In the 1980s Pratt & Whitney, a unit of United Technologies Corp., developed the YF119 prototype engine to meet USAF and U.S. Navy requirements for the Advanced Tactical Fighter Demonstration/Validation program. In 1990 it flew in both the Lockheed-Boeing-General Dynamics YF-22 and the Northrop-McDonnell Douglas YF-23 prototype aircraft.

To reduce maintenance, Pratt & Whitney designed the engine to use 40 percent fewer parts when compared to the then-current operational engines. The YF119 engine allows supersonic flight of the aircraft without using the afterburner, resulting in fuel savings and increased combat radius and effectiveness. In April 1991 the USAF selected the F119 engine for the F-22, Advanced Tactical Fighter.
