The Marine ( listen (help·info))) is the navy of Germany and is part of the unified Bundeswehr (the German Armed Forces). It is deeply integrated into the NATO alliance. Its mission is protection of German and Allied territories as well as peace-keeping and peace enforcement operations.

The Marine traces its roots back to the Reichsflotte (Empire Fleet) of the revolutionary era of 1848 – 52. The Reichsflotte was the first German Navy to sail under the black-red-gold flag. Founded on 14 June 1848 by the orders of the democratically elected Frankfurt Parliament the Reichsflottes brief existence ended with the failure of the revolution and was disbanded on 2 April 1852. Thus for todays Marine the birthday is celebrated every year on the 14 June.

From 1945 to 1956, the German Mine Sweeping Administration and its successor organizations, made up of former members of the Kriegsmarine, became something of a transition stage for the Marine, allowing the future Marine to draw on experienced personnel upon its formation. In 1956, with West Germany's accession to NATO, the Marine was formally established. With the reunification of Germany in 1990 the Marine took over the former East German Volksmarine ("People's Navy").
