J-20 5th Gen Fighter Thread VIII

[taxiya]

I'm not sure I would be 100% sure about putting the J-20 above the F-35 though. J-20 being larger also means (if similar stealth methods are employed) that it also has a larger RCS. Also, bigger radar doesn't mean it's better, there's other things like software that are just as import.

The two does not have similar degree of stealth method used. One thing of stealth is the facade to be flat so EM waves bounce off to other directions. F-35 has a bumpy under belly like a conventional aircraft. Being larger isn't nacessarlity a negative thing for stealth, example is B-2. It is also worth to note that F-35 was not designed to match the level of stealthness as F-22 from its inception and will never reach that level.

Bigger radar is certainly better if others are equal such as SW. And no need to argue about F-35 has any advantage in radar software, software is nothing except the algorithm which US doesn't have edges. The mobile network essentially shares the same knowledge and exprience with radar signal processing, guess who is the leader in the area.

In that case the F-22 has RCS tradeoffs too, like the splitter plate and likely less advanced RAM.

Last part of this article suggests differently:
"Hostage caused a stir in late spring when, in press interviews, he said the F-35 would be stealthier than the F-22, its larger USAF stablemate."
Supported by the F-35 Program Officer:
"“I would say that General Hostage … is accurate in his statement about the simple stealthiness of the F-35 [with regard] to other airplanes,” Bogdan said in the interview."
There are other sources indicating the same thing. I am surprised the fact that the F-35 probably has a lower RCS than the F-22 in at least some aspects isn't common knowledge by now, even considering the lack of more specific information.

These things are all classified, so we don't know. But just looking at the aircraft, it validates the view that F-22 was designed to be LO across all aspect. You can see the work they do to conceal the nozzles that just aren't applied on F-35s.

Is it possible that F-35 has lower frontal RCS in certain aspects? of course. And since F-22 is not being upgraded with the same thermal management system that F-35 will be, there is just no way it can have the same EW suite that F-35 does.

I mean if you are USAF right now and have F-35 platform as your main aircraft for next 20 years and it has less range/loiter time than J-20 as well as less interior space and don't have major stealth advantage. This is troubling time for US military

Unlike the F-35, the F-22 also doesn't have DSI, the lack of which may expose more heat signature of the engine faces from frontal view, despite the S-duct.

The premature retirement plan, announced by USAF a couple of years ago, as well as substantially cutting orders while simultaneously ordering more F-15's and F-16's - the very aircrafts the F-22 was intended to replace - indicates a major flaw in the system. For reference, USAF currently has 100+ F-15EX on order. The excuse given at the time was that US rivals do not have anything to match the F-22. But if J-20 is a rival (which it is), then USAF should've restarted acquiring more F-22's... which it didn't. That, again, points to a major shortcoming in the F-22.

For what it's worth the F-22 tooling was taken out of the plant. And that factory is now building F-35s. So they can't build them even if they wanted to.

Had they exported them to Japan and Australia as some wanted the line might still be operational and more could have been ordered. The only reason the F-15 line is still available is due to sales to the Middle East.

Can someone explain what does this mean? I don't know chinese.

Neither do I but I would like to work through the reasoning and any Chinese-speaker can correct me.

2323 refers to % of annual output, i.e. Q1 20% Q2 30% Q3 20% Q4 30%. This was mentioned a while back.

They use the phrase "双过半" which from

(MTL'd) indicates completion of over 50% of two closely related indicators. One of the examples is planned production and actual production.

So given it's the beginning of the 2nd half of the year, it sounds like they're celebrating exceeding the planned (2+3) production in the first half. If they had planned to produce (random number) 100 J-20s, this would mean they already produced more than 50 in the first half.

Ayi claims 57 airframes in a quote post (114 for 2024)
To mislead us? maybe, But again 100+ was expected this year

Won't be surprised if that turns to be true

So the claim is 57 airframes in the first 6 months ?
What is the trackrecord of this guy if any ?
