    No the 3rd Amur 20380 was visible in the background when they were doing the 22800 laying down ceremony.

    Gremy has apparently passed first factory tests, planning to transition to Pacific via Northern route in Sept, finish tests there.
    Implies that they're not expecting to need to do big reworks eg on the radar system, which is a good sign.

    https://ria.ru/20190628/1555996850.html
    “The newest corvette of the project 20385“ Gremyashchy, ”which has now completed the first stage of factory testing at the Severnaya Verf plant in St. Petersburg, will make the transition by the Northern Sea Route to the Pacific Fleet in September to conduct the final part of the state tests,” Voskresensky said.
    It is planned that the Pacific Fleet, in cooperation with representatives of industry, will test ship weapons, including launches of Caliber missile cruise missiles.

    I'm pretty sure that that North Sea voyage will double as second phase of trials

    How many corvettes travel from St.Petersburg to Vladivostok via Arctic? Cool

    They appear to be testing radio-transparent paints?

    The next 2 ships will apparently feature a new "3 eyed" radar to replace the current rotating radar...

    sorry only a rough machine translation...
    Corvettes of project 20380 Steregushchy will be equipped with innovative "three-eyed" radar, which together with long-range air defense system "Redoubt" make the ship virtually invulnerable to air attacks, write "Izvestia".

    It is reported that three aerial paintings will replace the rotating antenna unit, which is now installed on the mast of a ship. That is because of the appearance of radar and dubbed the "three-eyed". The main advantage of the new radar is the fact that they are more "long-range" compared to currently.

    The new radar would enable air defense systems to reflect a stronger attack cruise missiles, most of the way flying to the target at low altitude. In addition, they better find drones, able to get lost in the radar "noise", represents the interference created by the enemy or the atmosphere.

    A source in the Navy Command reported that in the experiment, the radar is stationary with three paintings installed on the two corvettes of the project 20380 "Sharp" and "Aldar tsydenzhapov", now under construction for the Pacific fleet. In case of successful passing the test radars will begin to be equipped with all the ships in this series....

    Nice.

    With AESA radar using electronic beam scanning it would be much better able to track and find targets compared with a rotating dish... remember at sea the antenna wont be kept perfectly level and stable all the time so electronic scanning with stabilised beams means more precise tracking and if something needs to be scanned again it can be because there is no mechanism turning the antenna that has to be stopped and turned back to scan a direction...

    The other factor is that production of these radars means production of AESA elements... the more they are produced the cheaper they will get and the more refined the production process will become so that dud rate will be reduced and production rates increased...

    Hmm, could that be a mistranslation of 3-frequency?
    20385 has the big passive at the bottom, AESA middle then something that may or not be Furke at top.

    If they're introducing a 3rd all new system that'd be madness.

    "... the radar is stationary with three paintings…"

    For me this sounds like the radar of Gremy.

    I believe they spoke about unifying more components between the 20381 and 20385

    My understanding of the description is that they are replacing a rotating conventional antenna with three fixed phased array radar antenna, presumably each able to cover 120 degrees, meaning three antenna cover the full 360 degrees without needing to move... meaning electronic scanning rather than physically moving antenna for scans...

    So there has been a 3-panel radar in development & I think thats appropriate timing relative to when these ships were laid down dunno

    in a sense it is also stealthier in that there is no spinning antenna, but the critical thing is being able to see 360 degrees all the time without needing to move... because the radar elements are pointing in all directions it means it can electronically scan in any direction or even all directions if it wants to but the sensors remain fixed so any returns can be detected... there is no chance of a radar signal arriving when the radar is turned in another direction, so scanning and listening for radar returns is much more effective and efficient... indeed when operating with other platforms... say an AWACS aircraft... when it is scanning your ships radar can be turned on but not sending out radar emissions... you can be listening for returns from signals from other platforms... a radar beam coming from otherwise empty space is interesting... it might have come from an AWACS platform 200km away hit a B-2 stealthy bomber but been redirected away from the AWACS platform but your ship picked up the signal because it happened to be in the path of the redirection... normally such a thing would be useless, but with a battle management system in a data network where ships and subs and aircraft and satellites share information, that AWACS would have a record of the time and direction it sent that signal and together with the receiving information from the ship should be able to triangulate that signal so with further scans and listening it should be able to track any stealth target even in the frequencies the stealth aircraft is supposed to be hard to track using... certainly enough to send a missile to the targets vicinity where an IIR missile should be able to get a lock and a kill...

    Initially those AESA will be expensive but as they are built in large numbers and more widely deployed the costs per element will come down and the size and weight will go down too... not to mention software engineers will enable more and more features... the production dud rates will go down, as will the production price and production volume will increase as well...

    Yeah, that was touted around as possible concept for 22350M but I think everyone settled on it as just a promo pic to represent rough size/locations the different antennae could be used.

    Likewise the one with the 3-side radar on a 20380 was taken as just a promo indicator of possible use.
    But if they're actually using this 3-sided array on a 20380 maybe the other one is actually an indicator of 22350M Suspect

    Gremy started state tests

    If the Barrier/Zaslon radar stuff isn't working properly I wonder at what point it'll show up?
