That fantasy “site” you are referring too happens to be giving a specific time line, names and data on the projects. And you?
The fact that JH-7 uses a Rolls Royce engine does not make Rolls Royce the designer of the plane. By your logic, the Gripen would be designed by GE.
Oh like some Russians that want to claim that the Yuan class submarine is a copy of Kilo class. The only thing similar of the two is the torpedo tube layout, and everything about the two subs are very different, in dimensions, proportions, plane designs and all. Now they want to claim the Yuan is a copy of their Amur, despite that the Yuan came out two years **ahead** of the Amur and is —much bigger—.
Oh and just like the 093 Shang class = Victor III class argument that got totally sunk the moment the first publicly revealed photos of the Shang were revealed.
China did study the splitter intake technology from the MiG-23 but splitter intake technology itself is NOT Russian. They can easily study that from crashed F-4 Phantoms too, the design is still the same, and the Russians probably got the design itself from the US.
On this case however, you’re the one trying to rewrite history. You have never managed any counterpoint to the historical arguments and data. The logic is so fraught with inconsistencies.
Why does China, who is almost at that point in arms against Russia, get the blueprints of the SU’s latest fighter for FREE, when more trusted Warsaw Pact nations DIDN’T. When India, a closer ally to the Soviets, DIDN’T either.
And why this plane? Why not the Su-7 Fitter or some other design?
Another argument against you is that Ye-152 is a fighter and interceptor that was intended to be used by the PVO or Strategic Air Force, and the Russians simply don’t export away or share their strategic assets (though some Foxbats went to Iraq). And they would certainly not GIVE AWAY THE BLUEPRINTS OF A STRATEGIC WEAPON FOR FREE TO A POTENTIAL ADVERSARY. That would be like giving the blue prints to the Tu-160 for free to China. Look at the fact that Russia DID NOT SELL MiG-31s to China, and they were already at infinitely friendlier terms terms, and China was going to fork out money too.
Here are clearer pictures of the Ye-152. As you will note the Ye-152 has SINGLE ENGINED versions, and in fact the original was designed that way. The J-8I was designed from the start to be twin engined and never was designed to be single engined. That fact alone tells you that there are great internal airframe differences.
http://www.aerospaceweb.org/question/performance/q0248.shtml
Crobato
The MiG-21 documentation was delivered to China, the J-8 is not a exact copy that is true, it has some differences, however what i have read in Russians sources is The J-8I follows very closely the Russian interceptor Ye-152A code name Flipper, it is the result of the MiG-21 manufacture experience China had and in some sources say China recieved the YE-152A technical documentation, the J-8I does not need to be necesarilly the same aircraft, it can be a modified YE-152A, the MiG-21/J-7 as slightly modified in fact it had two guns instead of one in Soviet MiG-21s, the parachute was located also in different compartment.
This indicates that the Ye-152A documentation was not totally the base of the J-8I, also it does not mean they were going to base the J-8I totally in the Ye-152A, when the Russians say it follows the Ye-152A means it was modified.
The J-8I and ye-152A have different radars and different cockpit and canopy arrangement and a different performace parameters changed the aircraft, in fact if the J-8I follows the Ye-152A also it follows the MiG-21 in some aspects.
In my humble opinion the J-8 is a indigenized Ye-152A and up to a level an original design however it does not mean it has not some Russian influence.
And you can prove that they didn’t purchase a MiG-23 specifically for display, right?
yeah Egyptian MiG-23MS yeah for display they should buy a MiG-25 and a few more F-15 and F-16s for display purely for display i guess the USAF will give them an F-117 and the YF-22 for display yeah SOC
The circumstantial evidence DOES NOT EVEN support commonality. And the historical evidence are AGAINST this issue.
Maybe you should study the YE-152 closer, to note that it has a much more substantial spine in the back of the fighter. The difference of what you put into the spine makes a crucial difference in the way stress loads are managed in the entire airframe and in fact, underwrites completely how the airframe would have been designed.
The fatter spine means that fuel is likely to be stored in the spine of the YE-152, but the J-8I only has a thin spine. That makes a MAJOR difference in the internal layout of the two aircraft because of the allocation and deallocation of fuel storage within the aircraft would be totally different. This would also affect the center of gravity of the two aircraft, and that means redesigning the internals to make up for the COG differences.
