U.S. Military Seeks Expanded Presence in Greenland Amid Arctic Concerns

The U.S. Military is working to expand its presence in Greenland, aiming to add special operations forces and establish operations in three modern areas on the island, according to testimony from Air Force Gen. Gregory Guillot, commander of North American Aerospace Defense Command (NORAD) and U.S. Northern Command. These efforts are driven by increasing strategic competition in the Arctic and the need to close vulnerability gaps.

Growing U.S. Interest in Greenland

General Guillot informed the Senate Armed Services Committee on March 19, 2026, that discussions are underway with both Denmark and Greenland regarding a wider American military presence. This expansion would leverage existing defense areas established through a 1951 agreement between the U.S. And Denmark, which controls the semiautonomous territory of Greenland.

Guillot emphasized the “exceptionally real” need for increased capabilities, including space systems to support the proposed Golden Dome missile defense system, the ability to launch fighter and tanker aircraft for defense against potential Arctic cruise missile threats, and ports for special operations forces and the Navy. He stated that having more capability along what he termed the “2 o’clock approach” – referencing Greenland’s eastern Arctic location – would be key.

Current U.S. Presence and Planned Enhancements

Currently, the U.S. Military operates Pituffik Space Base (formerly Thule Air Force Base) in northern Greenland. While Pituffik provides significant space capabilities, it has limited capacity for fighter and tanker operations. The proposed expansion aims to address these limitations by establishing additional locations for special operations and securing permanent access to Arctic waters.

Guillot highlighted the importance of strengthening collaboration with the Danish military, noting a “strong relationship” and a pursuit of “new and improved” ways to work together.

Recent Tensions and Infrastructure Improvements

The push for a bolstered U.S. Presence in Greenland follows a period of heightened tensions last year, sparked by former President Donald Trump’s expressed interest in acquiring the island. In response, allied nations deployed troops to Greenland as a demonstration of support for Denmark.

Alongside the expansion plans, NORTHCOM is focused on upgrading infrastructure at Pituffik Space Base, which has experienced “accelerated wear and tear” due to the harsh Arctic environment. Plans include runway repairs and the acquisition of a new special service vessel for coastal patrol.

Ongoing Discussions and Agreements

Discussions regarding the expanded U.S. Military presence are being conducted under the framework of the 1951 defense agreement between the U.S. And Denmark, with Guillot reporting “very, very supportive” engagement from the Danish government. The specific locations for the three additional areas of operation have not yet been disclosed, but will be located in areas different from the northern location of Pituffik Space Base.
