GE Aerospace has shed more light on its hypersonic propulsion programs, announcing on Sep. 22, 2025 the testing of a Solid Fuel Ramjet (SFRJ) propulsion system and a dual-mode rotation-detonation combustion ramjet at the Kennedy Space Center and the GE Aerospace Research Center in New York, respectively. ATLAS, attached as a fixed test article on the port (left)-side wing of the Starfighter – that reached supersonic speeds in the tests, “was funded by the Department of War via Title III of the Defense Production Act to scale up the technology for air-breathing propulsion to extend the range of munitions.” The mention of Mach 2.2 also gives an idea of the flight profile and launch sequence the carrier aircraft is required to achieve, in order to obtain the required airflow for SFRJ engines to ignite and begin producing thrust.
