Pratt & Whitney has won $6.7 billion contract for F119 engine sustainment from US Air Force.
Work is expected to be completed by Dec. 31, 2025, the US department of defense said in a statement Thursday.
F119 is an afterburning turbofan engine developed by Pratt & Whitney for the Lockheed Martin F-22 Raptor advanced tactical fighter. Two Pratt & Whitney F119 engines power the U.S Air Force’s F-22 Raptor.
The engine delivers thrust in the 35,000 lbf (160 kN) class, and is designed for supersonic flight without the use of afterburner. The F119 derivative, the F135, produces 40,000 lbf (180 kN) of thrust for the Lockheed Martin F-35 Lightning II.
