Blue Steel Servicing facility at RAF Wittering

The building is constructed of a reinforced concrete and steel frame, clad with pressed aluminium sheets, and rectangular in plan.

Exterior A flat-roofed double-height hangar with no windows. The east and west elevations of the hangar are accessed via pairs of large concertina doors. Attached to the south side is a centrally placed missile loading bay which projects from the five central bays of the hangar and connects with the main hangar floor via a sliding concertina door. The loading bay has a 13-bay, single-storey, garage range at basement level, originally used to house handling equipment, including the missile transporters and trolleys. A narrow two-storey range along the north side of the hangar houses offices, mess room and toilet facilities.

Interior Steel-framed lattice roof trusses divide the interior space into 13 bays. The walls and ceiling of this large, environmentally-controlled storage area were sealed with insulated panels to reduce heat loss and to help prevent dust getting in. Most of these panels remain in place. The loading bay was originally fitted with an overhead gantry crane, now removed, used to transfer the missiles from airfield transporters onto the storage stillages in the main servicing hangar.
