    why they think EU cannot operationalize fighter AESA. u can just put AESA into Su-30 no need for medium aircraft .

    Russia leader in Indian fighter tender – source

    MOSCOW. June 19 (Interfax-AVN) – Moscow is likely to win the Indian tender on procuring 126 fighters, as it offers the MiG-35 fighter, fitted with an active phased array radar, a source in the Russian defense industry told Interfax-AVN.

    “The Indian aircraft industry has adapted a great number of Russian technologies, and boasts vast experience in aircraft licensed production and maintenance,” he emphasized.

    “At the same time, Indian estimations show that launching the Su-30MKI into mass production will cost India dearly,” he noted.

    “Indian experts say that license producing the Su-30MKI is significantly more expensive that simply buying such aircraft from Russia,” he said. Indian now issues tenders only on licensed production of all combat aircraft components. Russia is the only participant in the tender willing to sell the license for the entire aircraft, including the phased array radar, developed by the Fazotron-NIIR Corporation.

    “There are few phased array radars abroad, as their designers encounter many problems,” he said. Almost the whole of Europe operates U.S. integrated block system, and the U.S. just would not transfer its technologies even to its NATO partners.

    Russian aircraft experts are to visit India in July in light of the tender on procuring 126 fighters. “Among other things they will demonstrate the MiG-35 to the Indian side,” he said.

    The Indian tender also sees participation of the U.S., France, the UK, Sweden, and Israel

    Squirm and squirm. Tell me where the factory says you can compute empty weight by its MTOW.

    By your definition, the Su-30MK2 would be a lot lighter than an Su-27S, right?

    How is Su-30MK2 lighter than Su-27S when Su-27S has 20% more range, 25% more top speed, 10% more altitude and 320 kg less fuel?. u have to look at all parameters.

    Unfortunately for you, aircraft maintenance has a lot to do with complexity. Why do you think variable winged aircraft suffer on this, eh? Between designs with similar engines, yes, the twin engined design is more complex. Are you going to say the Starfighter is more complex than the Phantom? The Gripen is more complex than the Hornet? The F-16 is to the F-15? What are you trying to point with examples that has a much varied engine design like a WWII bomber to a Blackjack or an F-5E to an F-16. Compare planes with more similar technologies and engine designs.

    Starfighter came much before than phanotom. similar is F-15. and F-16 is more expensive to buy than F-15 for the same year. Price shows the complexity. 1998 model F-16E is more expensive than 2006 model F-15SG despite higher number of ordered. F-18E is cheaper than F-16C block 52 even on export prices bases.

    Lets add to that, the J-6 is heavier than the MiG-21. In fact, the early J-6 is as heavy as the late model MiG-21bis. And like I said, the complexity is one of the reasons why the MiG-19 is phased out early.

    J-6 is heavier because it is older than MIG-21. it has nothing to do with design complexity. how close are the weights of MIG-23 and MIG-29.

    Planes that were already made circa before 1988?

    It is again ur speculation. they trialed in 1987. so how can plane before 1988? and why wait five years for such simple delivery.

    The problem is for, Grifo integration also takes up a lot of testing. That means flying and shooting weapons. Developmental and training work is even more extensive and tougher than operational use.

    It also means alot of overhaul and down time. and it hapened in mid 90s. just look at crashes of F-7 on. http://www.warbirds.in untill 2003. figures after that are alot worse

    You really have low standards. When it affects 1/3rd of your aircraft total, that is a huge amount.

    It is temprory. and what happens in other airforces when a plane crashes or they just dont reveal it.

    As a military attache, he probably has his own direct contacts with the Russians and Russian aircraft. Where is the proof of yours that the F-7M has 1500 hr life?

    he posted 1500 hr life. just look at his post. I dont think so he can assume about MIG-29 and Su-27 service lives.

    You are really into denial. Look at all those high tech components and don’t tell me its just “parts”. These require significant advisement in their integration. Facts is, Tsagi is not involved despite your windbag claims.

    why u constantly embrass urself with baseless speculation.

