People seem to be missing the JSF's new primary role for the RAF i.e. deep strike; I have to say, based on raw figures, it's the worst possible option available to us.
IMHO we've chosen not to finance a proper carrier capability, and seeing as a carrier's primary role is airpower projection, I personally see selling both ships (1 to the French and 1 to Brazil/India/Just taking the embarrassing financial hit of not completing the second) and buying an all A force for the RAF as the most effective way of getting as much airpower projection capability as possible...but that's just me. Plus it would free up resources for many urgently needed capabilities and upgrades.
