Pratt & Whitney F119 twin-spool augmented turbofan family for the Lockheed Martin F-22 Raptor. The F119-PW-100 is the first operational fifth-generation fighter engine, in the 35,000-pound thrust class, with stealth technology, supercruise capability, and a two-dimensional vectoring nozzle that directs thrust up to 20 degrees; two engines power each F-22. The F119 is the documented technology predecessor of the F135 family, with exact variants and installations modeled separately.