    “TsAGI’s services are used not only by European aircraft manufacturers, but also by the U.S. company Boeing (which tested its Boeing-767 here), Indian HAL, which tested a model of its LCA light fighter jet, Brazilian Embraer-170 and Embraer-190. Currently the Institute is testing a Chinese aircraft whose name and details are kept secret. The tunnel has been used on four models of the T-50 fifth-generation Russian jet fighter, or PAK FA, which means the advanced system for front-line aviation, and other projects not reported in the press. “All this is evidence,” Kargopoltsev said, “that the crisis in the Russian aircraft industry, so hyped up recently, is an exaggeration. Otherwise our services would not be in such a demand.”

    Meanwhile, ARJ21 wing designer Antonov has completed wind-tunnel tests on several scaled-down models at its facility in Kiev and those of Russia’s TsAGI, the Central Flight Test and Research Institute in the Zhukovsky region of Moscow. On the eve of Airshow China 2004, Antonov declared that it finished the first part of the wind-tunnel testing and has frozen the ARJ21’s wing configuration. The Ukrainians have also issued recommendations on empennage structure improvements and received an additional wind-tunnel test contract

    To speed a decision on the final wing configuration, ACAC has commissioned four separate wind-tunnel testing regimes, said Tao, under way simultaneously at Antonov, TsAGI in Russia and at state facilities in Holland and China.

    And tell me where Sukhoi has given you a ridiculous formula where you can compute empty weight from MTOW, huh?

    whats so hard about it. MTOW has same standard definition for the same factory.

    No. The F-35 is actually intended to be much more maintenance friendly than the F-15. Certainly the F-16s are cheaper to maintain than the F-15s also.

    It does not change that the J-6 is more complex than the MiG-21. As a matter of fact, the MiG-19s complexity and the problems that arise from that, is one of the reasons for its early demise.

    we are not discussing aircraft maintain but design complexity for building purpose. ur automatically assuming that twin engine are more complex than single engine.

    You really have no idea of the life stages of the J-7, do you? Between 1982 and 1988, this is when the F-7B and F-7M were being exported. The F-7Ps belong to these groups. CAC stopped production of the F-7/J-7 to make way for the J-7C/D, which was not successful. By 1991, the J-7E with the double delta wing is the model that is being produced.

    so what were they supplying between 1990-93? and supplying does not mean operational service as it take couple of years for Grifo integration.

    Where is your 2 or 3 crashes by the way?

    One happened last March.

    http://www.ibnlive.com/news/mig21-crashes-in-wb-pilot-missing/34902-3.html

    They grounded the -bis specifically.

    http://www.rediff.com/news/2002/may/03josy.htm

    You can see the flight hours here.

    u should understand the report before making assumption about it. Aircraft are built between late 70s and early 90s. 1700hrs are put on them on average which is by itself more than 1500hrs for entire F-7 life and it effected six squardons (100 aircraft the at the most) out of 300 BIS procured.
    It has nothing to do with upgraded BISON where engine still remain the same.

    No. Pepe happens to be a Brazilian military attache. He must have been something to be allowed to visit the factory and shown this stuff. And what are you?

    so how he came to conclusion of Russia aircraft service life by looking at Chinese F-7M 1500 hr life? when Indian built aircraft has 2600hr life.

    That’s all you can come up with eh? As far as Chinese are concerned, they don’t trust Russian civil air techs which is the reason why they chose Western partnership.

    No western partnership but Parts. Russians sells on Cash or natural resource based. Western banks provide leasese.
    Russian leases started only in 2006 and that for very small amount. nothing like financing 100s of aircrafts.

    ARJ-21 does not use Tsagi. It shares a lot of Western technology.

    http://www.aerospace-technology.com/projects/arj21/

    The ACAC consortium, formed in 2002, includes the Shanghai Aircraft Research Institute and the Xian Aircraft Design and Research Institute, and several aerospace companies: Chengdu Aircraft Industry Group, which is responsible for the construction of the nose; Shanghai Aircraft Company, which will carry out final assembly; Shenyang Aircraft Corporation, which is manufacturing the empennage (complete tail unit); and Xian Aircraft Company, which is responsible for manufacturing the aircraft wings and fuselage.

    “Final assembly began in March 2007 and the first flight of the aircraft is scheduled for March 2008 with certification by the Civil Aviation Administration of China (CAAC) in 2009. A launch order has been received for 35 aircraft, for Shandong Airlines (ten), Shanghai Airlines (five) and Shenzhen Financial Leasing (20). In November 2006, Shanghai Electric Leasing (SE Leasing) signed a memorandum of understanding for 30 aircraft.”

