    Vikramaditya is also faster have twice the range, probably more powerfull sensors and better air to ground capabilities (How much weight can F-35B, let alone Harrier pull up in VTOL mode ?!).

    A F-35B will certainly have better A2G capabilities than a Mig-29K launched via stobar. More powerful sensor? The most important part are the airwing, not the sensors of the carrier.

    Clearly a ambitious program no doubt! (and expensive) Yet, will it be stealthy enough to avoid enemy SSK’s (AIP) and SSN’s???:confused:

    if you think it will be as quiet as Ohio class, then yes.

    interesting, Russians will only push you around if they think they can get away with it and get more money from it. They asked for more money in MKI deal too, because they know India badly needs it. All the leverage is on Russian side. If we compare this to the Chinese side, they are asking for more money in IL-76 case, because they know badly needs it and has no other feasible option in the short term. But when it comes to other deals like AL-31FN deal, they are gladly taking a loss in the contract, because they know if they don’t carry forward with the FN deal, China will simply use WS-10A. India should just do what China does with Russia. Refuse negotiation on new deals until Russians learn to honour existing ones.

    The USN is not superior to the Russian Navy.
    If the USN was suddenly the Russian navy then Russia would either have to slash the Navies budget… to obvious effect, or Russia would be in more economic pain than during the 90s.
    The current USN would be an enormous step backwards for Russia, so how could it be considered better for Russia?
    Russia does not invade countries on a global scale so the USNs performance in that is irrelevant.
    The Russians would have enormous trouble just finding a base for all of the USNs assets let alone be able to fund its normal operation.
    And it is not just Russia any other country on the planet would be crippled economically by bearing the burden of the USN and the military benefit would be minor for most countries and would evapourate within a year because of the effect on the country burdened with paying for its existence.

    The fact that the Russians can’t fight three wars and still threaten other countries all at once is a good and normal thing… the fact is that only the US can do this and the US can only do this because it is currently in a position to do this and its government has the will to ignore its own principles and inflict pain and suffering on others to impose its will globally… hense the recurring backlash of “anti americanism”.

    The USSR was interested in peace… something the US may never understand as it has never really tasted war on its soil. Except the war on drugs… :rolleyes:

    If US carrier groups ever become a serious threat in the future launching a dozen satellites would probably take less than a week. Humint will give them at least that length of warning. As its financial situation improves they will be launched anyway, so the capability is coming… and there is curently no hurry.

    The Russian navy is not only inferior to USN, but several other better trained and/or better equipped naval forces. Have you seen what the once vaunted submarine force has turned into?

    Before we get on to the old chestnut that China gets treated worse than India in terms of arms transfers it should be pointed out that there is not actually any evidence for this.

    My personal favorite is the comparison between the Su-30MKI and the Su-30MK2. Sure the MKI is a better aircraft but the reason behind that is not Russia’s attitude to China but about Chinas 1996 desire for immediate capability. The spending splurge that occurred in the immediate aftermath of the 1996 straights crisis does not fit with the long term Chinese procurement and development plans and was intended to try and offset some of the humiliation caused by the arrival of the USN.

    China has got plenty out of Russia.

    China got the crown jewels just as India did

    good points. China buys only mature platforms that are ready from the Russians. If it’s looking for advanced new systems that are not tested, it develops them in house. Actually, by even going for something like Klub, that’s not really mature, they found out the risks involved.

    c’mon tp you are a nice guy, and trust me i mean you no offense or imply any insult when i say this.
    am i the one who is “believeing what i must” or is it you, with this faith based system in a bunch of websites? doesnt it strike you remotely weird that the chinese got a time machine moved to the future, tested a radar which is by no means done and is ramping up testing now, and then came back to present time, with the test results even?! its like some indian website claiming that they evaluated the pak fa secretly, and it didnt hit more than mach 2. well, get the darn thing flying first before claiming a whopper. this aint no different.

    yeah, what I’m saying is that the Russians offered it to China to test out before they finished their own testing.

    coming to china and venezuala- i definitely doubt whether what venez gets will be full spec, but thats a lot to do with us-venez politics. i for one think that nothing state of the art will go to venezuala yet because the us will be monitoring it 24/7 and the last thing, russia needs is for its latest bunch of systems taken down by the usual overwhelming force blitz, but giving its gear a bad name in the process.

