GE Aerospace Secures US Air Force Contract For Its GE426 Engine – Everything To Know About The Latest Deal

• The GE426 is being developed as a next-generation engine for medium-thrust-class ACP missions.
• The contract will focus on improving engine capability, production readiness and cost efficiency for future ACP fleets.
• Separately, GE Aerospace said it has signed a commercial agreement with Japan Airlines.

GE Aerospace (GE) on Tuesday announced it had secured a U.S. Air Force contract tied to the development of its GE426 engine under the Autonomous Collaborative Platform (ACP) program.

The GE426 is being developed as a next-generation propulsion system for medium-thrust-class ACP missions, with a focus on performance, affordability and manufacturability for autonomous, uncrewed combat aircraft.

GE426 Program Moves Into Next Development Phase

The latest contract builds on GE Aerospace’s earlier work on the GE426 program. In August 2025, the company completed the engine’s concept design review, validating its architecture and advancing the overall design process.

Under the contract, GE Aerospace will advance the GE426 prototype engine through the preliminary design review stage. The company will also work to improve system capability, production readiness, and cost efficiency, while aligning the engine with U.S. Air Force requirements for the medium-thrust-class ACP fleet.

GE Aerospace has continued to expand its portfolio of small, cost-effective engines designed for large-scale production and deployment in autonomous combat platforms, collaborative combat aircraft, and other advanced defence applications. The portfolio also includes the GEK800 and GEK1500 engines, which are being developed in partnership with Kratos Defense & Security Solutions.

“We’ve proven we can rapidly move from concept to engine demonstration with the GEK800, and our focus now is on applying that process to the GE426 to ensure it provides the performance, affordability and readiness the war-fighter needs,” said Steve ‘Doogie’ Russell, vice president and general manager of Edison Works at GE Aerospace.

Japan Airlines Signs Long-Term GE Aerospace Agreement

Separately, GE Aerospace also announced a commercial agreement with Japan Airlines on Tuesday. The airline signed a 10-year maintenance and overhaul deal covering its Boeing 787 fleet.

As part of the agreement, GE Aerospace’s Brisbane, Australia, facility will provide repair and stock support services for the airline’s Boeing 787 avionics systems.
