Description

edit

The 8.8 cm SK L/45 gun weighed 2.5 metric tons (2.5 long tons; 2.8 short tons) and had an overall length of about 4 meters (13 ft 1 in). It used a vertical sliding-block, or "wedge", as it is sometimes referred to, breech design.

History

edit

During World War I, the SK L/45 was used as anti-torpedo boat guns on all Imperial German Navy dreadnoughts and as main guns on torpedo boats and destroyers. The SK L/45 was also used to replace some of the 8.8 cm SK L/35 anti-torpedo boat guns on pre-dreadnought battleships.[2]

With the growing threat of aircraft, Krupp developed a high angle mount for the gun with a protective shield, known as the SK L/45 MPL C/13. The anti-aircraft gun was first installed on the battlecruiser Derfflinger and eventually all German capital ships had their 8.8 cm anti-torpedo guns completely or partially replaced with a smaller number of the 8.8 cm anti-aircraft gun.[3][4] This gun became not only the standard anti-aircraft gun on ships, but was also extensively used on every possible place where fixed anti-aircraft defence was needed.[3]

After World War I, the Treaty of Versailles imposed many restrictions on the German Reichsmarine and no new anti-aircraft gun could be developed before 1931.[5] As a result, the new light cruiser Emden, the three Königsberg-class cruisers and the heavy cruiser Deutschland were equipped by the now completely obsolete 8.8 cm SK L/45 C/13. Eventually these guns were replaced by the new 8.8 cm SK C/31 naval gun, 8.8 cm SK C/32 naval gun or the 10.5 cm Flak 38, with most ships being refitted by 1939.[6]

During the 1930s surviving SK L/45 guns were modified to use the same ammunition as the 8.8 cm SK C/30 naval gun and had similar performance.[2]
