The UK and Norwegian militaries conducted a joint operation lasting over a month in the North Atlantic to deter Russian submarines suspected of malign activity aimed at surveying and potentially damaging undersea cables and pipelines critical to Western infrastructure. The operation involved a combined fleet of at least 13 warships, including a frigate, planes, and hundreds of personnel, successfully monitoring a Russian attack submarine and two spy submarines which eventually withdrew. This patrol initiative follows a UK-Norway deal to protect undersea cables and involves at least five British-made frigates purchased by Norway. The UK Defence Secretary John Healey warned that any attempts by Russia to damage such infrastructure would have serious consequences. This activity is part of a wider Russian undersea research program understood as a paramilitary operation with research ships, unmanned vehicles, divers, and explosives mapping cables and energy pipelines across Europe. The operation and warnings come amid increased Russian naval activity (30% rise near UK waters in two years) and broader hybrid threats involving cyber and sabotage attacks on undersea cables.
