I think the air combats were all WVR, because at that time, J-10 was not yet equipped with PL-12. So, it was most likely J-10 with PL-8/PL-11 vs flankers with R-27/R-73.Originally Posted by ajaybhutani
The problem with su-27/su-30mkk is that its radar is terrible. So, it would not do much better against J-10 in BVR than in WVR. It got N001VEP for su-30mkk, which was still using a twist-cassegrain antenna. And it could only do two concurrent engagements with R-77. The su-27s uses the N001E radar, which is more archaic and can't even do multiple engagements. Although they might have been modified to R-77 capable. The proposed Pero phased array antenna upgrade would've made it better, but China did not opt for it. Actually, I think the issue is not that the Russians couldn't offer China better radar, but it was that China was not looking for an air superiority fighter when it got mkk.
I'm only talking about A2A. Su-30mkk was bought for more attacking roles, so their A2G capability is superior to J-10. The baseline flankers do not have any A2G capability.
