of course there is no problem with J-10 stands in PLAAF right now, but in the future, it's hard to tell, especially your enemy start to ramp up their size of F-35 or KF-21 or something else.
also speaking of cost, what's the cost of losing a war?
will i save like 500-1000 million on J-10, and have 500 less J-16 or J-20 than losing a war outside the 1st island chain or in south china sea? or pay that amount and win that war?
I have no idea what you're trying to argue here.
Obviously it would be better for the PLA the faster they can change to an all 5th gen (and beyond) fleet, which I wrote in my previous post.
But this entire discussion has been about why it makes sense for the PLA to buy more J-20s (and J-16s) and buy less J-10s.
What tphuang has argued over the last few pages, is to explain why among the current fighters in active production (J-20, J-16, J-10C), that it would make sense that they're not buying as many J-10Cs, and why it makes sense to buy more J-20s and J-16s.
