Description
[edit]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 called 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 obturation i.e. seals the breech to prevent escape of the expanding propellant gas.
Naval turrets
[edit]In shipboard use, these guns were mounted in twin turrets as the primary battery of three German battlecruisers: the two ships of the _Moltke_ class (SMS Moltke and SMS Goeben) plus SMS Seydlitz, each mounting five of these turrets for a total of ten guns.
Coast defense guns
[edit]A C/37 Coastal Mounting was utilised for coastal guns. Battery Coronel at Borkum, Germany mounted four guns and Battery Grosser Kurfürst at Framzelle, France mounted four.[1]
