Pratt & Whitney Celebrates 40 Years of F100 Engine Power

FARNBOROUGH AIR SHOW, Tuesday, July 10, 2012

Pratt & Whitney celebrates 40 years of F100 propulsion, marking the development and delivery of its first F100 engines to support the F-15’s first flight on July 27, 1972. Today, the F100 engine powers the F-15, F-16 and X-47B Unmanned Combat Air System (UCAS), with an expanding F100 family of variants. Twenty-four customers worldwide have selected the F100 to power their F-15 and F-16 fighter jets over the past 40 years. Pratt & Whitney is a United Technologies Corp. (NYSE:UTX) company.

Pratt & Whitney’s F100 engine is one of the most successful fighter engines in history. The combat-proven engine has more than 27 million engine flying hours of experience. Pratt & Whitney has built more than 7,200 F100 engines for 23 countries around the world.

“For 40 years, the F100 engine has provided air forces around the world with superior performance and modern propulsion capabilities,” said Bev Deachin, vice president, Pratt & Whitney Military Programs & Customer Support. “We look forward to continuing to provide our customers with the world-class safety and reliability the industry has enjoyed from the F100.”

The newest member of the F100 engine family, the F100-PW-229 Engine Enhancement Package (EEP), offers significant safety benefits, and increases the engine depot inspection interval from 4,300 to 6,000 total accumulated cycles (TAC). This increase is equivalent to extending the depot interval from seven years to ten years. In addition, the EEP provides a 30 percent life cycle cost reduction over the life of an F100-PW-229 engine.
