The Royal Navy is tracking the movements of a Russian warship in the North Sea, according to national reports. The Mirror says HMS Portland is monitoring the Russian guided missile frigate Admiral Gorshkov and accompanying tanker Kama.
The vessel is in international waters but is close to the UK. The Type 23 frigate joined the Norwegian Coast Guard vessel Bergen, as the Russian ships transited south through the Norwegian Sea.
British boat Portland embarked with her specialist Merlin helicopter to track and report on the movements of the Russian ships through the North Sea. Both were equipped with cutting-edge sonars, sensors and torpedoes for specialist operations.
