The Treaty of Versailles, which established the terms concluding World War I, restricted German naval shipbuilding to warships displacing no more than . Debates in Germany over the role and size of its navy continued through the 1920s, when increased naval shipbuilding in France and the Soviet Union prompted the Germans to begin drawing up designs for large capital ships. The first design, completed in 1928, called for a battlecruiser armed with eight 30.5 cm (12 in) guns in four twin gun turrets, based on the design for the s that had not been completed during the war. In 1933, Adolf Hitler came to power in Germany; he made clear to the naval command that he had no intention of building a large fleet to challenge British supremacy at sea. He was primarily concerned with the possibility of a limited war with France, which would require the protection of German sea lanes. To this end, he authorized two more ships—the —to augment the three "Panzerschiffe" (armored ships). These ships would displace 19,000 tons and have the same armament and speed as the "Panzerschiffe"; the extra tonnage would be taken up by increased protection. Hitler wanted to follow this course so he would not be seen as overtly flouting the Treaty of Versailles. He did not realize that such "unsinkable" commerce raiders would provoke Great Britain more severely than 26,000-ton battlecruisers armed with 28.3 cm (11.1 inch) guns, which would be regarded as inferior to all the Royal Navy battleships and battlecruisers then in commission.
