Tsushima, long-range fire, and Dreadnought's arcs

Tsushima is used to show how long-range engagement had changed naval gunnery: opposing fleets could be difficult even to depict together because of the distances involved. That lesson and the older memory of Lissa informed Fisher's aim of bringing six heavy guns to bear forward. Fisher expected that concentration to produce three hits in a minute and force an opponent to expose a larger broadside target in order to reply. He later suggested that a workable superfiring arrangement would have led him to add another turret rather than abandon the wing positions. Turbine power density and internal layout made the desired firepower practical within Dreadnought's hull.
