Why a better frigate cannot be in five places

How does the debate fit into naval strategy and fleet-building strategy?

Naval strategy is inseparable from maintaining enough hulls for simultaneous wartime tasks; greater capability per ship cannot replace presence in several places at once.

Qualitative improvement does not erase geography: one advanced frigate still cannot escort a convoy, screen a carrier, patrol an ASW barrier, and support troops ashore simultaneously. A ship may carry several assignments in peacetime, when demands are intermittent, but wartime tasks occur concurrently and in different places. Damage can also remove a sophisticated ship from the force without sinking it. Fleet planning therefore has to preserve enough hulls while replacements take years to arrive. The answer turns an abstract strategy question into a concrete lesson about presence, concurrency, and resilience.
