A new era of combat propulsion

As we enter a new phase of near-peer competition, more capability is needed from the engines that power our military’s aircraft. GE is ready to answer that need with the XA100 engine. Designed, built and tested with the U.S. Air Force, XA100 is the world’s first flight-weight three stream adaptive engine. The XA100 engine represents the next generation of propulsion for the F-35.


Unrivaled performance validated by test

The time is now

The U.S. has long held an edge in advanced combat propulsion. To maintain this edge, we must act now to introduce revolutionary engine capability into our most advanced fighters. Backed by 14 years of development, GE’s XA100 is positioned to deliver game-changing performance to the F-35.

Giving pilots what they need, when they need it

Use the slider below to see how GE's XA100 can automatically configure airflow based on the pilot's mission scenario.

  • High-Thrust
  • High-Efficiency
  • High-thrust mode

    Directs the majority of air through the engine's core and fan streams, delivering greater thrust during combat engagements and helping pilots execute their missions effectively.

  • High-efficiency mode

    Directs air through the engine's third stream to dramatically reduce fuel consumption, provide greater range and allow pilots to persist longer in areas of interest with reduced risk.

Creating new operational possibilities

The XA100 enables a generational leap in propulsion capability without the tradeoffs associated with traditional engine architectures.

Adaptive engine

This adaptive cycle engine provides a high thrust mode for maximum power and high efficiency mode to extend mission range. Automatically transitioning between these modes dramatically transforms mission capability and enables unrestricted operations.

>10%more thrust

Third stream advantage

This advanced architecture provides an extra source of cooled air to improve both propulsive efficiency and fuel efficiency. Most importantly, it enables a step-change in thermal management capability to accommodate next-generation mission systems and provide higher thrust in and out of supersonic flight.

2Xthermal management capability

Advanced materials and components

Ceramic matrix composites (CMC) can withstand temperatures hundreds of degrees higher while being lighter weight and more durable than traditional materials. The use of additive manufacturing has reduced the engine’s weight and part count, and improves sustainment costs.
