    I really want to see more detail of that Kamaz reloading truck.

    T-90 chassis? I thought the T-90 was on a T-72 chassis? May'be there'll be a technology demonstrator version for arms trade shows where the top half will be the Coalition that you would find on a Armata chassis, and the bottom half will be on a T-72 chassis until the Armata chassis is ready for display. May'be the Coalition on a T-72 chassis will be an export model for poorer countries.

    There was a video some time ago, it's either in the news thread or the video thread here. Anyways, it highlighted some new equipment, one of which was Coalition's completed turret.

    We know for a fact there's at least one functioning Coalition turret, yet we don't know how far along the Armata chassis is. IIRC, there's supposed to be three Armata's which were built for testing. Since Coalition is digital, any chassis could be used for testing and the turret could be controlled using a laptop outside the vehicle. With a limited amount of Armata's available, it doesn't make sense to waste them when a T-90 chassis could do the same for the testing phase.

    It's likely that at least one of the completed Armatas will have to undergo endurance testing, so that only leaves two hulls for the developers of the subsystems to play around with.

    T-90 hull is a close T-72 offshoot, but the chassis has many differences. Even in dimensions.

    I agree with Zivo... they might test the turret on a T-90 chassis but the Koalition turret is unmanned so operationally it would need an Armata chassis or a custom designed wheeled platform that has room for the entire crew outside the turret to operate the vehicle.

    For export the wheeled version would probably be much cheaper and more mobile on roads, which would probably make it more popular for export.

    How are they gonna fit this hulk of a turret onto the Kurganets-25 that's my question.
    Will be top-heavy as fk.

    And for the wheeled brigades? I'm guessing no unified chassis so they're going to use the Kamaz-mounted version of it.

    Perhaps with a Kurganets model they might mount the gun externally on the rear like the 2S9 and 2S5?

    Or perhaps the wheeled models are for the two medium brigade types and the light brigade will make do with 120mm gun/mortars.

    It would also be possible that the tube and rocket artillery are taken out of the brigade structure and added or removed when needed as separate units when required... a bit like an old machine gun platoon.

    Remember the wheeled units will likely form the same basis (ie chassis, engine, gears, transmission, etc) with a new truck family too and that truck family could be used with those wheeled brigades without adding too much to the brigades logistic tail.

    Maybe they could modify the turret like the archer turret. Remove a lot of the extra magazines in the bustle, reduce the turret ring to a minimum etc.
    Edit: tho the hull has been discussed before- imo this is the best design for armata chassis. The front looks very Abrams-ish
    tho its still massively thicker and protrudes into a nice vertical slab more like turret armor.
    Also I see thick track sponsons- possibly precluding use of composite armor there too. It doesnt look like it covers the lower part of the
    hull but if you think about it the crew are sitting on reclining chairs that would prolly be raised along with the hull floor too for mine protection.

    The design is very close to Object 195. The lineage is apparent.

    Keep in  mind that the MBT, BMPT, etc. will also have add on armor kits. ERA on the front and sides, heavier skirts, the works.

    Lots of great news.

    Russia’s state-of-the-art heavy armaments (the Armata tank platform and the Koalitsiya (Coalition) self-propelled artillery system) will be presented to the public for the first time at the Victory Day Parade in Moscow on May 9, 2015


    Work to build first batches of promising heavy combat platforms are proceeding ahead of schedule

    Siyenko said all characteristics of new systems outlined in the Russian Defense Ministry’s requirement specification have been confirmed during tests

    The tank will have a remote-controlled gun (unmanned turret) with all-digital control, and the crew will operate it from an isolated armored capsule.
    The self-propelled artillery system 2S35 Koalitsiya-SV (Coalition) has two 152-mm barrels; the export modification will have a 155-mm caliber barrel

    twin barrels is awesome- you halve the vehicles needed for a barrage or you deliver twice the fun in a barrage.

    The information I remember reading suggested they reduced the number of guns to one to make the turret slightly smaller so it would fit on air transport.

    Both guns in official line drawings had twin belt feed ammo supplies... presumably to allow different types of ammo to be fired at the flick of a switch.

    Note the Koalition turret is unmanned too.

    The dual feed picture is from the naval version which was developed together with the army version to reduce development costs... an excellent development on its own.

    I knew some forums had rejected it, but I never saw anything to the effect that they had.

    The fact that MSTA is a good gun already is likely a part of the problem, but joint development with the Navy suggests lots of investment and likely new technology went into these vehicles... I doubt they would cancel it outright unless it was a real dog.

    Any news on the chassis use for Koalition?

    Won't Koalition be on a unified platforms? I thought it isn't a question. Koalition is actually a weapon module, we've only partly involved in one of the chassis design (electrical part of the chassis design).
    Personally, I can't say is it reasonable to put Koatilition on, say, expensive Armata chassis. It is known one of the Koalition variant (for future light and/or medium brigades most likely) will be on Kamaz chassis, for example:

    2S35 Koalitsiya-SV 152mm - Page 4 Koalitsiya-sv_kamaz-6560.t
    KAMAZ now is 'unified' platform too as it seems all army trucks tends to be KAMAZ now. There can be cheaper 'Armata' chassis for numerous engineering vehicles, for example, which could be  used for artillery chassis as well.

    Yes of course, but so far the glimpses of Koalition have seemed to indicate a modified T-90 chassis.
    Was wondering if there is any movement towards the new chassis being delivered to Burevestnik for modification.


    i think the KAMAZ chassis is a terrible idea personally.

    a modified T-90 chassis.

    That would broke the idea of unified platforms, imho.


    Was wondering if there is any movement towards the new chassis being delivered to Burevestnik for modification.

    What do you mean? I think made it many times during design process, but we are not envolved in it, as we are side contractors working on initial data given.


    i think the KAMAZ chassis is a terrible idea personally.

    Test will show (or have arleady shown). Kamaz chassis have some benefits, e.g. weight, cost, repairability. It's like a towed gun, which shouldn't be dismounted before firing (reducing preparing time). 'Light' units always did have towed artillery (for example, many BTR-counted motor rifle divisions usually had several battalions of towed 122 mm and 152 mm howizers)
