    Sorry i meant to say that the difference in velocity is almost non existant when DM53 is fired from L44 gun (1670 m/s).
  2. alanch90
    Well yes, the claimed number to me is suspiciously low, since the weight and dimensions of BM60 are virtually the same as DM-53 while muzzle velocity is only 100m/s lower than the german round fired from L55 gun and virtually the same as when fired from the L44. And the penetration of DM-53 is claimed as 700-650 respectively. What i find curious is the claim that BM60 defeats ERA (2nd gen? 3rd gen?), perhaps its segmented as DM-53?
  3. alanch90
    Yeah and there are other fishi things with that picture. But in any case perhaps the public performance of "600mm" for Svinets-2 is just an absolute minimum since western tanks have had stronger turrets than that for many years, even decades. On the other hand i can´t imagine how the projectile is adapted to defeat ERA (it doesn´t pack the same kinetic energy as DM53 or M829A3).

    By before i mean this (which of course i never could verify its authenticity)
  5. alanch90
    A little lower than what was claimed before, right?
  6. alanch90
    Both things are not mutually exclusive. If you had the chance to upgrade your older tanks to a protection level similar to your newest and shiniest for a low cost, would you miss it?
  7. alanch90
    I think it's more likely that its additional armor to get to C levels without having to manufacture a new turret.

    More conflicting reports about the development of the engine meant for the Armata family, according to this source the development has failed. https://xn--b1aga5aadd.xn--p1ai/2020/Уралвагонзавод2/ This is legit or fake news?
  9. alanch90
    Souldn´t Svinets be BM-59 or 60? Because this one reades "BM-66", what's going on?

    Seriously, their obsession with Wundewaffes that get systematically canceled (or totally downscalled in service numbers) is the cause they get stuck with older equipment that is not on par with the latest the potential enemies field. At this point the most rational thing the Army could do in terms of time and money, as a stopgap measure until the Bradley replacement starts fielding in some decades, is modernize the M2 (there are several demonstrators and examples) and replace the turret with an unmanned one with the 50mm. That should free enough space in the vehicle to carry at least 2 more infantrymen. Simmilar to what the brits did with the Warrior and the russians with the BMP-3.

    Someone should make a meme with the scene of Pentagon Wars where the guy in charge laments "This was going to be so beautiful"

    Just by looking at the missiles both systems shoot i can already guess which one is the most expensive. But the radars on the Pantsir are huge compared to the Tor (and also claims a much better capabilities in that regard) so i just don't understand why instead of having two separate system that fulfill similar missions they didn´t unified the best components of each one into a single weapon system.
  13. alanch90
    Well that depends on the vehicle that the system is mounted on, both can be mounted on tracked or wheeled platforms. My question is why Tor was selected to go with maneuver units while Pantsir was assigned to other types of formations. I know that there was an article about Pantsir underperforming in Syria, but if it´s true that the system is useless, then why are the russians buying new ones?
  14. alanch90
    I just wonder, i know next to nothing about air defense, at least on the paper the latest version of Pantsir is much better than the latest Tor (range of detection and interception of targets, for example). But if that´s indeed the case, what makes Tor preferable for SHORAD in various units of the Russian Army?
  15. alanch90
    Dammit. Feel free to delete the comment.

    This was just posted on facebook: first look at T-14 thermal signature. What is really interesting is that the frontal Monolith "ERA" and side modules (forward of 2S24 blocks) seem to emit heat.

    Ok since i developed some kind of an obsession for counting pixels i had to make an estimation for the Merkava 4 UFP thickness. Of course the results are just estimates because angle of the image and all that. I have to say that the results are very close to what @Mighty_Zuk came up with many many pages ago. EDIT: as an added comment, given these numbers i don't think that we should consider Merkava 4 UFP as "thin" compared to other MBTs. 600-650mm LOS is thicker than UFP of soviet made MBTs such as T-80 and T-90. Now, how this physical thickness translates into protection effectiveness is another issue entirely.
  18. alanch90
    Details of Merkava Mk 4 UFP, the forward section. Perhaps someone can make a thickness estimation based on this.

    More like NxRA. I remember that in a patent by Rafael (patent number US 7,360,479 B2) they were explaining the advantages of newer types of reactive armors and listed both NxRA and SLERA as the best compromises between ERA threat defeat and NERA multi shot capability (with NxRA being better in this regard). I guess that in theory you could optimize NxRA to either release all its energy contained in its energetic materials in a single instance (thus working like an ERA tile) or across several shots, thus working more like NERA. Also i remember this article http://igorrgroup.blogspot.com/2010/06/russian-nxra-for-lavs.html?m=1 stating that reactive armor based on energetic materials was being explored by the russians for some time: "An attempt to raise the efficiency of the reactive armor led “NII Stali” to creation of so called energetic materials. Energetic materials are a new class of protective materials, which stands between conventional ERA and reactive armor. R&D conducted in “NII Stali” has shown that when the shaped charge jet impacts the energetic material enclosed between metal plates, in the interaction zone which is as small as 60-120mm, a chemical reaction takes place with release of a considerable amount of energy. The energy release rate is comparable to that of the best plastic explosives. It’s about 5000m/s in the interaction zone, and decreases to sonic speeds with the distance from the epicenter. It prevents the shift of the process to the stage of the steady-rate detonation. The efficiency of such systems is much higher than that of other reactive armor systems discussed above, because all the energy released in the local zone is directed to destruction of the shaped charge jet... This type of reactive armor is called NxRA abroad, which means it doesn’t use any explosives; it’s used in a variety of different armor systems (SLERA, LRA, IRA etc.). The use of this approach in reactive armor designs with multi-row cluster order of energetic elements with different levels of energy release allows control of the interaction process and adaptation to particular parameters of the shaped charge jet, which results in increased protection. Energetic materials can be based on different formulations. Due to selective sensibility to the shaped charge jet energy, the energetic materials are effective against tandem-warhead rounds and long-rod penetrators of APFSDS.The ideas of such hybrid reactive armor abroad are implemented only for protection against single-warhead chemical energy projectiles and kinetic-energy projectiles of small-caliber guns. Russian designers are pursuing more ambitious goals for hybrid reactive armor, and they are very close to creation of really multipurpose systems that provide protection against the complete range of threats, including tandem projectiles."

    In the end, TRADOC was right about T-14 featuring 44S-sv-Sh. Lucky coincidence.

    @LoooSeR i just checked again the footage of BMP-3 with Kinzhal turret firing and ejecting spent cases, those clearly are necked down unlike the picture you shared for the Epokha. So i´m thinking that the Kinzhal is using either the old WW2 57x480mm (necked down 76mm case) or the post war 57x348SR as used by S-60 AA gun, both are necked down but the latter is smaller while the Epokha is using a brand new even smaller 57 cartridge.
  22. alanch90
    So in the end both the "Epokha" and "Kinzhal" share exactly the same 57mm cartridge? I thought that the 57 for the Epokha was meant to be of lower power.
  23. alanch90
    @LoooSeR what is that APFSDS in the picture besides the Kornet?
  24. alanch90
    @David Moyes let me get this right. The Cr2 demonstrator has been equipped with the 130mm gun or the round is just there for the sake of being there?
  25. alanch90
    We were talking about APS.
