H Class Battleship Proposals - Design Escalation

Design Escalation

In early July 1940, Hitler ordered the Navy to examine new battleship designs and how wartime experience might be incorporated. A study was completed on 15 July, and contained several recommendations for the H-class ships, including increasing the freeboard and strengthening the horizontal protection. In order to maintain displacement and speed and accommodate the increased weight of the additional armor protection, the design staff drew up an informal design, known as "Scheme A." The design removed one of the main battery turrets to save weight; the propulsion system was also increased in power to keep the same speed as the original design. The original diesel-only system was replaced by a hybrid diesel and steam turbine arrangement. The staff also prepared a second design, "Scheme B", which retained the fourth turret and accepted a much higher displacement. This design also incorporated the mixed propulsion system. These studies were abandoned in 1941 after Hitler decided to halt further battleship construction until after the end of the war. The design staff therefore attempted to improve the armor protection for the H-class. The 1940 designs did not form part of the design chain that resulted in the H-41 through H-44 designs.
