The bird just looks outdated with that rotating dome. Now is the era of electronically scanned arrays. I believe it was revealed on this forum that one of the aircraft had an ESA installed recently, so they are trying to make it fit. But it is well known how Chinese create compromises to achieve certain performance parameters. So it would be interesting to know how much performance upgrade potential is there. Also when we got them, the goal was to not get marooned if sanctions kick in during hostilities and Erieyes are affected. I hope upcoming indigenous solutions rectify these problems.You are very close..
