    The rocket exhausts point backwards and sidewards and the fuel in the centre of the missile burns during flight so the centre of gravity of the missile does not really shift as the fuel burns and the forward force from the rocket motors comes from the centre of gravity too so keeping the missile flying straight and level is relatively easy but the main charge warhead is mounted so far back that there is plenty of empty space in front of it to form a good armour penetration plasma beam that continues the hole the nose mounted charge has started.

    There is a lot of work that goes in to the design of these weapons, they are quite impressive really...

    Isn't nose mounted charge intended to activate ERA blocks? I don't think a small hole created by such a charge would really help in penetrating main armor.

    It is.
    But that is not Garry's point.
    This is an unusual construction, much discussed when revealed. Main charge is located behind the engine, and the cumulative stream forms itself via a shaft left in the middle of the missile.

    This is just another story, where Russkies are far ahead of the US based competitors in all the spheres other than propaganda.

    A large part of it was that they just set their standards for armour and other things higher so on paper the performance might look less, but in practise you wont get less performance, while sometimes you might get better.

    Isn't nose mounted charge intended to activate ERA blocks?

    Yes, but at the time and even today quite a lot of western tanks don't have ERA so that front charge will just make a small penetration... the rear charge is aligned to continue that penetration and not to try to start a new one.

    I don't think a small hole created by such a charge would really help in penetrating main armor.

    It would penetrate some metal and of course heat it up as well, making penetration for the main charge easier.

    The real point is the arrangement of the components was unusual at the time.

    The precursor is not just effective in prematurely setting of the ERA/NERA layer: the shaped charge jet tip is actually way too fast to be caught by even the retreating moving plates that it actually makes contact with the face plate. This is significant, because in theory if there's no external ERA/NERA layer a strong enough precursor that could pierce through the face plate could also prematurely set-off the reactive elements of the internal armor array which is usually some form of NERA. NERA might have some element of multi-hit capability but I doubt it extends to protecting the very same spot. Anyways, without the reactive armor to shatter/tilt/disrupt the offending projectile the rest of the armor is easy - the last layers are really there just to take care of residual penetration and spall. If the reactive layers are defeated the projectile would most likely plow on through.

    Also found the paper I was somewhat referencing from memory from my post earlier:
    https://www.mdpi.com/1996-1944/14/21/6526

    Compared with the DOP when the simulated cabin is not installed, the DOP of the SCJ
    warhead on the steel target is reduced by about 40%; in other words, the negative impact
    of the simulated cabin on the penetration capability of the SCJ warhead is about 40%.
    Compared with the DOP under the best standoff situation, the DOP of the SCJ warhead on
    the steel target is reduced by 76.5%. In other words, the penetration capability of the SCJ
    warhead designed by this research on the Q235 steel target is reduced by 76.5% under the
    combined influence of the standoff and the simulated cabin.

    "Uralvagonzavod" sent a train with a new batch of tanks T-90M "Proryv" to the troops

    One of the main features of the upgraded tank is the exchange of data with other vehicles in real time.


    MOSCOW, May 17. /TASS/. The ceremonial departure of an echelon with the next batch of the latest T-90M "Proryv" tanks for the Russian army took place at Uralvagonzavod (UVZ, part of the Rostec state corporation). This was reported by the press service of the enterprise.

    "Uralvagonzavod has hosted a ceremonial dispatch of a train of T-90M Proryv tanks to the Ministry of Defense of the Russian Federation," the report says.

    UVZ noted that within the framework of the state defense order, the company supplies the troops with both new and upgraded to the level of T-90M "Proryv" tanks. "The preparation and mastering of mass production of these modern armored vehicles at the enterprise has been fully completed, positive results of qualification tests have been obtained," the press service added.

    Heads and employees of the enterprise participated in the equipment handover ceremony. At the final stage of preparation, drawings and letters from the children of tank builders, as well as Orthodox icons, were put into the vehicles as a sign of respect and support for the servicemen.

    Each tank is blessed by the local Orthodox priest, is bestowed with an icon, and for good measure, a token of the kids' well wishes.

    What a way to pump up both machine spirit and crew!

    Naaah, this is a part of PR stunt lol!
    Still does not change the general message.
    Russian MIC is heating up for war, too.
    Considering that it was already in full working conditions, soon we will see not some sort of deliveries, but a stream of new toys for the Russian war machine.

