Pratt & Whitney F135 Propulsion System Achieves Successful First Navy Variant F-35C Flight, Installation of First Production F135

EAST HARTFORD, Conn., June 23 /PRNewswire-FirstCall/ -- The Pratt & Whitney F135 propulsion system celebrated two major program milestones recently, with the successful maiden flight of the Lockheed Martin Navy variant F-35C Lightning II, powered by a production configuration F135 engine, as well as installation of the first production F135 engine into a production F-35 aircraft. Pratt & Whitney is a United Technologies Corp. (NYSE: UTX) company.

"It has been a tremendous year for the F135 engine as it continues its steady progress through conclusion of development testing and validation, and into full production and sustainment," said Bennett Croswell, Vice President of F135 and F119 Engine Programs.

The first F-35C flight, which lasted 57 minutes, was flown by Lockheed Martin Test Pilot Jeff Knowles and powered by an Initial Service Release (ISR) / production configured F135 engine. The Pratt & Whitney F135 Conventional Takeoff and Landing (CTOL) / Carrier Variant (CV) engine received ISR certification from the U.S. Governments in February indicating that the engine, with more than 17,600 test hours, has met all the ISR requirements for safety, reliability, durability and performance, and that it is now cleared for use in the field..

"The fact that this first F-35C flight was powered by a Pratt & Whitney ISR F135 engine is a clear demonstration that this engine is ready for use by our servicemen and women today," Croswell said.

Another recent F135 milestone achieved was installation of the first production configuration F135 propulsion system into a production F-35 aircraft.

"This is an achievement we celebrate with our teammates at the F-35 Joint Program Office and Lockheed Martin," said Warren Boley, President of Pratt & Whitney Military Engines. "Every day, with every milestone, the F135 propulsion system continues to demonstrate an unprecedented level of performance, maturity and dependability, and this achievement puts us one step closer to placing this game-changing aircraft into the hands of the U.S. military as well as those of our international partners."

Pratt & Whitney, the only engine manufacturer producing fifth generation propulsion systems, has designed, developed and tested the F135 to deliver the most advanced fifth generation fighter engine for the U.S. Air Force, Marine Corps and Navy, as well as for eight international partner countries.  The F135 is derived from proven technology of the only operational fifth generation fighter engine, the Pratt & Whitney F119 that exclusively powers the F-22 with more than 300,000 engine hours.  It has been further enhanced with technologies developed in several Air Force and Navy technology demonstration programs.

The F135 propulsion system has proven through extensive ground and flight test experience that it can meet diverse aircraft requirements, for armed forces around the world. The Pratt & Whitney F135 engine continues to be the only engine powering the successful Lockheed Martin F-35 Flight Test Program.

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.

This press release contains forward-looking statements concerning future business opportunities and operational engine performance. Actual results may differ materially from those projected as a result of certain risks and uncertainties, including but not limited to changes in funding related to the F-35 aircraft and F135 engines, changes in government procurement priorities and practices or in the number of aircraft to be built; challenges in the design, development, production and support of advanced technologies; as well as other risks and uncertainties, including but not limited to those detailed from time to time in United Technologies Corp.'s Securities and Exchange Commission filings.