You can see for example that the Ye-152 is not as tail heavy as the J-8I as the latter required two ventral fins for rear stabilization.Now all these changes are COMPOUNDED by the fact the two have different inlet designs. The YE-152 is more outward and has a larger inlet than the J-8I’s. These changes means changes in the intake tunnel, which in this kind of semi-monoque, means literal changes in the airframe. The inlet differences show they’re not sharing even the same data on the air flow feeding the engine.
The YE-152 is also already forecasting the changes that would show in the 3rd and 4th generation MiG-21s, and yet the Chinese never heard of them and went to a totally different approach.
The YE-152 does have two ventral fins

and has a narrow spine

The difference in inlet cone/ramp/radome is explained because the J-8I is faster than the Ye-152A

http://www.airwar.ru/enc/xplane/e152a.html
The Ye-152 is a more crude design but we can say differences do not mean not having a common origin but simple refinements
Just because the J-8 resembles the one of the Ye-150 series aircraft does not mean they are related. Or are we to assume that the Tu-160 is simply a B-1 derivative, or that the Tu-144 was a Concorde derivative?
Yeah yeah yeah so then becasue the chinese they do have a few MiG-23MS in the hanagar of the aircraft carrier Misk means they did not reverse engineer the MiG-23 ventral fin and inlets on the J-8II yeah yeah more denying
see this page you can see the MiG-23MS in China and the report is from China Today
http://www.chinatoday.com.cn/English/p40.htm
You are absolute correct about 2008. But what has changed really?
The OKB MiG did claim that an avionic-upgrade gives a rise 400% in combat effectiveness. The Leopard is new built and the real question is, is it good enough to fufffill the intended mission right now and in the future? My answer is yes! The engines are just in need to achive that, when all performance gains will come from the avionic and the related weaponary. Neither the Su-24 nor some other strikers did receive new engines, because the gains from that are not worthwile the gains in most cases. When the Leopard was designed in the 80s, that was done with the engines at hand. In that time-scale the AL31F was out of reach for the Chinese.
More intresting is, that the AL31F did not offer some advantages in the critical sfc. So there was no justification for a redesign and switch to the AL-31F to make use of that, when it came available in the 90s. The Chinese are wise enough not to modify the Mk202 design, except the use of newer materials, when available for higher TBO.
By the way, the AL-21Fs are over a decade younger than the Speys and still worse in sfc. (0,9 to 0,66)
The JH-7 can not be compared to the swing wing aircraft F-111, Panavia Tornado and Su-24, in the case of the Americans and Russians before the Su-30 and F-15 they had swing wing aircraft, the VG swing wings aliviate the ride at low altitude and the relatively low thrust of their jet engines.
China made a simplier design, no VG swing wings, no VG inlet ramps and a very retarded jet engine development with low production aircraft in fact the JH-7 is entering service when the Russians are getting the newer Su-34 and Europe is getting Eurofighter for the omnirole mission.
Now China in one way was unable to cheat the British as they did to Russia in the 1960s, Britan did not allow the complete set of elements of the Spey to be delivered to China and the essential parts were to be send to China by Rolls-Royce, in fact Rolls-Royce protected its engine to avoid what happened to the R-11 and other soviet engines.
When the British allowed the Chinese the license the Chinese were already way behind in time scale, the JH-7 is not in reality underpowered but undoutedly it has not the right aerodynamics and what it happens it uses the wrong airframe, it is a very similar design to the Panavia Tornado but with a Sepecat Jaguar configuration in fact they used an airframe that in Europe was used in the 1960s and not the 1970s Panavia Tornado aerodynamics.
This all make the aircraft a very anachronic design, it is not a dogfighter like the Su-30 or F-15E, niether has the smooth ride of the Su-24, F-111, or Tornado, it also has no the stealth of even the Su-34 or the multirole of the Eurofighter.
