The Pratt & Whitney F119 (company designation PW5000[1]) is an afterburning turbofan engine developed by Pratt & Whitney for the Lockheed Martin F-22 Raptor advanced tactical fighter.

The engine delivers thrust in the 35,000 lbf (160 kN) class, and is designed for supersonic flight without the use of afterburner (supercruise). Delivering almost 22% more thrust with 40% fewer parts than conventional, fourth-generation military aircraft engine models, the F119 allows sustained supercruise speeds of up to Mach 1.72.[2] The F119's nozzles incorporate thrust vectoring technology. These nozzles direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability.

The F119 derivative, the F135, produces 40,000 lbf (180 kN) of thrust[3] for the F-35 Lightning II.

History[edit]

In 2013 Pratt assisted the F119 Heavy Maintenance Center (HMC) at Tinker Air Force Base, Oklahoma in the first depot overhaul of a F119 engine.[4]
