    I’d say it’s half a motor section of a GQM-163 combined with a HARM front.

    Hmmm, the GQM has a 13.5 inches diammeter, while the HARM is 10; from the picture posted it seems that the diammeter is contant. So, it must be a 10 inches ramjet…

    A lot of that had to do with the radars being shut off while the ARMs were in flight. New model HARMs have a much improved ability to maintain the emitter’s location in their guidance system and greatly increase the chances of striking a target that has ceased to emit RF energy. Besides, in the SEAD world, every single HARM fired that caused the radar to switch off was a successful shot even if the radar survived as it negated that radar’s ability to do its job. The press and the armchair analysts seem to forget that when they bring Kosovo up in what appears to be an attempt to make the NATO air arm look inept.

    That’s exactly what I said, that the HARM still did their job by forcing the Serbs to turn-off the radars. I just wanted to point to Zare that shoting an AWACS from 300 km is, to put it politely, a verv, very, very difficult job.

    Actually NO

    Both Eurofighter GMBH and, specially, Dassault have claimed that they have that capability for years.
    Has a matter of fact there´s a very big text in the Greek “Diplomacy and Defense” (or something like that) of an exercise in 2006 in wich the Greek pilots flying Block50+ Viper´s mentioned, several times, that the Rafales M were picking AND TARGETING them on a RWR passive mode using Spectra. One of them (HAF pilot) mentioned a detection range of 200 km´s…
    The RAFALE has been fielding a very precise RWR in the air to air mode for several years, and i would be very, very cautious in claiming any superiority of the ALR 67 (V)4 over the European systems…

    Cheers

    Actually NO:) I didn’t say that the Rafale Spectra (not so shure about the DASS in its present configuration) can’t measure range; however, it’s not the RWR that would do that, but the ESM, so no matter how precise the RWR on Rafale is, it still can’t do the range. Only if Spectra has an ESM, it will be able to do it.

    What i’ve questioned was the Su 35 being able to measure range, considering that outside EW planes, there are few fighters that can doi that.

    You have to take into account that many missiles were launched in pre-emptive mode at supposed coordinates.

    I know. Even with this lame percentage the HARM still did the job, by forcing the Serbs to turn off the radards. Nevertheless, hitting a fixed ground target it’s a piece of cake vs. attempting to hit a target flying high ( 10,000m) with 0.9 M at 300 km.

    I wouldn’t bet on that. The ESM equippment of newer fighters is able to range emitters as well. These capabilities are known for the F-22, Rafale and Eurofighter and even normal F/A-18E/F (not only EA-18G). The Su-35 features ESM as well and I wouldn’t exclude the possibility that this system has ranging capabilities.
    For the rest of your post I can only agree.

    With all due respect, I disagree. The newest RWR on the basic SH is the ALR 67 (V)4. It’s a full digital one, probably the best in its class (the same technology is in the ALR 69 (V)A presently installed on the F 16 blk 40/50). However, it still not produce the range. For this you need either internal ESM found on dedicated A/C (F 18G) or poded version (F 16 CJ+Harm Trageting System); equally two ALR 67, as well as 69 will be able in the near future to triangulate the position of the enemy radar (airborne or ground) using these advanced RWRs and Link 16. Aside the F 22 the only fighter that is officially known to be able to measure the range is the F16 blk. 60 for UAE.

    @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. 🙂

    This is what i call almost religious fate!

    But (and I asked this question many times on that forum) do you know that in Kossovo, US and allies fired hundreds oh anti radiation missiles (HARM, ALARM) on Serb radars. These missiles were fired against ground, imobile targets, from above at distances of around 40-50 km. Still, less than 10 % hit their targets!

    However, according to some naive guys that give the Russian SciFi brochures 100 % credit, there is no doubt that a “mighty” 172 will have no problems in finding, tracking and destroying an AWACS flying at 900 km/h from 300 km !!!!!!!!!!!!!!!

    No on a more serious note:

    A Su 35 won’t be able to find the range to an AWACS; no doubt the bearing would be easy to find; however, finding range requires some more sophisticated gear, found on a few EW planes (EA 6, F 18G, F 16 CJ with HTS) I don’t doubt that Russain dedicated EW planes have the same capability, but not a fighter like Su 35.

