Kriegsmarine
The Kriegsmarine (ˈkʁiːksmaˌʁiːnə, War Navy) was the navy of Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe, of the Wehrmacht, the German armed forces from 1935 to 1945. In violation of the Treaty of Versailles, the Kriegsmarine grew rapidly during German naval rearmament in the 1930s.