It is a good aircraft for China in terms of design experience but as a fighter bomber it is a very 1960s design in few words is a very old concept in terms of 2008
The engine chosen was the Rolls-Royce Spey turbofan, successfully used in the West on the Buccaneer, F-4K/M Phantom and A-7 Corsair. In 1975 an agreement was signed with Rolls-Royce for the co-production of the Spey as the WS9. The Spey represented a new generation of engine technology compared to the Russian-derived powerplants then available in China. A trial production batch of the WS9 began in 1976. Production of the engine is reported to have continued, even though slippages in the JH-7 development programme meant that there weren’t any aircraft to take them yet. Rolls-Royce also provided 50 Spey Mk.202 engines as ‘patterns’.
The first JH-7 prototype (coded 081) was rolled out in August 1988 and made it’s first flight on 14 December 1988. This aircraft first went supersonic on 17 November 1989. It is reported that a total of five prototypes were built (coded 081 to 085), and that one aircraft (possibly 082) was lost in a fatal crash during flight testing in 1994, due to engine failure. Numerous problems with the Chinese-built engines seem to have resulted in the original British-built engines being substituted, after the aircraft was grounded several times. By this time, the protracted design phase and technical problems experienced during testing had caused the PLAAF to lose interest in the design, and in 1991 it placed an order for Su-27s instead
http://www.aeroflight.co.uk/types/china/xian/jh-7/jh-7.htm
At the end the JH-7 has a very low payload for the max take off weight in fact less than the diminutive Panavia Tornado and Su-24.
Ha, when challenged, Mig23 reverts to his tried and tested default postion of repeating the question to the sender regardless of its relevence, and he never seems to learn how stupid that childish tactic is no matter how many times he is proven wrong. :rolleyes:
Are you even thinking about what you are talking about? You try and prove a negative. Go on. Prove that there is no other life in the universe. That is the same as what you are asking and its a plain ******** request because it can’t be done. And what makes it worse is you know it. Or should do, since its been explained to you enough times already.
You make a claim and you back it up with evidence. How bloody hard is that to understand?
And when I have done anything of the kind. Quote me. And I dare you to ask me to prove that I didn’t say that. :rolleyes:
Where has there been any such claim made in any discussion on this forum?
Yet more plainly made up BS.
Says the troll who has spamed every Chinese related threads with ever increasinly desperate claims of Russian influence in a transparent and pathetic attempt to leech credit.
And that is relevent how? In all cases where foreign help was given, it has been clearly documented and published, unless the supply wished it not to made so, as was the case with the PL8, but then that has never been Russia’s problem so it doesn’t apply. That makes your baseless claim even less plausable.
And that is not the same thing as the Russians designing the J8 itself. Using a readily available engine is building on existing tech, not asking the engine maker to design your fighter for you.
Even more blind BS. In all cases where the J8 has adapted foreign tech to improve the design (the Mig23’s side intakes, American help in peace pearl etc), it was well documented and published. Which once again strikes a blow at your claim since there is no offical acknowledgement of tech transfer by anyone.
And every single one of those cases have been acknowledged and well disclosed. So what makes your blueprints so special? Nothing. The only one who should be embaressed is you.
It also looks like the Jager is ‘many ways’ as well, and it all means ziltch. Looks are superfical and mean little. Sums up the bulk of your posts pretty accurately as well.
The only one trying to rewrite history is you with this baseless and plainly implausable conspricy theory, that has zero historical evidence backing and flies in the face of well documented and publicised historical accounts.
That is just the latest in a very long line of such attempts by you to leech as much credit as anyone would let you from as many Chinese projects as you can get away with.
В начале 60-х годов при проектировании истребителя J-7 было решено установить на нем лицензионную копию советского двигателя Р-11Ф-300 конструктора Туманского. В Китай были поставлена техническая документация на этот двигатель, однако она имела пробела в описании некоторых частей двигателя. Инженеры Shenyang решили проблемы возникающие при производстве двигателя своими силами и к октябрю 1965 года первый WP7 был готов для проведения испытаний. После испытаний серийное производство было начато на заводах компании Liming Engine Manufacturing Corporation (LMС).
In the early 1960s in the design J-7 fighter aircraft, it was decided to install it a licensed copy of the Soviet engine R-11F-300 from the Tumansky bureaux. China recieved the technical documentation of this engine, but the documentation missed the description of some parts of the engine. Shenyang engineers solved the problems encountered in the production of the engine, and by October 1965, the first WP-7 was ready for testing. After the test series, production was launched at the company’s factories Liming Engine Manufacturing Corporation.
