I don't find him anywhere near as informative on military stuff as Shilao, but his podcast made some useful point too. He mentioned that he has a contact flying either F-22/35, who he contacted to ask about this encounter. Basically, his contact said that they are typically very careful when encountering another aircraft of same generation, because they don't want to give away secrets about how they operate it and the capabilities of their aircraft. And they see the same thing from PLA side of things. He also said that other pilots have experience scenario where PLAAF aircraft spotted them first and they couldn't spot PLAAF aircraft for a period of time. It seemed like in both cases, both PLAAF and USAF aircraft would be given some advanced early warning that they were approaching another stealth aircraft.

Now, I don't know exactly how much Luneberg lens amplifies RCS of a stealth aircraft, but I get the impression that it doesn't amplify return to the level of a 4th generation aircraft. Please correct me if I'm wrong here.

Also, they talked about the comment over KJ-500 providing targeting data and guiding long range missiles. They mentioned that the target aircraft probably got beamed on by KJ-500 for a long period of time. I obviously don't know which aircraft is getting locked on by KJ-500 at long range, but presumably beaming at a tight window gives longer range and accuracy than doing full scan. And the advantage of having multiple KJ-500 in the air is that the target aircraft cannot simply turn itself so that the direction with the lowest RCS (let's say frontal) faces that KJ-500. In that case, the side profile would be more trackable from longer range. Especially with L-band radar that I think KJ-500 is carrying.

If we consider that Gen Wilsbach's comment that E-7 can help shooters in detecting J-20 (+ the out of no where praise of KJ-500 in kill chain), it probably means that KJ-500 is legitimately helping PLAAF shooters to find/track F-35 at longer range.

Other have speculated that Wilsbach comment about PLAAF command and control indicates that USAF is impressed at how quickly PLAAF was able to scramble J-20 over to meet F-35. In reality, I think they are more likely just sending over whichever aircraft happens to be closest to F-35.

No offense but some of the stuff Xi Yazhou spouts comes across as Chinese version of Jai Hind. He bashed American gear too much.

As a guy who know Xi Yazhou and Shilao personally I could say the difference between Xi and Shilao is kind of different market positioning but not personality (and yes, personality involves too). Xi is positioned as a over the top guy and Shi is more nuanced.

How accurate are either of them do you know? Are they just getting information through a grapevine of hearsay or are they vetting information thoroughly? I’m asking because I’ve seen both make claims before that seem a bit questionable like two years ago when one of them (I think shilao) said the WS-15 was already flying on a test bed.

Any reason the Guizhou factory couldn't churn out J-20s as well?


Since changing a product on an established factory cannot be done over night … but anyway, do we have confirmation that Guizhou is already producing J-10C? AFAIK it is just a rumour Yet.

No stealth fighter has RAM applied all over the aircraft. That would be way too heavy. If I am not mistaken they are only applied to areas with stronger than usual radar returns. That said, control surfaces are honey combed internally to reduce radar returns.



The articles themselves are usually pretty good but the comments section… Sweet lord. They probably don’t want to upset the “fan base”.

That said I expect an article from RUSI pretty soon, and another one from Air Force Academy.
I thought F-35 and F-22 have RAM all over? It seems like the case visually and based on documentation.

Some people are claiming J-20 only has RAM at the edges.

They have a lot of sources inside the military, and a lot of things can only be talked between friends even only offline. In the show only so much can be said, even delibrately misleading. Actually I knew something that I know should not be posted anywhere.

J-20, F-35 and F-22 have RAM all over. Only areas that are physically impossible to cover with RAM, like various antenna apertures, are not covered. However, RAM type and thickness are not uniform throughout. Critical areas like wing edges and intakes will be covered with thicker RAM.
