    The 20836 is first and foremost a technology demonstrator and testbed for emerging new construction technologies.  It is as radically different from previous corvettes like the 20830 Steregushy as the 20830 was from the 1135 Burevestnik/Krivak.

    What, do people really not understand this????   Seriously????   Suspect

    FFS its just a single hull being developed as a first-of-class for a post-20830/20835 corvettes.  Just sit and watch and see where it goes from here.  The Russian navy isn't going to make-or-break on one 3,400T hull....

    Sure, but if you look at the specifications that are available, it is supposed to use similar propulsion to the Admiral Gorshkov in number of and type of turbines. It is getting close to the displacement of the Admiral Gorshkov. Yet it has like a third of the VLS cells. Once Admiral Gorshkov gets updated i.e. Admiral Chichagov this 20386 will look even more anemic. And I also doubt it will have the same seamanship capabilities. I mean just look at it. Wtf is it with a "corvette" with 3400 tons displacement? Ridiculous.

    Well part of the problem is that the navy has changed.

    Corvettes used to be single design ships for one mission only... often that mission was anti ship/anti carrier with large heavy anti ship missiles like the OSA with a medium gun that was normally used during peace time as a patrol boat... the enormous powerful missiles silly and redundant most of the time.

    Skip forward to now and their new corvette designs can still have anti ship missiles, but even Uran armed ones can use their missiles against land based targets, and most are fully multirole with UKSK systems enabling a range of weapon loads... not to mention massively upgraded sensors and communications equipment... they are fitted with Sigma, which is the Russian equivalent of AEGIS.

    More importantly the Russian Navy really did not use a lot of Frigates... most of there Frigates were used by the MVD and KGB as coastal patrol and light duties, the Soviet Navy tended to use destroyers for near and far operations... they didn't travel enormous distances a lot with them either.

    It seems the sophisticated nature of their new Corvettes and Frigates means these two types alone could probably handle most local defensive operations around Russia, but the new helicopter landing ships and the Ivan Gren type landing ships that will be replacing older models will need support ships like destroyers and cruisers, and of course aircraft carriers for operations great distances from Russian waters.

    They need different corvette types because corvettes are the smallest ships so it is harder to make them fully multirole.

    No ship would normally act on its own and ships the size of corvettes and frigates are designed to defend themselves but are not big enough to protect other ships.

    An anti sub mission one corvette would be useless, but combine 3-4 corvettes and add a few frigates and you end up with a capable well armed force with quite a few helicopters and drones capable of hunting down enemy subs.

    Having different types of corvette makes sense, but a frigate sized ship should be big enough to have sonar and radar and a variety of weapons to protect itself.

    A destroyer is even bigger and can be even better armed to not just protect itself but also other ships, while the whole purpose of a Cruiser is size and weapon capacity and sensor size to protect a group of ships, while a fixed wing aircraft carrier is there to provide eyes and ears and a 360 degree view of the sea and air around those ships so nothing can sneak up and surprise them.

    Carriers don't make groups of ships invincible... but they make them much more costly to attack and will defeat attacking forces that would have beaten the same group of ships without that carrier and its air component.

    The presence of a carrier in the Falklands war made the British Force viable, though it was a close run thing because pocket carriers with useless VSTOL fighters were marginal in the role at best. If they had had a better carrier with Phantom fighters with Sky Flash BVR missiles and Buccaneer strike aircraft and of course AWACS aircraft they probably would not have lost ships and would not have needed the risky Vulcan missions.

    Russia has five fleets and extreme climatic conditions... having one or two extra different corvettes is a good idea just to see what works best and that means if they work as planned they can buy the correct number of ships and place them where they are most useful.

    indeed the not all Navy ships are missile platforms, some ships have other jobs and roles that do not require that.

    People on this forum have such a one-dimensional view about the Navy it's sad.

    Very much agree... the measure of a ship is not how many missile tubes it carries... impressive as that might be.

    The Mercury is a larger version of the Bykov class. Made for long range operations with changing modules of weapons/sensors/drones/UGVs and so on. The guns and missiles build into the hull are just the tip of the iceberg.

    Some strange writing to be honest. They make it sound like they can build the gearbox and engines one or the other. Not saying anything that they can or cannot increase production.

    But I think some on authorities are not interested in this ship

    Some strange writing to be honest.  They make it sound like they can build the gearbox and engines one or the other.  Not saying anything that they can or cannot increase production.

