Routine repair is how a navy prevents a small fault from becoming a wartime absence, rather than evidence that a carrier is useless. The comparison with HMS Eagle before Taranto shows the operational cost of postponing minor work until a ship can no longer deploy. The deeper constraint is fleet size, because two hulls leave little slack when one ship's maintenance has already been compressed to cover the other. Treating the carriers as the functional hub of the fleet makes timely repair and a larger pool of hulls questions of readiness rather than prestige.
