Royal Navy Warns of Shadowy Russian Underwater Threat
22 Dec
Summary
- Russia is investing heavily in a secret deep-sea unit known as GUGI.
- This unit is capable of operating at extreme depths to sabotage infrastructure.
- The Royal Navy is enhancing surveillance with new underwater networks.

The Royal Navy has issued a stark warning regarding Russia's dedicated deep-sea sabotage unit, GUGI, which is reportedly resuming operations. This highly secretive group possesses the capability to operate at extreme depths, posing a direct threat to critical undersea infrastructure such as internet cables and gas pipelines. Recent intelligence indicates GUGI's subsurface capabilities have been reactivated after a period of setbacks, including a fire incident in 2019 that claimed the lives of 14 officers aboard the deep-diving submarine Losharik.
Concerns have escalated as one of GUGI's spy ships, the Yantar, was observed loitering over cables linking the UK and Ireland earlier this year. Despite Moscow's claims of research activities, the vessel's capacity to deploy submersibles capable of reaching 6,000 meters raises significant alarms about potential sabotage. Experts warn that GUGI could sever vital communication and power lines, impacting both Britain and its NATO allies. The Kremlin's continued investment in this unit, even amidst the war in Ukraine, underscores its strategic importance.
In defense, the Royal Navy is strengthening its capabilities through a new pact with Norway and a £4 million contract for the Atlantic Bastion surveillance network, featuring advanced acoustic sensors and autonomous vessels. Further investment is anticipated. The threat is considered immediate and serious, with naval chiefs emphasizing that the UK's island status offers a false sense of security. Recent incidents, like lasers being shone at RAF aircraft near Shetland, highlight the potential for miscalculation and escalate tensions.
