The 38 cm SK C/34 naval gun was developed by Germany mid to late 1930s. It armed the Bismarck-class battleships and was planned as the armament of the O-class battle-cruisers and the re-armed Scharnhorst-class battleships. Six twin-gun mountings were also sold to the Soviet Union and it was planned to use them on the Kronshtadt-class battlecruisers, however they were never delivered. Spare guns were used as coastal artillery in Denmark, Norway and France. One gun is currently on display at Møvig Fortress outside Kristiansand.
