Secondary roles for an obsolete or unsuccessful warship

The closing response lists practical ways to extract value from a vessel that no longer merits front-line service. A sound hull might train crews, test guns, patrol fisheries, carry stores, house personnel or prisoners, or serve as a target. None of those duties required pretending that the ship could still defeat a modern opponent. The alternatives separate the sunk cost of the hull from the narrower question of whether it remained safe and useful for auxiliary work. This is a compact example of matching residual capability to a secondary mission instead of allowing prestige to dictate employment.
