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 23.8 cm (9.4 in), but the classification system for artillery rounded up to the next highest centimeter.

History[edit]

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 Osmaniye-class ironclads were rearmed with these guns in the early 1890s.[2]

Naval Artillery[edit]

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.[3]

German ship details:
  • Siegfried-class - The six ships of this class had a primary armament of three guns in an unusual arrangement. Two MPL C/88 single gun turrets were mounted side-by-side forward, while a third was mounted aft of the central superstructure in a single gun turret.
  • Odin-class - The two ships of this class had a primary armament of three guns in an unusual arrangement. Two MPL C/93 single gun turrets were mounted side-by-side forward, while a third was mounted aft of the central superstructure in a single gun turret.

The 24 cm K L/35 was also the primary armament of the Argentine Navy's Independencia-class coastal defense ships.

Argentine ship details:
  • Independencia-class – The two ships of this class had a primary armament of two guns, which were mounted in two single gun turrets, one fore and one aft of the central superstructure.

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.

Austro-Hungarian ship details:
  • Kaiser Franz Joseph I-class - The two ships of this class had a primary armament of two guns, which were mounted in two single gun turrets, one fore and one aft of the central superstructure.
  • SMS Kaiserin und Königin Maria Theresia - This ship had a primary armament of two guns, which were mounted in two single gun turrets, one fore and one aft of the central superstructure.

Coastal Artillery[edit]

Germany[edit]

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.[4] They remained there until the late 1930s.[citation needed]

Argentina[edit]

There are currently four guns belonging to battery No4 at Puerto Belgrano, Argentina.[5]

Turkey[edit]

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.[5]

Netherlands[edit]

Pampus, Netherlands

In the Netherlands, the artificial island fortress Pampus was built to block the approach to Amsterdam from the Zuiderzee It was armed with four 24 cm K L/35. This was a very powerful fortress, because the guns were protected by armored cupolas. The four guns cost 225,000 guilders. The two armored cupolas were ordered at Gruson for 953,000 guilders. The four carriages were also ordered at Gruson and cost 147,000 guilders.[6] These carriages were minimal port carriages, which allowed a minimal embrasure.[7]

Pampus was supported by two batteries which were only covered by earthworks. North of Pampus, at Durgerdam there was a battery of three 24 cm K L/35. South of it was Fort Diemerdam with three 24 cm K L/35.[8] In 1895 three emplacements for 24 cm K L/35 were made near Den Helder. There was speculation that the three guns from Diemerdam would be moved there.[9] In 1904 three emplacements for 24 cm K L/35 were made on the western side of Oostbatterij at Den Helder. The three 24 cm K L/35 from Durgerdam were to be moved to this position.[10]

Railway Artillery[edit]

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 Naval Base from 1941 until June 1944 when they were destroyed during the Battle of Cherbourg.[11]
