Hitler acquiesced over the addition of the third turret. The new ship would displace and be armed with nine 28.3 cm guns in three triple turrets. To secure political freedom to build the new ships, Hitler concluded the 1935 Anglo-German Naval Agreement, which guaranteed Great Britain a 3 to 1 superiority in capital ships, and, more importantly, removed the limitations of the Treaty of Versailles for the German navy. The construction of new D-class cruisers were canceled to make way for Scharnhorst and Gneisenau. The provisional names of the planned D-class cruisers, Ersatz Elsass and Ersatz Hessen, were reallocated to the new ships, the contracts for which were awarded to the Kriegsmarinewerft Wilhelmshaven and the Deutsche Werke in Kiel. Construction was held up by 14 months, partly because Hitler wanted to secure the treaty with Britain before work began, and partly due to numerous design changes after the ships had been ordered. Because the maximum caliber of naval gun allowed under the Anglo-German Naval Agreement was 40.6 cm (16 inch), Hitler soon had second thoughts about the guns to be used for the new ships and ordered that they be armed with 38 cm (15 inch) weapons. The 28.3 cm turrets were readily available; 38 cm turrets would take years to develop, and Hitler wanted capital ships as soon as possible to fulfill his political ideals. He was also reminded that, despite the allowances of the Anglo-German Naval Agreement, the British had historically been sensitive about increases in main gun calibers aboard German capital ships. He therefore acquiesced to the ships' being armed with 28.3 cm guns, with the provision that they be upgunned to 38 cm at the earliest opportunity. The 38 cm turret was eventually used in the Bismarck-class battleships. General characteristics Scharnhorst and Gneisenau were long at the waterline; Scharnhorst was long overall, while Gneisenau had a slightly shorter overall length, at . The ships both had a beam of . They were designed to displace , which would have given the ships a draft of . At standard displacement of , which reduced draft to , while at a full combat load of , draft increased to . The ships' hulls were constructed from longitudinal steel frames, over which the outer hull plates were welded. Their hulls contained 21 watertight compartments and had a double bottom for 79% of their length. The German navy considered the
