She was armed with four SK L/40 guns arranged in two twin-gun turrets, one on either end of the superstructure. Her secondary armament consisted of ten SK L/40 guns; four were in single-gun turrets on the upper deck and the remaining six were in casemates in a main-deck battery. For close-range defense against torpedo boats, she carried fourteen SK L/35 guns, all in individual mounts in the superstructure and in the hull. She also had four underwater torpedo tubes, one in the bow, one in the stern, and one on each broadside.
