Off Norway, NATO allies are running a 12‑day antisubmarine warfare drill called Arctic Dolphin to practice finding and countering Russian submarines. The multinational event brings together surface ships, maritime patrol aircraft and crews from Norway, Spain, Germany and other partners to sharpen ASW skills in the cold, confined seas that link the Arctic to the Atlantic.
That corridor is strategically vital because it connects Russia’s Northern Fleet and its ballistic‑missile submarines to the Atlantic and would be the passage for nuclear‑armed undersea forces in a major crisis. Commodore Kyrre Haugen, commander of the Norwegian fleet, noted that if those submarines reach the Atlantic they could threaten both Europe and the United States, underscoring why NATO prioritizes coordinated ASW patrols and exercises.
Arctic Dolphin focuses on detection, tracking and coordinated response, integrating ships, maritime patrol planes and allied command‑and‑control. Crews practice synchronizing sensors and assets across national lines in an environment made difficult by cold water, seasonal ice and intricate coastlines — conditions that challenge both submarines and their hunters and make realistic training especially valuable.
The drills come as Moscow has expanded its Arctic presence, deploying forces and testing long‑range and hypersonic weapons that complicate Western air and missile defenses. Those moves have heightened allied concerns about freedom of movement and the security of North Atlantic sea lanes.
Political tensions between the United States and some NATO partners have strained diplomacy — episodes such as President Trump’s comments about Greenland and threats of tariffs provoked debate in Europe — but military cooperation continues. Norwegian leaders and other NATO officers emphasize that defense relationships and interoperability remain essential despite political disagreements.
Reporters embedded on Norwegian ships observed allied platforms maneuvering to localize and prosecute simulated contacts, describing how the exercise sharpens routines and builds confidence that NATO can detect and deter undersea threats before they reach open Atlantic routes. Arctic Dolphin is one of several recent NATO and national activities to boost presence and readiness in northern seas, serving both as a technical test of ASW capability and a rehearsal in alliance coordination.
