There is no public funding for it, meaning there has been no public announcement of funding for it. If they are funding it secretly, that's something we have no evidence for and no reason to believe because why would they need to hold that a secret? Why would SAC refuse assessment of their fighter? Are they trying to screw themselves out of investment funds and development opportunity? Makes no sense. It is outside of the realm of reasonable probability that SAC would refuse that. It's 99% likely that SAC invited everyone they could to see what they've got and potentially invest. Then, if there's no investment, at least none publicly, then why? I think the most logical reason is because it wasn't impressive. Could we think of other possibilities? Sure we could; but I think this here is the biggest probability.
Sure, it could be funded in the future; I never said that's not possible. Maybe they assessed it, then said there were major issues, so SAC made V2 and showed them an improved version and they said there were still major concerns so SAC would pass their test with V3 when it's ready. Might happen; I can't tell the future. But taking this long, to me, isn't a good sign.
I understand that, and in almost every post, I acknowledged the possibility of secret funding for J-31. But there is no public funding for it in the sense that neither PLAAF nor PLAN has publicly taken the project under their funding like they would if they were proud of it. And I don't see any reason for them to keep funding secret. So I'm leaning heavily towards no funding.
