HMS Seawolf was an S-class submarine of the Royal Navy. She was launched on 28 November 1935 and went on to serve in the Second World War.

Wartime career

HMS Seawolf had an eventful career after the outbreak of war. On 6 October 1939, she attacked the German light cruiser Nürnberg and the torpedo boat Falke in the Skagerrak, but none of the targets were hit. In April 1940, Seawolf sank the German merchant Hamm, and in November, claimed to have sunk the German merchant Bessheim. Bessheim was mined and sunk the previous day off Hammerfest, so Seawolf had probably attacked another merchant.

She was one of a number of submarines ordered to track the German battleship Bismarck before her eventual sinking. On 6 March 1942, Seawolf sighted the German battleship Tirpitz, along with her escorting destroyers Paul Jacobi, Friedrich Ihn, Hermann Schoemann and Z-25. The German ships had sailed from Trondheim, Norway with the intention of attacking convoy PQ 12.

HMS Seawolf arrived in Halifax, Nova Scotia in 1943 to help the Royal Canadian Navy in anti-submarine warfare training.[1] She was commanded from August 1943 until 23 August 1944 by Commander Denis Woolnough Mills, for whom Seawolf was his first command after being promoted from First Lieutenant of HMS Thunderbolt.

Seawolf was sold for breaking up in November 1945 to Marine Industries, of Montreal.
