She was named after Friedrich Wilhelm von Seydlitz, a Prussian general during the reign of King Frederick the Great and the Seven Years' War.[1] Seydlitz represented the culmination of the first generation of German battlecruisers, which had started with the Von der Tann in 1906 and continued with the pair of Moltke-class battlecruisers ordered in 1907 and 1908. Seydlitz featured several incremental improvements over the preceding designs, including a redesigned propulsion system and an improved armor layout. The ship was also significantly larger than her predecessors—at 24,988 metric tons (24,593 long tons; 27,545 short tons), she was approximately 3,000 metric tons heavier than the Moltke-class ships.
