KC-390 plus Gripen NG would make a good team!
It is all academic. Given the superior combat radius of the Typhoon vs the Gripen, the KC 390s could be shot down before the Gripens had taken on enough fuel to reach the Falkands, leaving the Argie Gripens feet wet and short of fuel. Or just shoot down the Gripens. Or both.
Gripen combat radius = 432 nm
Typhoon combat radius = 769 nm
Buenos Aires to Stanley = 1,025 nm
Nuff said!
