Moving Yamato's turrets exposed an industrial bottleneck

Did Japan need purpose-built transport arrangements for Yamato's gun turrets?

Yes; the enormous components required specialized movement, illustrating that factories and shipyards only work together when transport infrastructure connects them.

Yamato-class turrets required specialized transport and infrastructure. A first-rate turret plant and a first-rate shipyard did not form one production system unless roads, waterways, cranes, and ships could connect them. Moving an oversized weapon could therefore become as difficult as manufacturing it. The battleship's spectacular armament exposes the importance of transport links inside the naval industrial base.
