Although Bristol Aero Engines acquired ramjet technology from the US company Marquardt, BAE put considerable effort into developing the Thor unit, including the construction of a high altitude test plant (HATP), with a supersonic test cell, at their Patchway site.
The Marquardt RJ43-MA were ramjet engines used on the CIM-10 Bomarc missile and on the D-21 drone.

A Shock-Induced Combustion Ramjet Engine (abbreviated as Shcramjet; also called Oblique Detonation Wave Engine (ODWE), or simply referred to as Shock-Ramjet Engine) is a new concept in airbreathing ramjet engines, proposed to be used for hypersonic, as well as, single-stage-to-orbit (SSTO) propulsion applications.
