The Royal Navy Cordite Factory, Holton Heath, (RNCF), was set up at Holton Heath, Dorset in World War I to manufacture cordite for the Royal Navy. It was reactivated in World War II to manufacture gun propellants for the Admiralty and its output was supplemented by the Royal Navy Propellant Factory, Caerwent. After the end of World War II, the explosive manufacturing areas of the site were closed down and some areas of the site reopened as an Admiralty Research Establishment.
