A rule of thumb for translating nominal ship numbers into usable force. One hull is a potential capability and a possible white elephant, while two make availability probable but uncertain. Three provide a practical capability because one can usually be made available, and four make that ability dependable. Five increase certainty, while six allow a navy to deploy and sustain the type at long range. The progression explains why procurement debates must ask how many ships can be kept ready, maintained, and forward rather than counting commissioned hulls alone.

How hull numbers become a deployable capability
One hull offers potential, while larger fleets create increasingly reliable availability and the ability to sustain distant deployments.
