    I don’t know.. I personally find it quite hard to locate (moving) targets which would be worth using a $120k missile. Tanks are quite rare and destroying Toyota trucks by tossing Ferraris on them is hardly a sensible approach.. πŸ™‚

    The war in Syria is not the only war these helicopters might get used in. So, against an opponent with modern or even just decent SHORAD capabilities, a fire and forget missile’s price is much cheaper than that of a lost assault helicopter and it’s crew.

    ‘ΡƒΡ€-a’ means ‘Guided Missile – Ataka’. Auto-tracking mode is indicated as ‘AC'(you can see it in the bottom line of button indicators) and it’s working in the video with two stationary trucks while in the video with the moving one it’s disabled which means that operator is tracking that moving truck manually.

    Thanks for the info about the ‘yp-a’ meaning. I figured out that the moving truck was tracked manually as it can be told by the tracking gate shape (solid line).

    It’s interesting that they use ‘yp-a’; in the Ka-50 the weapon type was indicated on a separate panel rather than on the targeting screen. But, the ATGM (Vikhr in that case) was marked as ‘пс’ IIRC.

    I think the first video is the following of the second video. I don’t know, why operator didn’t use auto tracker as helicopter fly quite fast at 270 km/h and at range of 5 km, where missile fly quite some time to the target and it is more difficult to track target manually, what is seen in the second truck in the second video, where operator dance with the cross around the target and with that miss it.

    On a second look, I’d say that some form of auto-tracking is used when the TD gate is released (i.e. is not a solid line square) since it seems to track the missile smoke contrast and veer off the target during the engagement of the second stationary truck. During the engagement of the first truck, the operator seems to override it (as the TD becomes solid) while the missile is flying towards its target so it remains put.

    I wonder if the ‘ΡƒΡ€-a’ on the right relates to this tracking mode perhaps? In the DCS Ka-50 simulation, there are separate marks for target tracking to indicate whether the auto track has locked onto the target image (‘TA’)or if it’s just ground stabilized (‘Ρ‚Π³’), but I guess those show when the automatic tracking master mode is used; there’s nothing like ‘ΡƒΡ€-Π°’ there, but there is a ‘py’ WCS master mode which means manual mode in which the tracking gate size is not adjusted automatically and there is no target lead calculation. So, it might stand for some form of mixed control (y) manual (p) and automatic (a) targeting mode where the tracking gate size is adjusted manually (hence why they are not changing and the target tracking is suboptimal).

    I don’t think they should remove the Metels. That’s a good capability to have. And you lose that. I’d rather add to the capability if it’s not redundant than replace things. Which is why I advocated replacement of the torpedo tubes. I can see their utility, but that same utility could be served by the Metels. Likewise, the Kh-35s could be bolstered by firing Metels at surface ships. I like replacing the 100mm.

    But, those missiles are long out of production and the remaining stocks are supposedly small. The Metels should thus best be replaced by some modern ASM’s or dual-purpose cruise missiles if the destroyers will be kept in service for some time in the future. The Metel ASW capability is anyway replaced by the SS-N-15’s (or 16’s even?) fired from the torpedo tubes.

    If modernization is an option, the bigger issue is the lack of a medium range SAM system which would make for a better use of the top turret space πŸ™‚

    2nd missed right behind the truck, voice indicates as much. Hard to say what happens with third target, by the voice they clearly intend to engage it, but video sadly cuts off. No problem hitting the mover in the first video, so I’d guess they engaged it as well.

    In these vids it looks like the target designator is not tracking the targets automatically, but that the pilot is doing it manually with stabilization only? This can be seen clearly when the moving target is tracked since the TD box is in the slewing mode. In case of the other two static trucks, it seems that the TD only gets ground stabilized when released from slewing, rather than establishing lock on to target. Perhaps there’s not enough contrast for reliable auto tracking so they prefer to use manual control?

    Personally I’d delete the after pair of gatlings and site a single quad angled outboard on each beam there before losing those torpedo tubes….if the Metel bins had to stay that is.

    Those mini ledges looks pretty tight and might have weight limits. The logical thing would be to replace the obsolete Metel launchers, but otherwise, why not remove the top 100mm gun? Plenty of space there for like whatever.

    I only have seen few operational MiG-31BMs carrying armament.. All of them have baseline R-33 missiles, usually carried in pairs using asymmetric load config.
    Looks like the R-33S is pretty elusive, not much info about it, either..

