British shadow factories were the outcome of the Shadow Scheme, a plan devised in 1935 and developed by the British Government in the buildup to World War II to try to meet the urgent need for more aircraft using technology transfer from the motor industry to implement additional manufacturing capacity. The term 'shadow' was not intended to mean secrecy, but rather the protected environment they would receive by being staffed by all levels of skilled motor industry people alongside (in the shadow of) their own similar motor industry operations.
