However, the adoption of convoy escorts, especially in the Atlantic, greatly reduced the effectiveness of surface commerce raiders against convoys.įollowing the end of World War II in 1945, the Kriegsmarine's remaining ships were divided up among the Allied powers and were used for various purposes including minesweeping. Along with the U-boats, surface commerce raiders (including auxiliary cruisers) were used to disrupt Allied shipping in the early years of the war, the most famous of these being the heavy cruisers Admiral Graf Spee and Admiral Scheer and the battleship Bismarck. Wolfpacks were rapidly assembled groups of submarines which attacked British convoys during the first half of the Battle of the Atlantic but this tactic was largely abandoned by May 1943 when U-boat losses mounted.

The Commander-in-Chief of the Kriegsmarine (as for all branches of armed forces during the period of absolute Nazi power) was Adolf Hitler, who exercised his authority through the Oberkommando der Marine ('High Command of the Navy').Īmong the Kriegsmarine's most significant ships were its U-boats, most of which were constructed after Plan Z was abandoned at the beginning of World War II. When World War II broke out in September 1939, Plan Z was shelved in favour of a crash building program for submarines ( U-boats) instead of capital surface warships, and land and air forces were given priority of strategic resources. In January 1939, Plan Z, a massive shipbuilding program, was ordered, calling for surface naval parity with the British Royal Navy by 1944. Kriegsmarine ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under the guise of enforcing non-intervention, but in reality supporting the Nationalists against the Spanish Republicans. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines. In violation of the Treaty of Versailles, the Kriegsmarine grew rapidly during German naval rearmament in the 1930s. 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.

It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. 'War Navy') was the navy of Germany from 1935 to 1945. The Kriegsmarine ( German pronunciation:, lit.
