The below pictures which recently surfaced and were posted by our dear friend wangrong a few pages before in this thread speaks volume about the system PAF is gonna have. If we go by this model, it means we are not getting a linear shaped radar on the Chinese platform, rather a dome version. And the aircraft which came to Chaklala was also a dome version not the linear shaped one, so both these things give credibility to the notion that we will not be getting a KJ200 system, but a miniature version of the radar or AEW&C being used on the Chinese KJ2000 (IL76/78).
So PAF most probably would be using the 4 Saab 2000 platform Erieye Linear Shaped Radar AEW&C systems and 4 dome shaped radar Chinese AEW&C on a Chinese Y-8 platform & not the Linear shaped KJ200.
