Y-8J always remind me of Nimrod and its Skymaster radar.
We have something like that with AEW UAV I think.
Aside from that, KJ-500 operates in the L band. If KJ-600 is anything like E-2D, it would be operating in the upper range of UHF band. All of which should have fairly long detection range against F-35.
Probably not for quite some time. Human intervention cannot be excluded at times.A little off...
I wonder when UAVs will takeover AWACS role entirely. With future heavy UAVs with long range and endurance, powerful enough engines to support powerful equipment, fast secured data links, should eliminate need for any onboard personnel for data processing.
