i imagine that now Cameron has had a successful expedition the likelyhood is that both carriers will enter and remain in service, and that QE2 will get her cats...
much as i'm sceptical about JSF (though i'd love it to work it as advertised), and SH looks like an obvious alternative that would allow both QE's to sail the waves with biiiig airgroups as soon as they get into service, the problem seems to be the longevity of the programme - could SH/UH plausably remain in service till 2060?
would having a pair of QE's with 40 SH's apiece be 'better' than having QE's that we'd be lucky to get 20 F-35C's on?
