Pratt and Whitney Engines, part of United Technologies Corp. (UTC), is awarded a contract modification, worth around $762.5 million, for the production and delivery of 58 F135 turbofan engines powering F-35 Lightning II fighter aircraft.
The modification exercises options for the Lot 14 production and delivery of 48 F135-PW-100 propulsion systems for the U.S. Air Force F-35A conventional takeoff and landing (CTOL) jets and 10 F135-PW-600 propulsion systems for the Marine Corps F-35B Short Take-Off and Vertical Landing (STOVL) jets. The Naval Air Systems Command (NAVAIR), Patuxent River, Maryland, is the contracting activity.
Work will be performed in East Hartford, Connecticut (85.3%); Indianapolis, Indiana (11.8%); and Bristol, United Kingdom (2.9%), and is expected to be completed in April 2022.
The Pratt & Whitney F135 is an afterburning turbofan developed for the Lockheed Martin F-35 Lightning II, a single-engine strike fighter.
The F135 family has several distinct variants; a conventional, forward thrust variant – F135-PW-100 – and a multi-cycle Short Take-Off Vertical Landing STOVL variant – F135-PW-600 – that includes a forward lift fan. The first production engines were delivered in 2009.
Developed from the Pratt & Whitney F119 engine used on the F-22 Raptor, the F135 produces around 40,000 lbf of thrust. The F135 competed with the General Electric/Rolls-Royce F136 to power the F-35.
