F-16, Sukhois, F-15, F-18, F-35, KFX.....seriously?
Better to just cut it to F-16, KFX and F-35
F-16 : Already large quantity of them, established infrastructure, common spareparts and airframe availability, upgrade package is readiliy available
KFX : Strategic medium-fighter program that could both benefit the air force by it's own and as importantly to the defense industry, no matter how much of a share the manufacturing and design PTDI will do, it'll still be vaulable and not to mention providing us with competitive advantage of advanced fighters that we can maintain by ourselves, reducing our reliance on constant imports.
Really in testing time anyone would think that foreign countries could maintain these weapons as good as if we could master the technology by ourselves? sounds like people are amnesiac of parts embargo that hit us back then well? these people forbid us from using weapons when we need them the most! how ridiculous that is! idk if you guys insist that we should stay being consumer all of our existence so be it, but remember that no strong country in this world cannot manufacture it's own weapons.
F-35 : Nuff said, already a potential customer and that strengthening terms with US and Australia will eventually leads us to F-35 program, but for me it should be beneficial to both the F-16 and KFX program that we have by then, again not just passive consumer of traded goods that only makes us dependent on the supplier.