As you can see it is a R-11F-300 even if the Chinese engineers solved the problems was in part to the russian help training their engineers
http://www.airwar.ru/enc/engines/wp7.html
При разработке двигателя инженеры фирмы LMC использовали опыт создания двигателей семейства WP7 и конструктивные элементы советского двигателя Союз Р-13 конструктора Гаврилова.
here it says the WP-13 uses elements of the R-11 and R-13 in order to build the WP-13 by the way the R-13 is a derivative of the R-11
http://www.airwar.ru/enc/engines/wp13.html
хотя отмечалось чрезвычайно низкое качество двигателей WP-7 (такое обозначение получили в Китае советские Р-11Ф-300). Их ресурс составлял менее 100 часов.
however they mention the WP-7 was of extremely low quality due to the lack of some documentation and had a TBO of less than 100 hours
http://www.airwar.ru/enc/fighter/j7.html
В печати описывался случай, имевший место в 1975 г., когда пара советских МиГ-23 сбила J-7, нарушивший границу. Причем утверждалось, что “китаец” упал на советской территории. here it says a chinese MiG-21 AKA J-7 was destroyed by a pair MiG-23s in 1975 near the chinese Soviet border when it violated the Soviet air space and its wreckage fell in Soviet territory
Do you know anything about design at all?
You cannot just make everything 10,20,30% bigger/smaller without needing to make adjustments to the design itself. Fighters jets are so optimised that even changing to a different engine type could easily need massive structual and even areodynamic chances. Those changes are also supremely optimised and follow fixed and highly specific physical laws. Air has the same properties no matter of nationality.
The soviets and Chinese also shared the same theoretical foundation, so in effect, they are trying to solve the same problem with the same equations and many of the same technologies. What you are suggesting is akin to arguing that a class of students all copied off each other because they came up with broadly similar results when ask to solve the same question after being taught by the same teacher and using the same list of equations. Its hardly rocket science to see how similarities in design could easily result without design transfer.
And its laughable that you could have the nerve to accuse others of being blind when you have absolutely zero evidence of any tech transfers and what you are suggesting flies in the face of the well establish timeline. You have presented nothing other then off hand superfical observations that basically only boils down to, ‘well they look similar’, and thats hardly even worth considering other then to dissmiss. Come back with something akin to evidence and then we will talk. Till then all you got are hot air.
Man i do not know why you worry too much if it is a a design with strong MiG influence or not, at the end the j-8I was a very nice looking aircraft and helped China to adquire the needed experience in aircraft design, some russian sources might say it used the data and documentation obtained from the Ye-152A, however the important point is China designed an aircraft very likely independently for the first time, it is a fact they used some MiG training, Russian made machinery and very likely the information they could had gathered from the Ye-152A since this information was of great help.
Those Russian trained Chinese engineers could interpret the Ye-152A very easily since they were very likely used to russian manufacturing philosophies.
At the end the Chinese built two very good looking and practical aircraft, the J-8I and J-8II and these aircraft have been developed to the degree of achieving what they wanted a F-4 type fighter.
Can it fight with fighters and strike aircraft like the Indian MiG-27, Sepecat Jaguar, North Korean MiG-23MLs and Japanese and South Korean F-4S well i guess it can and modern versions will be able to patrol the Chinese air space with some degree of success because not all the fighters and aircraft that might violate Chinese air space are F-22 or F-15s
Flex, are you trying to just argue on each individual post or did you read my other posts?
1. I already said that the Mirage 2000 and Mig-27 were designed for different things. But in the end, the Mirage 2000 provided India its much needed ground attack abilities during Siachen.. something that should be the role of its MiG-27.
And yes I even mentioned the Jaguar, India has been more serious in upgrading the Jaguar’s capabilites than the MiG-27. Many countries that operated the MiG 23 already retired them, even before retiring their older technology MiG-21s. You may ask why they would do such a thing. The truth is.. swing wings are costly machines with even more maintenance needs.2. Its convenient that you ignored countries that retired their MiG-29s. Czech Republic, Romania, Germany to name a few.
