A multinational NATO fleet, led by Norway’s frigate Thor Heyerdahl and accompanied by allied warships and logistics vessels, has entered the strategic Barents Sea amid a major anti-submarine campaign targeting Russian nuclear-powered submarines. Since August 24, at least a dozen U.S., UK, and Norwegian P-8 Poseidon patrol aircraft have conducted around-the-clock hunt operations from bases in Scotland, Iceland, and Norway, focusing on suspected Russian Yasen-class submarines near the USS Gerald R. Ford aircraft carrier strike group. Intelligence reports confirm all three of Russia’s advanced Yasen-class submarines—the Severodvinsk, Kazan, and Arkhangelsk—are actively deployed at sea, sparking NATO’s largest concentrated anti-submarine effort in recent years.
