Overview
- Russian sensors and unmanned devices, suspected of espionage, have been discovered in British waters, including some washed ashore and others located by the Royal Navy.
- Military officials believe the devices were installed to monitor the UK's four nuclear submarines and critical undersea communication cables.
- The UK Ministry of Defence dismissed the findings as speculative, reaffirming the security of its nuclear deterrent, which has remained undetected for over five decades.
- The discovery follows earlier concerns about Russian surveillance activities, including the presence of the ship Yantar in UK waters in January 2025 and suspected sabotage in the Baltic Sea.
- UK Defence Minister John Healey has warned Russia of potential strong measures to protect British interests as tensions over hybrid warfare tactics escalate.
