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.
"Totally effective," is doubtful.
But yes, going forwards, networked and distributed sensor/shooter platforms including a large number of attritible+distributed UCAVs will likely end up being one of the adaptations in which air forces (with the requisite technology and industry base) will respond to stealth aircraft.
The idea is that UCAVs ultimately are less valuable than a manned fighter (stealth or not), and they are able to operate more riskier than your manned aircraft, by operating more forwards of your manned fighters, by actively emitting more often and more intensely to look for the enemy, both of which will hopefully offer better situational awareness and better first look-first shoot options, than a formation of manned fighters alone which would have less freedom to operate as aggressively in terms of positioning and emissions.
The fact that the UCAVs would be more distributed in offering additional sensor capacity and weapons magazines, all being semi-autonomous and where the tactical decision making is enabled by line of sight datalinks via manned fighters operating "behind the frontlines," means your manned fighter + UCAV formation should have categorically superior sensor/SA, positioning and weapons options than an opfor formation if it is made up of only manned fighters. Not to mention your force being more attritible.
