    When did i ever say that budget was the sole determining factor in R&D performance? Sure there are a heap of other factors, but the common difference between Raytheon an NIIP IS budget. THAT was the point i was making. Of course the correlation is not linear, but total budget/funding has a huge effect. What technical institute in the world could continue to perform and deliver in the same manner after having their available economic resources quartered? None. THAT is reality, and that is what the Russians faced in the 90’s. Widespread economic collapse & lack of funding is why you see such a disparity between US and Russian array development. Thinking otherwise is living in a fantasy land.

    So if Budget is the factor so how come they Develop Sukhoi RRJ without Japanese money? or 10 to 1 TWR engine for Flanker for only $71m.
    Today market cap of Gaz/Autovaz/Kamaz is more than GM/Ford/Chrysler combined. Aeroflot is much wealthier airline than all the airlines in US industry. It is the Russian steel magnates that is buying and rehabiiliting US steel mills with European technology.
    Boeing/LM combine market cap is $100B but they got big contracts from US DOD. If it was free market system and Russian NIPP/Sukhoi/Saturn could bid for the same contracts Raytheon/LM/Boeing would be long out of business becasue they can do more with less money and faster.
    ur simply not admitting Russian management of business, economics and Research technology is not only better but more practicall to employ. They dont waste money and time on first/Second generation stuff which is inferior to what they already have with current technology. U will not see first generatio TVC system of MKI in Ruaf but more advance long life TVC system in future combat aircraft.

    I’m pretty sure they were firetesting the FC-1 at least since 2006.

    Can u show me any picture?

    Like the way you attributed Israeli developers with Intel as some product of Russian electronics technology? Jews left Russia because of the antisemitism, and its doubtful they ever worked with scientific establishments there; the technology they learned are from Intel.

    So you think Only Jews contributed to Science which are not even 2% of high end science? you are commenting on things on which you dont have slightest idea what is happening. what is this Visa free travel and Venture capital between Israel and russa is about? or do u think Putin should grant visa free travel to Chinese? u havnet grasp the idea about rise of wealth in Russia

Initially it was a tool for internal use, but now decided to withdraw it on the market as a standalone product – CAD “Ardon”.

    I seriously doubt the 40km range. The Chinese knew that the Russians were cheating on missile specs by firing the missiles at very high altitudes and at very high launch speeds.

    Chinese does not know anything. Just look at Transport and Heli fleet. its pathetic.

    Coordination requires that you have to be airborne at the same time.

    So you want to airborne with AWACS all the time? u only airborne when it is necessary. and since MIG-21 are in large quantities. They can take turn by turn over the area.

    Long range AEW radar costs a lot more than a few million. Even civil radar for airports cost a lot more than a few million.

    So do u think there is no Civilian airtraffic radars in Africa.? those who can fly fast jets sure can afford ground based radar. it is very cheap.

    That information still appears classified. The number of J-7Gs in the PLAAF though might be around 30 to 60 planes but hasn’t gone higher since production has shifted to the J-10. J-7Gs will be built for export purposes only.

    u have no confidence in technology thats why you cannot publish anything. u cannot even show where is that PL-9C and J-7G combo oversea.It happened to Chinese car when it was tested overseas for its claims of safety and but than German engineers has be hired to rectify it.

    Pardon? What does J-7 altitude/staying power has anything to do with your earlier comment, i.e. If you are facing J-7 why would you need Supersonic speed and high altitude for BVR shot? J-7 is not MIG-31 that travels at 70,000 feet.🙂

    Do you know the drastic effect the lower speed and altitude will have on BVRAAM range/NEZ of that R-77? While R-77’s might have a range of 80 km at 15,000 feet when fired form a platform travelling at Mach 1.5 (with increasing reduction in its ability to manuever as the missile travels farther from the platform), i wouldn’t be surprised if it goes down to something like 20 Km if its fired from 5000 feet and Mack 0.7.:) And there you go…almost entering WVR.:) What Crobato meant was that to get the most out of your BVRAAM, you would have to go high up (where air is thinner which will increase your missile’s range) and be fast (kinetic energy increases with increasing speed which will also increase your missile’s range)…and the overall range of your BVRAAM will therefore be much greater than if you fire it from a lower altitude/speed.:)

    BVR missile will always have advantage over WVR missile in speed, range, acceleration, acquisition range of seekers. 5000 feet is still decent height. it is 300 to 1000 feet that is consider low height.
    . that 80KM range for R-77 belong to 1980s production batch. so no one should assume that R-77 exported in 2007 has the same performance.
    this things are classified. But now 2 new R-77 are shown with MIG-35. there was road map published by Vymple in 2006. That put future R-77 models ranges 3 to 4 times the current missile by 2010. so why assume that there is no incremental improvement to current versions?
    Time has moved. R-73 has been exported in thousands but u cannot even show export of even 100 PL-9C on J-7G.