    The flight deck is fitted with five Rockwell Collins 10in x 8in high-resolution liquid crystal adaptive flight displays. Honeywell is supplying the fly-by-wire flight control system. The avionics suite is based on the Rockwell Collins Pro Line 21 system, including a VHF-4000 voice and data transceiver and an IRU-4000 digital data and audio processor. The system supports current VDL Mode 2 communications and also has the capability to support controlled pilot data link communications.

    A Rockwell Collins FMS 4200 flight management system provides multiple wavepoint vertical navigation, flight time and fuel planning and prediction, Standard Instrument Departures and Standard Terminal Arrival Routes and approaches (SIDs and STARS).

    A Kaiser Electroprecision throttle control module interfaces with the Collins autopilot, autothrottle and the engine’s FADEC. The avionics suite also includes a fully integrated Engine Indication and Crew Alerting System (EICAS).

    “The ARJ21 has a powerful take-off and climbing performance to allow the use of basic airports with short runways.”The navigation systems include a Rockwell Collins solid-state weather radar, a Rockwell Collins AHS-3000 attitude heading reference system, a Traffic alert and Collision Avoidance System (TCAS) and an air data system.

    The integrated cockpit panel assemblies and the cockpit lighting control are supplied by Eaton Corporation. Sagem is providing the flight deck control system which interfaces with the fly-by-wire system, including columns, pedals and central console.

    CABIN
    The 18.426m-long passenger cabin can be configured for 78 to 85 seats. The advanced broad cabin configuration includes wide seats, broad array pitch, a large space between the aisle seat and sidewall, wide aisles, high ceiling and low cabin noise.

    The first-class seats are arranged four seats to a row, with a typical 38in pitch. The tourist-class seats are arranged five seats to a row, with a pitch of 32in.

    CARGO HOLDS
    The front and rear cargo holds have capacities of 12.416m³ and 4.383m³.

    ENGINES
    The aircraft is powered by two General Electric CF34-10A engines which are pod mounted at the rear of the fuselage forward of the swept T-tail. The engines are equipped with full authority digital engine control with a Meggitt Vibrometer SA engine control system and engine vibration monitors and Smiths thrust reversal actuators.

    The relatively thick wing design accommodates large wing tanks of total capacity 12,720l, (10,386kg) of fuel. Parker Aerospace is supplying the fuel system.

    The aircraft has a Kidde Aerospace fully integrated engine and auxiliary power unit fire protection system including cabin fire extinguishers and a bleed air leak detection system. The aircraft is fitted with a Hamilton Sunstrand APS 2300 auxiliary power unit and a back-up ram air turbine generator.

    LANDING GEAR
    “The ARJ21 regional jet is powered by two General Electric CF34-10A engines, which are pod mounted at the rear of the fuselage.”The aircraft is fitted with Liebherr Aerospace twin-wheeled tricycle-type landing gear, Goodrich tyres and brakes and a Parker Hannifin hydraulic system. The take-off and landing field lengths are 1,472m and 1,436m.

    China usually hide the real things to show it is indigenous. like secrecy agreements. there is report in PAK-FA thread about wind tunneling Chinese aircraft from TASGI. this thing is already inferior to An-148 let alone SSJ.

    http://news.finance.com.ua/en/toplist/~/1/3/26563
    The fact the that the Antonov design bureau has helped the Chinese to design the ARJ21 mid-haul aircraft, a would-be competition to An-148, shows that Antonov is certain of its own strength. Balabuyev has said that the Ukrainian aircraft will fly at a higher altitude and will have a number of stronger features. The market is big enough anyway. Balabuyev told the president of the AVIC-1 [Aviation Industry of China No 1] Chinese company which is going to build ARJ21 that there are a lot of places in China where high-altitude planes are needed, so the Chinese will come to buy the Ukrainian aircraft, while the Ukrainians will not need the Chinese model.

    Balabuyev often repeats that planes do not come out of eggs like chickens, but are made in creative pain and effort. One can only hope that the result of such efforts by the Antonov design bureau will be a new wonderful plane – the new Ukrainian Globemaster

    http://www.kmu.gov.ua/control/en/publish/article?art_id=53619262&cat_id=2291893
    Antonov’s Deputy General Designer Oleh Bohdanov told that “all Chinese partners are interested in deepening cooperation.”

