How does a navy decide between reconstructing an old battleship and building a new ship?
Short answerThe choice depends heavily on available yard capacity: free slipways favour new construction, while fitting-out capacity can favour a refit.
NotesRefit decisions depended on the allocation of industrial space. A navy with available slipways might prefer new construction, while capacity in fitting-out yards could make reconstruction more practical. The whole dockyard system constrained the choice, rather than the age of a hull alone.
