U.S. Seeks Sovereign Bases in Southern Greenland

The United States is negotiating with Denmark to establish three sovereign U.S. military bases in southern Greenland, including the former Narsarsuaq airfield. Talks are being held under the 1951 U.S.-Denmark defense cooperation pact. The White House confirmed discussions are under way and described them as progressing in a positive direction. No final agreement had been reached as of early 2026.

Officials are focusing on three candidate sites in southern Greenland. Narsarsuaq is a leading option because it was built by the U.S. and still has runway and support infrastructure that could speed reactivation. Washington is seeking a legal arrangement that would designate the installations as sovereign U.S. territory, giving the Pentagon primary jurisdiction at the sites rather than relying on a status-of-forces agreement.

The U.S. currently maintains a limited military presence on Greenland centered on Pituffik Space Base in the far north. Most other U.S. facilities on the island were closed in the 1960s, leaving limited coverage of southern approaches. Military planners emphasize southern Greenland’s location near the Greenland-Iceland-United Kingdom gap, a corridor for naval and undersea movement between the Arctic and the North Atlantic.

U.S. officials link the proposal to increased Russian and Chinese activity in Arctic and North Atlantic waters and to concerns about contested access to high-latitude sea lanes. The administration has framed the talks as an expansion of defense cooperation with Denmark rather than an attempt to acquire territory. Denmark retains sovereignty over Greenland’s foreign and defense policy while Greenland’s autonomous government continues to seek greater self-determination.

Designating base sites as sovereign U.S. territory would differ from the typical overseas basing model. Under the arrangement Washington seeks, the Pentagon would hold primary legal authority on site, a status that goes beyond powers normally granted by status-of-forces agreements. If approved, the change would be one of the largest expansions of sovereign U.S. military territory in decades.

Greenland’s autonomous government does not control Denmark’s defense decisions, but local political opposition could complicate implementation and could strengthen arguments for greater independence. Danish officials have signaled openness to expanding U.S. access under the existing defense agreement. Greenlandic leaders have not formally endorsed the proposal.

Officials have not set a public timetable for finalizing any deal. NATO members, Moscow and Beijing are likely to watch the negotiations closely because of the potential effects on surveillance and military operations in the North Atlantic and Arctic regions.
