, powered exclusively by four Pratt & Whitney F117 engines. The UAE Air Force is slated to receive a total of six C-17s by 2012. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

The UAE Air Force received its first new C-17 in a ceremony at Boeing's final assembly site in Long Beach, California in mid May. "We are proud to power the C-17s being purchased by the UAE," said Bev Deachin, vice president, military programs and customer support at Pratt & Whitney. "We are confident the UAE Air Force will benefit from the outstanding airlift capability of the C-17."

The C-17 Globemaster III – the world's premier heavy airlifter – is powered by four F117 engines. With more than 8 million hours of proven military service and 45 million hours in commercial use, the F117/PW2037 has consistently proven itself as a world-class dependable engine. Pratt & Whitney's ongoing investment in product improvements has enabled the engine to continuously surpass established goals for time on wing, in-flight shut downs and support turnaround time.

In addition to the UAE Air Force, other international customers include the United Kingdom's Royal Air Force, the Qatar Emiri Air Force, the Canadian Forces Air Command, the Royal Australian Air Force, and the 12-member Strategic Airlift Capability initiative of NATO and Partnership for Peace nations.
