Why small classes made readiness difficult

Converted ironclads challenge the assumption that an older hull is automatically useless. In one- or two-ship classes, even nominal sisters could have machinery too different to share components. Dockyards therefore cannibalized ships in refit, borrowed compatible equipment from other vessels, or commissioned custom-built replacements according to fleet priorities. Reserve hulls and warehouse stocks could look inefficient in peacetime while remaining essential to operational readiness. The Victorian experience shows the risk of relying too heavily on just-in-time logistics when a fleet must replace equipment quickly.
