If you can't afford to buy tailor made suits you buy "off the peg" - as the US did with our 70 Harriers - & the US Treasury must be laughing all the way to the bank...
The Harrier took many years to iron out the initial problems. The same will be true of the F35B - especially as the US will probably refuse to supply anything other than a flyable airframe!
That means MOD having to pay millions (billions?) more to kit the "bare bones" out with AI radars, weapon systems etc. - & we all know where that goes don't we! The A/C will be out of date before it enters service in a useable combat condition for the UK. Again, the US must be laughing - but they are nearly bankrupt & need our $$$........
