But why respond to increased F-35 numbers with the J-35A? Why not just build more J-20s? Scaling up an existing type should be more cost effective than investing in a whole new type wouldn't it?
Further more, scaling up production # on exist type like J-20 is much faster and cost effective than introducing the new type.
It's very easy to suggest "muh, just scale up/expand" without considering the already present capacity constrains facing Chengdu AC.
Just as I've previously mentioned - Per the Guancha Trios, Chengdu AC is already reaching its limits with the present J-20 production rate of ~100 units per year. How are else you going to wring even more water out of a nearly dry towel? That's yet to include the fact that there are also other concurrent, similarly-important projects in Chengdu AC, including but certainly not limited to the J-36.
If anything - You're looking at Chengdu AC being the only one shouldering the task of building up China's 5th-gen fighter fleet - Until now. If I'm Chengdu, I'd be more happy that Shenyang has finally joined in the workspace to share my burden.
J-35 is not necessarily cheaper than J-20 given dual engines and same level of avionic.
6th Gen will be entering service in 10 years too.
If you're talking about the PLAN's J-35 - Sure, given how the PLAN demands the top tier stuffs for their frontline units, which is competely understandable as they are always expected to be the first ones to face against the enemy onslaught head-on.
But this isn't the case for the PLAAF's J-35A, which is a slightly tuned-down version of the J-35. It will not feature all the top-tier features and capabilities as those found on the J-35s, but they're good enough for the PLAAF for facing off against the present and expected threats on the region to induct the J-35A in larger numbers than the PLAN could/need with the J-35.
Let's just say that while the J-35A could be being slightly (if not generally) superior to the F-35, the J-35A might only be largely equivalent to the F-35 in terms of performances and capabilities, or perhaps even slightly inferior to the F-35 in certain aspects. I certainly failed to see how a J-35A is going to cost really close to the J-35, let alone being anywhere close to the J-20/A/S.
It could sound like a bad thing - But remember that if the PLAAF is capable of flooding against the opposing side's F-35 fleets with their own large J-35A fleets + supported by the J-20/A/S fleets, then that's a much greater plus to the overall PLA warfighting effort and a greatly worthwhile investment, that some people here seems rather struggling/reluctant to comprehend.
Furthermore, just as I've explained in the J-35 thread regarding the J-XDSH+J-35 and J-35+J-15 discussions - Not every mission requires the larger and heavier J-20 to do the job. The J-35A fits the need for these types of tasks well, whlist able to complement the J-20/A/Ss in the overall grand scheme of things.
