Yamato and the opportunity cost of naval megaprojects

Yamato's value depends on what Japan gave up to build and support the class. In a constrained maritime industrial base, the ships absorbed personnel, facilities, and attention that might instead have produced cruisers and destroyers. A possible strategic case for Yamato was to publicize it as a status symbol and deterrent, perhaps making the United States hesitate until its own new battleships arrived. Japan undercut that rationale by concealing the ships when disclosure might have influenced an opponent's calculations. Used as wartime assets instead of advertised deterrents, the ships imposed an opportunity cost that made the already unbalanced fleet harder to sustain.
