A design can grow from a small ship as extra missions are added, or shrink from an unaffordable proposal as requirements are removed. Either approach produces compromises that a frigate, destroyer, or cruiser label cannot explain on its own. Different navies also use those labels for historical or political reasons. Successive generations of destroyers look very different, but the screening role persists as threats expand to include aircraft and submarines. Length alone is equally misleading: the County-class cruiser is compared with the shorter R-class battleship. Cruising requirements can make a cruiser longer than a battleship without giving it the battleship's role.

Why warship labels reveal less than roles and design compromises
Destroyer and cruiser labels change between navies and generations, while design requirements explain why ships grow and what they can do.
