.The Pratt & Whitney F119 twin-spool augmented turbofan engine is one of the most
advanced fighter engines ever produced. The engine (used on the F-22 Raptor) combines
stealth technologies and vectored thrust with high
thrust-to-weight performance to provide better
maneuverability and survivability. The F119 is the predecessor to the F135,
which powers all three variants of the F-35 Lightning II.
The F119-PW-100 is equipped with a number of advanced technologies for operational performance and reliability.
The three-stage fan is powered by a single-stage low-pressure turbine. The counterrotating core of the F119 has
an aerodynamically efficient six-stage compressor which is driven by a single-stage high-pressure turbine.
It features single-crystal superalloy blades and advanced cooling technologies. The robust high-pressure
compressor features advanced airfoil aerodynamics and integrally bladed rotor disks for enhanced durability.
Supercruise (the ability to operate at supersonic speed without afterburning) gives the
F-22 Raptor exceptional combat performance without compromising
mission range.
The F-22 Raptor program is the next generation air superiority fighter. The F-22 will penetrate enemy airspace and achieve first-look, first-kill capability against multiple targets. The aircraft has unprecedented survivability and lethality.
On the F-22 Raptor, nozzle position management is integrated with the flight control system and automatically regulated by the Full-Authority Digital Engine Control (FADEC) system. The FADEC also monitors hundreds of other engine operating parameters.
On April 23, 1991, the F119 was selected to power the F-22 Raptor with ground testing commencing in late 1992.
The F119 was selected over General Electric's
YF120 variable cycle turbofan engine.
In September 1997, the F-22 made its first flight and, in December 2000, the first production engine was delivered.
On December 15, 2005, the U.S. Air Force announced that the F-22 Raptor was combat-ready,
thus achieving Initial Operating Capability (IOC). On December 12, 2007, the F-22 achieved Full Operational Capability (FOC).
In February 2012, the F119 surpassed the 200,000 flight hour milestone.
By January 2013, F119 engines had accumulated more than 250,000 flight hours.
On January 17, 2013, Pratt & Whitney Military Engines delivered the 507th and final F119 production engine.
In September 2014, the F119 powered the F-22's first combat mission.
In June 2017, the F119 surpassed 500,000 engine flight hours.
The F119 Heavy Maintenance Center (HMC) at Tinker Air Force Base in Oklahoma City, Oklahoma completed the first depot overhaul of an F119 engine
in March 2013.
