Jacko,
Carriers may be slow and costly but are possibly the only force projector available. HNS for Sierra Leone was a bit lacking for tactical FJs and RW wasn't it? Don't underestimate the "force for good" bit about NEOs and Disaster relief - CVF would provide a superb asset and do much for the UK's standing. In addition, a 36 ac wing of JSF is quite a considerable amount of "punch" if required, and a lot easier to maintain on a boat than in a dusty airfield. As Bismark suggests, at least the CBG takes all it needs with them and is not reliant on an already over-stretched AT fleet for resupply.
OA, I'm very well aware that most of the Typhoon money is spent. In addition, European sensitivities would preclude us from trying to barter for less. My take is, get T3 for all the flash toys then flog a load of T1/T2 jets to recoup some capital costs, and save on whole life costs for a couple of Sqns.
Then try and get back into the bomber business properly...
