I think the answer is, "It depends." It depends on the mission, for one thing. Once you've achieved air supremacy and run out of air targets, you may want to get some boots on the ground. One LCS can put a lot more boots on the ground than one CVN. I am skeptical that the U.S. will ever get involved in "Littoral" warfare, basically retaking the Arabian Penisula from the sea.
About as many as the loadout of a single V-22 Osprey or a CH-53 Sea Stallion actually.