    Moscow’s AGAT Research Institute exhibited its newest design, the AGRS 95-1103M small diameter (150-mm) active-homing seeker. AGAT General Director Josef Akopyan explained that this seeker is specially designed to be placed on a short-range missile in the class of the Vympel R-73 (AA-11), which until now has only been fitted with an infrared (IR) homing seeker head. The company views this is as a necessary development due to the advancements in IR countermeasures that can be used against the R-73 and “because there are air-to-air engagements at close range where this seeker is a more effective option.”

    The comment of the thread so far…definitely made my day.:)

    If you are facing J-7 why would you need Supersonic speed and high altitude for BVR shot? J-7 is not MIG-31 that travels at 70,000 feet.

    can you give any figure for J-7 altitude and its staying power in minutes above Mach 1 with external load out.
    Morevoer what is FOV of its radar so it can search targets by itself. u cannot just deduce from Radar posters and claim that gimbal antenna works inside J-7 nose the same way like proper nose cone.

    Basically the Indians needed some more medium transport helos, and the Mil was obviously the favourite, on price, and because it is already in service, so settled on buying 80 Mi-171Vs. The deal was for 80 Mi-171Vs at a price of ~$650m, but Rosoboroexport have reportedly hiked the price up to over a billion dollars. This was reported in a number of reasonably respectable sources, e.g. Times of India:

    http://timesofindia.indiatimes.com/articleshow/3089956.cms

    The basic story is that some are getting concerned at the fact that prices agreed are becoming subject to significant change – not ideal. This does happen in the West, so don’t think for a minute that I think the Russians are uniquely guilty of this. The problem is that if you keep doing this (i.e. deliberately under-bidding on contracts, only to demand a much higher price once the project is too far along to cancel), you eventually annoy the customer enough to go elsewhere. The problem is that Russia used to have a practically captive market in India (for a multitude of reasons), but now this is changing, and increased competition could cause Russia to lose out. Now is not the time for Russia to be using hard-bargaining – it is a buyer’s market, not a seller’s!

    The question is when $650 price was Originally offered? u cannot sit even for 2 years without signing the contract.
    For Russian products it is Seller Market. First there is tremendous internal demand and than new export markets are ready. third even with increase cost they still provide value for money along with speedier delivery time.

    I don’t see anything there smaller than the nose and radome of an F-5E. Some of the after market radars for the F-5E like the ELTA 2032 and Grifo has been marketed for the J-7.

    Having longer ranged radar does not mean first look first kill. Just remember that.

    In fact, the longer ranged radar can set off the other plane’s RWRs before the other plane can be detected. There are also ways to break off radar tracking, such as “notching”.

    Range of detecting the radar > range of target detected by said radar. And it can go as far as at least twice.

    Finally, in Fishbed vs. Fishbed battle, the issue of IFF is paramount, especially when you have aircraft with very similar radar signatures and IFF equipment in the same battlespace. Even if you detect a target at range its going to be useless if you cannot identify friend or foe fast or far enough—some distance will pass and close before IFF gets the proper ID.

    they have certainly concentrated on improving IFF. can you show me how many J-7G Chinese have equiped with Radar? Grifo does not count it is Italian work. Kopyo order approches 150.

    Indian MiG-21bis fighters to be fitted with new Kopyo-ME radars

    MOSCOW. Nov 13 (Interfax-AVN) – Negotiations on upgrading the Indian Air Force’s MiG-21bis fighters by fitting them with new Russian Kopyo-ME radars, developed by the Fazotron-NIIR Corporation, are underway.

    “The Indian side has agreed to upgrade some of the MiG-21bis fighters, earlier equipped with Kopyo-21I radars,” a source in the Russian defense industry told Interfax-AVN on Monday.

    He pointed out that modernization of 124 MiG-21bis fighters in service with the Indian Air Force, which envisions mounting Kopyo-21I radars, was being completed.

    “The Indian side is likely to decide to upgrade about 20-30 MiG-21bis fighters by replacing their Kopyo-21I radars with Kopyo-MEs,” he said.

