The STOVL variant of JSF isn't really what we want - it's what the harrier mafia at the top of the RAF want, and what the politicians want. The forces want something with decent bring-back, ie the conventional version. The new carriers will be designed for, but not fitted with, the cats and arrestor gear required - but it's not too late to bite the bullet and go for the full monty version. That way we get sea-based jets with good load capacity when there's no shore option, and land-based jets with good load capacity when HNS is available. Hmmmm....
