AWACS for the carrier is already planned, it's called Merlin Mk2 ASAC (Crowsnest to you and me), COD can be done either by Merlin Mk4 or CH47...
personally I think there is more chance of me winning the lottery (which I don't play) than the RN having 5 or 6 V22 to support 1 carrier (after all only 1 will ever be at sea at a time)
