How a damaged fleet would regenerate after a major war

After a major war inflicts heavy losses on both sides, how would fleets rebuild and what might replace today's battle-fleet model?

They would scale the technology that survived combat: uncrewed ships if autonomy worked, or numerous minimally crewed ships if cyber attack defeated it.

The next fleet's form depends on what the war demonstrates. If uncrewed ships operate effectively under combat pressure, reconstruction would emphasize them in large numbers. If cyber warfare makes autonomy unreliable, navies would favor minimally crewed ships that retain human control. In either case, heavy losses push the fleet away from a small collection of exquisite platforms and toward forms that can be regenerated at scale.
