An item referred to the magazine R.M. dated July 1937 reporting that the British Admiral some time ago started with studying in which manner the safety of the naval establishments along the east coast could be better protected. As a result was the gunpowder production at the arsenal at Woolwich (12.000 labourers) to be moved t another location. At Chorley (Lancashire), Bridgent (Glamorgan), Hereford (Herefordshire) and Irvine (Ayrshire) were new arsenals founded, each responsible for the production of explosive materials needed for the charges of shells, bombs, mines and torpedoes. The arsenal at Chorley to be completed in July 1939 with an area of 900 hectare and costs 4-6 million pound sterling was the most important of the four planned new arsenals. She was protected against the heaviest air attacks. There were totally 500 buildings there to be realized all on a safe distance from each other and with the use of as light as possible materials to decrease the damage as much s possible in case of a accidentally explosion. The arsenal at Pennbroke in South West Wales was reopened.
