The Royal Navy has monitored nine Russian vessels around the UK in recent weeks.
Every move made by the Russians – a surfaced submarine, destroyer, corvette, patrol ship and their supporting tugs and supply ships – was watched closely by eight Royal Navy ships from the English Channel to the Celtic Sea in a concerted operation over the last two weeks.
First Sea Lord, Admiral Tony Radakin, said:
Type 23 frigate HMS Northumberland watched the movements of Udaloy-class destroyer, the Vice-Admiral Kulakov, as she sailed North West of the Outer Hebrides, off the west coast of Scotland.
Patrol ship HMS Severn was on duty in the English Channel and Dover Strait, where she shadowed a surfaced Kilo-class submarine, the Stary Oskol, the corvette Boikiy, patrol ship Vasiliy Bykov and support ships.
Severn was also on patrol as the Vice-Admiral Kulakov sailed through the English Channel as she headed north.
For some of the operation, the Russian ships sheltered from bad weather within the Baie de Seine, a bay in northern France, where Severn was joined by allied French Navy ships and aircraft.
Commander Philip Harper, Commanding Officer of HMS Severn, said:
HMS Lancaster joined Severn in this operation, closely tracking Steregushchiy-class corvette Boikiy in the English Channel and using her Wildcat helicopter to gather intelligence using the aircraft’s powerful array of sensors.
Meanwhile, three Royal Navy warships – HMS Tyne, HMS Richmond and HMS Kent – combined to escort the same group of Russian ships as they operated in the Celtic Sea and approaches to the South West coast of the UK.
This task group were joined by RAF Typhoon and F-35s jets, plus tankers RFA Tideforce and RFA Tiderace, which kept the allied ships replenished throughout the operations and contributed to monitoring duties while in the Irish Sea.
