EAST HARTFORD, Conn., May 2, 2012 /PRNewswire/ --Pratt & Whitney has
successfully delivered the 50th production F135 engine – powering Lockheed
Martin's fifth-generation F-35 Lightning II – to the U.S. Department of
Defense. Pratt & Whitney is a United Technologies Corp. (NYSE: UTX) company.

The 50^th engine is scheduled to be installed in a F-35C Carrier Variant (CV)
for the United States Navy. The F-35C aircraft will be delivered toEglin Air
Force Base this summer for Navy pilot training.

"Delivery of the 50^th production F135 engine is a significant milestone for
the program," said Chris Flynn, vice president, F135/F119 Engine Programs,
Pratt & Whitney. "We are proud of the progress made on the most advanced
fifth-generation fighter engine in the world. We will continue to work
diligently toward production and testing benchmarks while meeting our cost
objectives."

Pratt & Whitney remains committed to increasing production levels while
decreasing costs. To date, Pratt & Whitney and its suppliers have been able
to reduce the cost by more than 25 percent on the CV/Conventional Takeoff and
Landing (CTOL) engine, compared to the original test engines. Engine
production output in 2012 is expected to double from 2011, as was demonstrated
from 2010 to 2011.

The F-35 program includes three variants to meet the unique needs of the U.S.
armed forces and the international participants in the program: the CV, the
CTOL and the Short Takeoff and Vertical Landing (STOVL). To date, the F135
propulsion system has powered more than 330 vertical landings, 2,000 test
flights producing more than 3,000 flight hours. Pratt & Whitney has delivered
30 CTOL/CV and 20 STOVL engines and related propulsion system hardware. The
success of the F135 engine program validates the reliability, safety and
performance of the engine.

Included in the 50 deliveries was the last deliverable hardware required for
the third lot of Low Rate Initial Production (LRIP) engines. Pratt & Whitney
is now delivering to the fourth lot of LRIP contract requirements which are
scheduled to be completed by the end of 2012.

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. 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

business opportunities. Actual results may differ materially from those
projected as a result of certain risks and uncertainties, including but not
limited to changes in the U.S. Government funding related to the F-35 and F135
