Reserve ships as insurance for refits and crises

The video challenges the assumption that an inactive ship is automatically wasted money, comparing reserve hulls with keeping replacement supplies on hand. Buying a class at an efficient production scale and holding some ships back can be cheaper than discovering decades later that missing hulls cannot be conjured during a crisis. A reserve ship can accept a crew while another undergoes an uninterrupted one- or two-year refit, preserving operational numbers and preventing schedules from being disrupted for deployment demands. The Type 45 power-improvement program illustrates the risk of having no margin, because major work reduced the availability of an already small six-ship class.
