Legal gun-calibre categories are set against a more operational way of understanding cruisers. In this interpretation, most Second World War eight-inch cruisers are scout cruisers rather than truly heavy ships. The Alaska class is the period's first convincing heavy cruiser, while the Deutschland class combines large guns with a design that does not satisfy that role. The distinction helps viewers test whether a classification describes treaty paperwork, armament, or the mission a ship can actually perform.
