Project Iceworm was a top secret United States Army program of the Cold War, which aimed to build a network of mobile nuclear missile launch sites under the Greenland ice sheet. The end goal was to install a vast network of nuclear missile launch sites that could survive a first strike. This was according to documents declassified in 1996.[1] The missiles, which could strike targets within the Soviet Union, were never fielded and necessary consent from the Danish Government to do so was never broached.
To study the feasibility of working under the ice, a highly publicized "cover" project, known as Camp Century, was launched in 1960.[2] Unstable ice conditions within the ice sheet caused the project to be canceled in 1966.
