    there is no guarantee that Stealth wont be detected. Su-35 offers superior performance, range and integrated avionic system across the board. Just BVR shoot capability with high altitude perfomance, fbw control 3D TVC will give it edge in any combat.

    you continue to be a better salesman than the Russians themselves.

    1980s era 100km search is very good. Considering MIG-31 was at most 200km at that was using PESA.

    APG-73 from late 90s atleast has 160 km range and RMAF considered BARS superior to it from 2001 almost equal to future APG-79.

    there is nothing wrong with Zhuk-MSF range as it wast fully developed. and 180km is not a bad range considering it is decade old technology.

    I don’t know what you are trying to say here.

    And if you believe Western or (gasp!) Chinese radars are any different you have another think coming. It has simply come to the point where the Russians are so eager to sell their stuff that we have more detailed performance specifications for their radars compared to most competitors from other countries.

    BTW, one of the reasons why the N-001 couldn’t quite match the maximum detection range quoted for the APG-63 is that it had no such thing as a VS mode.

    Not sure what you are trying to say here, but N-001 clearly has VS mode from the link I provided. Yes, other radars also have Velocity search mode or extended range search mode, which when quoted, can cause confusion. I’m stating that the range mentioned for 400 km vs 3 sqm target and 90 km vs 0.01 sqm target are range in VS or the Russian version of Extended range search mode.

    It is not just the question of power, but also of gain, losses , dwell time and signal processing. NIIP and Phazotrons approaches can be significantly different, and Phaza’s public literature implies they dont know much about NIIPs work and have been focused differently.

    Zhuk MSF never went into production. Unfortunately those figures are Phazas brochure speak.

    Also the N001 figures are actually for different modes than ones quoted..

    well, that’s what China got from Russia with su-27. And they got the ones originally intended for Russian Air Force, so they weren’t downgraded or anything.

    Also, I did a little thought experiment on this. It does seem possible that some kind of extended range search by Irbis radar can reach 400 km vs 3 sqm target. Because if they tested that it can actually lock onto 0.1 sqm targets from 100 km out. That would mean locking onto 3 sqm targets from 234 km out. Which is about 60% of the velocity search (or ERS) mode. Which really is comparable to Zhuk-MSF’s ratio of 150 km in TWS to 245 km in VS mode.

    Well since the last boom (052B & C and 054s) there have been bit quite a pause in the new-chinese-large-surface-ship-revealed front…

    looked like they waited until after the olympics to really start with the surface ship again. So far this year, all we saw were Yuans and medical ships. Clearly, China was careful to not trot out large surface ships to scare the world.

    I would love to see Chinese 5th generation in 2011. Advance 4th generation makes alot of difference from Superior acceleration, altitude, range, weopon stations flexibility, 150 sensors on airframe, long time for engines and hence better uptime.

    waiting for, not getting it. We’ve already covered this, with AWACs, other fighters around and ground stations networked together. The performance of an individual fighter’s radar is not as important. 5th generation birds offer the element of stealth that 4th generation birds don’t have.

    it is certainly not velocity search. these are old data. Irbis can guide 4 semi-active BVR at range greater than 300Km. lock on range may well be above 400km.

    lol, believe what you must. Consider this, N-001 vs 3sqm targets is listed by Chinese sources as having a search range of 80-100km, tracking range of 60 km and lock-on range of 40 km.
    and you can check here http://www.aeronautics.ru/archive/vvs/su30-01.htm

    Radar: NIIP N001 Myech (`Slot Back’) coherent pulse Doppler look-down/shoot-down radar, detection range up to 54 n miles (100 km; 62 miles), tracking range 35 n miles (65 km; 40 miles); ability to track 10 targets and engage two simultaneously offered, but probably not available on current in-service aircraft.

    you are basically saying that Irbis will have 10 times the lock-on range of N-001. I’m speechless.

    an interesting case to consider is Zhuk-MSF.
    Designed to have a peak power of 8 kW and average power of 2-3 kW
    Against a fighter size target (I’m presuming 5 sqm here)
    velocity mode search range is 245 km
    RWS mode, detection range in lock-up face on is 180 km, tailing is 90 km, look down face on is 130 km, tailing is 60 km.
    TWS mode detection range is 150 km.
    Vs large targets like AWACS and tankers, the tracking range is 300 km.

    I would think that you can do some estimation of Irbis’s performance based on this. If we base it on the brochure data, then the power of Irbis is 2 to 2.5 times that of Zhuk-MSF. If we take the quadric root of that, you get about 1.2 to 1.25 gain in range.

    I think that despite the great strides that the Chinese have acheived to this date with the J-11B indigination program the are still very much “in the market” for new hi-tech component and techology transfers from the Russian Industry. It may be a small order 48 aircraft, or something like this, but it is sure to be purchased along with the more traditional local J-11.

    Do I make any sense?

