What's interesting with combined sensor nodes behind Chinese attempts at fighting adversary VLO is the inherent capability of small, low RCS stealth UAVs in building enough resolution on adversary VLO for CEC to engage. Somewhere between the J-20 and the AWACS will probably be a lot of J-16s and J-10s. Adversary will attempt to do the same to erode the line though. Small stealthy UAVs can get much closer to F-22/F-35s than a J-20 could.
Wasn't there a leaked paper and hints from CAS or someone working somewhere else that they've developed a networked solution which is totally effective against stealth platforms but relatively complex and delicate since it relies on dozens of sensory nodes to fuse target information.
