F135 engine exceeds 12,000 engine test hours as Pratt & Whitney prepares to deliver first production engines

The Pratt & Whitney F135 engine has surpassed 12,000 engine test hours as part of the system development and demonstration (SDD) phase of the development program. This achievement, in addition to the 3,600 test hours accumulated during the F-35 concept demonstration program, puts F135 engine test hours at more than 15,600. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

"Pratt & Whitney is proud of the F135's performance in the successful ground and flight test programs," said Warren Boley, vice president, Pratt & Whitney F135 engine programs. "This successful testing demonstrates the dependability and reliability of Pratt & Whitney's F135 propulsion system and the maturity that comes with the first production engines that we will deliver later this year."

The F135 engine program remains on track to support overall F-35 development and transition to production. Pratt & Whitney is scheduled to deliver the first seven production F135 engines later this year. The F135 conventional take-off and landing (CTOL) engine and short take-off and vertical landing (STOVL) propulsion system continue to power the F-35 Lightning II flight test programs with 113 flights and more than 134 flight test hours.

Additionally, Pratt & Whitney 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 eight international partner countries. The F135 is derived from proven technology of the only operational fifth generation fighter engine, the Pratt & Whitney F119. It has been further enhanced with technologies developed in several Air Force and Navy technology programs.

The F135 is the only engine powering the F-35 Lightning II flight test program. The F135 propulsion system has proven it can meet diverse aircraft requirements, and the ground and flight test experience demonstrates the maturity and the associated reliability of the F135 engine for armed forces around the world.
