The 28 cm SK L/50 was a German naval gun that was used in World War I and World War II.SK - Schnelladekanone (quick loading cannon); L - Länge in Kaliber (length in caliber) Originally a naval gun, it was adapted for land service after World War I.
Description
The 28 cm SK L/50 gun weighed {{convert|41.5|t|ton}}, had an overall length of {{convert|14.15|m|ftin|sp=us}} and its bore length was {{convert|13.421|m|ft|sp=us}}. Although called {{convert|28|cm|sp=us}}, its actual caliber was {{convert|28.3|cm|sp=us}}. 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=
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=
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.{{Cite web|url=https://bunkersite.com/panzer/guns/28-50.php|title=28 cm SK L/50, Reused guns Atlantikwall, Armour and Armament | Bunkersite.com|website=bunkersite.com}}
