Kratos and GE Aerospace’s GEK800 Engine Receives U.S. Military Type Designation F143-ZZ-100 and EMD Contract Award for JASSM

The GEK800 engine, developed by Kratos and GE Aerospace, has received the U.S. military type designation F143-ZZ-100. The companies also received an engineering, manufacturing and development contract tied to the Joint Air-to-Surface Standoff Missile program, according to the GlobeNewswire announcement published August 17, 2026.

The engine is being selected as a second-source propulsion system for JASSM. That links GE Aerospace to a missile program while also extending the platform’s stated application toward small, low-cost engines for missiles and uncrewed systems.

The announcement does not disclose the contract’s dollar value, production timing, expected unit volumes or the revenue split between Kratos and GE Aerospace. The next markers are transition from development to production, customer-funded procurement and evidence that the engine wins additional missile or uncrewed-platform applications.
