sentences:  The armament was also significantly reduced to save weight and cost, from four heavy guns in two twin-gun turrets to two guns, each in single turrets; she also received two fewer secondary guns compared to "Fürst Bismarck".But rather than spreading the secondary battery along the length of the hull in casemates and sponsons, they were concentrated in a battery amidships, which reduced the amount of the hull that needed to be protected with armor, further saving weight and allowing thicker armor to be concentrated in the battery.Further weight savings were achieved by adopting a smaller superstructure and discarding heavy military masts in favor of lighter pole masts.
