UK and Allies Deter Russian Submarines from Targeting Undersea Cables

British and allied armed forces successfully tracked and deterred Russian submarines from targeting critical undersea infrastructure during a massive, month-long operation in the North Atlantic.

UK Defence Secretary John Healey announced on Thursday that the military closely monitored a Russian Akula-class attack submarine and two specialist spy vessels before they eventually retreated. The Norwegian Ministry of Defence confirmed that its P-8 maritime patrol aircraft and a frigate actively participated in the joint tracking operation.

A Direct Warning to Moscow

Healey stated that he made the operation public specifically to ensure Russian President Vladimir Putin knew his vessels had been detected.

In a direct warning during a Downing Street press conference, Healey said: "To President Putin, I say, 'We see you.' We see your activity over our cables and our pipelines, and you should know that any attempt to damage them will not be tolerated and will have serious consequences."

UK Prime Minister Keir Starmer reinforced the message, stating that Britain "will not shy away from taking action" against Russia.

The targeted area holds a vast network of undersea cables and pipelines that are vital to the UK’s daily functioning. These underwater channels carry 99% of the country's international telecommunications and data traffic, underpinning global banking, trade, and communications. Additionally, the pipelines supply half of the gas used to heat British homes.

The Russian operation notably involved specialist submarines from Moscow's Main Directorate for Deep Sea Research (GUGI). British forces left the vessels "in no doubt that they were being monitored" and that their attempted covert operation had been exposed.

The submarines have since left British waters and headed north. While there is currently no evidence of any damage to the underwater infrastructure, the Ministry of Defence stated it is actively verifying the integrity of the network.
