Testing on second XA100 adaptive cycle engine prototype begins
F110-powered F-15EX flight test campaign progresses
GE remains confident with two B-52 CERP options
GE’s partnership with the U.S. Air Force stretches back to the service branch’s creation in 1947. Nearly 75 years later, GE remains steadfast in its support of current Air Force programs and has a historically robust suite of technology ready to accelerate innovation and support the Air Force of the future.
XA100 Adaptive Cycle Engine
GE initiated testing on its second XA100 adaptive cycle engine as part of the U.S. Air Force’s Adaptive Engine Transition Program (AETP) on August 26, 2021. Engine prototypes assembled as part of AETP are designed to fit and integrate directly into the F-35.
“The U.S. Air Force and Congress have invested more than $4 billion in adaptive cycle engine development over the past 14 years to mature its associated technologies. We’re confident this phase of the program will significantly reduce risk and prepare GE for a low-risk engineering and manufacturing development program, consistent with Air Force objectives,” said David Tweedie, GE Edison Works’ General Manager for Advanced Combat Engines. “Getting our second prototype engine into the test cell means we’re one step closer to getting this transformational technology into the hands of the warfighter.”
Testing on the second XA100 will allow GE to continue gathering high-quality test data and further mature the engine’s advanced componentry and revolutionary three-stream design. Once first phase testing is complete in Evendale, GE plans to test the engine at the U.S. Air Force’s Arnold Engineering Development Complex (AEDC) to finish out all planned AETP testing activities.

F110 Engine for the F-15EX
Both F-15EX aircraft undergoing Operational Test and Evaluation (OT&E) out of Eglin Air Force Base rely on GE’s F110—the only certified and in-production engine that powers every Advanced F-15 in service today, including the F-15EX.
Just weeks after the second EX aircraft was delivered to Eglin, both OT&E jets participated in Northern Edge 21, the bi-annual joint training exercise in Alaska. Lt. Col. Weston Turner, director of the F-15 Division at the Air National Guard/Air Force Reserve Test Center, and an F-15EX test pilot who flew in the exercise, reported going “higher and faster than the F-15Cs due to the GE [F110]-129 motors.”
The first eight F-15EX will feature GE F110 power, and GE has submitted its proposal to power the remaining F-15EX fleet.

B-52 Commercial Engine Replacement Program
GE is offering two engines proven in the most demanding environments and operating conditions around the globe—the ever-reliable CF34-10 engine and the technologically advanced Passport engine. These two engines offer the lowest program risk, the highest mission readiness, and the lowest cost of operation for the U.S. Air Force.
GE is the only company to have been involved in re-engining U.S. Air Force aircraft three times over and the only company to have experience powering six strategic bombers.
The mainstay of the U.S. strategic nuclear fleet demands rugged, reliable, and commercially-proven equipment to continue to operate from a position of enduring strength for the foreseeable future. GE is the clear partner to ensure the B-52 is ready at all times for the most critical missions.
