Wow..a 65000 ton LPH. The USMC will be jealous.
Joking aside, what's to stop a MAG Configured airgroup going to sea continually? A balanced force of 12-18 F35, 4-6 CH47, 8-12 Medium SH, 8-10 AH and 4 MASC RW (plus some Royals) is pretty well capable of delivering appropriate effect in the vast majority of real operations that the CVF will ever be involved in (Diasater relief, Amphib "poise", limited Forced Intervention etc). The willy-waving value of a 30-40 ac F35B CAG is almost pointless in the real world, and only really of use in a high tempo war against a near peer....which (thankfully) is a very rare event. If we do need to alter the airgroup mid-cruise, then do so. After all, we're always told that HNS is available so staging/Strat AT shouldn't be a problem....
That should see the F35/CH47/CHF boys getting enough deck time and leave sufficient frames in the UK for training- assuming that the RW guys ever grow spare capacity or are pulled out of Afghanistan.
As I've said before, the F35 lines are long and there will be opportunity to buy extra frames if required (A,B or C) - in the same way that the F16 lines have run for years. It actually conveys the advantage of realising amortisation cost benefits and of buying more capable, later block number aircraft.
The priority now is not stealthy FJ ac, it is protected mobility for ground troops (vehicles/RW). At least this gets the hulls - we can make up the numbers, if appropriate, at a later date.
