AIRCRAFT CARRIER. The aircraft carrier is very effective against units and structures. This vesel carries 3 that will keep attacking the enemy until the target is destroyed they will keep landing to reload then take off again. Even better if the planes are killed dont worry as the aircraft carrier will just build new ones to replace them at no cost to you. They will attack anywhere on the map as long as the carriers can get within a good distance. Use the dolphins to support these and you will only need one or two of the vesles. GOOD LUCK.
