Contact: Stephanie Duvall (860) 557-1382 stephanie.duvall@pw.utc.com Pratt & Whitney F135 -- The World's Most Powerful Fighter Engine
The Pratt & Whitney F135 propulsion system is the power of choice for a new advanced, single-engine tactical fighter, the F-35 Lightning II being developed by Lockheed Martin. The F-35 will have unique capabilities for land-based conventional take off and landing (CTOL), carrier-variant (CV), and short take off and vertical landing (STOVL). The same F135 engine will power all three variants. The F135 propulsion system has already proven that it can meet these diverse requirements as it was chosen by both Lockheed Martin and the Boeing Company as the exclusive power for all Concept Demonstration Aircraft (CDA) Joint Strike Fighter flights. The engines accumulated more than 3,600 ground test and nearly 200 flight test hours during the CDA phase of the JSF development program. System Development and Demonstration On October 26, 2001, Pratt & Whitney was awarded a ten year $4.8 billion (U.S.) contract for System Development and Demonstration (SDD). Under the SDD contract, Pratt & Whitney will develop the F135 propulsion system through flight clearance, flight test, and qualification for Low Rate Initial Production, which will begin in 2009. To date, Pratt & Whitney has delivered to ground test five CTOL/CV configuration and four STOVL configuration F135 engines. Combined, F135 ground test engines have accumulated more than 7,700 hours of SDD testing, which includes 1,000 hours of power lift testing. Pratt & Whitney will add three additional ground test engines to the test cycle as part of the SDD program. In August 2005, Pratt & Whitney was awarded a contract modification worth up to $968 million to align the F135 engine System Development and Demonstration program with the F-35 Joint Strike Fighter schedule plan. Powering the F-35's First Flight In March 2005, the Pratt & Whitney F135 System Development and Demonstration program successfully passed a post test Critical Design Review lead by the U.S.