3. You mention people buy western because of politics. Well of course politics has a factor.. people buy Russian because of politics as well. Thats how the arms trade works.
4. The issue was never about the purchasing habits of what a country. Its well understood that countries have political and financial reasons as well as capability interests when making arms purchases. They have their reasons and that was not what I’m talking about.. but certain people here are trying to retort to statements I’ve never asked or made. India buys Russian and Western aircraft to diversify its sources and also, to make up bulk which is the case with cheaper Migs. That was never in question. The statement I made was that between these two, India (and a few other countries) prefer their western fighters. no more or no less. We could argue that they don’t or that they really do.. but instead the Flogger-Star49-Flex gang want to argue about things outside of this scope. you must realize that even if say India prefers its mirage 2000, they will still buy Russian for political and other reasons. so will many other countries. but of course you are intent on turning this into a fight between biased pro Russian groups here and biased pro US groups.
5. you also made a statement that most countries buy from two sources.. thats not true at all, there’s plenty of countries whose main aircraft are from one source. Korea, Japan, Turkey.. mostly American. Kazakhstan, Armenia, Syria, mostly Russian. there are few countries that operate two comparable aircraft from Russia and a western block nation.
6. ironic how u ask me to state sources when you provide none of your own.

The MiG-27 has been upgraded
First upgraded MiG-27 successfully test-flown
Friday, April 16 2004 18:04 Hrs (IST)
Nasik: The country’s first state-of-the-art prototype of the indigenously upgraded MiG-27 has been successfully test-flown in the first exercise of its kind, Hindustan Aeronautics Ltd (HAL) Chairman R Mohanty said today (April 16, 2004).
The prototype, built as part of India’s upgradation project, was test-flown successfully on March 25, he told reporters.
One of the 40 prototype scheduled to be produced by HAL was put into the skies, Mohanty said, adding it was commanded by Group Captain Mehta.
So far it has done five sorties and all were successful, he said.
The upgraded version enabling day/night vision has been refitted with state-of-the art electronic devices and avionics and its integration has been increased to improve navigational and attack capabilities, Mohanty
http://news.indiainfo.com/2004/04/16/1604mig.html
here more about the MiG-27 upgrade
Cleared in 1996, the project was to have been completed by 2001. But officials admitted it had been delayed by nearly five years because of technical, financial and bureaucratic “glitches” involving the IAF, the defence ministry, HAL and MiG.
Prototypes of the MiG-27 jets refurbished by HAL at Nashik under the supervision of the Defence Avionics and Research Establishment at Bangalore have already been certified. The first 12 upgraded ground attack fighters will be handed over to the IAF later this year.
The remaining 28 MiG-27s, HAL officials said, would be upgraded at the rate of one a month under the $133 million service life-extension programme signed in mid-2001. Over a year behind schedule, this project is due for completion by end-2008.
The MiG-27s, which are undergoing an extensive avionics retrofitting, will remain in service till 2020 and even beyond.
http://www.india-defence.com/reports-1328
What you do not mention and understand is the NATO alliance is also a club where members need to buy NATO goodies to keep the NATO`s military industrial complex alive so phasing out all the Russian equipment was a must, Poland however got all the surplus MiG-29s and bought F-16s as well.
However many developing nations still have MiG-29s and MiG-23s, the germans will also protect their defence industry and comparing a MiG-29A with a the Eurofighter was a good excuse to claim the MiG-29 was needed to be replaced by the Eurofighter made in Germany, yeah but a MiG-29OVT or the latest Su-35BM can be as capable as the Eurofighter
Also consider the MiG-23 was first flown in 1967 and the last MiG-23 was built in 1985, all the Warsaw pact did retire fighters not because the MiG-23s or Su-22 were not good simply they wanted to satisfy NATO standards and reduce spending in old fighters a few JAS-39 or F-16 were deemed a better solution
This is not a reason to say the MiG-23 was less capable than the MiG-21 or even F-4s, simply politics influenced the decision to retire the MiGs and in the case of India the MiG-29 has been upgraded and its engine the RD-33 is being built under license.
in fact another myth you want to create is besides Germany, Romania and Czech republic only Moldova has retired the MiG-29 and mostly because of Eurofighters and Gripens or because the Romania and Moldova are poverty striken eastern European nations without any real adversary however the MiG-29s of Czech and Germany were transfered to Poland where they are active and operational and the Moldavian MiG-29 are in the US some in Museums and some probably operational in adversary units, in order to avoid Moldova sold them to Iran.
