UK to Lead 10 NATO Nations in Expanded Patrols Against Russian Submarines

Joint Expeditionary Force Patrols

“We see you, we see your activity over our cables and pipelines,” British Defence Secretary John Healey said of Russian President Vladimir Putin, as 10 NATO nations prepare to expand naval monitoring operations.

Ten European countries will intensify naval, air, and ground patrols to track Russian submarine movements near vital undersea infrastructure, the Financial Times reported. The security expansion uses the UK-led Joint Expeditionary Force rather than creating a brand-new alliance.

HMS Prince of Wales Formalization

Member nations will formalize the enhanced military cooperation arrangement on November 10. The signing ceremony will take place aboard the British aircraft carrier HMS Prince of Wales.

The participating countries comprise Britain, Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, the Netherlands, Norway, and Sweden. The coalition aims to protect undersea cables, pipelines, and shipping routes linking Europe, North America, and Africa.

North Atlantic Submarine Tracking

The coalition expansion follows a British military operation in April 2026. Royal Navy warships and RAF surveillance aircraft tracked three Russian submarines near critical North Atlantic infrastructure for over a month.

The tracked vessels included an Akula-class attack submarine and two specialized submarines from Russia’s Main Directorate of Deep-Sea Research, known as GUGI. Defence Secretary John Healey warned that these specialized vessels can survey underwater infrastructure and potentially sabotage it during a conflict.

Undersea Cable Disruption

A Reuters investigation published in September revealed that British, Norwegian, and United States forces confronted Russian deep-sea vessels near Norway’s Svalbard archipelago. Two Western officials stated that the Russian ships tested technology designed to disable communication cables without leaving evidence.

Allied forces disrupted the exercise and forced the Russian vessels to withdraw before they completed the operation. No undersea cables sustained damage during the intervention.

Chief of Defence Staff Assessment

Britain’s Chief of the Defence Staff, Air Chief Marshal Sir Richard Knighton, acknowledged in an interview with the Financial Times that the UK needed to catch up with European allies in responding to Russia. Describing security risks, Knighton said, “This is the most dangerous period I’ve known in my adult life.”

Beyond European waters, Russian submarines have visited Algeria for official naval engagements in the Mediterranean Sea on at least three occasions. Meanwhile, melting Arctic ice is opening new shipping routes along Russian and Canadian coasts, drawing increased attention from the United States, NATO, and China.
