Slack is not waste when a navy depends on items that the open market cannot replace during a crisis. The original logic of just-in-time supply retained warehouses for scarce components while maintaining a steady flow of readily available parts. Warships, fleet tankers, stores ships, and specialized spares belong firmly in the difficult-to-acquire category. Additional hulls lower average unit cost, and steadier maintenance demand makes dockyard work more predictable and cheaper. Capacity held in reserve also creates room to complete major work deliberately instead of paying emergency prices after the schedule has collapsed.

Defence slack makes logistics more resilient
True just-in-time logistics distinguishes common parts from scarce items, while defence planning needs stores, spare hulls, and maintenance headroom for what cannot be bought quickly.
