GE Aerospace's XA100 Engine Testing Achieves New Milestone

November 14, 2023

EVENDALE, Ohio—November 14, 2023—GE Aerospace (NYSE: GE) announced today that its XA100 engine successfully completed additional testing, in coordination with the U.S. Air Force (USAF), after completing all Adaptive Engine Transition Program (AETP) testing last year. With continued positive testing results as well as Congressional support for advanced engine development, GE Aerospace is moving this cutting-edge technology closer to the hands of America’s warfighters, with learnings that could support the Next Generation Adaptive Propulsion (NGAP) program.  

Supported by over 400 engineers, the second XA100 engine underwent its third round of testing at GE Aerospace's Evendale, Ohio facility to validate minor design improvements informed by previous testing conducted in 2022; further solidify the engine's detailed design and digital models; and accelerate adaptive propulsion development and associated technologies for sixth-generation applications through scenario-specific testing.  

“Our XA100 engine, already the most advanced combat engine ever developed, is now one of our most tested prototypes,” said GE Aerospace Vice President and General Manager for Advanced Defense Products David Tweedie. “This third round of testing represents our commitment to go above and beyond to ensure our military is ready with the revolutionary capabilities they need, and we are pleased with the learnings it has provided for our work today and in the future.”  

GE Aerospace’s XA100 engines have now logged hundreds of hours of rigorous, system-level performance and operability testing, providing the company with unprecedented knowledge of the adaptive cycle engine architecture and the transformational capabilities it offers. The XA100 engine is estimated to provide pilots up to 25 percent greater fuel efficiency and 30 percent greater range to help the U.S. ensure its airpower advantage in contested environments. Additionally, the XA100 provides twice the thermal management capacity compared to current fighter engines, which enhances the capabilities of onboard electronics and sensors for this decade and beyond.    

"With a third round of testing, GE Aerospace has proven again our place as the industry leader in adaptive cycle engines,” said GE Aerospace’s Defense & Systems President and CEO Amy Gowder. "Recent Congressional support for advanced engine development in the defense appropriations bills will help continue our progress as we work to bring this revolutionary technology forward for U.S. warfighters."