    okay, instead of venezuela, we can use another nation. I’m saying that the Russians tend to downgrade their export versions.

    dude, dont know how you can believe in such stuff when everything is against it. there is no evidence that the irbis has been tested by china at all. in fact, its but entering full scale tests now, and has only demonstrated certain facets of raw range in mkk tests and a theoretical possibility that it can track 30 targets, and engage 8 – this from running simulated targets through its present processing eqpt.
    the chinese sources you are depending upon are bunkum.

    and sukhoi wll sell the pak-fa to iran if it could doesnt mean the russian govt will agree to it. time will tell, but i have my money on china not getting the full specs irbis and wisely deciding to continue with its homegrown radars.

    believe what you must. All the Chinese sources that I use have proven themselves in other areas before. I don’t believe export Irbis would be full spec either, but the one China gets will not be any less the one that Venezuela gets for example.

    second, there is no evidence that the f-22 is just 0.1 or 0.01 sq mtr either. the actual rcs is classified and will remain so for another decade and a half in all probability.

    and lastly, they did reach their ambitious goals with the n001…in russian service. including adding long range search modes which werent exported to china.

    I’m talking about N-001 the original, not N-001V.

    Also, from recent open source reports, the chinese were in full force @ maks 07 and were seen devoutly studying the su-35. They seemed to pay particular attention to sub systems such as the Irbis and the engines. Obviously, they are still jumping @ something and the Irbis seems to be it. Thing is the russkies seem to want china to buy the entire a/c and not just one of its subsystems. And even then, one doubts they are going to sell china something that could very well undermine their own security.

    there is no question that 117S and Irbis are good subsystems, but if the engine and Irbis was as amazing as advertised, China would not hesitate purchasing su-35.

    Yes, Irbis can detect 0,01sqm targets form 90 km. Approaching targets. In low frame-speed scan mode, in high altitudes .

    that’s what they advertise, not necessarily going to reach that. Did you see what they were going for before with N-001 and didn’t reach their ambitious goals?

    Let’s put it this way, China has already tested this thing according to JDW and Chinese sources and the Russians are trying to sell su-35 along with Irbis to China right now (confirmed by Kanwa). If this thing can actually track F-22 from 90 km out and other radars available do not have this capability, they’d be jumping at the opportunity. I certainly wouldn’t trust Russian sales pitch.

    @sferrin, Su-35 can shoot AWACS down without radiating a single beam.

    L-175M will pick up AWACS’ signal and that data is all it’s needed for R-172’s launch authorization. R-172 features it’s own multimode seekerhead, and one of those modes is PR mode. While R-172’s small antenna won’t pick up the radiation from 300 km away, it will eventually. Until then, it’s going on inertia, thus no datalink, completely passive.

    Midcourse updates and command correction are not really needed. AWACS ain’t going anywhere.

    Upon positive lock with the PR seekerhead, AWACS is…basically dead. If those F-22’s are in front of it, let’s say 150 km, they are still 100 km short from engaging the Su-35 with AMRAAM. If they visually detected the incoming Novator (it’s a pretty bulky missile!) AWACS may try shutting down the radar system.

    But again, it won’t do much. Upon signal loss, R-172 will just switch to AR guidance, and point to the last known location. The xxx sqm AWACS won’t be a hard target to lock from 100 km with AR.

    In any case, letting Su-35 come at 300 km from the AWACS is a suicide.

    You all seem to forget the AIM-120C-7 range. F-22 will be long detected by Irbis, before he gets L.A. with the AMRAAM. That is going to change with the -120D, but we’re not there yet (nor we are with the Su-35, but it will be a gap, VVS will get first types before USAF gets -120D).

    Regarding plasma stealth, it’s not the cloud all over the plane, for god sakes. It’s layering the radome, from inside. It’s only purpose is to cover the radar antenna, and since the radome is radiotransparent, there’s no need to put the plasma layer outside to have direct contact with air. 🙂

    are you serious? You still believe Irbis can detect 0.01 sqm targets from 90 km out? I guess that’s why China is jumping at this amazing F-22 conqueror.

