A peacetime fleet built only from top-tier ships may lack the numbers needed once war expands its missions. The newest combatants remain the core fighting force, but not every wartime task requires their speed, protection, or sensors. Older vessels can still escort, train, inspect, or provide command capacity and thereby release modern ships for harder assignments. That reserve depth matters especially when conflict lasts longer than assumptions of a short, decisive technological or nuclear exchange.
