HMS Seadog was a third-batch S-class submarine built for the Royal Navy during World War II. Completed in September 1942, she spent most of her career in Arctic waters, off Norway, but sank only one German ship in 13 patrols. In January 1945, she was redeployed to the Far East, meeting more success. On her first patrol in the area, the submarine rescued four American airmen. After two patrols, she and her sister ship HMS Shalimar sank five sailing vessels, two coasters, a barge, a tugboat and a Japanese tank landing ship. After the war ended, Seadog was sent back to England, placed in reserve, then sold for scrap in December 1947. She was ultimately broken up in August 1948.
