An immediate move from Yamato to the larger A-150 design is judged unlikely in this scenario. Existing capital-ship construction already absorbs substantial Japanese resources, while the navy recognises that it needs more cruisers. Its preference for large battleships coexists with a concern for fleet balance. Submarines and destroyers also remain under development. Three additional years do not supply a large merchant fleet, so further battleships would leave that weakness unresolved.

A-150 construction competes with cruisers and fleet balance
Japan would probably postpone an immediate A-150 programme because its cruiser shortage and wider fleet requirements still need resources.
