@Fargone: not saying aircraft arent as vulnerable to attack, but they can't carry the heavy weaponry surface vessels can. Surface is also cheaper to operate than aerospace(which already sees duty in aerospace combat, so now its overworked) and sometimes stealthier.

Also, what happens when your aircraft meet this?
