Maximum construction speed differs from the pace that an industrial policy may actually choose. A yard can build a supercarrier faster, yet stretching the work keeps its skilled labor continuously occupied. Finishing early would either create a production gap that disperses the workforce or force the navy to order and operate more ships. The long schedule therefore preserves capacity while limiting fleet growth, even though it looks inefficient at the level of one hull.

Why a shipyard may deliberately stretch a carrier build
A slow construction schedule can keep a specialized yard and its workforce continuously employed when the navy does not want more ships in service.
