Pratt & Whitney Awarded Production Contract for F135 Engines

EAST HARTFORD, Conn., August 27, 2007 – Pratt & Whitney, a United Technologies Corp. (NYSE:UTX) company, was awarded a $60 million production contract for F135 engines to power the F-35 Lightning II. This contract is for long lead-time material covering sixteen F135 engines supporting twelve production F-35 aircraft for Low Rate Initial Production 2 (LRIP 2). LRIP 2 includes six conventional take-off and landing (CTOL) engines, six short-takeoff/vertical-landing (STOVL) propulsion systems and two spares per variant.

“We are excited to continue production of CTOL engines and enter into production of the STOVL propulsion system,” said Bill Gostic, vice president, Pratt & Whitney F135 engine program. “This contract will allow us to provide LRIP 2 engines to support the F-35 schedule.”

This contract is one of a series of milestones for the F135 propulsion system. Pratt & Whitney’s F135 recently exceeded 8,300 system development and demonstration (SDD) ground test hours. The 8,300 SDD hours are in addition to the more than 3,600 hours accumulated during the concept demonstration phase of the F-35 program, reflecting the F135's maturity and reliability. The F135 powered the F-35 Lightning II’s first flight in December 2006, and continues to power the flight test program with 19 flight tests to date.

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 global aerospace and building industries.
