The 28 cm SK L / 40 is a German 280 mm naval cannon from the interwar period and both world wars. The weapon was developed at the beginning of the 20th century and entered service with the Kaiserliche Marine in 1904. It was also used by the Kriegsmarine until the end of World War II. It was the main armament of the Braunschweig and Deutschland battleships, launched before World War I and included in the so-called pre-dreadnoughts. Incidentally, it can be added that Schleswig-Holstein belonged to the latter class, whose volleys fired at Westerplatte started World War II. The Krupp plant was responsible for the development and production of the 28 cm SK L / 40 gun. The total weight of the gun was approx. 45-46 tons, and its barrel was approx. 10.4 meters long. The initial velocity of the missiles ranged from 740 to 820 m / s, depending on the type of ammunition used. The cannon could fire projectiles weighing from 240 to 284 kilograms, and its maximum firing range was about 18,800 meters. It is worth noting that the 28 cm SK L / 40 gun was also used as coastal artillery, as well as a railway version of it, designated as 28 cm SK L / 40 "Bruno".
