Capital ship

Capital ships are the most important and largest warships; the ones with the heaviest firepower and armor. There is usually no formal criterion for the classification, other than the fact that these ships tend to be heavily armed and armored. But despite the vagueness of this category, it is still 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 exact details of tonnage and gun variants. A capital ship is generally a leading or primary ship in a fleet, battlegroup, or Strike Force.
