"Admiral Scheer"s primary armament was six SK C/28 guns mounted in two triple gun turrets, one forward and one aft of the superstructure. The ship carried a secondary battery of eight SK C/28 guns in single turrets grouped amidships. Her anti-aircraft battery originally consisted of three L/45 guns, though in 1935 these were replaced with six 8.8 cm L/78 guns. By 1940 the ship's anti-aircraft battery was significantly increased, consisting of six C/33 guns, four twin-mounted C/30 guns and up to twenty-eight Flak 30 guns. By 1945, the anti-aircraft battery had again been reorganized and comprised six 4 cm guns, eight 3.7 cm guns, and thirty-three 2 cm guns.
