I actually am hoping for simulated air combats between the J-20 and Su-30SM. Since the Su-30SM is pretty much a MKI we’ll be able to figure out whether BS Dhanoa’s “several kilometers away” claim is factual .
p.s. Who am I kidding. A J-20 flown by a kid with less than 100 hours on the plane has a 17:0 kill ratio against a flanker.
Yeah don't even joke about that lol, the claim itself is not even worth substantiating or entertaining in the first place.
I say this only partly tongue-in-cheek, but I don't think the smell test applies to the US. If it did, the Zumwalt wouldn't have survived the first design meeting.
Zumwalt sort of made sense at the time, it died from a thousand independent incompetent cuts.
For the US flying 5th gens with the IAF at present or in the recent past doesn't make sense either way.
Anyway, I see what you're getting at that this requires a significant degree of trust. I think that trust is there between China and Russia and will remain so for the foreseeable future (for at least as long as the J-20 remains sensitive technology and probably long after it's become obsolete). I would also agree that even given that trust the PLAAF would still want to hold its cards close to its chest, except for one thing: I think it also wants to show off. In fact, I think it's dying to do it.
Think about it, since 1949 until the Sino-Soviet split, the USSR was the richer, bigger, stronger, and better-looking older brother. Even after the split, Russia remained the dominant power in the Communist bloc - the admiration (or envy) was still there, it's just that added to it there was now acrimony.
Decades later and fortunes have changed. China is now the one, as the kids say, ballin'. You bet it wants to invite Russia over to the new house to get a look at all the new toys and drive the Lambo around! This kind of flex is a dream come true for all the old-timer generals in the PLA. That's why we hear reports of Russian soldiers getting up close and personal with all the new gear and the J-20 participating.
Whether the PLA is now the rich kid on the block relative to Russia or not is irrelevant to my reasoning...
All that matters here is how much the PLA trusts their Russian counter parts in terms of giving them exposure to arguably their most important and sensitive aircraft in service at present.
If the PLA were doing this based on arrogance or a sense of superiority, then frankly I'd be somewhat concerned on their behalf.
