The United Kingdom, in collaboration with Norway and other allies, conducted a weekslong military operation earlier this year to track and deter Russian submarine activity near critical undersea cables and pipelines in the North Atlantic. The operation, which involved various naval and air assets, concluded with the Russian vessels departing the area. No damage to underwater infrastructure was reported.
Joint Deterrence Operation
The joint operation was initiated after British aircraft and warships identified a Russian attack submarine in international waters in the High North several weeks prior. UK service personnel assessed this submarine as a potential diversion. Subsequently, the UK and its allies, including Norway, identified and monitored other Russian undersea naval units from the Main Directorate of Deep Sea Research (GUGI) operating near critical undersea infrastructure within the UK's Exclusive Economic Zone and allied waters, though not in territorial waters.
UK officials stated that they believed Russia was attempting a covert operation. The allied forces undertook overt actions to ensure the Russian units were aware they were being monitored, preventing their operations from remaining concealed. Following these actions, both the GUGI units and the Akula-class submarine concluded their operations and returned to Russia.
Submarine Activity and Location
The Russian operation reportedly involved an Akula-class attack submarine and two specialist submarines from Russia's Main Directorate for Deep Sea Research (GUGI). GUGI is described by UK officials as a Russian military program designed to develop capabilities for surveying underwater infrastructure in peacetime and potentially damaging or destroying it during conflict. The submarines operated for approximately one month in and near Norwegian and British maritime areas, specifically within the UK's Exclusive Economic Zone, which extends 200 nautical miles from shore.
Allied Response
The Royal Navy deployed HMS St Albans, a Type 23 frigate, along with RFA Tidespring, and Merlin helicopters to track the Russian attack submarine. RAF P8 maritime patrol aircraft provided 24/7 surveillance, deploying sonobuoys during the operation, which covered thousands of miles. Norway's Ministry of Defense confirmed its deployment of a P-8 maritime patrol aircraft and a frigate in support of the operation. Naval vessels and aircraft remain on standby.
Official Statements and Context
UK Defence Secretary John Healey stated that British forces, supported by allied nations, tracked and deterred the activity of the Russian vessels. He clarified that the operation was made public to signal to Russian President Vladimir Putin that the activity had been detected. Healey warned that any attempt to damage underwater cables and pipelines would not be tolerated and would have serious consequences.
Norwegian Defense Minister Tore Sandvik confirmed Russia's operation in and near Norwegian and British maritime areas. UK Prime Minister Keir Starmer stated the government's commitment to protecting the British public from the economic impact of perceived Russian aggression and to defend national and economic security.
NATO countries have frequently expressed concern that Russia could use its spy ship fleet to sabotage underwater cables, which are vital for global communications, supporting international banking, trade, and internet data.
Russia has consistently dismissed these claims. UK officials maintain that Russia remains a primary threat to the UK and its allies. The submarine activity occurred amid ongoing international events, including the conflict in the Middle East.
Historical Context and UK Commitments
The UK has observed a 30% increase in Russian vessels operating near its waters over the past two years. Previous incidents have included the tracking of the Russian spy ship Yantar, a GUGI-associated vessel, near UK waters, which reportedly directed lasers at British pilots. The Royal Navy also recently completed ten days of monitoring Russian warships and a submarine in the English Channel and North Sea, utilizing HMS Somerset, HMS Mersey, RFA Tideforce, and Wildcat helicopters.
In response to these developments, the UK is enhancing its protection of critical underwater infrastructure. This includes an additional £100 million allocation to support P8 submarine-hunting aircraft. The Atlantic Bastion program, guided by recommendations from the Strategic Defence Review, aims to transform the Royal Navy’s submarine hunting capabilities through autonomous systems and advanced sensors. These efforts are part of a broader increase in UK defense spending, projected to reach 2.6% of GDP by 2027, with an investment of £270 billion across the current Parliament. The UK continues to monitor the situation and collaborate with allies to deter activities perceived as threatening to British interests.
