A First Look At The Next Generation

The revolutionary new GE Adaptive Cycle Engine (ACE) is the latest in a proud legacy of game-changing propulsion innovations from GE Aviation.


Dramatically Transforming Tomorrow's Missions

Developed under the U.S. Department of Defense’s Adaptive Versatile Engine Technology (ADVENT) and Adaptive Engine Technology Development (AETD) programs, the GE ACE is the only engine that combines outstanding fuel burn with increased, fighter-level thrust, enabling military aircraft to go greater distances and engage more targets.

Unlike traditional engines with fixed airflow, the GE ACE is a variable cycle engine that will automatically alternate between a high-thrust mode for maximum power and a high-efficiency mode for optimum fuel savings. And that means a whole new book of operational possibilities for the U.S. Air Force.

Further, Faster And With More Power Than Ever Before

Tomorrow’s missions will require aircraft to fly greater distances with unprecedented speed and power, and the GE ACE can answer the call.

Radical Energy

GE and the Air Force Research Lab have completed testing of the world's first three-stream adaptive cycle engine and are working to change the accepted limits of propulsion technology.

The Shape of Things to Come

GE is using 3D technology to develop complex components one layer at a time and open the creative canvas for engineers.

Innovative To The Core

By introducing rotating CMC parts into its hardest-working sections, the GE ACE can withstand higher temperatures than ever before.

An Incredible New Standard In Engine Performance

The revolutionary technologies inside the GE ACE will work together to deliver next generation performance benefits.

50% improvement in loiter time to persist longer in areas of interest with reduced risk

35% increase in range so pilots can fly longer in more combat scenarios

25% reduction in fuel consumption for enhanced mission capability