    Regards,

    Hammer

    Russia has about the same chance of selling su-35 to China as China does selling J-11s to Russia. Even if they buy into this Su-35 sales pitch and believe it’s “much better” than the domestic J-11, they wouldn’t buy it. Why not? Consider operating these 2 in a network with AWACS, other fighters and ground based radar in any kind of war scenario against America. Neither fighter are likely to dramatically increase the combat capability against a super hornet/E-2 airwing or what USAF would send out.

    If Su-35 came out in 2004 and was delivered to China starting in 2006, it would be a different story, but by 2011, China will be waiting for a 5th generation fighter rather than a glorified 4th generation fighter. No matter how many + they add to the end of 4, it’s still a 4th gen fighter.

    I’m speaking out from official NIIP numbers for export model of Irbis. That’s 90 km detection of 0.01m2 target, head on. I don’t want to get into discussion about F-22’s RCS, but it ain’t perfect. So there must be a relative angle from Flanker’s viewpoint where Raptor’s RCS comes to (or above) 0.01m2.

    don’t just use that number from the face of it. Other than my previous assertion that Chinese testing determined it didn’t achieve that kind of range. A lot of the maximum detection range you read for these radar are for the so called velocity search mode. The tracking range in RWS mode is less than that and the lock-on range is even less.

    i really don’t think US has any trouble getting a supersonic missile if it really wanted one.

    Take a look at this article, if they can create something that simulates club, they should have no problem developing a supersonic missile.

    Aug. 28 (Bloomberg) — Alliant Techsystems Inc., the largest
    maker of solid rocket motors, will produce at least 50 supersonic
    targets for the U.S. Navy to test defenses against the Sizzler,
    China’s most capable anti-ship missile, a service official said.
    The Navy awarded Alliant the initial $97 million development
    contract for the Multi-Stage Supersonic Target last week, which
    includes targets for seven tests. It also will get the production
    contract as of 2013, Captain Pat Buckley, the Navy’s program
    manager for targets and decoys, said in an interview today.
    Alliant was selected over competitors including Raytheon Co.
    and the first target missiles are expected to be delivered in
    2014, Buckley said. Minneapolis-based Alliant sees the potential
    to build as many as 200 missiles over a decade at a cost of about
    $2 million each, Jack Cronin, its president of mission systems,
    said in an interview today.
    “We are hoping that ATK and their team will develop a
    product that meets our requirements at the lowest possible
    cost,” Buckley said.
    China purchased the Sizzler from Russia and already has
    deployed it on at least eight Kilo-class diesel submarines, which
    also were bought from Russia, the Pentagon said in its report on
    the Chinese military released March 3.
    The Sizzler is one of the “Threat D” family of anti-ship
    missiles the Alliant effort will focus on, Buckley said. The
    Sizzler flies at subsonic speeds until within 10 nautical miles
    of a target. It then releases a rocket-propelled warhead that
    accelerates to three times the speed of sound, flying no more
    than 10 meters (33 feet) above sea level, making it difficult to
    defend against.

    A Moving Target

    The missiles Alliant is building will give the Navy
    supersonic targets to try to track and shoot down.
    Buckley said he does not yet have an estimate yet for the
    production contract’s eventual value but the plan would be to
    build 10 target missiles a year for five years. The final number
    to be produced is “totally unknown at this time” and will be
    determined based on the military’s needs. The number of 50 “was
    a ballpark swag” based on the test plans for vessels in
    development, he said.
    “There is a class of extremely advanced cruise missiles
    that our ships are going to have to thwart,” Alliant’s Cronin
    said. “Right now there is no way to test these ships against the
    threats because they are that advanced. This system will more
    than do that.”

    Yeah but I heard a rumor that someone flew over Dalian in an airliner and the Varyag was absent.

    yeah, I think that was invalidated.

    Is Varyag still at Dalian?

    you know, a while back, some people at SDF became convinced that they did work on the island. After that, we got a bunch of varyag photos from Dalian that had no work done to the island. So, we are not sure if those are old photos or current photos.

    Everyone seems to be pretty certain that DDGs will indeed be pursued and instead of spreading my ususal cynicism, I’m infact blutly resting on these claims as I’m eager to see what the next DDG from china will be like.

    I once asked interesting question, packed with my usual cynicism however at that time about the chinese ability to design gas turbine powered DDGs with satisfactory performance. By that I ment the small and cauntious quantativical ammount of the 052 series. First two then back to old steamers and then two again and back to old steam-powered ships again.
    I was, like ususally mainly claimed to be just ranting with the tag that “I just hate china”, but in the mist some slight reasonable arguments did rose. Many belived that the reason why only two seccond batch 052s (052b/C) were build was that the production facilities were shifted to another shipyard. I my inturperation was that chinese were not satisfied with the performance of the CODAG propulsion build around the Ukrainian Gas turbines. IMO it’s too small for the ships of that size. So to me it seemed as there still weren’t no proper domestical large size marine gas turbines availble and thus the production of these ships were halted.

