Oh, I want F35 for JCA - no doubt about that - it's a generation ahead and for the first time since the early 1970's, the RN would have a strike capability that could hang with the US.And have to buy all the fighters you're ever going to need in one go, before production ends (bang go any short-term savings), or buy an initial batch & some time in the future have to top it up with a batch of a different type, lumbering you with the costs of operating two types (& bang go any long-term savings).
Either way, we'd have to spend quite a bit of money right now to get at least a startup order for Shornet, and that's not going to happen in the life of the parliament we have.
At least with Shornet, the production line is there and working at a pace - the Rafale is ticking over at 1 a month more or less - they can ramp up a fair bit from there I'm sure but I guess an order of 36 or so would still be two or three years production. Makes no sense, the aircraft is starving for investment and the figures from Brazil put it at 7.2 billion USD for 36 vs 5.7 billion for the same total of Shornets to the same order (which I hope makes the figures directly comparable)
Nothing wrong with the Rafale per se, it just doesn't strike me as a great idea to buy it for the FAA.
