Aviation News – GE Aerospace and Lockheed Martin have successfully completed engine tests demonstrating a liquid-fueled rotating detonation ramjet designed for hypersonic missile applications. The breakthrough matters as it could bolt higher speed, longer range, and greater efficiency onto future U.S. strike capabilities.
The tests mark the first initiative between the two companies under a broader joint technology development arrangement aimed at advancing next-generation propulsion. The demonstration confirms the feasibility of rotating detonation technology in a missile-scale engine, a key step toward operational hypersonic systems capable of engaging high-value, time-sensitive targets.
Unlike conventional ramjets that rely on steady combustion, the rotating detonation ramjet uses continuous detonation waves to burn fuel and air. This process delivers higher thrust while reducing engine size and weight, improving range and overall performance at super- and hypersonic speeds and enabling more compact missile designs.
