Royal Navy Executes 48-Hour Surveillance of Russian Warship and Sanctioned Oil Tanker
The Royal Navy deployed HMS Mersey and a Wildcat helicopter to shadow a Russian Steregushchiy-class frigate and a sanctioned oil tanker, maintaining close surveillance across 48 intense hours in the English Channel.

Operating from Portsmouth, HMS Mersey and the Yeovilton-based Wildcat helicopter tracked the movements of the Russian frigate RFN Soobrazitelny alongside the oil tanker MV Anatoly Kolodkin. Utilizing advanced radar and sensor technology, the Royal Navy gathered critical intelligence as the two vessels navigated westward through this strategic maritime corridor.
Coordinated Monitoring with NATO Enhances Maritime Security
A Royal Navy spokesperson confirmed the operation’s coordination with NATO, emphasizing the patrol ship and helicopter’s role in maintaining vigilant observation. As the vessels reached the western edge of the Channel, they separated: HMS Mersey tracked the Soobrazitelny eastward back through the Channel, while the Anatoly Kolodkin proceeded into the Atlantic Ocean.
Commanders Highlight Operational Readiness and Maritime Protection
Lieutenant Commander Dan Wardle, commanding officer of HMS Mersey, stated, “This mission underscores Mersey’s readiness and tactical capability in monitoring Russian naval movements within UK waters. Our seamless coordination with allied forces heightens situational awareness and strengthens our response capabilities, ensuring the security of our maritime environment.”
Fleet Commander Vice Admiral Steve Moorhouse added, “In today’s increasingly contested global landscape, the efforts of HMS Mersey and 815 Naval Air Squadron exemplify the Royal Navy’s unwavering commitment to defending the United Kingdom’s home waters.”
Recent Patterns of Russian Naval Activity Monitored by Royal Navy
This operation follows closely on the heels of a similar mission two weeks prior, when Royal Navy vessels shadowed two sanctioned Russian cargo ships and their escort warships as they traversed from the Mediterranean Sea to the North Sea.
During that mission, HMS Tyne, also based in Portsmouth, alongside a Wildcat helicopter from 815 Naval Air Squadron, monitored the Russian Navy’s Ropucha-class landing ship Aleksandr Otrakovsky and merchant vessel Sparta IV. Within 48 hours, HMS Tyne and its helicopter were redeployed to track another Ropucha-class warship, Aleksandr Shabalin, and cargo vessel MV Sabetta sailing westward through the English Channel.
