NATO allies, including Britain, Norway, and the US, successfully disrupted a Russian operation in the Arctic waters off Svalbard, where submarines were testing a secret weapon designed to sabotage undersea cables.

The operation, carried out by Moscow's GUGI undersea warfare directorate, involved deep-sea submersibles simulating the deployment of technology capable of disrupting vital cables for global internet connectivity and financial transactions.5

According to intelligence sources, the Russian vessels were tracked and confronted before they could complete their tests. The operation lasted almost a month and was monitored by RAF maritime surveillance aircraft and Norwegian forces.3

John Healey, former defence secretary, noted that the Royal Navy had been closely observing the Russian submarines, which included two GUGI submarines and an Akula-class attack submarine.1

The discovery of this new weapon and the details of the operation highlight growing concerns among Western intelligence officials about the Kremlin's increasing sabotage activities in Europe and potential preparations for conflict with NATO.46

The Ministry of Defence has declined to comment on the operation, but the incident underscores the ongoing tensions in the region and the importance of vigilance against such clandestine activities.

Key Insight
“The operation, involving Britain, the US, and Norway, tracked Russian spy vessels for almost a month, with RAF aircraft and HMS St Albans observing. Western officials fear the Kremlin is ramping up sabotage across Europe, with 99% of UK data carried by subsea cables.”
