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) at their Patchway site, with a supersonic test cell.

The Bloodhound Mk.1 could attain a speed of Mach 2.2, while the Mk.2 was capable of just over Mach 2.7.
