Current cope by Chinese liberals/NAFOs are pretty creative. You’d think that they’d just dismiss the whole thing as SeeSeePee propaganda but no… Get a load of this — “F-35 and F-22 got locked on by Chinese jets on purpose because they are gathering flight envelope data for the CCAs…”
Not necessarily totally cope.
My view is that peacetime intercepts are a really bad read on capabilities. If DACTs are to be taken with a pinch of salt due to lopsided scenarios and asymmetric ROEs, then peacetime intercepts need to taken with a whole bag of salt.
A sub tails a ship for days. A pilot gets to within stone throw distance of a OPFOR plane. A soldier stands nose to nose with the "enemy" across a LOC ... all these scenarios can only possibly occur during peacetime and only because one or more parties are simply told to ease off and not respond/retaliate.
I've been involved in opposed Exercises as light infantry. Just like DACT, even these come with some form of scripting to enable the exercise to achieve set objectives. Soldiers being soldiers, men being men, no one likes to roll over and play dead. So everybody plays fast and loose and pushes the ROE and exercise parameters as far as we can. Sure as night follows days, this builds frustration and ultimately results in actual coming to blows when Blue force comes within clubbing distance of Red forces. Now imagine this where parties are not even on the same side and are armed with live shots. Scary.
Infantry exercise may not be quite the same as air intercepts but you can imagine the potential for an international incident if one side does not back off and both sides does not want to "lose" face/bragging rights.
(though I wouldn't mind a F-35/22 being forced to land on Hainan and being sent back to the US in cut segments, preferably with no loss of life like the P-8 incident)
Ultimately, the ability of of a J-11 to outmaneuver a 5th gen F series means zero given the nature of modern Air-to-Air combat. BVR abilities means you are unlikely to merge. Even if you do merge, HOB LOAL abilities means that WVR combat is also less about getting on someone's six.
I wouldn't read too much into this other than for some internet bragging rights.
