Aircraft have a scouting ability, they automatically reveal (I think it was 6 or 8?) hexes in all directions regardless of where they are parked. They don't have to launch a recon mission. SO the carrier is always going to have a scouting advantage, + 3 fighters to use offensively. The additional 1 move over a Battleship is also significant tactically.
The Carrier can simply dance around in circles, staying out of the line of sight of the Battleships, and launch offensive missions over and over and over against them, sinking them all. Carrier + 3 fighters can take on an arbitrary number of battleships assuming no extra support from either side and an infinitely large ocean map.
Obviously neither of these things will be true so the tactical situation will be more interesting than that.
If the Carrier is launching missions outside of the battleships engagement envelope (3 tile bombardment range?), they are invincible. The trick will be to corner the carriers, either with your own units or using terrain as natural barriers.
The carrier can also bombard units further inland, and can hold BOMBERS as well as fighters (improved range), and atomic bombs. All in all, it's a very useful unit and will be worth the steep cost.
