Loring Air Force Base
In 1951, the Department of Defense (DOD) allocated funds for the construction of an ordnance storage site at Loring AFB. The designs called for a self-sufficient "maximum security storage area for the most advanced weapons of mankind". The mission of the facility would be the protection and maintenance of the weapons used by SAC. The facility was in the northeast corner of the base, and construction began on 4 August 1951. In addition to 28 storage igloos and other weapons storage structures, the facility included weapons maintenance buildings, barracks, recreational facilities, a warehouse, and offices.
