Harry,
Surface-to air-missiles, Mate. Typhoon have reasonable air-to-air or anti-aircraft missiles. I agree that Patriot might not be a bad addition, but I probably wouldn't put them on West Falkland, that would just mean a detour to stay outside the MEZ. Better at more local air denfence, I think.
Of course, we'd have to make sure they had the Mode 4 sorted out!
Then we need some decent air-to-surface and surface-to-surface hardware to ward of the naval armada.
