why PLAAF more choose the obsolete radar? Are now they modified all radar their flanker fleet?


The radar itself was developed around the eighties, and reflects the technology level then (e.g. Intel 8080/8088 processor). The development level of the Russian processors for the N001E radar is about that. At the time when the Su-27SK was first ordered, which is 1992, all this does not seem that old.

The modified radars the PLAAF uses now has a modular subsystem that is powered by an 486 class processor(s). This subsystem handles the R-77.

the original computer for SU-27SK able to performed a very low 170,000 ccomputation/sec.,by contrast SU-30mkk main computer,according to Chinese aviation mag. able run 1 billion /sec.

Let me get this clear. There are no main computers in the system. Radar systems are distributed processing systems, which means they're built of not one single computer, but many small ones talking to each other through a bus. Each small computer handles a subsytem of their own.

The system on the Su-30MKK, called the N001VEP, is actually two new subsystems added on top of the old N001E used on the Su-27SK. Thus, its really hacks upon an old system. The first new subsystem adds R-77 capability, though this system may also include Kh-31A capability as well (both are radar guided missiles, remember that antiship missiles are also radar guided. The second subsystem adds precision guided munitions capability. Its basically built around a fiberoptic optical-TV channel and it is used for the TV and laser guided weapons on the Su-30MKK. This is the part of the Su-30MKK subsystem that is most advanced.

What the J-11s have is the first subsystem (SUV-V). The Su-27SKM upgrade package includes both subsystems, but China did not opt for the second system that supports TV and laser PGMs. Otherwise, the J-11s would have full SKM capability instead of being half way. By having so, the planes would be single seat equivalents of the Su-30MKK.

To make it clear this is how it works again.

N001E (basic radar)

N001E + R-77 subsystem. Used in J-11s and last batch Su-27UBK.

N001E + R-77 subsystem + PGM subsystem -> Su-30MKK

Now the R-77 subsystem is modified further adding sea search and targeting modes for Kh-31A support. ---> Su-30MK2.

The whole point is that the old systems and computers are still there, but they have been added with new systems and computers that work along side.

Analysis: China eyes new Russian tech

by Andrei Chang
Hong Kong (UPI) Nov 23, 2007
A Chinese military source based in Beijing has said the People's Liberation Army Air Force is negotiating with the Russian Sukhoi Aircraft Company on three new projects.
Military observers based in Moscow and Beijing say they believe the recent nadir of military cooperation between China and Russia is only temporary. China will have to rely on Russia to develop its military technologies, as Beijing has no other alternative.

The first new project involves Su-33 shipborne fighters. Experts from the Russian aviation industry are convinced that China is about to start the construction of an aircraft carrier.

"Up to the present, on the issue of the Su-33, China and Sukhoi have had three rounds of negotiations and have reached some agreement," said the source.

Nonetheless, he did not disclose what specific progress has been made in the negotiations, merely confirming that additional rounds of talks will be held. A high-level source from Sukhoi confirmed his company is most interested in discovering whether the Chinese want to purchase whole Su-33 fighters or only require Su-33 parts, and whether they will request the transfer of production technology or design blueprints.

Other sources from the Chinese military industry said that several plans were involved in the negotiations on the Su-33. One of them is that China will buy a small number of Su-33, say 10 to 24, and later request that production technologies be transferred. However, the Chinese strategy is to use some of the Su-33 technology to develop their own shipborne fighter based on the J-11B assembled domestically.

The second project under negotiation involves the newest Su-35 fighter. At the MAKS 2007 International Aviation and Space Salon held at the Zhukovsky Air Base near Moscow in August, Chinese delegates took photos and videos of the Su-35 virtually every day.

"Several Chinese delegations have visited Sukhoi and raised technical questions," the Sukhoi company representative said. He said the two sides have reached a consensus and are now working on export plans.