    According to him, it would be inexpedient to upgrade the remaining MiG-21bis fighters, since their service lives are almost exhausted.

    “The new Kopyo-ME radar has a resolution of three meters, while the Kopyo-21I has a resolution of 20 m. The Kopyo-ME is equipped with high-speed signal and data processors, which have considerably boosted its performance. For instance, the radar has a target acquisition range of 75-80 km, the IFF capability, and a better mapping performance with a resolution of three by three meters,” he said.

    No but it short cuts the integration. The PL-12/SD-10 integration on the J-10, J-8F, J-11B and JF-17 occur successively over in short years.

    you are mistaken. Can you show me a single test firing from FC-1? and the others are pretty old project.

    The Russians didn’t pioneer missile propellent certainly.

    So do you think this Person is Chinese? In USSR and Russia those names are not revealed . They called them Core group. not indvidiuals. Only in West you can see those names.

    What double or triple? There has never been factory stated figures about any increase in range or kinetic performance since the figures for the R-73E.

    so do u think 30KM is less than your 22 KM when the missile is 15kg lighter? and i ask about burn time. that will show who has better speed and sustain range.
    when Su-25SM was inducted into Ruaf they put range excess of 40KM and R-73 has alot customers they dont need to be that specific. why should Vietnam get the same missile as China?

    Bad strategy, since the MKI would have to be limited in range and speed for the MiG-21s to keep up.

    MIG-21 has external fuel tank and can come and go for many spread out airbases. or ur assuming that they all has to airborne at same time?

    You cannot be assured that the radar sets would be destroyed or disabled by other means, or simply fail to work due to bad maintenance.

    You can never make plans based on best conditions.

    In that case J-7 will lose its way anyway.

    Sorry but real world conditions are contrary. Consider for example, third world environments like Africa.

    I considered all enviornments. Even in Africa they have airports for Civillian control and those who can afford BVR MIG-21 can certainly afford few million dollar of Ground Radar. Africa is very rich now. Just ask Mr South Africa in Russia.

    The KLJ-6E is a gimballing planar radar set. On a fixed position, any planar can achieve at least 45 degrees, if you gimball, as much as 60 degrees.

    Can you show me KLG-6E range in real J-7 tests in news report?

    That information is not clear. However, the radar is a sibling version to those already integrated with the PL-12, like the KLJ-3, KLJ-4, KLJ-7 and KLJ-10.

    kopyo is derived from Zhuk but it does not mean R-77 is automatically integrated into every Kopyo platform. Ew sutie/BVR missile integration into aircraft avionic system is not easy for limited space fighter like J-7.

    Electronics don’t necessarily become lighter in time because most of the weight are in transformers anyway and that doesn’t change. Performance improvements are more apt in propellant improvements.

    so all the seekers has the same weight and motors thrust does not improve or do u want me to show who are pioneers in missile propellent technolgy.

    I have not seen any publicly released information about any performance improvement on the R-73E.

    when TMC can double and triple the ranges of just about every missile than why not R-73 which is the most produced new genertaion missile in the world.

    Very much so actually. However, BVRAAM out does it even for WVR missiles. In some cases, the greater acceleration of BVRAAM actually gives the missile an edge over SRAAM even in close range situations.

    so why state the obious

    Its a waste of time, since if you have an MKI class fighter, the MKI class fighter might as well do it (BVR engagement) by itself.

    Twin seat MKI are good for Strike and command& control. MKI supported by 8 to 10 BVR capable MIG-21 can produce alot better result.

    Never, never assume that you will always have AWACS, other fighter or ground radar support. In fact, combat flight training often builds around the worst case scenarios.

    So MIG-21 has thousands of km range that it go outside Radar coverage which sent it the first time to location.

    Once again, you cannot guarantee that external sensors will always be there.

    I can 100% gurantee that external sensors will always be there for J-7 class fighter to find its target. J-7 radar field of view with small nose is at most 10 to 20 degree. Kopyo on Bison is 40 degree. or do u think it can do random search.

    They are still limited by radar look down and missile shoot up limits which still handicaps BVRAAM use.

    latest kopyo can easily go up to 80km. BVR shot at 20 to 30km is far better than 10 KM wvr shot.

    That’s not what you said in your original post.
    You stated that the Soviet Union did not start the cold war and was, essentially, too broke to stand up to the West.

