In the 20th century, Bristol's manufacturing activities expanded to include aircraft production at Filton, six miles (10 km) north of the city centre, by the Bristol Aeroplane Company, and aero-engine manufacture by Bristol Aero Engines (later Rolls-Royce) at Patchway.
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.
