GE Aerospace and Kratos Defense & Security Solutions, Inc. have secured an Engineering, Manufacturing, and Development contract with the United States Air Force for the F143-ZZ-100 turbofan engine. The propulsion system serves as an alternative power plant for the Joint Air-to-Surface Standoff Missile and related uncrewed aerial systems.
Operational Background and Dual-Source Strategy
Defense manufacturing requirements demand resilient supply chains and high-rate production for long-range strike systems and uncrewed platforms. The cooperation between GE Aerospace and Kratos addresses capacity constraints by establishing a second-source propulsion architecture for critical munitions. Developing an alternate engine variant mitigates single-source manufacturing risks, supports industrial base scaling, and ensures sustained production throughput.
Technical Architecture and Division of Roles
The technical core of the program is the GEK800 engine, officially designated by the military as the F143-ZZ-100. This powerplant is an 800-pound-thrust turbofan engineered specifically for long-range missiles, uncrewed combat platforms, and collaborative combat aircraft.
Under the cooperative framework, the companies share engineering, design maturation, and manufacturing responsibilities:
- GE Aerospace leads aerodynamic optimization, core engine development, and turbomachinery systems integration.
- Kratos focuses on low-cost design practices, rapid manufacturing architectures, and airframe integration compatibility for uncrewed platforms.
Testing, Maturation, and Validation History
The development began in 2023 under a Technology Maturation and Risk Reduction phase funded via corporate investment and support from the Air Force Research Laboratory.
Key testing milestones completed by the joint engineering team include:

Key testing milestones completed by the joint engineering team include:
- Over 50 ground-level engine start cycles conducted across Kratos and GE Aerospace test cells to validate ignition reliability and start sequences.
- Altitude performance and operational envelope verification executed in 2025 at Purdue University's Maurice J. Zucrow Laboratories.
Target Applications and Operational Scope
The F143 turbofan directly supports the Joint Air-to-Surface Standoff Missile enterprise, with modular adaptability for future collaborative combat aircraft and long-range uncrewed aerial systems. By combining volume-optimized fabrication methods with high-thrust turbofan efficiency, the program delivers repeatable flight performance, extended operational range, and a scalable industrial pipeline for mission-critical defense hardware.
