For a chunk of British manufacturing, the Second World War began in about 1935 and lasted for ten years. The government’s decision to start to re-arm kicked into play an infrastructure aimed at armaments, initially with aircraft. The chapter begins by exploring census data to locate the places that were growing in population, it then matches these with the growing ‘new industries’ of radio, aircraft and motor vehicles. From the motor industry and armament companies came developments of the tank, and from radio and early television, radar. The shipyards began building again, and a network of Royal Ordnance Factories were set up to supply the forces. ICI produced tons of chemicals. As in the first world war, a huge range of companies turned their hand to war production. I wrote about the mechanisation of the army in WW2 in my book War on Wheels.
