"What about Aircraft carriers though?"
Well, a plane is essentially like the first stage for an A2A or A2G weapon, it's the booster for the missile or bomb. In space it will be easier to just streamline all of that down into a two stage weapon, a cruise stage and a terminal stage. The cruise stage will create an intercept with the target at high speeds and the terminal stage will perform last second guidance and avoidance to attempt to prevent itself being shot down before it can maximize it's destructive effect.
I figure even capital ships will end up being essentially flying torpedo magazines with low profile, low albedo hulls composed of radar absorbing composites backed by a layer of laser resisting material and a whipple shield. The only other weapon worth carrying will probably be large aperture NUV fiber lasers to counter enemy torpedoes.
Most space warships would probably be drones in-and-of themselves, because taking a hit is likely a death sentence, either your huge magazine of missiles cooks off and blows the ship into millions of coin sized chunks, or you get flashed with an NUV or XUV laser and instantaneously irradiated to death.
