I recently ran this fleet against two NPR's in the same system.
Their ships were between 4km/s and 6km/s movespeed.
I wanted to create a carrier group that could lock down their system and conduct constant strikes on enemy targets.

Pretty much you keep the carrier at least 100million km away from the enemy fleet, and have it send out it's bomber sto launch missile strikes and then use the fighters to chase down lone targets and the battleship to destroy disabled enemy ships.
