The Royal Ordnance Factory (ROF) Bishopton was a UK Ministry of Supply, World War II, Explosive ROF. It is sited adjacent to the town of Bishopton, Renfrewshire, in Scotland. It was built, with the Ministry of Works acting as Agents, as three separate, almost self-contained, explosive factories within the same perimeter fence. They shared a common Administration Group and Workshop Support Services Group. The factory was built to manufacture propellant, Cordite in the main, for the British Army and the Royal Air Force. It did not produce propellant for the Royal Navy in World War II as the Admiralty demanded, and got, its own propellant factories.
