Caribou Air Force Station
Caribou Air Force Station was the first of five, United States Air Force, Air Material Command (AMC) installations that were constructed during the period of 1951 – 1953. Each of the five installations was built specifically to provide operational storage of the nuclear stockpile, and to provide a specified number of weapons to their adjacent Strategic Air Command (SAC) bases. The first four installations were built and occupied by 1953. The fifth installation, although completed in 1953, would not be utilized until 1955. The first installation, code named “Site Easy” was originally known as the “North River Depot”. It was constructed between 1951-1952, and operations began in 1952. Funds were provided in 1951 to the Armed Forces Special Weapons Project (AFSWP), for the planning and construction of an ordnance storage site in the vicinity of a new Strategic Air Command Base. The AFSWP was directed to utilize the services of the Corps of Engineers, Department of Army, for planning and construction, and was made responsible for monitoring such work, and for operational security measures during these phases. The original directive to the AFSWP stipulated that upon completion of construction the installation would be turned over to Headquarters, Air Material Command for operational responsibilities.
RAAF Operations Building Site
The operations building at Green Street was constructed in 1942 as part of the rapid development of the Garbutt air base, after the commencement of the war in the Pacific. The site chosen for the building was some kilometres from the air force base, in an undeveloped portion of land that contained one or two sheds and fowl houses. This area may have been part of the Town Common, providing a common area for grazing and tending to animals. The operations building did not need to be located on the air base, and in some respects, it was more appropriately sited off base. The activities carried out within the building were not strictly related to the daily operations at the air base, but were however, quite sensitive and extremely important to the Allied war effort.
