    Ok thanks. That is strange because the Granit is not that much bigger in terms of diameter compared to the Onyx (0.85 vs. 0.7 m)


    The cell size is fixed and as you can see in the picture above the use of 9M96 missiles does not fill the cell efficiently. Having a quad liner for the cell so four missiles could be loaded makes sense but if the missiles are shorter as well as narrower then why not have layers too?
    Yes that is the idea.
    One tube could carry one S-400 full sized missile with a range of 400km, or it could carry a normal S-400 with a 250km range, or it could carry two layers of missiles with four missiles packed into each layer for 8 x 9M96 missiles per tube, or three layers of 5 missiles with the 9M100 missiles with a total of 15 missiles per tube.
    ...
    It would make bigger ships very formidably armed...
    I referred to smaller ships because they already have no huge amount of the big CMs /ASMs and therefore further reduction by using up some cells for SAM would maybe not be as interesting as spreading the SAM cells in swallower areas of the ship. In bigger ships you would be better off by stacking and putting short/mid range SAMs side by side in deeper cells, it may help using up the hull better.
    I don't see the point in unification of the UKSK cruise missile launchers and the Redut SAM launchers... the difference between the small SAMs and the big SAMs is big enough already without adding enormous cruise missiles to the problem.
    S-400 tubes and VLS are not really different in size. Some missions may need more offensive firepower, other more SAMs. Flexibility is always good, as well as unification. Don't have a strong opinion on feasibility though.

    You could have small shallow 9M100 launchers all over the place as they are short range lock on after launch IIR guided missiles that would always be useful... even embedded in the sides of ships facing outwards...
    Agree to some point, but complex technical setups are cheaper and easier to maintain if concentrated in one or few areas. Our technology is not that sophisticated yet to have missiles on a ship as if they were leafs growing by themselves on a tree if you know what I mean

    Could make sense as said above. Even when smaller VLS cells will still be needed.

    The information released stated the Granit launch tubes were to be kept and fitted with launch tube liners and the payload was going from 24 Granits to 72 Onyx missiles...

    Will always need a crane to lower the weapons into the launchers, but a better design would be to open the hatches and lower complete tube liners containing the missiles all ready to fire into each cell.

    Side mounted cells would be tricky to access, but just a use of available space...

    Source: Polymer-Redut air defense system will be put into service in the first half of 2019

    The interlocutor of the agency noted that all tests of the anti-aircraft missile system are scheduled for completion at the end of 2018

    At the end of 2018, it is planned to complete all tests of the air defense system from the Corvette Project 20380, including firing from this carrier to air and sea targets. In the first half of 2019, the complex is planned to be used by the Navy," the agency’s source said.

    The source said that the “Polymen-Redut” air defense system will be armed with all new and upgraded surface combat ships of the corvette and frigate classes. "The air defense system will also be installed on the Admiral Kuznetsov aircraft carrier and on the Admiral Nakhimov and Peter the Great heavy nuclear missile cruisers during their renovation with modernization," the source added.

    Earlier, tests of the complex were successfully completed on the main frigate of the project 22350 "Admiral Gorshkov". According to open sources, a version of the Redut air defense system is currently being installed on the corvettes of the project 20380, without the Polyment radar antenna with a phased antenna array.

    "Polyment-Redut" - a shipborne anti-aircraft missile system with a vertical launch. According to open sources, the system is able to use 9M96MD anti-aircraft missiles with a maximum range of destruction of air targets up to 150 km.

    It is interesting... sometimes they say 40km and 120km range for the big and small 9M96 missiles and sometimes it is 60km and 150km range... perhaps the two shorter ranges are for the export models?

    BTW had a look at photos of the Granit launchers on the Oscars and the tubes look to be over 1m across... perhaps the rear fins don't fold?

    The tubes on the Kuznetsov are big too.

    The range of 40 and 120km was mentioned back in the late 90´s as the 9M96 emerged. Engines and propellant got better since then.
