Joint operations involving British, Norwegian, and U.S. forces confronted Russian vessels in Arctic waters near the Svalbard archipelago earlier this spring, thwarting a clandestine mission to simulate the deployment of a new weapon designed to disable undersea cables.
The operation was carried out by Russia's GUGI (Main Directorate of Deep-Sea Research) undersea warfare directorate, which used deep-sea submersibles. The aim was to test a sophisticated technology capable of severing critical communication lines without leaving immediate evidence, according to two Western officials familiar with the matter.
While Britain and Norway previously disclosed uncovering covert Russian activities in Arctic waters in April, the specific nature of the new weapon, the precise location, and the involvement of U.S. forces had not been previously reported. The incident occurs amid growing concerns among Western intelligence agencies that Russia may be escalating sabotage operations in Europe and preparing for potential conflict with NATO.
U.S. intelligence analysts are increasingly worried that Russia might test NATO's mutual defense pact, Article 5. Destroying subsea cables could be a key element in such an effort, Western officials stated. These cables, some no thicker than a garden hose, are vital for global internet connectivity and financial transactions. Their strategic importance has made them targets in past conflicts, dating back to the First and Second World Wars.
The specific exercise targeted two 1,400 km fiber-optic cables linking Svalbard to mainland Norway, which lie at depths of up to 2,700 meters. These cables transmit substantial amounts of satellite data downloaded at the SvalSat satellite ground station, a key component of NASA's Near Space Network.
Russia's Defense Ministry did not respond to requests for comment, and the Kremlin consistently denies conducting sabotage operations or plotting confrontations with NATO countries. Some Western officials, however, argue that Moscow's targeting of European states has intensified as the front lines in Ukraine have stabilized. This has been evidenced by various confirmed violations in countries like Poland, Lithuania, and Romania, including an attempted drone attack on Leipzig/Halle Airport in August, which led to diplomatic responses from Germany.
In August, CIA Director John Ratcliffe reportedly visited intelligence counterparts in Moscow to warn Russia against escalating sabotage operations in Europe. It remains unclear if the covert subsea operations were specifically raised during that meeting.
British and Norwegian officials shared their findings with Moscow concurrently with the Arctic confrontation, hoping to deter future actions by signaling awareness of the technology. Russia did not damage any cables during the simulated deployment, which focused on the mechanics of using the technology in a conflict scenario with NATO. Details of how the technology functions were not disclosed.
Norway's Defense Minister Tore Sandvik stated that the joint operation sent a clear message to Russia that covert operations will be detected and met with consequences, emphasizing that escalating tensions in the High North are not in anyone's interest. Britain's Defense Ministry referenced earlier statements acknowledging attempted covert activities by GUGI in waters near Norway and Britain, with both Washington and London having imposed sanctions on the directorate.
The U.S. White House and the CIA declined to comment on the incident. The strategic importance of the area between Svalbard and mainland Norway, known as the Bear Gap, is underscored by the potential for escalation between Russia and NATO. Russian nuclear submarines from the Kola Peninsula use this gap to reach the Atlantic.
In a demonstration of NATO's joint operational capabilities in the High North, Britain reported deploying forces to Jan Mayen island in August, alongside Norwegian and U.S. allies. Norway is planning a new fiber-optic cable linking Svalbard and Jan Mayen to the mainland by 2028.
NATO allies have increased their focus on subsea infrastructure security since the 2022 destruction of the Nord Stream pipelines. Security experts view increased vessel activity near sensitive underwater infrastructure, known as "drifting," as potential preparation for sabotage. In response, initiatives like NATO's Baltic Sentry monitoring system and the UK-led Nordic Warden have been launched to enhance patrols of critical infrastructure.
Data indicates a rise in drifting activity in areas like the North Sea and the South China Sea in recent years, although activity in the Baltic Sea has seen a slight decrease. Despite this, at least 11 subsea cables in the Baltic Sea were reportedly damaged or cut between October 2023 and the end of last year. Analysts identify Russia and China as significant underwater threats, with Europe remaining vulnerable due to its expanding reliance on seabed infrastructure and a historically reduced capacity to protect it.
