Defense Engine Breakthrough: Kratos, GE Aerospace Succeed
29 Sep
Summary
- GEK800 turbofan engine achieved first ignition at Kratos' X-58 facility.
- The engine, designated F143-ZZ-100, is for advanced cruise missiles and UAVs.
- Kratos faces cash conversion challenges impacting liquidity and working capital.
Kratos Defense & Security Solutions and GE Aerospace achieved a significant program milestone on September 21, 2026, successfully igniting the GEK800 turbofan engine for the first time. This critical test, conducted at Kratos' X-58 facility, marks a 100% success rate for this development phase and advances the program toward large-volume production.
The GEK800, now designated the F143-ZZ-100 by the U.S. military, is an affordable, high-performance propulsion system intended for advanced cruise missiles and uncrewed aerial systems (UAS). This development supports Kratos' growth, reinforcing its execution capacity with a strong backlog and updated revenue guidance.
GE Aerospace benefits by adding a key military engine to its portfolio, complementing its commercial and defense momentum. However, scaling GEK800 production presents challenges for both partners. Kratos is contending with cash conversion issues, reporting negative free cash flow in Q2 2026 due to inventory build-up.
GE Aerospace also faces potential margin dilution from growth investments and inflation, impacting its Defense & Propulsion Technologies segment. Early-stage manufacturing for the GEK800 could temporarily affect overall operating margins.
