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.
Bribie Island Second World War Fortifications
Colonel John Whitelaw, Commander Coast Defences, Eastern Command, inspected the Fort Bribie site during 1940–41 and advised on the required structures within the fort. His recommendations were carried out during 1941, and the fort was operational by early 1942. Construction work was undertaken by the Commonwealth Department of the Interior and cost approximately , including construction of the fortress buildings, administrative, logistical and residential structures, building works and engineering services. The Fort Bribie layout changed often, with the Command Post moving position and new buildings and dugouts being constructed. The fort contained two six inch gun emplacements, and a Battery Observation Post (BOP) to the north containing the Battery Command and Depression Range Finder with a Barr & Stroud Rangefinder on a concrete platform to the east of this structure. Whitelaw recommended that a Fortress Observation Post (FOP) be installed at Caloundra, to work in conjunction with the BOP at Fort Bribie. Many of the barrack buildings, recreation halls and ablution blocks were constructed of fibrous cement sheeting or timber on a concrete base.
