Watch as HMS Somerset shadows a Russian submarine as it passed through the English Channel.
The Plymouth-based ship located the Kilo-class diesel-electric submarine Krasnodar in the early hours of Friday morning as it sailed past the eastern coast of the UK.
HMS Somerset, a Type 23 frigate, then followed her through the Dover Strait and the rest of the English Channel over the weekend.
Commander Tim Berry, the Commanding Officer of HMS Somerset, said:
“Policing the sea both in home waters and further afield is core business for the Royal Navy.Escorting foreign warships, in this case a Russian submarine, through UK waters is just part of our ongoing effort to protect our island nation.”
Last month, Frigate HMS Sutherland is escorted two Russian warships sailing through the English Channel overnight.
