Adaptive Cycle Engines

Outperform. Outpace.
Only Adaptive Cycle Engines.
A new era of combat propulsion is here. The 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 that address the challenges faced from increasing geopolitical threats.

Revolutionary capabilities to deter geopolitical threats
The adaptive cycle engine 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 adaptive cycle engines unlock opportunities for greater power projection, better warfighting posture, and superior operational effectiveness.

%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.

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.
