A Russian submarine was deployed alongside the spy ship Yantar to map critical undersea infrastructure around Britain, including a gas pipeline in the Irish Sea.
The Ministry of Defence declassified a photo showing a submarine shadowing the Yantar last November, with a British anti-submarine helicopter and submarine also present.
This incident is part of a broader pattern, with the Royal Navy chief noting a 30 per cent increase in Russian incursions in UK waters over the past two years.
Concerns are heightened by Russia's renewed investment in its elite deep-sea submarine division, GUGI, which the UK sanctioned in June.
The UK government is responding with increased defence spending, new sanctions, and the Atlantic Bastion programme to protect critical undersea infrastructure.
