Ordnance Factory at ROF Bishopton. The decision to close RNPF Caerwent was announced on 25 March 1965. Production continued during the following two-year rundown phase. The last Gosling motor was produced on 14 June 1966, before tooling was transferred to Bishopston. RAF Caerwent RAF Caerwent was transferred to US administration after Charles de Gaulle expelled the US military from France in 1967. Caerwent became part of the US Army European 'theatre reserve stocks' under the command of the United States Army's "47th Area Support Group Reserve Storage Activity", and became known as USADA Caerwent (United States Arms Depot Activity - Caerwent). The US Army spent over £4 million constructing 300 magazines and converting some of the former RNPF structures to conform to the required specification. The material stored included small arms ammunition, artillery shells (up to 8"), anti-tank mines, grenades, flares, and the multiple launch rocket system. The first shipments of shells, rockets, mines, flares and small arms ammo arrived early in 1968 with shipments arriving by rail as far as practicable. At its height Caerwent was among the larger ammunition supply depots in Western Europe, storing over 80,000 tonnes of conventional munitions, a substantial fraction of the US Army's European stocks. In 1990 Caerwent shipped 12,000 tons of ammunition to the Middle East and played a critical part in Operation Desert Shield and Desert Storm. Following the change in the political climate in Europe and subsequent scaling down of operations, the US Army announced it was to close down their storage operations at the establishment in June 1992. Over 60,000 tonnes of munitions were moved out over a period of less than ten months. The last batch was removed by train on 19 July 1993. The formal closure ceremony took place on 20 August 1993. Training centre Caerwent is now a major training area covering over , capable of sustaining up to 1,000 troops. There are not only over 400 buildings and bunkers on the site, but also a comprehensive road system, for logistics exercises and driver training. Improvements to the site were completed at a cost of £150,000 in November 2015. The 1st The Queen's Dragoon Guards are scheduled to move to Caerwent in 2028.
