Proven power for the F-22 Raptor
Pratt & Whitney’s F119 turbofan engine is the world’s first fifth-generation fighter engine. The F119 combines stealth technologies and
vectored thrust performance to provide unprecedented maneuverability and survivability with a high thrust-to-weight ratio. The ability
to operate supersonically without afterburner— supercruise—gives the F-22 exceptional combat performance without compromising
mission range.
