BACKGROUND F119
The F119 -- The World’s Most Advanced Fighter Engine

Pratt & Whitney’s advanced technology F119 turbofan engine powers the U.S. Air
Force’s 5th generation air dominance fighter, the F-22 Raptor. More than 260 F119
production engines have been delivered to the air force. The F-22 Raptor maintains a
record of no engine related incidents leading to the loss of aircraft. Keys to the Raptor’s
ability to achieve its objectives are the maturity, affordability, performance and
supportability of its Pratt & Whitney F119 twin-engine propulsion system.
Pratt & Whitney personnel and shop support are sustaining F119 engines in operation at
four U.S. Air Force Bases: Edwards AFB, California, Nellis AFB, Nevada, Tyndall AFB,
Florida and Langley AFB, Virginia. The F-22 achieved Initial Operational Capability
(IOC) on 15 December 2005 with F-22s assigned to the 1st Fighter Wing at Langley.
This declaration demonstrates that the F-22 has completed its development testing and is
ready for actual combat. Preparations to stand-up Raptor operations at Elmendorf AFB
in Alaska are well underway.
The F-22 is the only fighter in the world that can provide the air dominance necessary to
ensure freedom of maneuverability for U.S. and allied ground, air, and naval forces in
contingency and combat operations. The unique design of the F119 combines stealth
technologies and vectored thrust with high thrust-to-weight performance to provide the F-
22 unprecedented maneuverability and survivability. Supercruise, the ability to operate
supersonically without afterburning, gives the Raptor exceptional combat performance
without compromising mission range.
The F119 engine’s proven propulsion concepts, designs, software architectures and
manufacturing technologies have been incorporated into Pratt & Whitney’s F135 engine
for Lockheed Martin’s F-35 Lightning II, Joint Strike Fighter. Use of the common
engine core has saved the government millions of dollars in development costs;
additionally, advances made to the F135 engine will be transitioned back to the F119
engine program. This approach keeps both propulsion systems state-of-the-art, and
provides rugged and reliable performance for air force and allied combat units.
Supportability of the F119 powered F-22 Raptor is paramount to the success of the
program. The F-22 support concept is based upon long-term air force and industry
partnerships. Pratt & Whitney leads the prime contractors with the July 2004 opening of
the F119 Heavy Maintenance Center in partnership with the air force’s Oklahoma City
Air Logistics Center.
The F-22 Raptor’s unprecedented performance is garnering it prestigious industry
recognition. On June 8, 2007 the National Aeronautic Association awarded the esteemed
2006 Robert J. Collier Trophy to the Lockheed Martin F-22 Raptor team, including Pratt
& Whitney, Boeing, Northrop Grumman, Raytheon, and BAE Systems. The team was
chosen for excellence in the design, test, and operation of the F-22 Raptor throughout its
development, testing and manufacturing phases. Special recognition was given to the
fighter jet’s 2006 Operation Northern Edge exercises held in Alaska, a performance that
affirmed the Raptor as the most reliable, survivable and revolutionary fighter the world
has ever seen.
Pratt & Whitney military engines include the F100 that powers the F-16 and F-15, the
F135 for the F-35 Lightning II; F119 for the F-22 Raptor; F117 for the C-17 Globemaster
III; J52 for the EA-6B Prowler; TF33 powering AWACS, Joint STARS, B-52, and KC-
135 aircraft; TF30 for the F-111; PT6 for T-6A and UH-1N aircraft; and JT15 for the T-
1A trainer.
Pratt & Whitney is a world leader in the design, manufacture and service of aircraft
engines, space propulsion systems and industrial gas turbines. United Technologies,
based in Hartford, Conn., is a diversified company providing high technology products
and services to the global aerospace and commercial building industries.
