The German ship retains enhanced electrical fire control and a coincidence rangefinder because they offer credible gains in aiming speed and accuracy. Its hull is then narrowed and its draught adjusted for passage through the Kiel Canal, which works against the attempt to push speed upward. The resulting target of roughly 24 knots makes naval infrastructure a hard design limit alongside armour, armament, and available tonnage. British size and speed do not confer an automatic advantage in every technical area.

Fire control and the Kiel Canal shape the German maximum
Advanced German rangefinding is retained, but a narrow canal-limited hull and roughly 24-knot target constrain the design.