    Antonov plans to develop the ARJ-21 airplane with AVIC I. It is implementing two contracts under this project.

    Moreover, the corporation plans to conclude another contract in the future.

    AVIC I is cooperating with Antonov on development of the ARJ-21-700 airplane, a regional jet that will be capable of carrying 60-90 people. Antonov designed the wings and other parts of the plane

    Wrong. You don’t know anything. There is no such thing as you mention. While the MTOW differs, the weight of all three planes are practically the same, save for a few hundred kilograms here and there. Yet the MTOW figures are changing via tons.

    this from Sukhoi. Same aerodyanamics like Su-27 but lighter than F-18. Su-35 is nothing more than Su-27 with lighter avionics. Similar is Su-27SM. which is considerably lighter than Su-30MK2. Speed, range shows the difference.

    According to him, the nozzle will be controlled with the help of the aircraft control system, rather than the engine control system. “It will be an integrated digital system. The new aircraft features the same aerodynamics as the Su-27. There have been quite a number of modifications, since the Su-27 was developed. However, all of them led to increasing the weight and the air drag, and worsening the maneuverability. The Su-35 is fitted with lighter hardware. Given a super-charged engine, its maneuverability will increase dramatically,” Klementyev said.

    He also noted that the Su-35 featured certain state-of-the-art technologies to be employed on the fifth-generation aircraft.

    “The Su-35 is a response to the U.S. F/A-18E/F. They boast similar equipment and combat employment principles, though, the U.S. aircraft is heavier. The U.S. has earlier won the race by fielding better avionics and armament, but I hope it will not be the case with the Su-35,” Klementyev said

    You really are an idiot. Of course, every twin engine fighter is more complex than a single engined plane. Complexity can be quantitatively measured through the number of parts. Having twin engines means double of everything that supports the engine, and not just the engines themselves. There is also the additional engine supporting structure, and you need beefier of everything like the landing gear to support the weight. A J-6 is nearly a ton heavier than a MiG-21F13 empty. And you certainly have no idea that when you have two engines or more, there is a new problem.

    so F-5E is more complex than F-16. Twin engine does not automatically makes a fighter complicated for simple designs. F-35 is far more complex than F-15.

    You are the one who needs to provide data. Like I said, the standard F-7s were all exported in the eighties. China did not export standard F-7s in the nineties because all the J-7s and F-7s then had a double delta wing configuration. [quote]
    they were still providing it untill 1993 and started in late 80s.

    http://www.pakdef.info/pakmilitary/airforce/index.html
    The F-7M was evaluated by PAF in early 1987 and for this purpose two aircraft were ferried to Pakistan and trials were conducted at Peshawar and Masroor Air Bases. The evaluation included both air-to-air and air-to-ground performance. After the evaluation, 20 F-7Ps and four FT-7s were ordered and these were delivered to No. 20 Squadron in November 1988.
    This was followed by delivery of sixty F-7Ps in 1988-89, fifteen FT-7s in 1990-1992 and forty F-7Ps in 1993

    Look at the A-5s still in Pakistani service. How long has that been?

    how many times they are overhauled. just look at the number from previous page in such a short time.

    BS. Only the double delta wing F-7s were 90s batch. Every standard wing J-7 were build in the eighties and China stopped building them at the turn of the decade. As a matter of fact, China stopped building the F-7s to make room before 1988/89 for the J-7C/D which is based on the MiG-21MF. In 1991 they were making J-7Es already.

    so what was they supplyin between 1990-93?

    The IAF fleet currently flies mostly MiG-21Bis, and this is where the crashy ones occur. All the earlier types have long been retired. The -bis has a tempermental engine and a high wing loading.

    and current crashes are not more than any other type for the size of inventory and age.

    Yeah, right. And how many of these PAF crashes are due to aircraft fatigue, huh? Let me point out to you that world wide, the MiG-21F/PF/MF are not exactly the safest aircraft either looking at the Middle East experience.

    And how many IAF MIG-21 which are much older , carries heavier weopons and more flight hrs are due to aircraft fatigue?

    What is funny is that compared to an armchair red neck like you, at least Pepe Rezende, who I believe to be an actual military officer in Brazil, got to visit China and the Chengdu factory, and got to face the data first hand. So it annoys you that his real life data experience does not match your Russian nationalism gibberish.

    so what knowledge he brought which is no known? He simply compared apples and oranges by saying Chinese were building longer life aircraft in 80s which is simply not true.

