American and Japanese plans could more readily accept ammunition-intensive long-range firing because their expected campaigns moved toward their own support systems. Japan anticipated fighting nearer its home islands, while the United States could feed supplies westward from a vast industrial base. Britain would have to send shells and reinforcements around much of the world while retaining forces against European threats. Those geostrategic differences constrained British deployment and procurement choices and help explain why the three navies approached decisive range differently.

The comparison with British and Japanese planning shows how industrial geography and ammunition supply shaped ideas about long-range battle.
