The Giant Viper is a trailer-mounted, vehicle-pulled, mine clearance system, designed to be deployed in areas containing land mines. It was developed for the British Army in the 1950s. It was designed to be towed behind a Centurion gun tank, FV4003, AVRE (Armoured Vehicle Royal Engineers); and also the FV432 Armoured personnel carrier. The Giant Viper uses rockets to launch a 250-metre-long hose, packed with plastic explosive, across a minefield. The Giant Viper hoses were filled, in the 1970s, at the Royal Ordnance Factory, ROF Chorley.
