It is obvious that the regional superpowers are gaining a much stronger foothold into SE Asia with them buying Su 30s. (I saw this machine at Singapore airshow and it is a much better platform than the RAAFs FA18). Since the RAAF are prematurely retiring the F111, with persistent profiles the current fleet of 80 to 100 hornets will need 12 to 15 A330 tankers to support them against this superior fighter. - for the doubters - this is obviously due to the realistic nature of network centric warfare!!
