How should Japan have used the resources committed to the Yamato class?
Short answerBuild capable destroyers, especially the numerous escorts needed to make a convoy system work.
NotesDestroyers receive priority when considering a better use for the resources committed to the Yamato class. Ships able to support a convoy system were especially important because Japan chronically under-resourced that mission. Numerous useful hulls performing fleet and trade-protection work offered more than another prestige capital ship. This choice links shipbuilding policy directly to the escort shortage that weakened Japan's wartime logistics.
