Industrial capacity shapes the naval arms race

Yonai's objection to the Yamato class becomes an industrial argument rather than a debate about the ships' fighting qualities. Japan lacked spare shipyards and supporting infrastructure, so battleship construction constrained its ability to add submarines, carriers, and other forces once war began. Britain could shift an existing maritime industrial base between escorts, capital ships, carriers, and repair vessels, while the United States could expand capacity on a still larger scale. Discovering the Yamato design might drive larger Lion-class successors or heavier guns, and Pacific experience would encourage larger carriers and more maintenance ships. The long-term arms race would therefore reflect differences in adaptable production as much as lessons from individual battles.
