The Auxiliary Fire Service, first established in 1938 and amalgamated into the
National Fire Service during
World War II, was re-established as a voluntary service in 1948 alongside the
Civil Defence Corps as part of
civil defence preparations during the
early stages of the Cold War, with subsequent events such as the
Soviet Union detonating an
atomic bomb making their presence supporting civilians as part of Britain's civil defence an important role. In a report to the
Civil Service by the
Strath Committee, which was kept secret from the general population, it was thought that a
nuclear attack on Britain would cause
firestorms in major cities, which would overwhelm the ordinary fire service, so a large stock of basic fire engines was ordered to form a reserve capacity. The Green Goddess machines were not primarily fire engines (AFS members referred to them as "appliances"), instead being titled "self-propelled pumps", with some being
two-wheel drive (4×2), and others in
four-wheel drive (4×4) configuration. In the event of a nuclear attack on Britain, as part of a 125-vehicle AFS 'Mobile Column', Green Goddess appliances were to be deployed in a relay system of up to to pump huge quantities of water from lakes, rivers, canals and other sources to regular firefighters in affected cities. Supported by AFS
Land Rover or
Austin Gipsy command cars equipped with
barometers for deployment uphill or downhill, Green Goddesses were stationed at regular intervals to boost water pressure; to transport large volumes of water from beaches or estuaries, three inflatable rafts equipped with portable pumps were provided on the back of
Bedford RL or
Commer Q4 'Transportable Water Unit' flatbeds, known informally as the 'Bikini Unit'. Firefighting was a secondary role. The Green Goddess remained in continuous use by the AFS, regularly being deployed on training exercises, until the disbandment of the Civil Defence Corps and the AFS in 1968 by the
government of Harold Wilson due to high costs and a lack of volunteers, having disbanded the Rescue Section and Ambulance and First Aid Section two years prior. ==Technical specifications==