    Lol. China build a regional jetliner called the Y-10, and it indeed flew several flights but they could not make money out of it. Thus for a while it flew for officials only.

    The main help for AJR-21 is not Russian or Ukrainian, but Western.

    Facts remains the J-11B has its own planar radar and uses its own missiles. It now has its own engine, and its EW/RWR/MAWS are entirely local to boot. That is not speculation. That is fact.

    Western are just suppliers. The key thing in any airliner is Super Critical wing design and Wind tunneling. the kind of result that TASGI gives no one else can do it. Embrarer/Boeing also use it.

    The Chinese intentions of completely building indigenous systems go back to their own recent history where China is either embargoed, isolated (by the West) and when allies do not prove to be trustworthy (the Soviet Union).

    Hence it is strategic for them that they must build these weapons themselves.

    Going completely indigenous has no tactical value. Some of the Russian components may be better than the Chinese, and in paper, something like the Su-35 still seems superior. Going to the WS-10A actually adds logistical strain because it means a new engine to support, when the PLAAF only had to support two lines for their fighters (AL-31F for the J-11s and J-10s, and WP-13 for their J-8IIs and J-7s).

    But the Chinese do it for geo-strategic reasons, and in the long run, they don’t think the Russians can be trusted, especially now with the Russians going right wing and want to resurrect the glories of the old Soviet Union.
    ,

    I think ur living in a past when things were easy to to copy.
    Just look at for how many years Chinese President flying in 747 without Indigenizing it. So during war if GE/RR embargoed engines servicing to Chinese civillian industry. Situation will be worse than Iran. When Chinese whole economic/Scientific/trade is based on outside world it is simply illogical to assume China can indigenize everything. It tried to make unsuccessfull copies in auto industry. u simply cannot hide anything. There is agreement with Russian government of secrecy.
    Ur simply incapable of making a regional airline. without Russian/Ukranian help. and that is even taking 9 years to finish. Too slow progress. Russian finished the first one and building a second RRJ with international certification of western export order already much ahead of China with much less government support.

    http://www.kommersant.com/p-10937/An-148_sold_Russia/
    An-148 is a regional jet designed to carry passengers (80 seats in basic layout) up to 3,600 kilometers; the cruise speed is 820 km/hour to 870 km/hour. The plane costs roughly $20 million, which is cheaper than similar aircraft. Sukhoi’s SuperJet-100, for instance, costs $27 million
    New An-148s will be assembled in Russia and the cost of Russia’s components will cover roughly 69 percent of the price. So, of $200-million budget of the contract, Ukraine will get less than $60 million

    BS. Only an idiot thinks he can get empty weight by calculating off external weapons load and MTOW. You failed to notice that a plane can take off with its MTOW with less than maximum internal fuel load.

    There is no doubt that later versions of the MiG-29 is heavier due to needed structural reinforcement.

    I know these things. From the same firm every calculation is based on same criteria. when Knaapo put 38.8tons for Su-30MK2, 34.5 ton for Su-35 and 33 tons for Su-27SKM. it means the same values.
    and prove it later MIG-29s are heavier than the old ones?

    It does not change the fact that a J-6 is more complex than your average MiG-21.

    thats ur assumption that every twin engine fighter is more complex than single engine. Whats next? A four engine World War2 bomber is more complex than twin engine Backfire.

    Mostly the crashes are. -Bis pretty much started in the eighties.

    provide some data. Considering the fleet size and age and flight hrs taking into consideration. i told u already most of the crashes are in 90s. when supply of spares dried up.

    BS. How is the Bison older by “several decades”. What a liar you are. The F-7s go back to the early eighties.

    I am referring to overall IAF fleet. It dates back to 1960s. Bison is statiscally small part of the fleet. Most of PAF F-7s are 90s batch. so even if u compare Bision crashes with F-7. F-7 are more notwithstanding that Bison fleet is older by a decade and used substandard parts.

    Overhaul periods of 15 years or so for any aircraft is pretty good, amazing for a MiG-21 airframe really, which typically lasts far less than this.

    how is that good. considering the number of crashes of F-7s out of fleet of 150 and that is in the 90s. and now compare the crashes of IAF MIG-21s in first 15 years of service from 1962 to 1977.
    u cannot play games with words. U are simply incapable of making MIG-21s of same quality even in 90s what Soviet built in 60s.

