This doctrine was a form of psychological deterrence rather than a battle plan. A state unable to build many ships could instead build a few that looked so formidable that an opponent's public and politicians demanded matching vessels before risking war. Tirpitz's risk fleet offers the contrast: it sought deterrence through a substantial number of ships rather than a few individually superior ones. The Japanese concept turned industrial limitation into a political weapon, even though it did not solve the operational problem of facing a numerically larger fleet.

Big ships and big guns as deterrence
A separate Japanese idea used exceptionally powerful ships to make foreign politicians doubt that their own fleets were sufficient.
