GE Military Engine Programs in the Midst of Historic Stretch

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.
