The final version is slightly shorter because its main turrets are brought closer together and the armoured belt is reduced in length. B turret retains a full circle of training, but the other positions sacrifice some arcs. The design accepts that compromise while falling short of the ideal arrangement. The hull still retains space and capacity for later machinery and equipment improvements without abandoning the core fast-battleship idea.

A shorter armour belt as the final compromise
Bringing the guns closer together shortens the protected length, accepting some firing-arc limits to release weight and growth margin.
