J-20... The New Generation Fighter II

[bladerunner]

Wow isn't it a bit early to start giving out real numbers? Espicially if we don't know what kind of RCS J-20 has in the first place.

I'm sure the PLAAF already have tactics for use against F-22s in place, even if it's just to survive the initial wave of BVRAAMs. It will be interesting to see the J-20 vs J-10s and J-11s.

You have a point however as I said in my earlier post, it was just an example of the type of response one finds on Western forums,I guess its so we can still sleep easy at nights and anyway another thing, it was all stealth until the Chinese came along with their effort (J-20) and now the talk is about superior sensors radars aa missiles etc, chuckle chuckle.
Bty some poster has come up to a russianlink providing guesstimates off the RCS off the J-20, never read it though.

Considering China is fielding the biggest type of airborne AESA radar out there, I would say China is actually ahead in stealth-detecting capabilities.

yip, chuckle chuckle,that would not surprise me and then over time the other side builds a better one and so on and so forth, and in the end I wouldn't be surprised if they cancel each other out, so what happens after that?

Actually, if anything I'd say Russia/Europe is still a step ahead of everyone in stealth detection. Most of their means are via IRSTs, high-powered Thermal cameras.

shows clearly that even the best Stealth crafts of today can be easily tracked by a simple FLIR camera. European advances in the IRST industry, including the adaptations of QWIPs, will allow a F-22 to be tracked far from when you can see it on radar (due to the F-22's VLO, a Su-35 will track it from about 40 km.) A High-powered IRST equipped with QWIPs will probably be able to detect a non-afterburning F-22, T-50, and even the J-20 from over 50 km, maybe 70-90 km away. After that, one can whack it with a BVR-IR guided missile.

Also, the simple fact that China is fielding the largest AESA doesn't mean they can adapt AESAs for smaller applications, for example, Fighter radars.

An analogy is that Russia is fielding one of the largest OTH radars but that doesn't mean they have the best OTH technology for their ships.

So it looks like J-20 has a single long bay for anti-ship missile or a very long range AWACS killing missile. It then has two side bays (opening out to the side) for medium-range and short-range air-to-air missiles. I guess like PL-21?

I thought the problem right now is still currently China can't miniaturize the AESA from shipborne version down to fighter size - they manage to shrink it down for the KJ-2000 AWAC, but the power requirement is probably too enormous for the size of J-20?

One of the greatest challenges with producing AESA radars is getting out the individual T/R modules. With the KJ-2000, KJ-200 and 052C (among a few others) they've shown they can mass produce them therefore there shoudlnt' be a real concise "problem" as such.
And they didn't shrink the 052Cs aesa down to KJ-2000 -- the KJ-2000s radar is from the Israeli Phalcon which they orignally bought, but basically had to produce by themselves (due to US inteference).

Of course there might be challenges, maybe some in terms of the bands the varying radars operate in or such but that's out of my league.
Also, there's no reason for fighter radars to be as powerful as AWACs -- if so then that would delete one of the primary reasons for AWACs to exist in the first place.

The weapons bay will probably be like the F-22s: one single, wide bay with two smaller ones for SRAAMs. We haven't got pictures of the J-20s bay from the prototypes yet either.

From the pictures though, it's obvious no contemporary Chinese or even foreign AShM can fit into the J-20s weapon bays. The central weapon bay may be a fraction longer than the F-22s, but may not be much deeper.
And China doesn't have any anti AWACs missile we know of -- don't get ahead of yourself -- unless you mean like PL-21... Which incidentally won't be in the side bays, but would be held in the central bays instead. the space for the side bays, if there are any, would be reserved for SRAAMs like PL-10 and is far too small to hold MRAAMs or LRAAMs.

If anyone can post some pics of the j-20 prototype cockpit please? there's something special about it.

thnx in advance!

You are completely wrong. The F-22 does not have one long bay. It has two on the bottom and two on the sides.

J-20 has one long bay, that should tell you its payload is at least F-35 class, not F-22 class.

Oh the irony.... First, he said the F-22 had one wide bay and two smaller ones, so that's correct. Second, he said that the J-20 is probably just like that, and judging by photos it appears that he's also correct on that account.