    I’m not sure what border countries you mention since the USSR effectively subjugated all counties on its border…and made them puppet buffer states.
    When they tried to stand up to Soviet domination..or simply wanted some freedoms (Hungary 1956, Czechoslovakia 1968) they were harshly put down.

    By that definition China, Iran, finaland, Western EU was also at USSR border.
    There was plently of empty land on Xinjian that USSR could taken by force in 1940s. but that is not enough reason for Coldwar across the globe. If there was no NATO. I doubt there would have been Warsaw pact and USSR would slowly disengage from europe with time. NATO existence just increase that time period.

    KLJ-6E/F radars are dated from 2004 and above.

    has it been integrated into J-7 along with test firing of BVR missile? it takes couple of years for realization of BVR project.

    So you are assuming that the PL-9C didn’t have modifications in the meantime? Python 8 has a range of 15km; the PL-9C extends that up to 22km.

    Where i said that Python 3 should have same range as PL-9C? In 25 years since Python 3 electronics and materials has been alot lighter so same motor will give slightly more range but it does not mean PL-9C has anything revolutionary.

    You don’t know the burn time of the R-73. PL-9C outweighs R-73, 115kg vs. 85kg. The weight difference is likely on extra propellant. Israeli missiles are also known to use dual burn mode, a fast initial trust, followed by a prolonged burn.

    Burn time i can approximately know from what Vympel revealed as part of R-73 in 2006.
    this webpage of TMC (tactical missile corporation) R-73E is right there with 105K weight.
    http://www.ktrv.ru/production/68/649/651/
    There is warhead weight difference as Python carries 12kg warhead.

    There are no new R-73. There are however, electronic upgrades to the seeker.

    Surely there are no new R-73. They have been exporting and producing the the same R-73 what they produce in 1983.:rolleyes: TMC export reveunes alone are over $1b per year alone.

    Acceleration is more important for BVRAAM than turning Gs as it means achieving peak speed early, which actually gives you higher PK % in closer ranges.

    Acceleration is not important for WVR missiles?

    A BVRAAM made to turn on its maximum G will also sacrifice energy and speed to do that turn, and reduces the PK %. Its more important that the BVRAAM is not made into a position to even turn at all.

    that exactly i meant. so why repeat the same thing.

    Expect low altitude fight. However, to spot a low altitude target, radar must be in look down mode if you are flying higher than the target, and that generally causes a significant—sometimes more than half the range drop. So if you can track at 70km, hypothetically you may be down to 30km or so. At such ranges you are likely to be in WVR anyway.

    Expect low altitude Fight? do u think J-7 and MIG-21 with there tiny radars can find each other by themselves:rolleyes:. Both J-7 and MIG-21 would need to be guided by either AWACS/Ground radar/or MKI class fighter to be at the position where it can use its fire control radar for BVR shot

    If you are flying under the target, your radar is in look up mode, which offers the optimum range (lack of ground clutter). However, the missile has to travel upward, which means less energy for it and less range. So again, you will probably just fight in WVR anyway.

    There is some RCS reduction applied to IAF MIG-21 to make it below 1sqm. I mention there will be only BVR fight in presense of external sensors. MIG-21 neither has the range nor the radar power to find target by itself.

    MiG-21 type fighters also generally have lower RCS compared to other fighters of the same era. Add radar reduction measures, and MiG-21 vs. MiG-21 battles will end up in WVR, since these aircraft lack radar powerful enough to detect their own small radar cross sections at range and further more deal with it alongside low altitude ground clutter.

    Nope. MIG-21 with missiles and external tanks will be seen from very long range by other sensors. they can use the radar at last moment.

    The Indian Air Force (IAF) is now adding stealth modifications to an existing $340m programme to upgrade 125 of its MiG-21bis fighters to MiG-21-93 standard. Sources for Jane’s Defence Weekly have revealed these secret events in a report published in today’s edition of the magazine.

    Extensive tests to demonstrate Russia’s ability to upgrade Indian fighter aircraft with stealth capabilities took place in front of Indian defence ministry officials at the Sokol aircraft plant in Nizhniy Novgorod on 29th May 2000. The demonstration was highly successful and is understood to have resulted in the Russian government and RSK MIG urging the IAF to adopt the stealth modifications across its MiG-21-93 fleet.

    The core of the demonstration saw two MiG-21bis–one upgraded with stealth technology and one without–being tracked by what is believed to be a Mig-31 in a controlled test of radar-absorbent materials (RAM) and coatings developed at the Moscow Institute of Applied and Theoretical Electrodynamics.

