24 cm K L/35
The 24 cm K L/35 was a German Naval Gun developed in the years before World War I that armed ships of the Imperial German Navy, Argentine Navy and the Austro-Hungarian Navy. Guns removed from ships of the Imperial German Navy were modified to perform Coastal Artillery and Railway Artillery roles and saw service in both world wars. The actual bore diameter was , but the classification system for artillery rounded up to the next highest centimeter. History. In 1888 Krupp designed the 24 cm K L/35 and started production to arm two classes of the  Imperial German Navy's coastal defense ships. Krupp also produced guns for export that armed one class of coastal defense ships for Argentina and one class of protected cruisers and one unique armored cruiser for Austria-Hungary. The Ottoman s were rearmed with these guns in the early 1890s. Naval Artillery. The 24 cm K L/35 was the primary armament of the Siegfried-class and Odin-class coastal defense ships of the Imperial German Navy. The 24 cm K L/35 was also the primary armament of the Argentine Navy's Independencia-class coastal defense ships. The 24 cm K L/35  was the primary armament of the Kaiser Franz Joseph I-class of protected cruisers and the unique armored cruiser SMS Kaiserin und Königin Maria Theresia. Coastal Artillery. During 1916 the Odin-class ships were decommissioned and disarmed. The 24 cm K L/35 guns salvaged from these ships were converted to coastal artillery. Three guns were emplaced at "Battery Bremen" on Norderney and three guns were emplaced at "Battery S1" on Sylt. They remained there until the late 1930s. There are currently four guns belonging to battery No4 at Puerto Belgrano, Argentina. Ottoman Empire purchased thirty 24 cm K L/35 guns  during the 1880s and a number of these engaged the allied naval forces during the Gallipoli campaign. Railway Artillery. Beginning in 1937 the six guns at Norderny and Sylt were converted to railway artillery and were collectively known as 24 cm Theodor Bruno Kanone (E). During the Battle of France "Theodor Brunos" equipped three batteries of two guns each. Later one battery of four guns defended Cherbourg from 1941 until June 1944 when they were destroyed during the Battle of Cherbourg.
