General Electric Bests Pratt & Whitney In $1.6B F-15ex Engine Competition


The U.S. Military stated today that General Electric’s F110-129 engines would continue to power the Boeing F-15EX Eagle II, granting the firm a $1.6 billion agreement.

The decision ended a dispute between Pratt & Whitney, which built F100 engines for the vintage F-15 Eagle and F-15E Strike Eagle, and General Electric, which built GE F110-129 engines for the initial batch of eight F-15EX planes.


Pratt & Whitney presented the F100-PW-229, the most recent variant of the F100, for the F-15EX engine contest. According to the Pentagon’s contract announcement, no further proposals were received.

The new deal includes engines for the remaining half and even beyond, with up to 329 engines for the twin-engine fighter potentially available.

“The United States Air Force is pleased to work with General Electric as the engine manufacturer for America’s newest, most advanced F-15 aircraft,” said Brig. Gen. Dale R. White, the service’s program executive for fighters and advanced aircraft. “Not only will it cut maintenance costs and risk as it replaces our old F-15C/D aircraft, but it will also provide unique innovations to our present and future TACAIR (tactical air) inventory.”

The solid, fixed-price contract commits $137 million for 29 engines, which covers all 12 Lot 2 planes plus spares. The contract also contains seven more options that span the program’s lifetime.

The Air Force indicated in a press release those deliveries will begin in October 2023 and continue until June 2031.

A spokeswoman for Pratt & Whitney declined to say if the business would contest the award.

General Electric responded positively to today’s statement right away.

Shawn Warren, GE’s vice president and general manager of combat and trainer engines, said, “The F110 manufacturing line is operating now and ready to deliver on the US Air Force’s urgent and compelling demand for an F-15EX propulsion system.” “We’re satisfied with the engine’s performance on the two F-15EX test planes that flew today, and we’re looking forward to bringing that performance to the rest of the fleet.”
