Will growing destroyers bring back cruisers or battlecruisers as task-group leaders?
Short answerA larger crewed leader could protect its crew, defend itself, and retain firepower when accompanying uncrewed ships exhaust their weapons.
NotesA force built around large uncrewed surface vessels still needs a capable crewed leader. One option would give that ship armament comparable to its uncrewed companions. The preference here is for heavier armament because the leader must defend the people aboard and survive independently. Its remaining weapons could also protect the uncrewed vessels after they exhausted their own magazines.
