Oh Crap Crap
I did quote u by accident!!!
Whoopsy!!!!
Nah i think making a BS wouldnt be THAT hard. The BS need only 4 hard points, since each turret is a battery consisting of 3 cannons. Yes 4 turrets is still quite advanced, but If u have a look at the Pauk Fast Attack Boat (which i keep mentioning), it is VERY much possible as the creator used a seperate viechle addon to be placed on the main ship. Only problem is the turret remained on the ship even after you blew the main ship to hell and back (assuming your bombs didnt damage the turret), however the turret will just sink - but taking pot shots b4 sinking to a range where you can see the gunner, but they cant fire back. But I think it would be possible to make 4 turrets (On Front and Back of Ship, on top of each other), as well as walkable interior made by the Tales of War team: the LSD. I say its concievable, just needs a talented modder.
However we then have to add the Tomohawk launchers as well as the AA gun (the Phalanx plz!). So lets assume thats another 2-3 hard points.
PS
Too all the ship modders, make it realistic. Honestly 6 mavericks, AMRAMs or other heavy Anti Armour missiles SHOULD be able to take out a Battleship. Damn in Sum of All Fears, a single Mig missile (dont know what type) "almost" sunk the Aircraft Carrier!
