British naval forces have discovered an extensive network of Russian surveillance devices in waters surrounding the United Kingdom, according to an investigation by The Sunday Times that reveals a hidden underwater conflict threatening national security.
The Royal Navy has found sensors believed to have been placed by Moscow to track Britain’s nuclear submarines, including the four Vanguard vessels that carry nuclear missiles as part of the UK’s continuous at-sea deterrent.
Russian sensors that may have been attempting to spy on UK nuclear submarines were discovered by the military in the seas around Britain – the Times.

“There should be no doubt, there is a war raging in the Atlantic,” one senior British military official told the newspaper. “This is a game of cat and mouse that has continued since the ending of the Cold War, and is now heating up again.”
The discovery has prompted British authorities to reportedly advise citizens to prepare 72-hour survival kits containing water, food, medicines, and battery-operated radios in case of emergency blackouts resulting from potential sabotage of energy infrastructure.

According to the investigation, Russia’s underwater operations target not only military assets but also critical civilian infrastructure, including the 1,200-kilometer Langeled pipeline from Norway that provides nearly 40% of Britain’s gas supply, and the network of 60 underwater cables that connect the UK to global communications and financial systems.
The Russian spy ship Yantar has been identified as a key vessel in these operations. Equipped with unmanned underwater vehicles and mini-submarines capable of reaching depths of 6,000 meters, it was spotted near data cables carrying information for companies including Microsoft and Google in November 2024.
In response, the UK has deployed the RFA Proteus, a deep-sea surveillance vessel purchased for £70 million and commissioned in 2023. The ship carries advanced underwater vehicles including the SeaCat, Gavia, and Defender, designed to locate and counter threats on the seabed.
Defence Secretary John Healey has been negotiating with Norway to strengthen cooperation against the Russian threat and has proposed a new program called Atlantic Bastion to develop surveillance capabilities.
The Ministry of Defence confirmed it is “committed to enhancing the security of critical offshore infrastructure” and is “strengthening our response to ensure that Russian ships and aircraft cannot operate in secrecy near the UK.”
Prime Minister Keir Starmer’s government has reportedly allocated billions of pounds in additional defence spending, acknowledging that the underwater threat requires immediate investment.

If Russia is using underwater surveillance on the UK it begs the question where else are they doing it? The US comes immediately to mind. They are a nation of supremacy who truly believe they cannot be touched. Worse, they never learn anything from history and always strive instead to be “politically correct” Their greatest weakness!
