U.S. Marine Corps Joint Light Tactical Vehicles, a Strikemaster mobile anti-ship missile system, and a Norwegian Army National Manoeuvre Air Defence System displace across austere terrain while under tactical escort by Norwegian Home Guard soldiers with 3rd Platoon, District 11, in Jan Mayen, Norway, Aug. 30, 2026. The displacement and interoperability assessment, conducted during Operation Atlantic City 26, evaluated combined command, control, and multi-domain connectivity to ensure NATO can rapidly coordinate layered fires and air defense across contested environments 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.
