U.S. Air Force Tests Rotating Detonation Engine to Enable Faster Lower-Cost Mass-Produced Missiles

The U.S. Air Force has conducted tests of a rotating detonation engine aimed at enabling faster, lower-cost missiles suitable for mass production. The rotating detonation cycle offers potential thermodynamic efficiency advantages over conventional jet and rocket propulsion, which could translate into reduced fuel consumption and manufacturing cost for cruise missiles and other air-launched weapons. The tests represent a significant step toward demonstrating the technology's readiness for integration into future missile propulsion programs.
