Capital ship

The Capital Ships of a Navy are its "important" and "biggest" warships; the ones with the heaviest firepower and armor. There is usually no formal criterion for the classification, but it is a useful concept when thinking about strategy, for instance to compare relative naval strengths in a theater of operations without having to get bogged down in the details of tonnage and gun diameters. A capital ship is generally a leading or primary ship in a fleet.
