Camp Century was an Arctic United States military scientific research base in Greenland.[1] It is situated 240 km east of Thule Air Base. It was part of Project Iceworm to install sites for launching nuclear missiles in Greenland. Powered by a nuclear reactor, the camp operated from 1959 until 1967. The base consisted of 21 tunnels with a complete length of 3000 m.


Construction on the camp and the sub-glacial nuclear reactor began without explicit permission from the government of Denmark, leading to a political dilemma for Prime Minister H. C. Hansen.[2]

Scientific research[edit]

Ice core samples from Camp Century were used to create stable isotopes analyses used to develop climate models.[3][4][5]