    Same here, but I suppose it might be due to it entering production roughly around the time of the breakup of the Soviet Union so the numbers produced were probably limited and the lack of spare parts could be a problem as well so it’s questionable how many (if any) remain operational.

    This is all guesswork of course since there’s little to no information available. Perhaps the Russian forums offer some insight into the R-33S capabilities and status?

    I don’t think I have ever seen even an MiG-31BM carrying the R-33S. Do you have any pics?

    I never implied that I saw it on a BM; just mentioned the MiG-31B specifically as the R-33S was supposed to have been a part of that upgrade.

    Berkut, do we know details about RVV-BD trials / introduction date? AFAIR it was marketed as LR-AAM option for (then called) Su-35BM in it’s export brochures. I guess some of it might be public.
    R-33S is more than enough until then. It’s got 230 km of theoretical range. R-37 1994 test was 280 km. But Su-30 took over at some point because SBI-16M wasn’t fully operational.

    I don’t think I’ve seen photos of R-33S on a MiG-31B yet. IIRC from a diagram, it is noticeably different (e.g. has a set of small wings added up front). Since it was a rather late project (just as the USSR was collapsing), I suppose it wasn’t built in large numbers?

    Edit: there’s actually a live image showing it:

    The radar has been upgraded to Zaslon-M standard, but its diameter of 1.1m has been retained, for example.. Around sixty MiG-31BM are in existence, AFAIK..

    The updated radar retained the old antenna and is referred to as Zaslon-AM AFAIK (as the Zaslon-M was the older one used for the MiG-31M project which had a new larger antenna).

    The MiG-31 got its new engine to allow operating it against low-flying threats, like cruise missile, doing so at subsonic speed below medium heights for its look down mode capable radar. Operating there or at speeds over Mach 2, both takes its toll in flight-hours left.

    Sorry, I’m pretty slow these days. What was the point you were trying to make (i.e. how does this relate to my post)?

    Let’s try to use logic:
    We know that actually Russia is renovating its whole armed forces at a great expense with a quite ambitious program.
    Now, in the middle of such an effort they choose to spend money into renovating a plane with structural limits that practically made it useless for the primary role it was designed for, while they have a wide array of more modern planes still in production…
    Sound quite absurd to me, also because they have just started a program that would eventually substitute it.

    What structural limits made it useless as an interceptor? Aged canopies? They obviously think it’s very unique and important to them, otherwise they wouldn’t scramble to upgrade as many as they viably can and start worrying about its successor.

    So, IMHO they have decided to renovate just the planes in better conditions and would use the others for spare parts.
    It would cost them way less than buying a whole new plane and so fit into the effort made.
    It would eventually also include canopies, even if I consider quite incredible that they can have just lost the knowledge to made them.
    Maybe they have not the assembly line anymore, but given the numbers involved they can even made them one by one on a bench.

    The canopies required a material made by using a special technology which was seemingly not needed at least since the end of the MiG-31 production which was like 20+ years ago (so probably even more for canopies). Why is it surprising that the capacity to make more is not readily available?

    Doesn’t it have 9 hardpoints in total, four on each wing?

    Yes, hence my question. I don’t see what’s confusing here?

    Also, i can’t understand why VKS has not fielded twin launchers for A2A munitions yet. It isn’t really needed for flankers, but what about Migs?

    Is there a need for those given its size and role? Besides, which missiles did you have in mind? Given those rear control surfaces I don’t see the R-77 as a candidate for rail launching.

    I mean, having 6 hardpoints under wings – it’s pretty hard for me to imagine what types of munitions could compose these five tonnes of combat payload if only one EFT has been installed. 3 EFT + 4 munitions worth of 5t is the only real configuration for MIG-29/35 IMO.

    6 hardpoints?

    The only thing, related to the “glass problem”, that i managed to find is a short conversation in the comments section under this photo: http://russianplanes.net/id157916

    And i didn’t find any news about some production of canopies or news about speed-limit has been lifted. Honestly, i’m sure i would be aware of that, if some official news have been released. So i presume this info is based on some rumours and speculations in our Russian aerospace-Web segment.

    Then I probably remember it wrong as I couldn’t find anything now, but some posts claiming that the BSM canopies are not actually entirely newly produced, but are reusing some old Soviet-made stockpiles of this special material needed.
