    2S35 Koalitsiya-SV 152mm - Page 5 Empty Any news on the chassis use for Koalition?

    Indeed Trucks move much faster on modern roads and are cheaper to operate and simpler to maintain than tracked vehicles.

    I suspect the turret is a modular system that can be dropped into any suitable vehicle chassis or trailer.

    the Naval version will have under deck ammo handling and likely two barrels, but otherwise should be similar.

    The thing that probably stands out for me is the back portion of the hull.

    That's not accurate, the Koalition SPG is a joint project between the Russian Army and Navy. To say their won't be a twin barrel version is not actually true because a twin-barrel version will exist for the Ru Navy, it's actually more accurate to say their won't be a twin-barrel ground forces version.

    They're won't be a ground forces version of the twin-barrel Koalition, at least initially...according to what the so-called 'reports' (only time will tell how credible they are)  have said, but assuming the 'reports' are true, it's not entirely impossible that the first versions that will be delivered will be 'one' barreled, but later versions that are delivered post-2020 that are twin-barreled could be delivered if the Ru-Army finds the extra weight and complexity being out-weighed by it's usefulness. If a single barrel version is capable of landing 6-10 shells on simultaneous impact, with GLONASS-kits and with additional laser correction being emitted by UAV's, than twin-barrel versions may very well be able to do the same with 12-20 shells. If the twin-barrel Koaltion proves that it can guide 20 shells on simultaneous impact, than it can prove than it could diminish the need (by a reasonable extent) for the use of additional bunker buster bombs, because in all-likeliness firing 20 shells at a target will probably be cheaper than having a Su-34 doing the same job with 1 or 2 bunker-buster bombs. Additional glide-kits created for Koalition shells may extend the range beyond 70 km, and in to the 80, 90, or perhaps the 100 km range.

    Then I see no point in buying single-barrel version at all. Why not to produce twin-barrel version from the beginning?

    Twin barrel version with twin belt autoloader was too big to fit in transport aircraft and in 2020 will likely still be too big.

    Size does not matter for the naval version of course because even the smallest destroyer wont fit in a transport aircraft...

    Having 6-8 shells land on target at one time means a battery of 8 vehicles can deliver 8 x 8 = 64 shells all at once to the target, which is 2.7 tons of steel and HE landing as one on the target... I think the target wont even feel a thing.

    It will be nice if the two barrel version could each one be configured to hit not in the same place..
    with about ~20 meter distance if they desire , that will significantly allow the artillery to cover wider area about twice of it in about same time. But if both barrels hit nearly the same place it will be wasted ammo.. in the case it hits nothing or that is over kill for the target is seeking to destroy. A modern tank can be disabled with just one hit.

    Why would it be a waste of ammo? Hardened bunkers are designed to withstand a hellish onslaught of damage, on the high end some bunkers (such as strategically hardened bunkers carrying ICBM's such as the SS-18) are designed to withstand 6000 PSi with ease, if the twi-barrel Koalition is capable of 20 shell simultaneous impact than a group of 10 twin-barreled Koalitons carrying 60 rounds each with a newer generation of bunker-piercing shells with GLONASS and glide-kits (with additional UAV laser correction), could make a mockery of tactical bunkers created by a fairly advanced insurgency (lets say it's sponsored by Ukraine or Georgia) that are hardened to 60 PSI. Plus the need and the worry for Koalition to guide shells 20 meters away is rather meaningless considering with GLONASS-kits, glide-kits, UAV laser correction could easily do that and not to mention a new generation HE-Frag munitions could (if not now already) make 20 meters well within it's 'lethal' radius against personnel, and the worry is baseless any way considering they'll be 'multiple' Koalitions in a unit capable of firing on different targets.

    Garry what makes you think a single-barrel Koalition would be only to able squeeze a measly 6 (or 8 for that matter) shells for simultaneous impact? I know I mentioned 6 shells in a earlier post (I apologize that I misspoke), but let's think about this now, the Pzh 2000 is capable of 5 shell simultaneous impact with the unreliable human element loading the powder charges separately, and the Pzh 2000 had it's design roots from the mid-1980's, and it's finalized design ready by the the mid-1990's using older and less-efficient computers. Russia is a country with hands-down the most experience creating auto-loaders, so creating a fully automated loading system (eliminating the unreliable human element) for the single-barrel Koaliton, as well as newer, more powerful and efficient digital computers should 'easily' land 10 shells per target. For it's limit to be only 6 shells would be a big let-down if not a clear sign of under-achievement, and if there is a human operator loading powder charges separately, than it would defeat the purpose of the Armata chassis ( created to have a separate armored capsule designed to keep human operators away from highly-combustible ammo). A human operator loading powder charges separately would leave them outside the armored capsule (and the vehicle for that matter) and within close proximity of the thinly armored ammo storage area.

    It will be nice if the two barrel version could each one be configured to hit not in the same place..

    The shells are guided... and there is no reason to even fire both barrels if the target doesn't require it.

    The two guns are there to increase the rate of fire, not to get two shells on target.


    with about ~20 meter distance if they desire , that will significantly allow the artillery to cover wider area about twice of it in about same time.

    If you want area coverage then use Smerch. The Koalition is for area targets and point targets. For area targets non guided shells could be used.

    But if both barrels hit nearly the same place it will be wasted ammo.. in the case it hits nothing or that is over kill for the target is seeking to destroy.

    Two shells hitting a building or bunker or wall will not be twice as effective but will be an improvement with regard to effect.

    A modern tank can be disabled with just one hit.

    probably true but two guided shells coming in at nearly the same time might improve the chances of penetrating APS system defences for example.

    If the target is a line of trenches then delayed fuses with the shells burying themselves in the ground near the trench before exploding would be devastating to the trench line... two shells even more so.

    Garry what makes you think a single-barrel Koalition would be only to able squeeze a measly 6 (or 8 for that matter) shells for simultaneous impact?

    Not many targets would justify more shells. An enemy unit caught in the open, 8 shells all using GLONASS guidance to space their detonation points with airbursts at say... 3 metres above the ground and a very large area becomes a killing ground.

    Just looking at video footage from Afghanistan with the British forces there and it is all open and exposed with very few places to hide or dig in... even just 4 x 40kg HE Frag shells would be devastating.

    A human operator loading powder charges separately would leave them outside the armored capsule (and the vehicle for that matter) and within close proximity of the thinly armored ammo storage area.

    There are no human charge loaders. The mechanism is fully automatic with a belt feed from each side loading shells and propellent charges.

    I agree, based on your premises that a higher rate of fire would be likely, but then an F-16 can carry a max payload of 7 tons. It is a question of need.

    I very much doubt a battery of Koalition vehicles would need to fire 20 rounds... the vast majority of the time it will be a few rounds to hit a few specific targets.

    Obviously when the targets location is not know exactly a salvo of dumb unguided shells might make a 20 round volley useful, but in such circumstances I think rocket artillery would be more effective.
