The Royal Navy has monitored nine Russian vessels around the UK in recent weeks, with some off the coast of Scotland

A surfaced submarine, destroyer, corvette, patrol ship, and their supporting tugs and supply ships were monitored by the Royal Navy ships in both the English Channel and waters close to the west coast of Scotland.

First Sea Lord, Admiral Tony Radakin, said: “This is why the Royal Navy is at sea every day, protecting the UK and our interests.

"Even with the pressures of Covid, we remain at short notice to respond to threats both in home waters and around the world.

"Despite the increase in Russian activity, both on the surface and underwater, we are always ready to respond.”

A patrol ship in the English Chanel also shadowed a surfaced Kilo-class submarine, the Stary Oskol, the corvette Boikiy, patrol ship Vasiliy Bykov and support ships.

Commander Philip Harper, Commanding Officer of HMS Severn, said: “In very challenging conditions with rough weather, Severn and several other British and allied ships, have spent 20 days ensuring that Russian transiting warships remain under our watchful eyes.”
