    If it did not have that extra propellent then you could give it a rear turret bustle that just carried APFSDS penetrators. That would mean even if penetrated then it would be no risk of fire to the crew and you could put as many long rod penetrators in there as you liked.

    The main threat to the crew of ammo being hit is when HE rounds explode... which detonates everything at once with obvious lethal results for the crew.

    Having APFSDS rounds in the turret bustle exposed to enemy fire but separated from the crew by an automated loading system that only opens when passing rounds in to the gun would minimise the risk to the crew... allow rather more ready to fire rounds of ammo with much longer penetrators to be carried.

    Blow out panels in the roof could be used to redirect any propellent fire away from the crew compartment and other ammo....

    You could actually do it the AMX-140 way. Crew doesn't touch the ammo at all unless you reload rack. Direct armored funnel from bustle to breech.

    That's just a design constraint. With the new semi-oscillating turret on the T-95 that I hope integrated in the T14, the rounds will be whole. But even with the current space if they manage to move most electronics out of the ring, then there would be more space. How much more space...that's another question.

    Also Object 640 did the exact same thing. Stretched Hull, plus rack. So if the Rack was proven a liability on the battlefield, you could go back to a traditional autoloader and have space for longer rounds.

    So, i came across this video today (from mid 2016) of a T-90 that has supposedly taken a few hits somewhere in Syria.
    Forget about the second half of the video.



    I was wondering if the damage seen in the video has been created by RPGs or other HEAT type rockets, or if it is from some large calibre gun.
    I know that the gaping hole in wheel at the start of the video seems akin to the damage caused by a rocket but the damage to the Shtora dazzlers seems more like it's just been shot up with a gun.

    In any event, looks like it's taken a beating and is still soldiering on. good on it.

    Roadwheel shot is RPG/SPG, Hit on Shtora I sdifficult to asses, looks like 12.7. But TIS has been blown away. Pretty much gone head on in a strong point. The rest looks like a lot of small calibble and schrapnel.

    Russia's T-90 makes inroads in Middle East market
    Jeremy Binnie, London - IHS Jane's Defence Weekly

    http://www.janes.com/article/72090/russia-s-t-90-makes-inroads-in-middle-east-market

    An annual report released by Russian tank manufacturer UralVagonZavod (UVZ) revealed a series of T-90 deals with Middle East countries.

    The report was published on the UVZ website, but later removed after Russian defence analysts revealed the customers it identified using code numbers.

    According to these analysts, the report stated that UVZ is planning to implement orders that Iraq and Vietnam have placed respectively for 73 and 64 T-90S/SK tanks, to finalise Kuwait's order for 146 T-90MS/MSK tanks, and work to secure an Indian order for 356 T-90MS tanks.

    The T-90S is the basic export model, the T-90MS (also known as the T-90SM) is a more advanced export version, and the 'K' postfix is a reference to command versions.

    UVZ will also work on a project to establish a facility to license assemble T-90S/SKs in Egypt and another to establish repair facilities for the T-90S/SKs already delivered to Algeria.


    The T-90 has previously struggled to find customers in the Middle East, although Russia has supplied a small number to the Syria Arab Army or allied pro-government militia.

    So Russian Army will receive T-90M.

    AFAIK its a modernized of T-90A.

    http://bmpd.livejournal.com/2808456.html

    Anyone can find more info on contract? Number of tanks, modernization of old T-90As or new built T-90M?

    Supplies of modernized T-90M tank to military may begin in 2018

    The supplies were contracted at the Army-2017 military show, the producer told TASS

    NIZHNY TAGIL, September 9. /TASS/. Supplies of modernized T-90M tank to the Russian military may begin in 2018, head of the producing plant, Uralvagonzavod, Alexander Potapov told TASS on Saturday.

    The supplies were contracted at the Army-2017 military show. The plant’s representative refused to quote the number of tanks to be supplied.

    "We are not disclosing numbers, but we have signed a contract on supplies with the Defense Ministry," he said.

    While speaking about possible export of the Terminator AFV (armored fighting vehicle), he said the plant is "open for a dialogue," though added this issue is responsibility of the Federal Council for Military-Technical Cooperation and of the Rosoboronexport defense-export authority. "Of course, we are interested in sales of our products, including AFVs," he said.

    Clearly, the image on the poster is NOT the vehicle being displayed. Is the designation T-90M correct?

    They probably got the picture wrong, this development seems to be continually evolving. There are many differences between the photo and the tank standing next to it. Earlier T-90M prototype photos had a slat not curtain defence.

    Everybody says check pci below Smile As for T-90M what worries me it does not seem to so much be Proryv 3 with Armata gun ( 2A82-1M) but instead old 2A46M4?

    I think the upgraded T-90M (or lets say AM) won't have new gun. Only new built T-90M will get the Armata gun with fume extractor added.

    Another thing to note is that the RWS this time seems to be equipped with 12.7mm Kord rather than 7.62x54 PKT.

    Well Kord is new standard so this is just keeping up with times.

    Not really. It doesn't need to stop it, it just needs to change RPG trajectory angle.

    This is why Armata APS will be able to deal with sabot rounds. Everyone thinks it is just advertising because sabot can't be stopped.

    And it won't be stopped because you don't need to stop it, you just need to make it wobble a bit and it loses effectiveness.

    A net is very efficient at stopping a ball, but if you think about it a penetrator caught in a net it will twist and tangle in the net and that is the best way to stop a penetrator.... apply a twisting or bending force... think of it in terms of hitting a nail in with one hit...any off angle and the nail bends and does not penetrate much at all.

    For an ATGM it is the same and in both cases could potentially just shear off the tip... bad for a solid penetrator, and also bad for a missile or rocket with a nose mounted fuse or standoff probe.

    If it's more rigid the projectile will just tear through immediately with the only force exerted against it being one pushing straight back against it. Only this force would be so miniscule relative to the speed of the projectile that it wouldn't do anything at all.

    But a loose net on the other hand will exert only a little force/resistance in the beggining, and an angular one at that as the net will bend inwards and upwards as its pushed. The resistence won't be enough at that point for the projectile to tear the net off or punch through it, but enough to change its angle of attack. As the projectile proceeds furtherthe resistance from the net will increase and the projectile will in the end rip through it.. but by then it will be too late and the projectile would already be angled upwards and sidewards relative to its trajectory.
