ROF Dalmuir was an Engineering Royal Ordnance Factory owned by the UK government during World War II.
Part of the site of the former William Beardmore and Company's Naval Construction Works at Dalmuir, Clydebank, Dunbartonshire, Scotland was bought by the Ministry of Supply, in January 1939, and it was converted into an Engineering ROF.
ROF Dalmuir started production as a Royal Ordnance Factory under the control of the Ministry of Supply, it opened on 16 January 1941.
In August 1941 it was handed over to William Beardmore and Company to run as an Agency Factory; and it returned to ROF Management control in September 1944.
The main offices were hit in the Clydebank Blitz of 13 and 14 March 1941 and burned for three days; but the factory reopened in three weeks.
