Armor Model
Overview
Unlike their prewar sisterships, the S-class submarines built during World War II stood out for their extensive use of welding in their construction, as well as their increased fuel capacity. An extra torpedo tube appeared in the light hull. HMS Sturdy was built at Birkenhead between 1942 and 1943. The ship spent most of the war in the Pacific, sinking more than 30 Japanese ships.
