The Green Goddess is the colloquial name for the RLHZ Self Propelled Pump manufactured by Bedford Vehicles, a fire engine used originally by the Auxiliary Fire Service (AFS), and latterly held in reserve by the Home Office until 2004, and available when required to deal with exceptional events, including being operated by the British Armed Forces during fire-fighters’ strikes (1977 and 2002).