Nevertheless Syria, Algeria and Cuba still fly MiG-23s and recently as 2007 at the LAVEX air show several MiG-23 flew

http://elhangardetj.blogspot.com/2007_02_01_archive.html

apparently you have no idea that there was multiple designs for J-8. The stretched J-7 design was most mature and safe.
When the J-8 was in the works, Sino – Russian relationship was **** poor…
I don’t know how your Russian assistance ever came into being considering Moscow was planning to nuke Beijing. LOL
yeah yeah yeah the J-8 look alike to the Ye-152 was the more mature or why you do not say more clearly they had some Russian documents and data to assure success for the program since other progams were out of the reach of Chinese designers
I have been ignoring this pointless side show in the hope that it would die away like all of Mig23’s wild flights of fantasy, but the mind really boggles at your reasoning.
The people who worked on the J8 studied in the USSR and pretty much all of their research and study material came from the USSR. That means that China has effectively the same technological (theory only) base as well as a very similar design philosophy to that of soviet designers, is it any wonder that when tasked with creating different planes with similar design targets, the two sides came up with a similar design? The matter is further compounded by the fact that both sides were trying to make a twin engined fighter based on the Mig21. There is only so many ways you can mode a single engined plane to take two engines, and far fewer design approaches that are effective and viable. Both teams ended up with a very similar design because that is the most optimal solution to the problem they were given using the technologies available to them.
There have been countless similar examples where planes designed by different teams ended up looking similar because their design teams were trying to achieve similar performance characteristics using similar tech.
What more, if you claim something happened, then the burden of proof is on you. If you cannot prove your arguement beyond reasonable doubt, then you have not proved your case. Its as simple as that. Mig23 has zero hard evidence and they only supporting material he has is the dozen a penny internet fansite that anyone could have made up.
Both you and Mig23 have not only ignored the blindingly obvious but also inverted logic itself to try and make this baseless speculation have any hint of plausability, and have put serious question marks on your competance and credibility in the process, not that Mig23 had any to being with, so no big loss for him.
Yeah and you have proven your point with evidence? have you? you do the same you rely in fantasy fan boy sites where they are embarrased of admiting any russian relation the Chinese aircraft have even denying the WP-7 is the same R-11, they call J-7 instead of MiG-21 or WP-7 instead of R-11 and they give a very long list of supposedly hypothesis to prove that there is no relation between the Chinese programs and their original Russian models, yeah yeah yeah the hard evidence is the same leve in both sides.
And later you even claim to be the expert the lectured one and even say i was trying to avoid this discussion but for the sake of the truth yeah i will give you my distorted point of view yeah yeah.
As i said to Crobato i will say to you, China has indiginized many original Russian or foreign designs and has adapted to some degree foreign technology to some of the chinese lead designs such as the JH-7 or FC-1.
The modern J-8II is a good example, it has gotten rid of the original Russian tech in later variants but still the early models did have russian designed technology built in China, nevertheless they went for different sources trying to create a design in the class of the F-4 and MiG-23, have they succeed? yes they have but it does not mean they have not adapted foreign technology and many here are traumatized by the fact Russia gave the basic technology and still has done it.
They even went to Egypt to buy a few MiG-23MS in order to modify the J-8I, they even have displayed those MiG-23s in a Chinese Museum, they got Israeli air to air missiles, Russian head seekers, Sparrows from Italy and Ukranian advice for designing jet engines, they even tried the americans to upgrade the J-8II and later the Russians once more so you like it or not China has gotten foreign tech and that is not a reason to be enbarrased it is just normal many nations do that in order to get technology transfers. and at the end we have an aircraft the J-8II that looks in many ways like the MiG-23 and Su-15, why simply because up to some level China made an original design from previous russian technology adquired legally or illegally
The Chinese designers have their merits and have their originality however getting rid of foreign input by some seudo Historians is a hideous attempt of rewriting history
I have no need to debunk your story, which lacks serious evidence anyway.
