I totaly disagree.
Carrier feature is a docking bay. If something like a corvette size ship could dock something. It need a lot of ship volume not avaible for other features.
So it lot weaker spects then non dock having corvett. that is the balance.
A heavy fighter build around one capital ship canon. Mike also sense. it makes it slow less agile slow fire rate but give it a great punch against bigger ships bigger then a fighter. But any multirole fighter beats it. That is the balans.
In space the difference is not that much between a carrier or battleship there is no need for flight deck. So balteship carrier hybrid would make more sense.
The difference would be the ratio bigguns vs docking hangars
A 4km long battle ship can have it all. But ik makes lot slower and very expensive
There is also this balanse. Big vs many small even out. Also by price.
I don't think we disagree. You're also addressing size issues that I hadn't considered. You are quite right of course.
