Norway showed that JSF's combination of capability, acquisition price and support costs are unbeatable.
If, that is:
You accept what the LockMart PowerPoints say about its capability;
You believe that the acquisition costs cited now are the price that you'll pay when it comes time to sign a contract;
and that the support costs are what you'll really see in service, once you are totally committed to reliance on a monopoly supplier;
and Santa, the Tooth Fairy and the Easter Bunny not only exist, but are ready to sign up for JSF as well.
The first problem for the jet's competitors is that the customers can and will (quite rightly) ask for real numbers. If you want to know how much a Gripen NG will cost per flying hour, you can get a pretty good idea from the Czechs, coupled with US Navy data on the F414. The price of a Typhoon is there in black and white as part of a contract.
The second problem for the competition, in terms of capabilities, is that stealth allows LMT to close any public argument with "I could tell you, but then I'd have to kill you."
