The F119-PW-100 turbofan engine with afterburner has been developed by the American company Pratt & Whitney, specially for the newest United States Air Force fighter jet; the 2-engine F-22A Raptor.
F119 is the most powerful operational engine ever, used on a fighter jet.
Each engine produces more than 35,000 pounds of thrust which gives the Raptor
more than 70,000 pounds of thrust. It can push the Raptor to supersonic
speeds of Mach 1.5 without using the afterburner. This feature is called
supercruise. The exact thrust is secret. In comparison, the current one-F-16
engine has a thrust of 15,000 lbs with a maximum of 25,000 lbs.
The F119 is fitted with 2-dim. Thrust Vector Control (TVC) which "helps" the aircraft's flight control system to pitch the aircraft. With his, the Raptor has superior maneuverability. The F-22 is also the world 's first operational fighter jet with TVC.
In comparison: the Russians are still in the test phase with TVC. The Europeans have also developed a TVC for the Eurofighter but has not yes been used. The F-22 is already in full production and will partially replace the USAF F-15C fleet.