    But I think some on authorities are not interested in this ship

    This article is shit.  Thats not an off-the-cuff comment.  Its a considered viewpoint and one that I've settled upon after much thought and due consideration. I could be more verbose in my pronouncements (like in this paragraph..) but I feel that succintness is the best approach in this case.

    Hilarious that the author choses to quote other gibberish to apparently suggest that the concept of distributed lethality is somehow a failure. Consider the following:

    The main thing that does not suit us is the too high price and excessive armament - the Kalibr cruise missiles, which work against sea and ground targets. Project 20385 does not meet the requirements fleet", - said the interlocutor of the publication. According to him, the estimated cost of one ship is about 14 billion rubles, but in reality it can reach 18 billion. For a corvette with a displacement of 2,2 thousand tons, although made using stealth technology, this is a lot. The equally modern frigates of Project 11356, which are now being built for the Black Sea Fleet, have a displacement of almost twice as much - 4 thousand tons, and cost the same.

    The frigates of this project are ships of the open sea, with a significant range, and the corvettes 20385 are intended for the near sea zone. Sailors believe that such a powerful weaponlike "Caliber" to these small ships unnecessarily.

    Really? The 11356 is equally modern as the 20385, despite that fact that the 11356 isn't much more than a tarted up Talwar-class with a UKSK system?

    If "sailors" think the 20386 doesn't "need" a UKSK system, what does that say about the 21631 Buyan-M?  I guess because the guy who peels the potatoes or changes the bedclothes doesn't see why corvettees should be able to sink an enemy destroyer with a supersonic AShM, we should just remove the offending ordance and fit something more "suitable" like a few 75mm guns and a few RBU launchers???  Suspect

    The rest of this shoddy article is just the author puking what seems to be his personal disapproval of the concept of modularised systems, and his pissing and moaning about what he sees as unacceptale compromises.

    He yabbers that the 20386 artillery system will be "less effective than that of the old 20380" yet they both have a single A-190 gun.  Suspect

    He complains that the hanger location will require a lift which is "an expensive and technically complex solution" - really? He think a hydraulic lift is complex?? Suspect

    He complains that specialist containers can't have overboard access to the sea without moving the FRC - yeah, so fucking what???  Suspect

    He complains that if a large 40" container is carried, the helo will be displaced from the hangar. Yeah, again so what?  Thats the whole fucking idea about modularity.  The ships configuration can be adjusted to match the fucking needs of the mission.  If the helo needs to sit on the back of the deck under a tarpauin and only be used when necessary (ie if other ships in the taskforce can't meet a specific operational need) so what?  Its a 3,400T hull, not a cruiser.  There isn't room for everything at once. The idea is to be able to reconfigure to maximise specific capabilities, and that requires a downgrade in others deemed less important to the mission.  Suspect

    Check out this utter bullshit...  /facepalm x 100

    A special problem is the placement of the antenna sheets of the radar complex on the sides of the superstructure, which is made of composite materials.

    Many experts believe that due to the inevitable deformations of the superstructure when moving in waves, the canvases will “play”, randomly changing their position, which will make accurate shooting impossible.

    Wut?  This idiot thinks a flat panel array is supported by the outer skin rather than the inner structure? Does he really think the panels will move due to weather effects or vessel motions?  Does he really think that Russian naval architechs are so unutterably stupid that they don't know how to mount ships systems to a vessel that uses composities in its construction???    Experts?  What "experts" are saying this crappola?? Suspect  

    Then we have this little pearl of Sun Tzu-level wisdom:

    But even if everything works, nothing will work anyway.

    Yeah, I know I'm reading a translation, but even the dumbest literal machine couldn't disguise the empty-headed know-nuffin qualities on display here as he proceeds to lamblast the vessel radar system on no other facts than their location on the superstructure and unsubstaniated "wisdom" from the US and ChiComs.  Gods above, i need to marshall my strength to keep reading this nonsensical shit-slurry...

    I lost my will to continue as I fought my bodies basic need to expel stomach contents as I read his amateurish and arbitary "critique" on the 20386 powertrain configuration.

    Nah, this scribbler-for-hire just doesn't get it, and he is clearly working with an agenda.  The question is who is putting bread is his begging bowl and calling his tune?

    He's not a Ukrainian by any chance?  Suspect

    We shall see what the end results will be. This does scream the typical "know it all but hasn't accomplished anything experts".

    It has strange writing because this website seems to be compete dogshit (been saying this for a while)

    Not only do articles seem to be machine translated but so are the comments, first time I'm seeing it

    That's on top of the fact that what they write is mostly crap
