GE and Lockheed Hit Milestone with Liquid-Fueled Hypersonic Ramjet Demonstration
GE Aerospace and Lockheed Martin demonstrated a liquid-fueled rotating detonation ramjet in tests, showing potential for faster, farther missiles with lower production costs. The compact ramjet combines GE’s rotating detonation combustor with Lockheed Martin’s high-speed inlet, and tests at GE’s Niskayuna center validated ignition and cruise operation. The companies plan further maturation of the propulsion system in 2026.
