Video: Project Iceworm and Camp Century – The U.S. Army’s City Under the Ice

Wikipedia: To test the feasibility of construction techniques a project site called “Camp Century” was started, located at an elevation of 6,600 feet (2,000 m) in northwestern Greenland, 150 miles (240 km) from the US Thule Air Base. The project was to build a system of tunnels and deploy around 600 nuclear missiles, which would be able to reach the USSR in case of nuclear war. The missile locations were supposed to be periodically changed.

The missile locations were supposed to be periodically changed.

A total of 21 tunnels were built; these tunnels also contained a hospital, a shop, a theater and a church. The total number of inhabitants was around 200. From 1960 until 1963 the electricity supply was provided by means of the world’s first mobile/portable nuclear reactor “Alco PM-2A” [2]. Water was supplied by melting glaciers and tested to determine if germs such as the plague were present. It was discovered that the ice was moving much more intensively than had been anticipated and would destroy the tunnels and launch stations in about two years. The facility was therefore closed in 1966. Nevertheless, the project generated valuable scientific information and provided scientists with some of the first ice cores, still being used by climatologists today.
