The Last U.S. Base Standing in Greenland

Once home to a vast network of American military installations, Greenland today hosts only a single U.S. base. Yet recent statements by U.S. President Donald Trump have brought the island back into focus, reopening discussions over military expansion, sovereignty, and Arctic security.

One Active Base Remains

The United States’ sole installation in Greenland is the Pituffik Space Base in the northwest of the island. Staffed by around 150 personnel, the base plays a critical role in missile defense and space surveillance, with radar systems capable of detecting missile launches near the North Pole.

A Vast Cold War Presence

During World War II and the Cold War, the U.S. operated weather stations, airstrips, radar sites, and strategic facilities across Greenland. Airfields such as Narsarsuaq, Ikateq, and Kangerlussuaq served as vital transit points for bombers traveling between North America and Europe.

What Remains of Old Bases

Most former U.S. installations have either been abandoned or dismantled. Some airstrips, including Kangerlussuaq, have since been converted into civilian airports, while others remain in disrepair. A decommissioned radar station near Kangerlussuaq, nicknamed “Mickey Mouse,” still stands as a relic of the Cold War.

Plans for Expansion

Experts say restoring old bases would be difficult, making expansion near Pituffik the most realistic option. Proposals include deploying air defense systems to protect the base or increasing use of Kangerlussuaq’s airport. President Trump has also floated placing missile interceptors on Greenland as part of a broader defense shield.

Sovereignty and Security Concerns

Greenland, an autonomous territory of Denmark, and Copenhagen have both resisted any move that could undermine their sovereignty. While the U.S. already enjoys broad access under a 1951 defense agreement, Washington is reportedly seeking new arrangements. Officials cite long-term concerns over Russia, China, and growing Arctic competition as ice melt opens new shipping routes.
