Yes. But why would the PLAAF place such an order?
They should want the J-20 instead of a larger number of additional J-10s
I think you’re both missing that there are many situations where quantity is its own quality, especially in doctrines and strategies that emphasize network centric combat.you are absolutely right if PLAAF has no budget limit .... but unfortunately PLAAF do have budget limit
I am sure you are aware that J-20 is a very expensive, like ~2-3x of J-10B/C
That said, I do think the PLAAF might end up procuring more stealth fighters than some of original low end estimates, but it may not be the J-20.
