The super-battleship's layers of gun range

At this stage the proposed British ship carries twelve 18-inch guns, eighteen 9.2-inch guns and twelve 4.7-inch guns, alongside smaller weapons. The displayed ranges place the 18-inch battery at about 47.6 kilometres, the 9.2-inch battery at 30 kilometres and the 4.7-inch guns at 16.3 kilometres. That difference leaves approaching destroyers facing heavy secondary fire before they reach the lighter battery. These are game specifications, and the 18-inch weapons are acknowledged as possibly overpowered. The trial therefore illustrates the consequences of the chosen range settings without proving what an actual ship could achieve.
