The 24 cm Schnelladekanone Länge 40, abbreviated as 24 cm SK L/40, was a German naval gun developed in the years before World War I that armed a number of the Imperial German Navy's pre-dreadnought battleships and armored cruisers. Later; a number of these guns were removed from naval ships and converted to coastal artillery; which would see service during World War I and World War II. The actual bore diameter was 23.8 cm (9.4 in), but the classification system for artillery rounded up to the next highest centimeter.
