Royal Navy patrol ship HMS Mersey has tracked the movements of a surfaced Russian submarine as it sailed through waters close to the U.K.
The River-class offshore patrol vessel was on watch as the Kilo-class diesel powered attack submarine RFS Rostov Na Donu sailed through wintry seas in the North Sea and English Channel on its journey from the Baltic to the Mediterranean.
Mersey reported on the movements of the Russian Black Sea Fleet submarine, so that NATO Allies could track her progress as she continued her onward journey.
Commanding Officer of HMS Mersey, Lieutenant Commander Will Edwards-Bannon, said: “All of us in Mersey are very proud of the part we play, here in our home waters, in fulfilling the Royal Navy’s role of protecting our nation’s interests.
“No patrol is ever the same as the last and we have conducted a particularly varied range of missions recently, culminating with the tracking of this Russian submarine as it passes the U.K.”
Mersey was also on duty when the Kilo-class submarine made the reverse journey in October last year, as she returned from operations in the Mediterranean back to the Baltic.
