ROF Glascoed (today BAE Systems Munitions Glascoed) was initially a UK government-owned, Royal Ordnance Factory (ROF). It was designed as one of 20 munitions filling factories. It was planned as a Permanent ROF with the intention that, unlike some other similar facilities, it would remain open for production after the end of World War II. After privatisation of the Royal Ordnance Factories in the 1980s it became part of Royal Ordnance plc and later a production unit of BAE Systems. It was served by the Great Western Railway's Coleford, Monmouth, Usk and Pontypool Railway from its opening in April 1940 until 1993.
