Blue Steel Servicing facility at RAF Wittering

The Blue Steel Servicing facility at RAF Wittering is a 20th-century building featuring a reinforced concrete and steel frame, clad with pressed aluminium sheets, and has a rectangular shape.

The exterior consists of a flat-roofed double-height hangar that lacks windows. Access to the hangar is provided by pairs of large concertina doors on the east and west elevations. On the south side, there is a centrally placed missile loading bay that projects from the five central bays of the hangar, connecting to the main hangar floor through a sliding concertina door. This loading bay includes a 13-bay, single-storey garage range at basement level, which was originally used to store handling equipment, such as missile transporters and trolleys. Additionally, a narrow two-storey range along the north side of the hangar contains offices, a mess room, and toilet facilities.

Inside, the space is divided into 13 bays by steel-framed lattice roof trusses. The walls and ceiling of this large, environmentally-controlled storage area are sealed with insulated panels to minimize heat loss and prevent dust ingress, with most of these panels still in place. The loading bay was originally equipped with an overhead gantry crane, which has since been removed, that was used to transfer missiles from airfield transporters to the storage stillages in the main servicing hangar.
