HMS Varangian was a British built U class submarine, a member of the third group of that class to be built. Her commander was Lt. Geoffrey J Gellie RAN. The submarine carried out patrols in the Norwegian Sea, covering Arctic Convoys  and seems also to have been used in a training role. She was broken up at Gateshead in 1949. Her ship's bell (inscribed HMS Varangian 1943) is in the possession of the Royal Navy Submarine Museum in Gosport, UK. It was believed that Varangian was the submarine featured in the 1943 film We Dive at Dawn, due to the boat carrying the P61 pennant number. However the submarine in the film was in fact portrayed by other two boats: P614 and P615, with their final digit painted out to disguise the fact that there were two boats being filmed.
