As far as having the three ships so close together a la Pearl Harbor doesn't concern me; this was a photo op for a show of force. The ships rendezvous in blue water, do the photo shot and then disperse before the photo is released to the public.
But there should be at least three more escorts for each flattop, unless they are on station 20 miles out for security.
What about the Chinese, NORKS, Iranians, Russians all working on “Carrier Killer”, one-shot missile, capable of sinking an entire flattop???
