    Not good enough, First source is for the pre production array which is not fully populated (Zhuk AE) second is of APG 65. :rolleyes:

    Well, if you can find me the specs of the production model, we can discuss it.
    As for the second part there, the point of the matter is that the APG-79’s range is >3 times that of the APG-73, which is in turn superior to the APG-65’s. What you can infer is that whatever figure mentioned for the APG-65 is < 1/3 of the APG-79s performance. In terms of overall performance, the APG-79s is suppposed to be >10x as capable as the APG-73.

    I’ll say it again. Radio waves are radio waves. There’s little more to it.

    They are directional, and an RWR with powerful enough processing, especially one that knows the basic actions of LPI, would in all likelihood be able to pick up the LPI signal given enough time.

    And you’re missing the point still. The way LPI works is by not looking like a radar, to a RWR. Are you suggesting that the simple solution is to just look for everything that doesn’t look like a radar? Modern RWR/ECM systems have digital threat libraries that they compare incoming signals with. They also filter out signals that don’t appear to be threats/background noise, etc… to cut down on false alarms. LPI works by using very short bursts, with discreet beams, using random and very rapidly changing freqs/waveforms, etc…, so it’s not a simple task of merely raising the sensitivity. That’s not to say it’s impossible to detect, but it’s by no means guaranteed to be something that can be taken for granted.

    Without meaning to get too political, there are many other governments with “extremist” ideologies that manage to have very sane foreign and defence policies….

    Yes, but they aren’t necessarily working on nuclear capabilities, or threatening to wipe out other countries(or waiting for the 12th Imam for that matter).

    I totally take that point Jonesy, but Iran was targetted in Iran-Iraq war, I genuienly think we overestimate Irans aggresive desires. They may have problems with many nations but they are not so stupid to try and make everyone their enemy.

    One would certainly hope so, but when you’re dealing with a government that has extremist ideologies, you can’t assume that they have the same concerns, as folks with cooler heads.

    The -D model passed its 7th test 1 year ago. Fielded? Are you insane?

    Page 12
    http://www.defense.gov/news/d20100201afslides.pdf

    The Zhuk-AE shown on that brochure/stand is the one with less than 1000 T/R modules. It’s a prototype / proof-of-concept piece

    I do not recall any mention of modes for the unit yet.

    So is there a production representative model yet?

    EA capabilities are standard.

    Source?

    There has been no mention of LPI in anything I have read, but then again, the unit’s capabilities have not been revealed as of yet.

    Well, once the capabilities are revealed, we can have a more meaningful discussion.

    200KM detection range vs 1 – 3m2 I believe. I’ll look it up and let you know.

    Most Russian range specs that I’ve seen are vs. a 3m^2 target.

    ATFLIR is my professional opinion, of course. :rolleyes: It’s mounted under the plane, how effective for A2A do you think it is LOL?[/QUOTE]

    It would depend on the FOV that it’s capable of scanning(I don’t suppose you have the elevation and azimuth limits?), and the altitude of the SH(which presumably for A2A missions would be at a high altitude).

    Didn’t a ranking US General state some time back that the UAE AIr Force with its Blk 60 Vipers could overpower its Iranian counterpart all by its lonesome? Aside from the UAE, there’s the Saudi Fleet of British and US jets and now Oman building up its air force. Not to forget Israel of course. And the US would figure to get involved in any future conflict in all likelihood.

    The IAF would have a very dramatic few days of existence in any major conflict but there’s no doubting the outcome. That’s why they’re so keen to develop their nuke capability.. its their trump card offsetting (in their mind) any weakness they have in conventional forces.

    Their best course of action would be to be a better neighbor, and learn how to play well with the rest of the world.

    and for comparison(you’ll note that the figure is for the APG-65- the APG-79’s range is >3 times this performance)

    .What is behind J-7 hotdog? A poster that makes fun of the Chinese Mig21 (J7) by calling it a hotdog. That same plane is doing 4 decades service with the Indian Airforce. Both the Mig21 and its derivatives have shown impressive records. Even these days the planes is a remarkable one. Anyway back to the topic. It beats me why someone should see the reasons of buying Typhoons by Oman should be relates to Bulgaria or Pakistani harbour called Gwadar. I have seen several posters moving towards good posting but unfortunately some do not follow. I have read Oman buys Insas. Insas is produced by India. I see no reason making strange remarks about that. I hope our friend here moves towards related and informative postings and not the usual anti Pakistan remark.

