    I was checking the list of all electronics on the ship and I noticed six radars: Furke-E, Zaslon, Monument-A, MR for navigation, Puma for fire control and even Poliment (btw this means that it has Poliment-Redut air defense with 300 km range - equal to Gorshkov class). Does anyone know if all of them are AESA?
    Thats a mish-mash of the various versions & apparently confusion between Poliment-Redut on Gorshkov with what should be described as Furke-Redut on 20381s.

    Furke is an S-band PESA based on the Pantsir-S1 search radar. (small dome at top of mast)
    Monument is a passive/active OTH anti-ship radar (in the front of the mast)
    Puma is an AESA (rectangle on top of the bridge)


    Gremy has Zaslon system replacing those separate radars with an integrated system of new-gen 4-panel fixed equivalents, active X-, S-band, passive L-, S-, C-, X-, Ku (apparently still Furke but at least suplemented by the new X-band AESA, could be new gen though?)

    http://www.russiadefence.net/t2547p350-russian-radar-systems#198456

    Any idea when the Gremyashchiy will be commissioned? It was launched around the same time as the Gromkiy. I wonder why it takes so long for the Russian Navy to commission ships.
    It hasn't started sea trials quite yet & all-new Zaslon system will have to be extensively tested even if its all actually working. (worst case see Gorshkov)

    What about Retivy and Strogy in STP  they were planed for 2018? Any info about them?
    They are almost certainly getting the same Zaslon mast as Gremy so like Kasatonov was held back by Gorshkov, these two will probably not proceed to trials before Gremys Zaslon is shown to be working properly.

    Rear Admiral Igor Korolev said that “two more corvettes of the project 20380 will be built by the Amur Shipbuilding Plant. They are basically the same project, but they have one feature. If we look at the tower-mast complex, their U-shaped mast will disappear, and the front one will acquire several other outlines, and a multi-functional radar system of the ship will be installed in it. "
    This is describing the same mast config as Gremy so is probably also confirmation that Retivy and Strogy are getting the Zaslon setup & also that these two will only progress after Gremy.

    Of course doesn't rule out launching of hulls which would probably be a good thing.

    Fine but still the range of Zaslon is 300 km, source:

    Hmm, they previously said 75km for 1m^2 target which always sounded kinda weak to me. But its definitely not Poliment.

    AFAIK 20380 use  Furke 2 for aerial targets. Wiki says about Furke 2 detection:

    120km          1m2                   observation mode
    .72km in       1m2                   battle mode


    Anyway Radar horiozn with its mast height is not that large and AAM have much shorter range.

    Edit: verkhoturye51 provided link to - Jane's: Info there is about Zaslon indeed. But this on if fresh: 20117) and for 20385.

    I'm talking about Zaslon, the 75km 1m^2 range is 2:09 in that video.

    Well range of poliment on 20385 is not really bigger right? BTW I'm not a radio engineer but what is difference in passive mode there? L band is in passive mode means can see stealth objects

    Passive L band means it can detect a radar emmiting in L bands (ships, awacs and ground based syrveillance radars mostly). Passive means it only "listen" to signals send by other radars. It's radar warning receiver if you want.

    Stealth fighters radars don't work in L band. If you want to to see them you need active L band radar.

    So this source confirms Gremyashchy has Zaslon M and ranges are 300 km generally and 75 km for 1 m2. Still I don't think many Russian ships have much better aereal target radars except for Gorshkov and the three heavy cruisers/CVs (and Grigorovichs by tiny margin).

    20385 has Zaslon not Poliment.
    I don't think I've seen any quotes on the detection range of Poliment but I assume its more powerful.

    poliment redut missiles I meant ;-)

    Poliment is the radar on 22350, redut is the VLS cell.
    Consistent naming 20380 have Furke-redut & 20385 would be Zaslon-redut.

    Would probably be better if they gave it a unified name like Naval Vityaz or something.

    probably they want to confuse US intel lol1 lol1 lol1

    BTW Russians stopped building 20385 due to price? then why didnt use 22160 hulls Idk. Good buoyancy, half cheaper then 20380 and ~30% of 20386 price + range 6,000 nmi.
    OK range could shrink, and price go up but good hull and still cost savings.

    In this case "nomen non est omen", meaning that name is not the essence.

    Well the missiles are active radar homing missiles so they don't need a specific radar. Any radar precise enough to bring them near the target with the good data link implemented inside will work. Weaker radars will be used with the 40km range missile while bigger and more powerfull one will be used for 150km range missiles.


    That's why they can use it on so many ships. Very good system that gives pretty good anti air capabilities to any ship.

    Apparently Gremy is to start sea trials soon https://flot.com/2019/%D0%A1%D0%B5%D0%B2%D0%B5%D1%80%D0%BD%D0%B0%D1%8F%D0%92%D0%B5%D1%80%D1%84%D1%8C3/

    Has been a surprisingly long time since it was seen doing de-perming, was a rumor at Balancer that they discovered a gearbox issue.

    Well, this time of year is called winter and to my knowledge this season can be pretty hard in Russia. Maybe they just wanted to wait until the conditions are more favourable.

    I mean it was (presumably) a Russian (presumably) in Russia asking 'its been a while since the de-perming pics, when is it going to sea?' in Russian on a Russian site known to have insiders and the answer was 'I heard they found a gearbox fault'  dunno
    More recently ppl saying 'its fixed' and now this article saying sea trials soon.

    Stealth fighters radars don't work in L band. If you want to to see them you need active L band radar.

    L band signals are used for the datalink between western aircraft ie NATO link 12 etc, and also to send commands to AMRAAM missiles.

    The L band AESA in Su-35 and Su-57 is active and passive but can operate 24/7 in listening mode to detect communication and long range missile launches with AMRAAM... and actively scan when needed to.
