It once held as many as 10,000 U.S. military personnel.

Moulton, standing, uses a surveying instrument during the construction of Camp Century, a U.S. military base in Greenland, in June 1959.<\/p>\n<p>(Pictorial Parade\/Getty Images)<\/p>\n<p>Plans for Project Iceworm considered placing around 600 missiles, at least four miles apart, in a deployment area as large as Alabama, according to the report. Mounted on rail lines, the missiles could be moved about to evade detection by the Soviets. This setup, the report said, would allow launching sites to be \u201crelatively invulnerable\u201d to enemy warheads, requiring a \u201cmassive blanket Soviet thermonuclear attack\u201d to destroy Iceworm launchers.<\/p>\n<p>The missiles would be be hidden \u201c28 feet beneath the surface of the Icecap,\u201d almost the height of a three-story building. <\/p>\n<p>For that reason, scientists drilled into Greenland\u2019s ice core to study its sub-layers and assess if Iceworm tunnels were viable. The work produced a nonmilitary benefit by gathering data that \u201chelped reveal Earth\u2019s climate history over the past 100,000 years,\u201d says Ronald Doel, a professor of history at Florida State University who co-edited the book \u201cExploring Greenland: Cold War Science and Technology on Ice.\u201d<\/p>\n<p>\u201cIceworm\u2019s potential promise certainly helped government officials to endorse and embrace the construction of Camp Century,\u201d he said. \u201cAt the same time, research on Greenland\u2019s environment was indeed required to successfully operate there and elsewhere in the Arctic.\u201d<\/p>\n<p>Some of those findings, for instance, were crucial for uncovering the effects of climate change. The frozen soil and ice collected beneath Camp Century provided scientists an early lengthy and detailed record of <a class=\"link\" href=\"https:\/\/www.science.org\/doi\/10.1126\/science.166.3903.377\" target=\"_blank\" rel=\"nofollow noopener\">Earth\u2019s climate from the last 100,000 years<\/a>, pioneering the kind of paleoclimatologic research that showed how human activities are warming the planet.<\/p>\n<p>            <img class=\"image\" alt=\"A Swiss-made snow removal machine cuts a trench during the construction of Camp Century.  \"   width=\"1200\" height=\"1494\" src=\"https:\/\/www.europesays.com\/dk\/wp-content\/uploads\/2026\/02\/1770379389_848_.jpeg\" decoding=\"async\" loading=\"lazy\"\/>         <\/p>\n<p>A Swiss-made snow removal machine cuts a trench during the construction of Camp Century in Greenland in 1959. <\/p>\n<p>(Pictorial Parade\/Getty Images)<\/p>\n<p>       Project Iceworm\u2019s legacy<\/p>\n<p>Project Iceworm was shelved in 1962, after it was deemed too technically difficult \u2014 the ice sheet shifts \u2014 and as the Navy and Air Force pursued less burdensome projects on Greenland. Also, American officials weren\u2019t sure if Danes would back the endeavor.<\/p>\n<p>Also, when Camp Century was decommissioned around five years after Project Iceworm was scrapped, the Army left hazardous waste behind, such as up to 52,000 gallons of diesel and radioactive materials, residues from the small nuclear reactor that had powered the base.<\/p>\n<p>Now, as the island\u2019s ice melts because of climate change, those contaminants might be thrown into the environment. \u201cThe remnants of Camp Century are being carried to the west coast of Greenland as ice flows in the ice cap, and at some point will be exposed,\u201d Doel said.<\/p>\n<p>This is, once more, another piece of bad news for Greenlanders. As the Inuit has gained more political independence from Denmark in the last few decades, such as home rule status, it also may foster a far more fierce opposition against American military moves on the island.<\/p>\n<p>\u201cToday, Iceworm serves mainly as a historical reminder that the U.S. has often viewed Greenland primarily through a security lens \u2014 with limited consideration for Greenlandic political interests,\u201d Nielsen said. <\/p>\n","protected":false},"excerpt":{"rendered":"As the threat of nuclear war loomed during the Cold War, the U.S. Army hatched a top secret&hellip;\n","protected":false},"author":2,"featured_media":927,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[5],"tags":[1186,26,57,1193,1187,1190,1189,1194,1192,1184,1195,75,1185,1188,1191],"class_list":["post-926","post","type-post","status-publish","format-standard","has-post-thumbnail","category-greenland","tag-camp-century","tag-denmark","tag-greenland","tag-history","tag-ice","tag-island","tag-kristian-nielsen","tag-mile","tag-missile-tunnel","tag-project-iceworm","tag-thick-ice-sheet","tag-trump","tag-u-s-army","tag-u-s-cold-war-plan","tag-year"],"share_on_mastodon":{"url":"","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/posts\/926","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/comments?post=926"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/posts\/926\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/media\/927"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/media?parent=926"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/categories?post=926"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/dk\/wp-json\/wp\/v2\/tags?post=926"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
