F119 Engine: The Heart of the F-22 Raptor's Advanced Capabilities

The F119 engine developed by Pratt & Whitney significantly enhanced the F-22 Raptor, enabling it to perform supercruise — flying supersonically without the aid of afterburners. This advanced engine was selected over General Electric's YF120 to power what would become a cornerstone of US air superiority, the F-22 Raptor.

The F119 engine was designed to sustain supersonic cruise without afterburners while maintaining high thrust and low fuel consumption.

What has been confirmed

The F119 engine was officially confirmed to enable supersonic cruise, reduce infrared signature, and provide high thrust with improved fuel economy. These capabilities were critical to the operational success of the F-22. The F-35, a subsequent aircraft, utilizes a derivative of the F119 engine. Pratt & Whitney and GE Aerospace are confirmed to be developing adaptive cycle engines for next-generation aircraft.
