An ACC battle group is now nearing a trillion dollar investment meant for waging warfare from afar, and doing battle with conventionally-armed combat techniques. The last 10 years of Iraq, Afghanistan and elsewhere have shown us that classic warfare isn't operative any more. Swarms, UAVs, and other kill vehicles are in vogue and damned difficult to defend against.
Open waters, far, far away is where they should be with 24/7 air patrols armed with the nastiest FABs, Clusters, and wide area disperal weapons imaginable are called for.
If we lose a Kitty Hawk because of this, we cannot replace it unless the Chinese will loan us the money. If anyone here thinks the Chinese aren't helping Iran, go back and see who's been looking at the Sentinel.