"At least in the foreseeable future, China's indigenous aviation technologies will not be able to produce combat aircraft similar to the Su-35," he said. "Our attitude on this issue is the same as the case of the Su-33; that is, we are only interested in exporting whole Su-35s. This is not what the Chinese delegates hoped for. They hoped to import only certain subsystems, for instance the radar systems or the engines."

The third project concerns the PLA Navy's plan to import more Su-30MK2 fighters, or upgraded variants of the aircraft. No progress has been made on this as yet, however. A plan for China to import Su-30MK3 fighters, which was negotiated earlier, has not been carried out so far.

The possibility that the navy will continue importing Su-30MK2s or Su-30MK3s appears slim, mainly because it has already started to receive China-made JH-7A fighters. Meanwhile, the upgrade of the J-11B fighter aircraft has been very comprehensive. The fighter is now capable of launching precision attacks on battleships, and can basically meet the combat requirements of the navy fleet. China may not resume the import of Su-30MK2s unless the cost of the J-11B remains too high or comes close to the cost of the Su-30MK2.

Is there any possibility that the PLA Air Force may upgrade its existing Su-30MK2s and J-11s, or the Indian Air Force's Su-30MKIs, to a combat platform close to the Su-35 standard?

Yury Bely, a general designer at Russia's NIIP Radar Design Bureau, agreed to discuss the question. "It is impossible to import the Su-35's radar system only," he said. Bely stressed that it would be more feasible to import brand new Su-35s than to try upgrading the Su-30MK2.

The Su-35 is equipped with the H035 passive phased array radar system, which has extremely powerful detection capability, Bely pointed out. The average output power of this radar is 5 kW, with peak output at 20 kW; thus the output power of the Su-30MKI and Su-30MK2 would be insufficient. When the H035 radar was tested on Su-30MK No. 503, the detection range was as far as 290 kilometers with 1 kW power output, he said.

Can anyone help with an identification ???

1. picture I would say a J-11A or even B with a strange missile under the left wing.

2. picture looks more like a Su-30MKK with its taller fins but maybe the same missile ???

--> So first of all do You think both ac are the same and if YES, what the heck ... ???? ... maybe the J-11BS ??

Cheers, Deino

Its too blurry or lack high resolution detail to make out the missile, or the J-11BS vs. Su-30MKK characteristics.

Hmmm ... I'm not sure and therefore tried to enlarge and sharpen them.
Iin the firts picture we can clearly see the grey corners of the tail and strange nose-marking suggesting a Chinese Flanker - also it looks yellow but that could be due to lighting conditions and also if the radome is black ???. Quite strange it seems as the wing has one additional pylon.
For the second picture I would say it has the larger squared fins (IMO) ... so are both aircraft the same or not ???

Cheers, Deino :confused:

Corner patches on the elevators are also found in the MKK, but not in the Su-27SK, so having the dark corner patches can either mean MKK or J-11. If the wing has one additional pylon it can be an MKK but who knows if the J-11BS has been modified as well. Yellow color would lean it to a brand new J-11 and so will a black nose. The MKK's rear fins are not larger than that of the UBK, just squared off. The two seater tail fins are larger than the single seater's in general so an indication of size on that part only means two seater but which two seater?

That's the most interesting thing ... besides that strange missile (maybe a Kh-59 ???) :confused:

Thanks for that ... never noticed that the MKK also had these darker squares; I thought it's a typical feature onyl found on China-produced J-11.

Regarding the height of both two-seater I'm not sure - have to check some drawings - ... I agree that the UB's tail is also higher than a SK's tail, but as the MKK is actually a hybrid-type with many features from the Su-27M it has - in contrast to the Indian MKI - the taller + squared M's tail.

The squared tail of the MKK seems to give the impression that its taller than the tail of the UBK or the MKI, but in reality, looking at the side drawings, they're the same height as the clipped fins of the other two seaters. The MKI also has the corner patches, but they seem to have a lighter color than that of the J-11s. I suspect these patches are a kind of aerial signal receiver.
