Project Iceworm
The Army also imagined hundreds of miles of rail lines buried inside Greenland’s ice sheet. On Project Iceworm’s tracks, atomic-powered trains would move nuclear-tipped missiles in snow tunnels between hidden launch stations – a shell game covering an area about the size of Alabama.
In the end, Project Iceworm never got beyond a 1,300-foot (400-meter) tunnel the Army excavated at Camp Century.
