Combat mission: Armour and armament is sufficient for engaging any enemy battleship on superior terms; speed and range are sufficient for operating in concert with modern light and heavy cruiser squadrons. Depending on the tactical situation, she may be employed as a cruiser leader, a fast wing for the battle line, or as a fast carrier escort.
