NATO forces disrupt Russian Arctic submarine exercise near Svalbard targeting undersea cables

British, Norwegian and U.S. forces confronted Russian submarines in the Arctic this spring, disrupting a covert exercise near Norway’s Svalbard archipelago involving technology designed to disable undersea cables without clear evidence of sabotage, Reuters reported on Thursday.
Two Western officials told Reuters the operation was run by GUGI, Russia’s Defense Ministry directorate for deep-sea activities. The submarines used deep-sea submersibles to simulate deploying the secret technology, which officials said could damage cables without leaving obvious signs. The joint NATO operation tracked and confronted the vessels, preventing them from completing the exercise before they left the area.
Britain and Norway had disclosed in April that they detected covert Russian activity in the Arctic, but the U.S. involvement, the Svalbard location and the cable-disabling technology were not previously public. The two fiber-optic cables linking Svalbard to mainland Norway, stretching 1,400 kilometers and descending to 2,700 meters, carry critical satellite data from the SvalSat ground station.
Norwegian Defense Minister Tore Sandvik said the operation sent a message to Russia that covert activity would be detected and met with consequences. Western officials continue to monitor undersea infrastructure amid growing concerns over potential Russian sabotage targeting NATO members.