Sorry, but Russia did not pass the documentation nor the machinery. They have no motivation for that. That’s just an internet invention by Russian posters. People like to invent myths for some reason because they like to see that a certain project did not end in ignominy. The fact remains that China and the Soviet Union already had a serious downturn in relations even before that project even got started.
By the same logic, Russia would hand over the blueprints to PAK-FA to China for free.
Prove it beyond a doubt. You’re struggling trying to make a fact out of non-evidence. The alleged stories, as you present have serious holes. They never “sold” blueprints, all blueprints were given because that was the Communist way. Why would they give it to China and not for a closer ally in the Warsaw Pact? When the project was finally done, China and the Soviet Union were having military border clashes. Why don’t the SU give it to India because India is a more trusted ally. The J-8 requirement came out from watching B-52s over Vietnam, how can you go back in time before the Sino-Soviet split and ask for the blueprints?
Man why you do not understand what i say, are those accounts mine? no they are not, those accounts come from the Russian sources.
You are free to believe them or not, the facts are:
A) Russia transfered the documentation and the machinery needed to build the MiG-21 and the R-11 engine, and this accounts claim that the derivative of the MiG-21 technology, the Ye-152A was transfered too
B)the Ye-152 and J-8I are powered by the R-11
C)the Ye-152 and J-8 are very similar in aerodynamics and airframe configuration
Some accounts sustain they are not related however it is not totally true because the J-8I has R-11 or in Chinese denomination Wopen WP-7
talk about people using personal attacks and sly remarks when trying to “prove” their point. very mature
and to Flogger, no I’m not Golden Dragon.
Bringing in the Scorpene versus any Western aircraft is flawed. By the same people who argued that India uses MiG-27s because the Mirage 2000 is expensive, it is the same logic. Western equipment Malaysia uses is generally of better quality but Malaysia, despite its economic success, still has financial constraints and still needs to limit funding elsewhere and like it or not, the F-15 can be very expensive and it was never offered in the first place and that fact remains.
As for Chinese aircraft, the Spey is a western engine so what? there were no Russian equivalents that could fit in the JH-7 and China had to make do with what it got. Now the question is, if there was a Russian equivalent, would it have made the JH-7 better? Other aircraft such as the FC-1 and J-10 are temporarily using Russian engines not because they like it, but because there is no alternative at the moment. America and Europe wont sell its engines, but China is very close to fielding its own and replacing it and there goes Russia’s market for engines.
Even India’s own domestic LCA aircraft opted for a western engine instead of an RD-33.
As far as Poland or any other eastern European air arm goes.. note that most of them got rid of the MiG-29s quite fast. It may be manouverable, but its expensive to maintain and a real gas guzzler. The export models were also lacking. Some one pointed out that they wished they got the Gripen. Well guess what, its a western aircraft powered by western engines and western weapons (take your pick, European or American).
PS, Italy isn’t building the Yak-130.. if you actually bothered to study up on some news, they split off and made the M-346 which is lighter, faster and more fuel efficient already. the L-15 will probably be further developed than the Yak-130 at this pace. but hey, i don’t know why I’m bothering to respond to this.. the statement was air forces that operate both types tend to prefer western aircraft.. all this crap you guys are spewing out about new aircraft types and politics when that wasn’t the question.. but it seems that for some, its the only way to argue against what is the obvious.
The M-346 is only a westernized version of the Yak-130, it has been developed independently for economic reasons but still is an airplane that has the same aerodynamic configuration and origin in fact is a Yak-130, it is not a very different situation as when Northrop developed the F-18L and marketed independently its own version.
By the way China opted for the AL-31 and India does build the R-33 domestically under license, this prove you the R-33 is a good engine even the FC-1 has it.
