The closing question distinguishes elapsed time on a navy list from practical operational usefulness. The comparison target is a class with five or six years or less at peak combat value, rather than a ship that merely spent years in reserve. One disastrous member should not define a long-lived class, and Freya is the Victoria Louise-class outlier because coal soot repeatedly clogged her boilers. The question turns the class into a comparative procurement test: which designs lost their intended role even faster, and why?
