GE just paired a fighter engine with vertical takeoff

Signals Inbox·July 30, 2026·Defense Tech

GE Aerospace and Shield AI have successfully lit the fighter-class engine planned for X-BAT, an autonomous combat aircraft designed to take off vertically without a runway. The bigger tension is that they are not inventing the propulsion system from zero. They are combining an F110 engine with more than 11 million flight hours and a thrust-vectoring nozzle first flown on an F-16 in the 1990s.

Q1What actually happened?

According to the official GE Aerospace announcement, engineers integrated the AVEN thrust-vectoring nozzle into an F110-GE-129E fighter engine. They then moved the nozzle through controlled sequences and successfully lit the engine. That proves the engine, nozzle, controls, and actuation system can work together on the ground.

Q2Why does X-BAT need a moving nozzle?

Because X-BAT is supposed to launch while standing vertically. The nozzle must rapidly point the engine thrust in different directions to balance and steer the aircraft before its wings can generate normal lift. A regular fighter engine pushes mostly backward. X-BAT needs that thrust to move fast enough to keep a fighter-sized aircraft stable while it rises from the ground.

Q3Is this completely new technology?

No, and that is part of the point. AVEN was originally developed for an F-16 thrust-vectoring program in the 1990s. It completed 73 hours of ground testing and 135 flight hours across 95 flights. GE and Shield AI refurbished that hardware and connected it to an F110 engine with more than 11 million flight hours. They are using mature fighter technology for a new vertical-flight problem instead of starting from zero.

Q4Why does runway-free flight matter?

Military runways are large, fixed, easy-to-find targets. X-BAT is designed to launch from ships, islands, roads, or remote sites, then fly more than 2,000 nautical miles. Shield AI says three X-BATs could fit in the deck space used by one traditional fighter. If that works, forces could spread combat aircraft across many smaller locations instead of depending on a few vulnerable airbases.

Q5Is this basically a smaller F-35B?

Not really. The F-35B carries a pilot and uses a complex lift-fan system for short takeoffs and vertical landings. X-BAT has no pilot, stands on its tail, and plans to use one vectoring fighter engine for vertical launch and recovery. It is also built around autonomy, with Shield AI’s Hivemind software expected to fly missions without constant GPS, communications, or human input.

Q6Does this prove X-BAT can fly vertically?

Not yet. Engine ignition on a test stand is very different from balancing an entire aircraft in the air. The propulsion system must still handle heat, vibration, weight, rapid nozzle movements, changing winds, and transitions between hovering and forward flight. Shield AI says first VTOL flights are scheduled for 2026, mission capability for 2028, and production for 2029.

Q7So what is the real signal?

X-BAT is moving beyond renders and into integrated fighter hardware. The interesting bet is not simply an autonomous jet. It is an autonomous fighter with a 1,000-nautical-mile combat radius, large internal weapon bays, and no runway requirement. If the vertical tests work, Shield AI could turn proven 1990s propulsion technology into a new way of spreading combat aircraft across ships, islands, and remote bases.