    Now since then (this being about year ago or so) there have been optimistic reports about chinese procediings in gas turbine field so thus these new DDGs are really a bench mark: Will they be fitted with domestic or imported (Urkainian) gas turbines? Will they still be CODAG or peraps COGAG/GOG?
    What if the DDGs are like someone said, “051Ds” eg. steam powered? Or perhaps all diesel powered (not so unlikely as it may first sound)

    Like I said I’m eagerly waiting to see what will come up with this. At this time I promise to be far more optimistic than usual;):cool:

    if 051 series continues, I think it will just be more steam powered ships. As for Chinese gas turbines, they are still going to be localized GT-25000. The domestically designed gas turbines probably need another 3 years before they are ready to fit into ships.

    New AFM has PAF Chief interview in which he has outlined PAF fleet requirements for 2015 fleet. according to this interview By 2015, PAF will comprise 240 JF-17, 60 F-16’s, 40 FC-20’s (PAF version of J-10), 50 F-7PG’s, 4 SAAB Erieye, 4 ZDK-03 (PAF version of Y-8), 4 IL-78 Midas. FC-20 order should be confirmed in next 12 months or so, whilst final configuration is worked out. Current J-10 technology is not upto PAF requirements and as the platform natures, PAF hopes to include western equipment in the J-10, thereby signifying a different version from PLAAF J-10, which will be known as FC-20 in PAF service. FC-20 will not be required to have any conformal fuel tanks, as it has sufficient internal fuel capacity as well as AAR by Il-78 Midas tankers. Although AESA radar would be nice to have, there is no confirmation if this will be made available to PAF.

    As I mentioned in PDF, the part about current J-10 technology is not upto PAF requirements is a misnomer. PAF is looking for the modified J-10 that just flew recently and will be entering service in the near future. Since they are looking at that next block, the current one is obviously not up to their requirements. And looking at other transcripts, it looks like the part about not up to PAF requirements is also overstated.

    J-9 as originally defined in the mid 1960s (before the double 27 and double 26 requirements) was to be able to out dogfight a F-4 and intercept the F-105 and B-58 in all weather conditions, and have significantly greater combat radius than the MiG-21. The J-9 was the competitor to the J-8, and the later won the competition, primarily due to the unreliable WS-6 turbofan engine the J-9 was designed around.

    actually, it was mainly because J-9 was too ambitious for China at that time. Even for J-10, they had contingency plans for a turbojet engine.

    This is Insititute 611/CAC’s J-9 project. It started in 1970, quited in 1980, lasted 10 years. J-9 was a failed project,however,by the J9 project, Insititute 611 got rich experience of canard layout and delta wing. I’d like to say J10 is a successor of J-9. Here is a wind tunnel mode of J-9.http://i0.sinaimg.cn/jc/p/2008-08-07/U1335P27T1D515312F3DT20080807082504.jpg

    a lot of the requirements for J-10 supposedly derived from J-9 (although I guess aiming less for the fast speed and more for maneuverability). It’d be nice to get the full J-9 requirements, so we can get a better idea of J-10’s requirements.

    Hmmm I’m a former SAM technician and I never thought about whether SAMs could counter a TLAM strike eh?. The word ‘saturation’ means, in this context, to fire more weapons than the opponent can defeat. It is a dramatically successful tactic. The SAMs arrayed by the PRC are amongst the best in the world, they, like all SAMs though, have x number of ready-to-fire rounds on the launchers. If you fire x+5 TLAMs at that site then, barring freak incident, you destroy the site.

    If you mix in a few Super Hornets worth of 300km ranged ITALDs with the x-5 TLAM strike you guarantee saturation. It would require a lot of TLAM’s, several hundred in fact to just open up SAM defences and knock out a few airfields, but the USN has no shortage of Mk41 cells and hitting MPA airfields, OTH sites, etc would be worth the expense.

    Just to butt in a little bit, but a while back I read from a pretty good source that China was preparing 5000 HQ-9 missiles at that time. Of course, it’s not fully deployed yet, but it definitely sounded like they were preparing for some serious pounding against the 4 major civilian areas and military regions. If you add the S-300, HQ-12, HQ-7, all the anti-aircraft artillery and mobile air defense units, you seriously need a lot of missiles.

    So Alaska is less sovereign than Guam, Hawaii or Washington? What’s important in that article is that the US recognises and adheres to the 12 mile boundary, and it certainly does not have any ridiculous ‘200 nm shoot-down zone’ conceived by cows. Unauthorised planes getting too close to the 12 mile boundary get escorted out. Only after an incursion and failure to heed repeated warnings and maybe even warning shots would we ever see a shootdown. If armed force was so cavalierly resorted to we would see a sunken Han class sub, which was caught in Japanese territorial waters.

    Does this guy get a warning at all for basically calling me a cow, when I was just asking a question? And the question wasn’t even for him.
