The 28 cm SK L/50[Note 1] was a German naval gun that was used in World War I and World War II. Originally a naval gun, it was adapted for land service after World War I.
Description
The 28 cm SK L/50 gun weighed 41.5 tonnes (40.8 long tons; 45.7 short tons), had an overall length of 14.15 meters (46 ft 5 in) and its bore length was 13.421 meters (44.03 ft). Although designated as 28 centimeters (11 in), its actual caliber was 28.3 centimeters (11.1 in). It used the Krupp horizontal sliding block, or "wedge", as it is sometimes referred to, breech design rather than the interrupted screw used commonly used in heavy guns of other nations. This required that the propellant charge be loaded in a metal, usually brass, case which provides obduration i.e. seals the breech to prevent escape of the expanding propellant gas.
Coast defense guns
In this role a dedicated C/37 Coastal Mounting was utilised. Battery Coronel at Borkum, Germany mounted 4 guns and Battery Grosser Kurfürst at Framzelle, France mounted 4.[1]