    During its flight the radar signature of the upgraded Mig-21bis was shown to be between 10 and 15 times weaker than the regular MiG-21bis

    There are two radars being offered for the J-7G/G2. The first is the KLJ-6E. The second is the KLJ-6F, and F in Chinese parlance represents a character that stands for air defense and interception. Hence why the J-8II with the PL-12 capability is called J-8F.

    The KLJ-6F is the KLJ-6E with the added SD-10 option.

    What year those radars belong to? because Kopyo of 2008 is vastly different than what is fitted to IAF MIG-21 Kopyo-21 from early 90s , which is agian superseded in 2004 by Kopya-M and further refined for Su-25SM pod.
    10 track, 2 engage from 1998. Now there is joint venure of Phazotron with India.

    http://www.airfleet.ru/index.php?staid=1001248
    The Kopyo radar makes it possible to detect and lock on up to 10 targets while scanning the space and executing an air-to-air radar-guided missile attack against 2 targets simultaneously in the long-range air combat

    As an added note, PL-9C has much greater speed than the R-73, under Mach 4 vs. Mach 2.5+. Full range is up to 22km.

    So PL-9C has Mach 4 speed and 22 Km range so what is the burn time of the missile? or do u think missile travels at constant speed with no time for acceleartion and deceleration.
    Mach 2.5 is the effective intercept target speed that R-73 can handle and that is 20 years old figure.
    V-3S is Python 3 with Mach 3.5 speed. And V-3P is R-73. So if south african trails of early 90s put R-73 ahead of every other missile they had or in development so dont u think R-73 alteast has Mach 3.5 Speed if not more? they put range of R-73 and Python 3 the same.

    http://www.saairforce.co.za/the-airforce/weapons/68/v3s-snake-rafael-python-3

    BVRAAMs have superior acceleration over SRAAMs though. SD-10 can accelerate up to 40G, while the PL-9C up to 35G. We can assume similar ballparks for R-77 vs R-73.

    PL-9C is same airframe as Pyhon 3 category. Old R-73 pull 40g. Newer are in 60g category. BVR missiles usually has lower Gs.

    For BVRAAM to be used at full advantage, you have to have the launch platform flying past supersonic speeds and at high altitude. Unfortunately, MiG-21 types will run out of juice fast and just isn’t likely to be able to exploit BVRAAM to their full range and NEZ. For the cost of the missile, PLAAF has decided its better used on the J-8F and above.

    If you are facing J-7 why would you need Supersonic speed and high altitude for BVR shot? J-7 is not MIG-31 that travels at 70,000 feet.

    Typically MiG-21 types also tend to battle at lower altitudes. Here ground clutter tends to reduce radar range. Air density also increases air drag that also reduces the launching speed of the aircraft, the flight range and speed of the missile—while at the same time, the air density also makes the aircraft more maneuverable and easier to evade the missile.

    So what altitude fights you expect from MIG-21 with there tiny fuel capacities and deficient engines exteernal fuel tank and missiles that are not semirecessed. BVR missile gives the ultimate chance for MIG-21 to shot down another MIG-21 as the missile itself has greater energy and seeker has much greater acquisition range so u can safely turn around and leave the missile for its own. If BVR missile in todays age cannot shot down a MIG-21 which can hardly pull more than 7g and have no fuel capacity to enter the fight again that BVR missile pretty much useless.

    Ruaf called it Superior than Su-30MKK/MKI so by defintion it is better than F-15E. Ruaf will not create all new jet when if it has essentially the same role as Su-27SM or Su-35.

    Precisely.
    By this logic, latest models of J-8 with bigger radar, better acceleration and climb rate would toast a J-7 everytime. But I dont think that would be the case. The fact that Bison performed well against F-15s in those exercises with the latter fighter being better in almost every aspect is the clearest of all indications that BVR is not all that simple.

    When it comes to WVR, my personal opinion is that the fighter with better missile/HMS is more likely to win and manueverability/agility is spite of its importance comes second. While a F-22 will win BVR against similarly equipped Mig-21 on more than most occasions, in WVR it could go either way.

    J-7 does not have expensive EW suite nor MAWS or massive internal capacity to use afterburner. A single R-77 shot in no escape zone will be deadly against J-7. New Agat seeker has more than 25 KM acquisition range.
    BVR missiles are much faster than WVR missile. R-77 can intercept at Mach 3.6 while R-73 is limited to Mach 2.5 intercept. and those are figures for decade old missiles.
