XA100 Adaptive Cycle Engine

Outperform. Outpace. Only XA100.

The only option ready to deliver for the U.S. and its Allies.

XA100 Adaptive cycle engine

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.

Ready to meet warfighter needs

More Range

Adaptive engine

The adaptive cycle engine provides a high thrust mode for maximum power and 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 propulsive 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 allow 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.

Why the time is now


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."
