Chinese purchase of Su-35

b787, that's why we suspect you're mig-29, because your assertions about the Irbis-E system are so illogical. The Irbis-E has 400 km detection range vs a 3 m^2 RCs. This translates to 303 km detection range against 1m^2, so essentially, the superiority of the Irbis-E exists only in advertising. It is, however, competitive with the Eurofighter and the Rafale, which either have PESA, medium-aperture radars, or both.

90 km detection range vs .01 m^2 = 284 detection range, when Chinese AESA and presumably US AESA can detect 400 km on an aperture the size of a flanker. Likewise, as a PESA, it is more susceptible to jamming.

Dispassionately, look, the Su-35 has advantages over the J-11D, namely in its range and maneuverability. The J-11D, on the other hand, has advantages over the Su-35, namely in its avionics. Is this somehow unfair to either the Chinese or the Russians that we highlight the advantages of both aircraft?

The Rafale has the RBE2 AESA radar with roughly ~1000 T/R modules (which I suspect would provide it with roughly the same league of capabilities as the AESA aboard the J-10C). The Eurofighter would soon sport the CAPTOR AESA radar as well.

Yes, and CAESAR is an AESA designed for the Eurofighter. When it comes to radar, however, the Eurofighters are retrograde. It's a roughly Super Hornet sized aircraft that has an AESA about the size of an F-16. The Eurofighter, on the other hand, is a 100 million plane, with a radar aperture only comparable to the F-35 and smaller than both the Flankers and the Eagle. The J-10C, to its credit, has a radar aperture roughly the size of a F-35 or Super Hornet; it's an aircraft between the F-16 and F-18 in weight class, but has an F-18 sized radar.

@taxiya: except that the PLA2nd Artillery drove its ICBMs on parade, so we have information suggesting the existence of the Chinese ICBM force. Moreover, Chinese nuclear tests are a matter of public record.

Whereas, despite knowing about composite improvements to the J-11Ds, we've seen no data indicating the existence of fuel tank expansion. In the Su-35 case, parts of its tailfins were hollowed out to place fuel tanks there. There is no corresponding information for the J-11D.
well, continue pretending to be you, I would say "I only see a giant truck carrying a canister running around, I have no information of it actually carrying a nuke".

I don't intend to nip-pick your words, but I'd rather want to remind you to be cautious of the "has/has not information" thing as the natural of PLA/information is very different from the west and Russia.

OT but I must say that you are not alone in suspecting that in ways of many things.

Your logical deduction is that "since the J-11D uses composites, I want the J-11D to be superior to the Su-35 in as many ways as possible, so I'm going to assume the composites lead to an expanded fuel tank". The evidence is not sufficient to prove that, whereas in other cases, we have rumors, even official PLA announcements. A J-11E may have increased internal fuel capacity, or even CFT, but why is that important? It's a 3rd/4th gen aircraft when the latest and greatest Chinese aircraft are 4th/5th.

tell me what is the difference in the electromagnetic waves emitted by an AESA and a PESA? are they not the same Electromagnetic radiation?

The difference has something to do with the way the radar process the information or the way it emits it?
Do both types of radars emit electromagnetic waves upon the laws of Maxwell or AESA radars use other type of physics?

why IRBIS can have such range?

Your arguments are just bad. You're doing a strawman argument because IRBIS-E is PESA, not AESA, when even the Russians have their own AESA technology. The advantage of AESA over PESA is that AESA tends to be more efficient; it loses less energy because its generating elements are inside each module, instead of connected to a central magnetron generating transmission losses. Likewise, because each module has its own emitter, its detection range scales better with aperture size than PESA systems.

Not sure if serious?
