Battlships filled roughly the same position heavy tanks once filled, big heavy hitters that could take a beating. But with the march of progress came their downfall, that and the adoption of different fleet tactics.
I suspect that the big Carriers will be replaced with something more akin to smaller carriers, kinda like what Japan uses. Though those are definitely just destroyers no carriers here. But yeah with VTOL large aircraft carriers will most likely end up being decommissioned or turned into portable hospitals or soemthing specifically the nuclear ones.
