Hypersonic Propulsion Advancements with GE Aerospace and Lockheed Martin

GE Aerospace and Lockheed Martin have completed ground tests of a liquid-fueled rotating detonation ramjet (RDRJ) intended for next-generation hypersonic missile applications. The campaign, conducted at GE Aerospace’s Research Center in Niskayuna, New York, represents the first project completed under a wider technology development agreement between the two companies. Breaking Defense reports that the tests validated ignition and steady-state operation of the RDRJ under conditions representative of high-speed missile flight.

Strategic Implications

This development may indicate a shift towards more efficient hypersonic propulsion systems. The RDRJ’s potential for compactness and lower takeover speed could translate into more flexible airframe options, particularly for air-launched or shipboard systems.
