A U.S. Navy nuclear-powered Los Angeles-class attack submarine has docked in Iceland, marking a rare and highly symbolic move in the North Atlantic. This deployment sends a strong message to Russia and China, amid rising tensions in the Arctic and GIUK Gap — a key maritime chokepoint between Greenland, Iceland, and the UK.In this video, we explore why this submarine stop is far more than routine. From Tomahawk missiles and stealth capabilities to Iceland’s strategic position within NATO, this maneuver is part of a broader effort to counter Russia’s growing submarine activity and China’s increasing presence in polar regions.With Russian Yasen-class submarines patrolling the Arctic and China declaring itself a “near-Arctic power,” the U.S. Navy’s message is clear: undersea dominance remains a top priority. We also look into the history of Keflavík Air Base, past visits by U.S. warships and B-2 bombers, and what this means for future NATO coordination.