    Yeah, sure :p that’s a future (typical russian thing) upgrade marketed as ready to sell :diablo: Right now the OLS of the prototype MiG 35 can do this :
    But don’t let me ruin your day; if you want to believe that Russians are able taday to manufacture optoelectronics comaparable with what US did in 1990 (when f 14D), be my guest :diablo: 😀 :diablo: 😀 :diablo: …

    PS: I think you realize that the figures for the AAS 42 are for head-on (“cold” tagets)…

    Ur clearly wrong on this one. In MIG-35 OLS video represenation they were showing F-22. it means they have stealth target in mind when quoting those figures. Su-30MK IRST can fully exploit BVR missiles and thats more than a two decade old technology. MIG-35 is based on IIR.

    http://www.royfc.com/news/may/1206may05.html
    The fighter has a digital fly-by-wire control system, is equipped with vectored thrust engines and the newest fire control system which includes itself an improved optical location system ((OPTIKO-LOKATSIONNAYA STANTSIYA)), which allows detection of airborne targets at a significant distance while not giving itself away by operation of the radar, and the newest radar, which allows detecting different types of aerial, ground and maritime targets, including those built using “stealth” ((STELS)) technologies

    offcourse they are confident of technology even in down graded export variants.

    That’s a little exageration. Many sites claim 180 km, but for a maritime Tu 22–that a huge IR target. For a fighter-sized target, I recently saw on a Korean site 100 km for the newer version of the AAS 42 mounted on the F 15K. However, that almost 5 times better than the top Russian system put on the miG 35 (OLS):p …

    I think ur not properly reading MIG-35 figures.:p. they are more related to stealth type targets.
    this is more than a decade old system that was exported to Chinese with Su-30MKK.

    The upgrade also includes a new 52Sh forward sector optronics system from TsKB Geophizika (Moscow) and Umz (Ikaterinburg), which allows the use of laser-guided surface attack weapons such as the Kh29L, and extends the airborne target detection range from 15km to 50km (head on) and from 50km to 90km for targets seen from the rear

    Nonsense. Why? Modern avionics tend to be lighter due to electronics miniturization. Modern avionics are not heavy at all, why, have you seen technicians carry boxed components of these by HAND?

    Su-27SM and MiG-29SMT empty weights are not lighter than the original models. They are either the same or heavier. Whatever weight savings are made in one area, it is compensated on another area that is beefed up for greater strengthening for longer airframe life and higher payload.

    how is they not lighter. Just simply calculate from MTOW and External weopon load. they are lighter than original models.

    BS. The J-6 is actually more complicated and heavier than the MiG-21 due to its dual engines. One of the reasons of its phase out in the Soviet Union was its complexity.

    Soviet Union is not China that they have to fly MIG-19 for 40 years.they can produce and maitain much more complex aircraft decades ago.

    Oh really? In India, prior to 2005, the number of MiG-21 crashes seem almost monthly and its almost concerns one type. In the last two years they have greatly cleaned this up. And that’s one country.

    are they all of Bision models? Even Bision is 20 year old airframe.

    And which export J-7 are overhauled? Let me know. Which, when or where, or you just pulled this out of your ass as always.

    If export J-7 are not overhauled so what is these numbers.
    all F-7s are overhualed or Rebuilt in span of 15 years at most. and when u count 30 to 40 crashes. this record is even worse than IAF MIG-21 which are much older by several decades and total number appraches 600 to 700 aircraft. and Most of them are Indian built and according to MIG used substandard parts in 90s that was also the cause of crash.

    Europe skipped the US 1st gen. T/R modules too heavy, too expensive, too unreliable. French bought some US 2nd gen T/R modules as development tools, so they were able to work on the software while waiting for T/R modules they thought good enough to use, which they now have. I think UK used lab samples for the same role.

    Europe is now mass-producing “1st gen” T/R modules a fraction the size & weight & with better performance than US 1st gen, similar to current US T/R modules – and that’s what European “1st gen” AESA fighter radars have. Having already spent time & money on the software, turning the fighter radar prototypes into effective radars can be quite quick. Depends only on funding.

    Other types of European AESA radar are already in service, some in the USA 😀 . USCG is buying Selex AESA radars for its patrol aircraft, for surface search. Opeval earlier this year, & IIRC now in service.

