U.S. Marines, Norwegian Home Guard, and U.K. Royal Marines establish a secure forward perimeter on Jan Mayen, Norway, Aug 29, 2026. This agile forward posture, demonstrated during Operation Atlantic City 26, is essential for controlling key maritime terrain and ensuring NATO can rapidly respond to any challenge in the High North. Atlantic City 26 is a Norwegian-led trilateral readiness initiative with the United Kingdom and United States designed to develop and demonstrate expeditionary advanced base capabilities and validate combined fires, maritime domain awareness, and sea denial to reinforce the security and stability of the High North. Jan Mayen is sovereign Norwegian territory in an isolated part of the Norwegian Sea, approximately 1,000 kilometers (620 miles) from mainland Norway. At the same time, the island occupies an important geostrategic position north of the Greenland-Iceland-U.K. gap, an area of water strategically significant to the defense of the U.S. homeland and northern Europe.
