EAST HARTFORD, Conn., Feb. 21, 2013 /PRNewswire/ --Pratt & Whitney's F117
engine, the exclusive power for the Boeing C-17 Globemaster III airlifter,
recently exceeded 10 million engine flight hours. At the same time, the C-17
exceeded 2.5 million flight hours while supporting military and humanitarian
mission in support of U.S. and allied troops around the globe. Pratt & Whitney
is a United Technologies Corp. (NYSE: UTX) company.

"This milestone is a testament to the reliability of the F117 engine," said
Bev Deachin, vice president, Military Programs and Customer Support, Pratt &
Whitney. "The exceptional performance of our engines – in some of the
harshest conditions – has helped the C-17 Globemaster III save countless lives
in military, humanitarian and disaster relief missions around the world."

Since 2006, Pratt & Whitney's F117 engines have accumulated more than six
million flight hours in support of worldwide air mobility missions. To put
this in perspective, it took 13 years of operational service for the engine to
reach its first four million flight-hour milestone. This statistic reflects
the C-17's increased workload over the past several years.

At the same time that the F117 has achieved 10 million flight hours, the
company is also celebrating with Boeing 15 years of successful partnership on
the performance-based logistics contract for the C-17.

"Through Pratt & Whitney's ongoing investment in product improvements and
industry partnerships the engine continuously surpasses established goals of
time on-wing and support turnaround time," said Deachin. "The F117 engine can
remain on-wing for up to eight years between servicing visits, which lowers
maintenance costs and provides outstanding mission readiness for C-17

The C-17 Globemaster III – the world's premier heavy airlifter – is operated
by four F117 engines, each rated at 40,440 pounds of thrust, enabling the C-17
transport to carry a payload of 164,900 pounds and fly 2,400 nautical miles
without refueling.

The F117-PW-100 first entered service in 1993 and is a member of Pratt &
Whitney's PW2000 family of commercial engines. With more than 10 million hours
of proven military service and 50 million hours in commercial use, the
F117/PW2040 has consistently proven itself as a world-class dependable engine.

The significant maturity of the F117/PW2040 program and Pratt & Whitney's
continual investment in product improvements has resulted in world class
safety and reliability metrics for the F117. The engine is widely recognized
as the most efficient engine in its class at all available thrust levels.
Fleet reliability and durability compliment the engine's efficiency and offer
significant fuel burn advantages.

The U.S. Air Force – including active National Guard and Reserve units – has
taken delivery of 218 C-17s. Other customers include the United Kingdom's
Royal Air Force, the Qatar Emiri Air Force, the Canadian Air Force, the Royal
Australian Air Force, the 12-member Strategic Airlift Capability initiative of
NATO and Partnership for Peace nations, and the United Arab Emirates Air Force
