Being a tug for a vls barge includes AAW or strike depends on what you stuff the tubes with. A barge is all you really need with Standards as long as you have an Aegis or two around. to provide the targetting info once you start squirting the birds out the tubes. I was an NTDS/ Assistant CIC Officer on an AAW cruiser so I understand the concept of threat bearings, etc.
I can be a bit of an iconoclast. You should have seen the looks I got out of the fighter jocks in P'cola when I suggested hanging Phoenixes on S-3s for AAW. After all you're shooting at targets 100+ miles away, you really don't need a dogfighter to haul them up there and drive in circles until the hawkeye designates your targets, you just need a pick-up truck. The mod S-3 carries more birds at a lower price.
Long range stand-off weapons don't need a close-in capable platform. Some of the platforms outh to have some defense capabilities but not all since they are never ever going to see a foe at whites of their eyes range. A rough analogy is equipping the gun crews on a BB with rifles and pistos to repel boarders, useless. Similarly, do all coast defence batteries gunners, cooks, washers, etc, need to be infantry capable? (Pointe du Hoc not withstanding)
