To combat the German "Panzerschiffe", the French built two small s in the early 1930s. This in turn prompted the German navy to begin plans for a more powerful battlecruiser design. Since 1933, Erich Raeder, the head of the German Navy, had argued to increase the defensive qualities of the "Panzerschiffe", and to increase the offensive power of the main battery with the addition of a third triple turret. This was also the view of the "Kriegsmarine", which saw the 19,000-ton design as being unbalanced. Hitler agreed to increased armor protection and internal subdivision, but refused to permit an increase in armament. Finally, by February 1934, 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.
