The site was built specifically to store and maintain free-fall nuclear bombs, such as the Blue Danube. This specific purpose was reflected in the facility's layout. The site was roughly pentagonal in layout, and consisted of three large non-nuclear component stores, surrounded by earthwork banking, and a number of smaller storage buildings to hold the fissile cores.
The larger buildings stored the bomb casings and the high-explosive elements of the weapons. The smaller stores, known as 'Hutches', were constructed to hold the fissile core of the weapons, held within stainless steel containers sunk into the ground.
These hutches were further divided into type 'A' and 'B', with the 'A' type hutches having a single borehole for the storage of Plutonium cores and the 'B' type hutches having a double borehole for storing Cobalt cores.
