Conrad Waters in his "Navies of the 21st Century" (a good read) suggests that whilst "real" carriers will probably be restricted to the USA, China & India in the foreseeable future there is a whole range of vessels avalable that can operate various combinations of fixed wing, STOBAR, STOVL & helicopters ranging from the QE's through the Kuznetsov to the Japanese "helicopter carrying destroyers" and the various assualt ships such as Juan Carlos and even the Karel Doorman.
You get what you pay for but you could see quite a few operating small numbers of F-35's - at least for a short while - which maybe all you need. Horses for courses
Agree that we will see a variety of interesting aviation capable ships, and a few smaller carriers operating F-35B's. Beside the US and UK operating the B as STOVL, I would not be surprised with Japan getting a few B's for those nifty new "destroyers".
Will the ski jump on Canberra prove too tempting not to use?
Looks like Italy is making moves towards making their STOVL carrier B capable but politics seem to continue on the A/B mix, while Spain seems to be biding their time.
I was more commenting that the two South American countries that have operated carriers will likely be out of the fixed wing carrier borne business entirely. Doubt they could afford the F-35B, or a new or second hand carrier and air-wing of any type.
