{{main article|British shadow factories}}
In Britain, a '''shadow factory''' is one of a number of manufacturing sites built in dispersed locations in times of war to reduce the risk of disruption due to enemy [[strategic bombing|air-raids]] and often with the dual purpose of increasing manufacturing capacity. Before World War II Britain had built many [[British shadow factories|shadow factories]].

Production of the [[Supermarine Spitfire]] at its parent company's base at [[Woolston, Southampton]] was vulnerable to enemy attack as a high-profile target and was well within range of ''[[Luftwaffe]]'' bombers. Indeed, on 26 September 1940 this facility was completely destroyed by an enemy bombing raid. [[Supermarine]] had already established a plant at [[Castle Bromwich]]; this action prompted them to further disperse Spitfire production around the country with many premises being requisitioned by the British Government.<ref>Price 1986, p. 115.</ref>

Connected to the Spitfire was production of its equally important [[Rolls-Royce Merlin]] engine, [[Rolls-Royce Limited|Rolls-Royce]]'s main [[aircraft engine|aero engine]] facility was located at [[Derby]], the need for increased output was met by building new factories in [[Bentley Crewe|Crewe]] and [[Glasgow]] and using a purpose-built factory of [[Ford of Britain]] in [[Trafford Park]] [[Manchester]].<ref>Pugh 2000, pp. 192-198.</ref>
