The 28 cm SK L/45[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/45 gun weighed 39.8 metric tons (39.2 long tons; 43.9 short tons), had an overall length of 12.735 meters (41 ft 9.4 in) and its bore length was 12.006 meters (39.39 ft). Although designated as 28 cm (11 in), its actual caliber was 28.3 centimeters (11.1 in). It used the Krupp horizontal sliding block breech design (or “wedge”, as it is sometimes referred to) rather than the interrupted screw 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.
