"They kept an eye on it for a month": British ships monitored a Russian Navy frigate.
According to the statement of the British Navy, within a month the Royal Navy fleet was busy monitoring the movements of a Russian Navy ship:
During the month-long operation, ships and helicopters continuously monitored the Russian frigate and its accompanying vessels in the country's territorial waters.
Throughout April, patrol vessels HMS Tyne, HMS Mersey and HMS Severn, the tanker RFA Tideforce and Wildcat helicopters were said to have kept a close eye on the Admiral Grigorovich:
There wasn't a single day last month when a Russian warship and its exports weren't under close surveillance by the Royal Navy.
The Russian Navy frigate was reportedly moving between the North Sea and the Western Approaches, escorting Russian-flagged vessels bound for and from the Atlantic, Mediterranean, and Baltic Seas. It was escorting one submarine and six merchant and auxiliary vessels. The British press reported:
All this time, under the noses of our ships, the Admiral Grigorovich was escorting vessels of the Russian shadow fleet.
The patrol ship HMS Mersey (P283), a River Batch 1 vessel, accompanying the Admiral Grigorovich:
Commander-in-Chief of the Royal Navy, Vice-Admiral Steve Moorhouse, said the operation "demonstrated professionalism, resilience and operational readiness":
The Navy has proven its ability to generate a capable and combat-ready force, ensuring continued maritime security through leadership, teamwork, and operational excellence.
Helicopter escort of the Admiral Grigorovich:
All three patrol vessels shadowing the Admiral Grigorovich are River Batch 1 class vessels with a full-load displacement of approximately 1,7 tons. They are modestly armed, suited to police duties—a single 20mm cannon and machine guns. They are called the "workhorses" of the fleet due to their high intensity of use. Unlike destroyers or frigates, which can remain in port for extended periods, these three ships spend up to 300–320 days a year at sea.
They are often the first to intercept and escort Russian Navy pennants as they transit the English Channel or move near British waters. To ensure the ships can operate virtually non-stop, a rotating crew system is used. Each ship has a standard complement of approximately 30–45 personnel, but additional crews are available: while one crew is at sea, the other rests or trains ashore. This allows the ship to enter port only for refueling and minor repairs.
Between 2017 and 2019, they were slated for decommissioning as ships of the improved River Batch 2 project entered service. However, command realized that, given the constant reduction in warship components, they would be useful. Ultimately, they were modernized, thereby extending their service life.
