NA - Norwegian Home Guard soldiers with 3rd Platoon, District 11, post security while a Strikemaster mobile anti-ship missile system and a Norwegian Army National Manoeuvre Air Defence System are emplaced in Jan Mayen, Norway, Aug. 30, 2026. The integrated security and fires emplacement, conducted during Operation Atlantic City 26, tested the combined force's ability to rapidly deploy and protect multi-domain assets, ensuring NATO can establish layered defense in contested Arctic terrain. 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.
