Project Iceworm was the code name for a top-secret United States Army program during the Cold War to build a network of mobile nuclear missile launch sites under the Greenland ice sheet. The ultimate objective of placing medium-range missiles under the ice — close enough to strike targets within the Soviet Union — was kept secret from the Danish government. To study the feasibility of working under the ice, a highly publicized “cover” project, known as Camp Century, was launched in 1960. However, unsteady ice conditions within the ice sheet caused the project to be canceled in 1966.

Details of the missile base project were secret for decades, first coming to light in January 1995 and resulting in a political scandal, when the Danish Foreign Policy Institute (DUPI) was asked by the Folketing (Danish Parliament) to research the history of nuclear weapons in Greenland during the Cold War.

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 American Thule Air Base. The radar and air base at Thule had been in active use since 1951.

Camp Century was described[by whom?]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 (2,500 mi) in length, used to deploy up to 600 nuclear missiles, that would be able to reach the Soviet Union in case of nuclear war. The missile locations would be under the cover of Greenland’s ice sheet and were supposed to be periodically changed. While Project Iceworm was secret, plans for Camp Century were discussed with and approved by Denmark, and the facility, including its nuclear power plant, was profiled in The Saturday Evening Post magazine in 1960.

The “official purpose” of Camp Century, as explained by the United States Department of Defense to Danish government officials in 1960, was to test various construction techniques under Arctic conditions, explore practical problems with a semi-mobile nuclear reactor, as well as supporting scientific experiments on the icecap.[2] A total of 21 trenches were cut and covered with arched roofs within which prefabricated building were erected.[3] With a total length of 3,000 metres (1.9 mi), 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, designated the PM-2A and designed by Alco for the U.S. Army.[4] Water was supplied by melting glaciers and tested to determine whether germs such as the plague were present.

Within three years after it was excavated, ice core samples taken by geologists working at Camp Century demonstrated that the glacier was moving much faster than anticipated and would destroy the tunnels and planned launch stations in about two years. The facility was evacuated in 1965, and the nuclear generator removed. Project Iceworm was canceled, and Camp Century closed in 1966.

The project generated valuable scientific information and provided scientists with some of the first ice cores, still being used by climatologists today.

According to the documents published by Denmark in 1997, the U.S. Army’s “Iceworm” missile network was outlined in a 1960 Army report titled “Strategic Value of the Greenland Icecap”. If fully implemented, the project would cover an area of 52,000 square miles (130,000 km2), roughly three times the size of Denmark. The launch complex floors would be 28 feet (8.5 m) below the surface, with the missile launchers even deeper, and clusters of missile launch centers would be spaced 4 miles (6.4 km) apart. New tunnels were to be dug every year, so that after five years there would be thousands of firing positions, among which the several hundred missiles could be rotated. The Army intended to deploy a shortened, two-stage version of the U.S. Air Force’s Minuteman missile, a variant the Army proposed calling the Iceman.[6] The entire “Project Iceworm” idea must be viewed with the context of U.S. military inter-service rivalry of the late 1950s, as the U.S. Army competed against the Navy and Air Force for a share of America’s new and expanding nuclear deterrent. The Army’s nuclear power program, authorized in 1954, gave the Army the stepping stone it used to reach for greater nuclear clout.…
