Admiral Scheer was a Deutschland-class heavy cruiser (often termed a pocket battleship) which served with the Kriegsmarine (Navy) of Nazi Germany during World War II. The vessel was named after Admiral Reinhard Scheer, German commander in the Battle of Jutland. She was laid down at the Reichsmarinewerft shipyard in Wilhelmshaven in June 1931 and completed by November 1934. Originally classified as an armored ship (Panzerschiff) by the Reichsmarine, in February 1940 the Germans reclassified the remaining two ships of this class as heavy cruisers.
The ship was nominally under the 10,160-tonne (10,000-long-ton) limitation on warship size imposed by the Treaty of Versailles, though with a full load displacement of 15,420 tonnes (15,180 long tons), she significantly exceeded it.