    What about the Drag factor of raised canopy? Missiles are not that dragy as the raised profile for the whole aircraft and canards. C-130 is underpowered transport and has no relevance to this discussion. I am not even going into weight issues.

    It doesn’t matter how over or underpowered something is. Anytime you add a significant additional weight, you are going to have a significant decrease in combat range. The fact that you think adding 3250 kg will not significantly decrease the range of a flanker shows how clueless you are.

    u are just assuming weight. MKI has canards, TVC engine and Radar that is almost 400 KG heavier in the nose. how can it be the same as Su-30MK?
    http://www.knaapo.ru/eng/products/military/su27SKM.wbp
    there is 5 tons Maximum takeoff difference.

    max takeoff increase means stronger airframe. It doesn’t mean the empty weight is increased by the same amount. Why is it so hard for you to comprehend?

    this J-10 story has no credibility. Since J-10 has been publicly declared give the link to manufacture website that has some data.

    that was an official article, lol. You have no credibiilty.

    Seems like I have to explain it to you in a clearer manner, you slowmo. In this thread, I only claimed that the system was feasible. I did not claim it was actually under research, or that it was already operational. I have stated clearly many times that I did not know, with regards to the latter two. And so all I needed to do to prove it was feasible was to show that the major components needed for such a system already exists.

    In the 054A thread, you tried to prove that a system existed on the 054A by stating that such a system was feasible with China’s capabilites. In actuality, you didn’t even prove that much. But the worst flaw in your logic is equating the feasibility of something to it actually being deployed. That is something you are trying to accuse me of, and it is something I never did in this thread. All you critters are the same, reduced to accusing others of making claims they never did and attacking them based on that. :rolleyes:

    I’m wondering how do people like yourself don’t get any kind of suspension for using names like slowmo and critters for others? But then again, the foul language used in this thread is getting embarrassing, the moderators really should shut this one down.

    It’s kind of interesting that you still say I didn’t prove that much, when everyone seemed to join my side in the debate and you ended up quiting that thread. So, it was only you not believing in the evidence. Whereas in this case, it’s worthless debate between you and Crobato. Nobody cares except you two, really.

    Hey, if you only think something is feasible, why do you still argue like this
    “Its still up to you to prove it, rather than suggest via innuendo that it can.”
    I already said that all the parts needed for such a system are available. What more do you need?

    If you are not trying to argue for the existence of a program getting to this system, don’t use that kind of argument. Just say it’s a possibility and move on. Who spends pages arguing about possibilities? Maybe you just have too much free time. Anyone would believe that you are insisting that because parts are there, the system is also there.

    Don’t try to twist the situation around. It certainly wasn’t like that. You were the one who insisted then that something existed despite you having no proof that it did. My stand then was always that we didn’t know if it existed, and so we could not make claims that it did and base performance on that basis.

    In this thread, I have stated CLEARLY many times that I don’t know if such a system exists, simply because I have no access to what programs are being funded. Crobato first thought that there was no black badget and that he knew everything about the US military. When I pointed out that there was a black budget he tried misdirection and gave a lame ‘so what?’. :diablo:

    Next he tried to question the feasibility of the system, and tried subtly to make it sound as if I had claimed that such a system existed. That was a claim I never made. All I ever claimed was that such a system was feasible. That’s because the major components needed for such a system to be feasible already does exist. Crobato however insists that an idea can only be proved to be feasible if it exists. If it doesn’t exist, it isn’t feasible. Anybody with half a brain can see what’s wrong with that line of logic. Can you?

    I don’t care what you are arguing with him about.

    this is your exchange with Crobato:
    “Its still up to you to prove it, rather than suggest via innuendo that it can.”
    I already said that all the parts needed for such a system are available. What more do you need?

    But it’s interesting the case was that I provided plenty of evidences that I thought were proof, but you didn’t. And then you asked me to “prove it”. Lol, you can deny my evidences as much as you want. point is that I thought they were evidences, many other people on the thread also argued for me (and nobody else argued against me). Forward to this one, you are providing “parts that are available” and Crobato is asking you to prove it. Look familiar?

