The U.K. and Norway have successfully repelled a flotilla of Russian submarines from North Atlantic waters, thwarting what defense officials describe as a direct attempt by Vladimir Putin to exploit the ongoing U.S.-Israeli war on Iran. A weeks-long joint military operation forced a Russian attack submarine and two spy vessels out of the U.K.’s exclusive economic zone on Thursday.
U.K. Defense Secretary John Healey and Norwegian Defense Minister Tore Sandvik confirmed the successful deterrence. Hundreds of personnel, alongside aircraft and a Royal Navy frigate, tracked the Russian vessels for over a month. The target was clear. Authorities believe the submarines, coordinated by Russia’s Main Directorate of Deep Sea Research (GUGI), were actively surveying critical undersea infrastructure.
Healey directly tied the maritime incursion to the Middle East crisis. He accused Putin of using the global focus on the Iran conflict as a smokescreen to escalate “malign activity” and “nefarious” infrastructure surveying against Europe. He also alleged Russia is simultaneously supplying drone components to Iran. No undersea cables or pipelines were damaged during the standoff, according to a detailed report by the Associated Press released on Thursday.

The withdrawal marks a rare public victory for European naval forces currently navigating intense internal scrutiny, including a recent espionage probe. The fleet finally vacated the area following sustained pressure. A coordinated response was essential to push the vessels out, a reality highlighted in global coverage by the Indian Express.
How the U.K.’s Aggressive ‘Shadow Fleet’ Policy Forced Russia’s Retreat
This was not a standard interception. The successful deterrence of GUGI submarines represents a drastic paradigm shift in British naval strategy. In late March 2026, the U.K. completely abandoned its passive monitoring role. The military declared it is now prepared to physically seize ships suspected of operating in Russia’s “shadow fleet.”
For years, European nations merely helped the U.S. and France monitor these vessels. That era is over. Katja Bego, a senior research fellow at Chatham House, noted that publicly “calling out” these incursions is the cornerstone of this new deterrence strategy. Naming and shaming the fleet strips away the deniability Russia traditionally relies on for deep-sea sabotage. By aggressively tracking and broadcasting the submarines’ locations, the U.K. and Norway neutralized the threat without firing a shot.
