Kriegsmarine (Navy)

Germany was only allowed a minimal navy after the WW I because of the terms of the Treaty of Versailles.The Anglo-German Naval Agreement of 18 June 1935 allowed Germany to build a navy equivalent to 35% of British surface ship tonnage and 45% of British submarine tonnage; battleships were to be limited to no more than 35,000 tons.

Hitler began to ignore many of the Treaty restrictions when the Nazis came to power in 1933 and started accelerate the German rearmament.
Two years later in 1935 the Reichswehr was renamed as the Wehrmacht.
The newly formed German Wehrmacht contained of three sister branches: The army (Heer), the Air force (LuftWaffe) and the Navy (Kriegsmarine)