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

    :diablo: yes, it going to wait for the Russian missile:p

    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).

    wrong again; the first rounds from the Initial Operational capability has already been delivered, as anyone can see on Raytheon (the manufacturer) site http://www.prnewswire.com/cgi-bin/micro_stories.pl?ACCT=149999&TICK=RTN&STORY=/www/story/10-06-2006/0004446872&EDATE=Oct+6,+2006

    This contract supplements the Lot 20A effort awarded in February 2006
    and, in addition to funding AIM-120C7 missiles, it also includes the first
    production deliveries of AIM-120D missiles from December 2007 through
    January 2009.

    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

    Do you really believe that a Su 35 will be able to track a F 22 from 70 km????

    and a Raptor is $120 mil which is about the same considering the capabilities…

    You know, considering how much money the USAF is paying per plane for that darn thing, it honestly wouldn’t surprise me if it could.

    Forget this crap; the flyaway price is about the same for both planes…

    I have been off this thread for a moment and now I cannot believe my eyes. During the Cold War times Russians were said to be able to blow up the entire planet 5 times (or is it just 2-3 times now?), but judging by the reponses here it looks like smashing one US aircraft carrier is still an unreachable task for them. 😉

    Weird….

    With nuclear missiles, no one can argue; with convetional ones…that’s diffcult

    I think it was a dark master plan to deceive the Americans. Russians have been producing the otherwise utterly meaningless grid fins for years on SS-12, SS-21, SS-25 or R-77 and patiently waited until those stupid yanks finally copy the design on GBU-43/B, making another US design completely useless. Guess what, the plan worked! 😎

    http://www.aerospaceweb.org/question/weapons/control/gbu43-grid-fin.jpg

    So, in your opinion, an A-A missile has the same requirement as a bomb kit?

    The official figure for R77 is 50 km for fighter target 80 km for large target.

    I know; in fact the ranges of early(non-loft) AMRAAM and R 77 must be the same; the heavier (~10kg) Russian engine is compensated by the draggier lattices. But the figures quoted by various “reliable” sources (from Carlo Kopp articles describing the imminent attack of Australia by hordes of Chinese Flankers :p to various Veniks lurking on aviation forums) are 90-100 km :p

    PAK-FA engine test-bed (quite literally).

    Any aviation fan should recognize the F 119.

    Put AN/SPY-1D of the last baselines (that’s a PESA one!) against any “stealth” blub…

    If it flies it dies :diablo:

    Yeah, but it would require 4 MW of power. A little heavy to move it from a burke destroyer to a Su 35 :diablo:

    Zdarova hexpop, from the sources you mention can we assume:

    PAK-FA weapons:
    http://www.ato.ru/rus/cis/archive/17-2007/def/def3/

    After reading Piotr Butowski article on the link posted by Otaku, I wonder:

    -the Russians are giving up their “famous” lattice fins used in R 77, replacing them with conventional ones ?????? OMG!!! So this revered aerodinamic design is not so great ????? Blasphemy!! :p :p :p

    – the “new” K-77-1 (Izdeliye 170-1) has a range 2-3.5 times bigger than the curent R-77 (Izdeliye 170), while only matching the AIM 120 D ????? :p :p :p OMG, OMG !!!!!! So the 90 km range trumpeted for the R 77 is nothing more than Russianfans wet dreams ? :diablo:

    – how are they going to put a couple of K 172 in the internal wepons bay of the PAK-FA, while still not increasing its size to a T 22 ???

    Well, erm, Star that appears to be a newspaper clipping dated some 7 years ago that repeats the advertising material thats been around for a while. It actually, IIRC, predates the ESSM/Vandal testing.

    So….since that newspaper piece we find that supersonic skimming is really not the invulnerable attack profile it was advertised as being. We also find that, to get its 300km range, Onyx must fly an altitude cruise phase exposing it nice, early, detection by its target vessel. In otherwords, since your advertising piece from Itar-Tass was published, we find that Onyx is not as impressive as we were led to believe.

    If you can Star just be objective for a few minutes and tell me you can see the difference between the report of the official testing of a weapon system in a representative threat environment and a newspaper piece that, pretty much, regurgitates the manufacturers advertising?.

    You can add a other problem with supersonic ASMs; in the final phase, considering that they would escape the Standards and the ESSMs, they travel low; the result of traveling with high speed through high desity air is that they became red-hot (actually in night they are visible without IR equipment!) For the guiding system of the RAM system (Ku radar + FLIR) that a meaty target to direct the Sidewinder-derived missile…
