Deutschland-class cruiser
The Deutschland class was a series of three Panzerschiffe, a form of heavily armed cruiser, built by the Reichsmarine officially in accordance with restrictions imposed by the Treaty of Versailles. The ships of the class, Deutschland, Admiral Scheer, and Admiral Graf Spee, were all stated to displace 10,000 long tons (10,160 t) in accordance with the Treaty, though they actually displaced 10,600 to 12,340 long tons at standard displacement. The design for the ships incorporated several radical innovations, including the first major use of welding in a warship and all-diesel propulsion. Due to their heavy armament of six 28 cm (11 in) guns and lighter weight, the British began referring to the vessels as "pocket battleships". The Deutschland-class ships were initially classified as Panzerschiffe, but the Kriegsmarine reclassified them as heavy cruisers in February 1940.