    There should be an new rule: at every cabinet meeting were the military complex is discussed, the finance minister has to get coffee for all fellow ministers. Downstairs. Somewhere. Will take half an hour which should be enough to get the orders trough. Very Happy

    Another batch of T-90M tanks delivered to the Russian Ministry of Defense

    Uralvagonzavod sent another batch of special equipment to the Ministry of Defense of the Russian Federation as part of the state defense order, including T-90M Proryv tanks and BREM-1M armored recovery vehicles

    On the part of bmpd, we recall that the previous batch of T-90M tanks (presumably consisting of ten tanks) was sent by JSC Scientific and Production Corporation Uralvagonzavod (UVZ, part of JSC Concern Uralvagonzavod of the Rostec State Corporation) to troops 16 May 2022.

    At the International Military-Technical Forum "Army-2017" on August 24, 2017, the Russian Ministry of Defense signed a contract with JSC "Scientific and Production Corporation "Uralvagonzavod" (UVZ )for the supply of the first 30 T-90M tanks ("Object 188M", ROC "Proryv-3"). According to published data, out of 30 T-90M tanks of this first contract, ten should be newly built vehicles, and the remaining 20 should have been converted during the overhaul and modernization from T-90 tanks, however, according to other sources, all T-90M tanks must be new construction.

    Under the terms of the 2017 contract, the delivery of 30 of these T-90M tanks was planned in 2018-2019, however, the actual delivery of the first 10 tanks to the Ministry of Defense as part of the tank battalion of the 1st motorized rifle regiment of the 2nd guards Taman motorized rifle division of the 1st guards tank army Western Military District was producedApril 2020 only. Another batch of T-90M tanks was delivered there in November 2020, and another batch was delivered to the Kazan Tank School at the same time.

    At the Army-2018 International Military-Technical Forum on August 21, 2018, the Russian Ministry of Defense signed another contract with UVZ for the supply of 30 T-90M tanks to be upgraded from T-90 tanks and new production, with a stated delivery date in 2019 . In fact, the tanks under this contract were delivered in the first half of 2021, and in August 2021 UVZ Executive Director Vladimir Roshchupkin saidthat over the past period of the year "for the first time, new and upgraded to the level of T-90M" Proryv "tanks in the amount of 26 units were put into operation for the first time." Earlier in March 2021, it was reported that the first eight T-90M tanks handed over in 2021 entered the 27th Separate Guards Motor Rifle Sevastopol Red Banner Brigade of the 1st Guards Tank Army of the Western Military District, stationed in the village of Mosrentgen (Novaya Moscow).

    On June 28, 2019, at the Army-2019 International Military-Technical Forum, the Russian Ministry of Defense signed another contract with UVZ for upgrading another 100 T-90A tanks to the T-90M level, and on August 24, 2021, at the International Military-Technical Forum " Army-2021" a new contract was signedwith UVZ for a period of several years for the supply of T-90M tanks and for the overhaul of T-90 tanks with modernization to the level of T-90M (presumably up to a hundred units in total).

    According to known data, T-90M tanks in the course of a special military operation in Ukraine have been used, presumably, as part of the battalion tactical group of the 27th separate guards motorized rifle brigade since the end of April 2022 in the Kharkiv region.

    With regard to the supply of BREM-1M, UVZ reported that the previous batch of these vehicles was sent to the Russian Ministry of Defense in early July 2022.

    ^ The T-90 video. It amazing that there's one video on English language YouTube with context. Did anyone expect not a single T-90 to be lost in a real war ? Plenty of Abrams were lost in wars. I wonder if there's a " Abrams is way WORSE than you think video"

    I've noticed that YouTube is filling up with cringe propaganda about China now. Their missiles are so bad. The CCP has collapsed

    To be fair armored vehicles, short of truly catastrophic destruction, can mostly still be repaired and rebuilt, and in quite short timespans too. A single tank can be knocked out several times, even changing hands (not just from one side) before its truly out of commission. One of the perks of being situated on the Eurasian landmass is you have direct road and rail access from the battlefield to the factories, so even loose armored carrion can be shuttled back alongside returning carriers to factories, and then rebuilt.

    Censorship is insane, it's totalitarian already.

    Just for the discussion with Airbornewolf about the missile that struck training center of VSU I was trying to look up the video "Calibr hits training center" and every video that is showing how Kokainzy are destroying Russian forces and of course "atrocity" news of Russians bombing civilians. Nothing more. The West is a totalitarian regime, no freedom of speech, no freedoms just Himmler level propaganda and it works. Go on any social media and if you find any Russian poster or content creator you can read russophobic comments or out right Nazism even from Germans.

    I tried using the De-mainstream add-on, but all that did was put news from india in front of me, not much if any from actual creators.