    Less fuel means less range. Su-30 fuel is not decreased by external load. and external payload has more effect on Single engine light fighters compared to twin engine fighters which has surplus thrust once it reaches certain height. ur comparsion is clearly wrong.

    Combat radius of 1500KM with 4 AAM (alteast 750KG with heaveir R-27) does notpreclude combat radius of 1500KG with 4000KG external load. i have already put Su-27 vs Su-30 example.

    you increased 3250 kg and that doesn’t dramatically decrease the combat radius? Are you kidding me? There is a difference between increasing weight as part of the air frame and then increasing weight as part of external attachment. You obviously get additional drag factor when you hang missiles on the outside. And have you ever seen how much the range of a C-130 class transport decrease with even 1000 kg difference in weight?

    as for your weight comparison, ubk is 17.5 t empty and mki/mkk are 18.4 t empty. Big difference, huh?

    If u want reduce weight in meaningful way. This is the only way. Boeing/Airbus/Sukhoi/Tupolev are doing the same. Because of these composities that Italian and Japanese got so big share of 787.

    huh? J-10 came out to be lighter than the requirements despite using less than 10% composites at the time. If you can reduce weight with better design rather than using composites, then you do it.

    Decrease of 300 to 500 KM in combat radiues for 1200 KG extra weight? this thing is laughable. Su-30MKI is heaver than baseline Su-27SK by alteast 4000 KG not mentioning higher frontal X-section of twin seater vs Single seater but range reduction is only 530KM (Not combat radius). 1200KG extra weight does not mean big thing for an aircraft which has superior aerodynamics than other 4.5 generation aircraft. Just compare Su-27SK,SKM and MK2. There is huge difference in Maximum take off weight. Even if u load SK with 4 tons of external weight and MK2 with 8 tons the difference should be only 4 tons but difference is 8 tons in maximum take off weight.
    http://www.knaapo.ru/eng/products/military/index.wbp
    http://www.knaapo.ru/eng/products/military/Su30MK2.wbp

    1200 kg -> payload, not additional plane weight. If you check some of the figures for some of the well known fighters like F-16

    # 740 nm (1,370 km) w/
    2 2,000-lb bombs + 2 AIM-9 + 1,040 US gal external tanks
    # 340 nm (630 km) w/
    4 2,000-lb bombs + 2 AIM-9 + 340 US gal external tanks

    That’s basically a 740 km decrease from having 2000 kg more payload and 700 less gal of gas.

    And you just have no response to the part about your own source saying 2 R-27 + R-73 for a combat radius of 1500 km?

    withou using composites? tell this to Civillian airlines like Airbus/Boeing/Tuplev/Sukhoi. they are going to 50% figure.
    For light aerodynacmically defcient fighters one to two tonnes in extra weight has huge impact.

    composites is just one way to decrease the weight, this is so stupid I have to argue with you on this. If you can reduce weight without using composites, you will. Having composite does not necessarily make a fighter lighter. It’s one of the methods to decrease weight.

    He didnot mentioned 3000KM flight range. he mentioned 4000/5200KG for 1500KM flight range. which is perfectly reasonable. which no other Fighter can match on internal fuel.

    Except that LCA has much greater wing area with lighter weight. So that lighter weight should transform into greater range.

    you own source mentionned
    Maximum flight range (with rockets 2xR-27R1, 2xR-73E launched at half distance):
    – at sea level, km 1,270
    – at height, km 3,000
    – with one refuelling (at 1.500 kg fuel remaining), km 5,200
    – with two refuellings in flight, km 8,000
    Does 2 R-27 + 2 R-73 sound like 4000 kg of payload? And that’s assuming maximum internal fuel. I still don’t see where you got 4000/5200 kg range from. That’s a huge difference. 1200 kg extra weight could mean a decrease of 300 to 500 km in combat radius.

    As for weight, you can achieve lighter weight with more ways than just using composites. But that wasn’t even my original point, A2A mode means normally carrying 2 MRAAM, 2 SRAAM + 3 fuel tanks. Just to give you an idea, the following is what they list in the fighter escort configuration for SH: wo Sidewinders and two AMRAAMs and the range is 410 NM.
