Interesting, I imagine you're warming relations between the UK and Argentina in your AU? Otherwise I can't really see the export of what will still be pretty current combat aircraft (Typhoon -containing quite a lot of British systems) to Argentina without some sort of agreement being reached about the Falklands. Also the hawk you have illustrated isn't a T.2 but a T.1 . Other than that it seems pretty plausible.
ETA: Nevermind, I missed the Chilean AF tab
