Fleets had a wartime and a peacetime configuration. In peacetime, capital ships acted as more of a deterrence, and combined fleets would usually just have a single carrier capital ship as support, while a dreadnought would hardly be in use.
A carrier was considered as a multipurpose warship, possessing powerful combat capabilities while also serving as the best logistical support to a fleet, providing repairs, supplies, and other auxiliary tasks.
Meanwhile, the purpose of a dreadnought directly contrasted that of a carrier; it boasted both a devastating firepower and a thickly reinforced hull. It would not provide any logistical support to any other ships but only serve itself. Its very existence was to attack, attack, and attack again.
