Project Iceworm was the code name for a top secret US Army program during the Cold War to build a network of mobile nuclear missile launch sites under the Greenland ice sheet.
To test the feasibility of construction techniques a project site called "Camp Century" was started, located at an elevation of 2,000 m in northwestern Greenland, 240 km from the US Thule Air Base. The American radar and air base at Thule had been in active use since 1951.
Camp Century was described at the time as a demonstration of affordable ice cap military outposts. The secret Project Iceworm was to be a system of tunnels 4,000 kilometres in length, used to deploy up to 600 nuclear missiles, that would be able to reach the USSR in case of nuclear war.