Moscow and Washington’s competition for New Delhi’s attention extends to the defense sector. India is about to begin indigenous licensed construction of the Russian RD-33 thrust-vectoring engine, a definitive leap for Indian jet engine production (though India already produces the base R-33 engine for its existing MiG-29 fleet). The Moscow-based Chernyshev machine-building plant will supply 20 new 18,000-pound thrust RD-33 engines for trials at a cost of about $25 million. Then, under a $250 million deal with Rosobornexport and St. Petersburg-based Klimov, India’s Hindustan Aeronautics Ltd. (HAL) will manufacture 120 RD-33 series 3 extended life cycle jet engines. For its part, Boeing Co. made an offer Feb. 3 that involves the joint development of the F/A-18E/F Super Hornet, which has not yet been sold abroad.

The Spey was sold simply because it was old and for Britain sold a type of engine that basicly no one wanted to sell, even Russia in fact Russia has enough types engines to re engine the JH-7, however for the Chinese it would be foolish to replace an engine already paid with another foreign engine
Hhhhmm i’d put France ahead of Russia in terms of quality to be honest, the Rafale is far more advanced then any Russian jet. Infact i would go so far to say that Russia is really slipping behind, what with the imaginary PAK_FA plane that for the last god knows how many years has been just a year away from flying, its painfully obvious to all but the most unblinkered eyes that there is no aircraft, just a paper plane.
yeah yeah Russia sliping behind with Su-30MKis and soon to be joined by the Su-35BM, when did France or England have built a Tu-160 equivalent? Russia is building now Tu-160s and Su-30MKIs how are they behind?
Italy even is building Yaks the Ya-130

Europe has more money true but Russia still has great scientists, engineers and designers
For that you need no Tu-160 at all. But a cruise missile can be intercepted, too (it is actually fairly easy). And to launch from 3000km, you need to know your target in advance, and you need to know where it is in 4 hours when the missile strikes.
Reminds of the projects to change a B747 into a cruise missile platform. I guess they had reasons not to do it.
Man come on you can do better than that, a B-747 can not fly as fast as the Tu-160 and run away as fast as the Tu-160 yeah it is true its cruise speed it is not as different to a Boeing 747`s but once it wants to leave the battle zone it will go almost three times faster than the Boeing 747 a big advantage is some fighters are chasing you, besides it has a smaller RCS
Talk about reading comprehension,
it seems most of the replies here are simply those who want to vent out to the world their favorite aircraft than understand logic.– the comment on China and Russian aircraft..
Perhaps no one read when I said “whenever possible”. Those J-6s and J-7s Flogger keeps spouting off were from decades ago and during a time when China had few options. Today the story is different. You can boast as much as you want about the Su-30MKK but in the end China has stopped ordering it. the JH-7 uses engines based on British design, not Russian or perhaps you didn’t bother checking up facts? The latest missiles, helicopters, etc are all being bought from Western sources or based on western designs. Only certain things where the West cannot sell, and in which China cannot develop on their own, are then Russian. Of course if you deny these two important facts then yes by default China prefers Russian equipment (sarcasm).-next on Malaysia.
There’s no more follow up orders for the F-18s because they’re not produced anymore or perhaps you guys did not know that? well its not and they can’t order any more however they will order the F-18E.. if you also didn’t know, the F-18E is a different aircraft than the F-18A-D. Why the Su-30MKM then? simple, because the F-15, Rafale, or Typhoon was not offered. and in the end, they wanted an MKM with Western avionics and components, things such as the Radar they could not import so they had to settle for a Russian one, that simple.and all this talk about prices and getting what you pay for..
well you guys pretty confirmed my statements. I never asked the question of quantity vs quality. By stating that the more expensive Western aircraft like the Mirage, is better, while the cheaper MiG-27 is not as good.. is an admission that it is better. The F-22 is more expensive than the F-16, but no one denies its more expensive. People who are unable to accept the fact that on an aircraft to aircraft basis, that western aircraft have been more appreciated by air forces using Eastern aircraft as well, will then distort the question to “oh, but you get more of the Migs instead”.. which was never the question.
come on the J-11, the J-10 has same engines and russian finger prints and are the current mainstay of the Chinese air force, the Russian contribution in the JH-7 is also part of the knowledge they got from Russian tech transfers in engine and radar technology, of course i know it has Speys but the aircraft is has the results of many years of tech transfers and Russia still is there.
You can live in the fantasy world as you always do, but goldie relax Russian aircraft and Russian tech allows Russia to remain as the second most advanced nation in military aircraft technology.
