The remote Pituffik Space Base in northwestern Greenland, which Vice President JD Vance is visiting on Friday, is the U.S. Department of Defense’s northernmost installation. The base was built following a 1951 defense agreement between Denmark and the United States. It supports missile warning, missile defense and space surveillance operations for the U.S. and NATO. The Pituffik base is located on the northwestern coast of Greenland, about 750 miles north of the Arctic Circle and 947 miles south of the North Pole. It was known as the Thule Air Base until 2023, when it was renamed to recognize Greenlandic cultural heritage and reflect its role in the relatively new U.S. Space Force.
