The Russian frigate Admiral Grigorovich escorted about six merchant and auxiliary vessels, as well as one submarine, near the coast of Great Britain in April, while being continuously monitored by Royal Navy ships and aircraft.
The UK Defence Journal reported this, citing the British Navy.
According to the British side, Royal Navy ships and aircraft tracked the frigate throughout the month.
The operation involved the patrol vessels HMS Tyne, HMS Mersey and HMS Severn, the tanker RFA Tideforce, and Wildcat helicopters from the 815th Naval Air Squadron.
The Russian frigate was escorting one submarine and about six merchant and support vessels sailing between the Baltic Sea, the Atlantic and the Mediterranean.

Among the vessels escorted by Admiral Grigorovich, British analysts name the tankers MV Triumf, MV Kolodkin, MV Gefest and MV Universal.
A Navy Lookout report says Russia is increasingly using warships to cover the so-called “shadow fleet,” which transports oil in circumvention of sanctions.
