Camp Century and Project Iceworm caused significant environmental damage, but a potential benefit of the secret installation has recently emerged.

But hardly anyone knew the truth: Camp Century was also developing Project Iceworm, a network of complex tunnels and railway tracks that could house and transport some 600 nuclear missiles.

The Army decided not to risk the loss of hundreds of missiles if the facility collapsed, eventually canceling Project Iceworm just three years after Camp Century was built.

A NASA research aircraft spotted Camp Century, home to the secretive Cold War project Iceworm, deep beneath Greenland's ice.

Camp Century served as a cover for Project Iceworm – a covert plan to house a network of nuclear missiles in the ice, capable of striking the Soviet Union.

Scientists now have a clearer picture of Camp Century, an abandoned U.S. military base long hidden under the ice in Greenland, thanks to a NASA research team's good luck.

But in reality, Camp Century served as a cover for Project Iceworm, a covert plan to house a network of nuclear missiles in the ice, capable of striking the Soviet Union.
