The 466,000-ton shipyard invites plans for another hundred destroyers and another hundred submarines. Capacity is available, but the fleet still needs a strategic purpose and an affordable budget. The joke about needing a war to justify a moderate defence budget points to the political side of expansion. Industrial capacity sets what can be built; policy decides what should be built.
