Which is precisely what has surprised me. This could mean two things. Either the Rafale, to put it bluntly, truly is just as overhyped as it is overpriced; or China has made some insane advancements in radar and electronic warfare tech to the point that even the the supposed 'best' 4.5 gen that the West had to offer (not that I agree, I think the Super Hornet or Block 70 F-16 are superior to the Rafale) couldn't really measure up to it. And the fact that both can be true is even more surprising, though I'm leaning toward the latter.
Which is actually scary when you think about it. If China's (arguably) 4th or 5th best fighter jet can do this; imagine the capabilities of its more capable fighters like the modernized 4.5 gen Flankers, or the J-20/A/S, or the J-35 or even the upcoming sixth gen airframes especially armed with more potent missiles like the PL-17. This was a massive, massive wake up call for every single defense analyst.