    Russia does have a flying prototype, though its T/R modules are big, heavy & power-hungry compared to European.

    USA is ahead, but far less than you imply.

    Russia flying prototype is for export. It say nothing about domestic production. JSC Sveltana is going to produce GaNs based modules Radar in less than 4 years. they said the combine AESA with meteric wave first in world.

    Why? It has nothing to do with the avionics. The Su-30 has a much more strengthened landing gear to begin with. Even if your airframe has the theoritical strength to handle greater loads, maybe your hardpoints are not individually stressed for this.

    It has cleary to do with avionics. u need airframe strengtheing of several tons to carry extra weight of avionics. why u think Su-27SM and MIG-29SMT empty weights are the same or lighter than the original models.

    J-5s were never built since the sixties, since the J-6s took over. J-6s were built till the eighties but the ones Pakistan had were all built in the sixties. At the low point, pilots in the PLAAF during the Communist era range from 60 to 120 hours. However, since planes are not allocated per pilot and allocated through a communal pool, they are using them well over that number. The trainers see even tougher continous service, since the planes are communally shared and can easily be running well over 200 hours a year. There were J-5s (MiG-17 based dual seat trainers) in one of the pictures of a Chengdu airfield that has a J-10 on it.

    J-5/J-6 are very simple aircraft compared to even MIG-21. u can overhaul it much quicker and since they were made in much greater number. it does not effect operational hours. It is not like all of them are flying at same time.

    Lol and how many -bis has crashed then? BISON includes airframe overhaul and rebuilt.

    hardly two or three in past five or six years. which is much better record than export F-7 which are also overhualed.

    For a guy who likes to mouth about science, you certainly do not know something about it. Ligher avionics would not simply do this.

    To do this, you would need to significantly replace key components to the SK standard. In fact among these components is the landing gear which as to be significantly strengthened (this is one of the main mods of the SK over the S). To reach to the 9000kg, the gear is changed even further, as you can see with the MKK.

    I am only referring to MTOW. why it is so much lower than Su-30? and range and speed is also greater.

    The Chinese probably never had better materials than the Russians who were simply the gurus of titanium metallurgy and who were the ones who passed on these formulas. Pakistan J-6s were received starting in 1965 and guess what decade were they retired and how many decades was that? JJ-5s were long supplemented by JJ-6s but JJ-5s (MiG-17 based) which probably never built past the 70s, are still in service in flight academies even today

    J-5/J-6 are cheap stuff of communist era. U dont know the flight hrs and entry date of each aircraft. unless u know how many were supplied on which date, how many hrs were put and when each batch was retired. u cannot make assumptions. that they stayed for 30 years and there hardly majore improvement. MIG-21BISON is vast improvement over 1980s when they were originally built and they will continue to serve untill 2020. Almost 40 years of service with enhanced capablility like R-77. and IAF have alot more flight hrs.

    Childish behavior. The movement of every important Iranian fighter is known in time of tension. The carrier battle groups are designed to survive a full scale attack of all the former SU could field and Russia may field. ASM with nuclear-heads for example. That is still much more than the USN do exspect from Iran or Syria in a worst case scenario. The USN is in the pleasant situation
    Every adversary has to find, pin-point, track its mobile force and breach several defence layers by that at first. Even the Iran may run out of suicide pilots by doing that. In the end it will change nothing, but to convince the USA to finish every possible threat from Iran. I remember about the Serbs, who did believe that a delay of some time my had prevent a military defeat and the related losses.

    Again making a big mistake in assumption. MIG-31 is stratgic weopon. Any sale means that full backing of Russian intelligence, AWACS and Satellite net work support to find targets in middleast specially Oil infrastructure for Iranian missiles. offcourse Russian will not openly do this because they have to do businee with other Arab countries.
    when Russian were invited into Afghanistan it was not in there assumption that West will back international islamic forces against them. and u can also see the rapid construction of Oil pipelines and shipping ports inside Russia to make it completely independent of EU transportation. For them they have already started ColdWar. And denying Middleastern Oil is the single most important weopon which Soviet Union could not effectively employed because of ideology.

    According to the press bureau of the Presidential Office, Ahmadinejad made the remarks in his meeting with Russian Foreign Minister Sergei Lavrov.
    The two sides’ relations are not superficial but very strategic, he underlined.
