XA100
Adaptive Cycle Engine
Outperform. Outpace.
Only XA100.
A new era of combat propulsion is here. The XA100 adaptive cycle engine — designed, built, and tested through the U.S. Air Force's Adaptive Engine Transition Program (AETP) — defines a revolutionary jump in propulsion capabilities this decade that address the challenges faced from increasing geopolitical threats.
Revolutionary capabilities to deter geopolitical threats
A new era of combat propulsion is here. The XA100 adaptive cycle engine – designed, built, and tested through the U.S. Air Force's Adaptive Engine Transition Program (AETP) – defines a revolutionary jump in propulsion capabilities this decade which address the challenges faced from increasing geopolitical threats.
This XA100 is the only engine that allows U.S. warfighters to go further, go faster and fight harder against near-peer adversaries to satisfy the true needs of the U.S. and its Allies for strategic deterrence, today and tomorrow. The technologies developed for the XA100 unlock opportunities for greater power projection, better warfighting posture, and superior operational effectiveness of the F-35 fighter fleet while also creating capacity for near- and long-term growth of the platform.

%More range
Adaptive engine
The adaptive cycle engine provides a high-thrust mode for maximum power and a high-efficiency mode to extend mission range. Automatically alternating between these modes dramatically transforms mission capability and enables unrestricted operations.

%Thermal management
Third stream advantage
This advanced capability provides an extra source of cooled air to improve propulsion and fuel efficiency. Most importantly, it enables a step change in power and thermal management capability that will be required for next-generation mission systems.

%More acceleration
Advanced materials and components
The use of new, lighter-weight and more durable materials along with advanced additive manufacturing methods allows the engine to operate beyond previous-generation engine limits for more survivability. These new materials and methods also improve reliability and serviceability of the engine.
Congress renews support
for adaptive engine technology
"We appreciate the Senate Appropriations Committee decision to provide funds for next-generation propulsion programs, which will help provide our military pilots with cutting-edge capabilities needed in the face of today’s growing geopolitical threats. For over 100 years, GE Aerospace has helped ensure U.S. military aviation superiority, and with support in both the Senate and House, our XA100 engine stands ready to continue that legacy for decades to come."
