Krupp produced most of the artillery of the Imperial German Army, including its heavy siege guns:  the 1914 420&nbsp;mm [[Big Bertha (howitzer)|Big Bertha]], the 1916 [[38 cm SK L/45 "Max"|Langer Max]], and the seven [[Paris Gun]]s in 1917 and 1918. In addition, [[Friedrich Krupp Germaniawerft]] built German warships and submarines in Kiel. During the war, Krupp also modified the design of an existing [[38 cm SK L/45 "Max"|Langer Max]] gun, which they built in [[Lange Max Museum|Koekelare]]. The gun called [[Batterie Pommern]] was the largest gun in the world in 1917 and was able to shoot shells of ±750&nbsp;kg from [[Koekelare]] to [[Dunkirk]].
Before World War I Krupp had a contract with the British armaments company Vickers and Son Ltd. (formerly Vickers Maxim) to supply Vickers-constructed Maxim machine guns. Conversely, from 1902 Krupp was contracted by Vickers to supply its patented fuses to Vickers bullets. It is known that wounded and deceased German soldiers were found to have spent Vickers bullets with the German inscription "Krupps patent zünder [fuses]" lying around their bodies.{{cn|date=March 2022}}
