North Atlantic: Russian submarines tracked near cables
British authorities say three Russian submarines were tracked for several weeks near critical undersea infrastructure in the North Atlantic, highlighting renewed concern over the security of submarine cables that carry the vast majority of global communications. According to the UK Ministry of Defence, the Royal Navy monitored the vessels with support from maritime patrol aircraft and allied assets. Norwegian forces also contributed to the surveillance effort. The submarines reportedly operated close to networks of communication cables and pipelines located within or near the British exclusive economic zone. Officials emphasised that the activity occurred in international waters, but warned that such operations illustrate the growing strategic importance of undersea infrastructure for both military and economic security.
Royal Navy and Norway monitor Russian submarine activity
British defence officials indicated that the operation involved the tracking of three submarines, including a nuclear-powered Akula-class vessel and two specialised deep-sea platforms associated with Russia’s Main Directorate for Deep-Sea Research (GUGI). These units are believed to possess equipment capable of operating at extreme depths and interacting with seabed infrastructure. The Royal Navy deployed maritime patrol aircraft equipped with sonar buoys to detect and monitor the submarines’ movements over several weeks. Norwegian forces also assisted in the surveillance effort, reflecting growing cooperation between NATO allies to protect critical maritime infrastructure across the North Atlantic.
Growing Russian naval pressure around British waters
The episode illustrates rising maritime tensions between Russia and Western states in European waters. Analysts note that the presence of Russian deep-sea assets near communication cables is closely monitored because around 95 % of global internet traffic travels through these underwater networks. The submarine activity also comes amid other recent Russian naval movements near the United Kingdom. In the same period, two oil tankers linked to Russia’s so-called shadow fleet were escorted through the English Channel by a Russian frigate, a transit closely followed by British naval forces. Together, these developments underline the strategic competition unfolding both on the surface and beneath the sea in Europe’s surrounding waters.
