Star Destroyers can be classified by what they carry and what they do. Their heavy weapons, organic air defence, troop capacity, and embarked fighters make them capital ships rather than destroyers in the modern escort sense. A standard Star Destroyer most closely resembles a battleship combined with an amphibious assault ship because its fighter complement is judged too small for a carrier-centered description. The Venator's stronger aviation emphasis supports a battleship-carrier-amphibious comparison. Mission and carried forces carry more classificatory weight here than the name attached to the design.

A Star Wars aside classifies Star Destroyers and Venators by weapons, fighter capacity, troops, and amphibious role.
