Project Iceworm - Wikipedia, the free encyclopedia:
Project Iceworm was the code name for a US Army Top Secret proposal during the Cold War (a study was started in 1958), 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 Moscow 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 cancelled in 1966.
