Well considering that having 3 different versions is daft when 2 will do fine. One VSTOL and one Conventional.
Also I don't get your being against exporting stealth. Its not like it is a big secret or that other countries don't have the expertise. China has stolen it. The UK has developed it too, sure with help for the US but BAe had an independent program, I think to prove that we could do it.
I think that the UK should scrap the VSTOL idea, fit the CVF with cats and go for the F-35C