    You’re familiar with sarcasm right?

    The Russian range figures are for a 3 sq m RCS target. Against a 1 sq m target, the APG-79 has a maximum detection range against a high-aspect target of 110 km in both look-up or look-down modes.

    That’s a very conservative figure for the APG-79.

    ATFLIR is garbage compared to the IRST on the nose for A2A purposes. The limited FOV itself just sinks that entire proposition.

    The AIM-120C7 is right in the RVV-SD ballpark.

    The AIM-120D isn’t is about as operational as the 180KM Russian missile. So that’s irrelevant.

    ———-

    Also, the Zhuk-AE-35 will have a tracking ability of 60 targets with a range of 200KM, well within APG-79 “grade” capability.

    The -D model is what is currently being fielded, so I’m not sure what’s irrelevant about it.

    As for the Zhuk radar, do you have another link other than the one that was provided? What size target does it have a 200km detection range? Can it operate in A2A and A2G modes simultaneously? Does it have EA capabilities? Does it have LPI modes?

    Do you have some info about the ATFLIR being garbage, or is that just your “professional” opinion about it?

    How many T/R does APG 79 have ? The Production Zhuk AE will have 1064 T/Rs with each module having significantly more power (Gallium Nitride T/R modules).

    >1200 T/R modules

    R VV AE to start with then to have RVV SD to follow on. R73 E and then R-VV MD or in India’s case Python 5 which is as good if not better than AIM 9X it already has LOAL which only the Second generation AIM 9x will get. The 29 K has the added advantage of having IRST.

    Like I said, the SH has ATFLIR(which serves as an IRST for A2A or A2G). The R-74 may have a longer range than the -9X, but the -120C7/D have longer ranges than R VV AE/ RVV SD(respectively), which the Mig would have to survive before getting into WVR.

    Some specs for Zhuk-A(E)here …

    http://img291.imageshack.us/i/zhukaemj2.jpg/

    Again , anything like this kinda of data on the APG-79 , rather than claims ?:)

    Hmm, 130km head on detection of a 3m^2 target. That’s ~APG-65 performance, or marginally better. The APG-79 has >3 times the range of the APG-73(which is superior to the APG-65). I didn’t see any mention of simultaneous A2A and A2G modes, much less EA, Elint, etc… The APG-79 can track more targets simultaneously as well.

    Do you have some datas that show the APG-79 is /will be indeed better than Zhuk-A?

    Do you have some datas that show the SH is indeed haveing a lower RCS than the Mig-29K ?

    🙂

    Well unless Mig has secretly lowered the RCS by an order of magnitude, then I’m going on the assumption that the -29K is in the same RCS ballpark as an F-16(or worse), which would mean that the SH has the advantage. As for the APG-79 vs. Zhuk comparison- can any of you even show me a working, representative model, and some specifications, or am I going to be constantly asked to disprove a negative?

    RVV-SD , an upgraded R-77, max range 110km, thoroughly upgraded electronics.

    RVV-MD , an upgraded R-73 , more exactly an upgraded K-74M, max range 40km,and up -to -date seeker and electronics…

    Both these misiles were shown at MAKS-2009.

    Neither of which gives the -29K first shot against a SH, which has a lower RCS, better radar, and -120C7/D.

    APG 79 vs ZHUK AE – We don’t know which is superior wait till the latter is in production and a bit mature.

    Well we already know that the T/R count will be lower, and we’ll just have to see the level of sensor fusion, and mode options available

    JHMCS – Hardly superior to Topsight (Topowl, waterverl)

    In what respect?

    better short and long range AAMS – New Russian AAMs will take away the advantage, R73 is still nearly as capable as other SRAAMs.

    Which new long range AAM is the -29K going to carry(and more importantly which aircraft will have the advantage of first look first shoot)? The R-73 is a good missile, but doesn’t have nearly the capability of the -9X or ASRAAM.
