The ramjet Gorgon IVs, made by Glenn Martin, were tested in 1948 and 1949 at Naval Air Station Point Mugu. The ramjet was designed at the University of Southern California and manufactured by the Marquardt Aircraft Company. The engine was 2.1 metres (7 ft) long and 510 millimetres (20 in) in diameter and was positioned below the missile.
A larger, fully-functional ramjet engine was then developed called Tory II-C. This was run at full power (461 MW) on 20 May 1964, thereby demonstrating the feasibility of a nuclear-powered ramjet engine. Despite these and other successful tests, ICBM technology developed quicker than expected, and this reduced the need for cruise missiles.

Power for the Strahlrohrjäger was to be provided by a Walter HWK 509 rocket engine for takeoff, and two Pabst ramjets. The rocket would provide enough initial velocity to start the ramjet engines which cannot produce thrust at zero or low airspeed. The ramjets were located on the tips of the sharply swept tailplanes and would be used for cruising.
Because it lacked the ramjet engine, it was mostly used for exploring the aircraft's aerodynamic properties and its systems. Its flight testing was terminated shortly after the ramjet-equipped Griffon II made its first flight two years later. This aircraft attained a maximum speed of Mach 2.19 and set a world record for a small closed course in ...
Aviation company Hermeus successfully demonstrated mode transition between turbojet and ramjet engines for the Air Force’s Quarterhorse hypersonic aircraft, a major hypersonic flight milestone.
The Lippisch P.12, P.13a and P.13b were related design projects for a ramjet-powered delta wing interceptor aircraft studied in 1944 by German designer Alexander Lippisch. The P.12 and P.13a were unarmed, relying on reinforced wings to ram its opponent. The P.13a and b were to be powered by producer gas made in-flight from powdered coal.
The other approach is to develop lower-flying cruise missiles propelled by an air-breathing ramjet engine that can sustain high speeds all the way to target. For both missile types, their biggest ...
