 New blast doors were fitted in place of the previous wooden factory doors and the interior of the site was refurbished in the areas forward of tunnel 4.In about 1990 there was a plan to move the RGHQ to a much smaller bunker, formerly used by UKWMO, at Lawford Heath near Rugby.In the end this never happened, and the Drakelow site was decommissioned and sold in around 1993.
