    Ok, so I should correct this tabel in case M833, Mathos proofs convinced me. How about DM13 and DM23? @Methos?
  2. Militarysta
    BTW - Im not sure DM-13. In green book (Bauman 2006 Moscow) is 220mm/60@ but IMHO it could be overestimated. From the other side - some other polish Autors found in british archves that "unkown" german 120mm KE was able to penetrate 450mm steel from 1km in late 70's... so maybe..

    My resume that what we known (or not) on one picture:
  4. Militarysta
    No idea, on polish side (factory) it's totall ban for photos and talks about this armour. What is again nonsense couse there are open public reserchees papers whit simmilar solutions for light APC But OK, no talk at all
  5. Militarysta
    Ok, it's not my problem to be honest. As I know finish MoD want's to not public armor photos before whole delivery will be ended but somebody on finish exibition day just make photos ant put it in to net. And now is hot phone between factory and MoD who put this in public. Even funny, but for example in Poland posting this photos can be very problemfull, despite fact that they are "somwehere" on the net.

    1984, Leopard 2 in soviet report: As we can see - Soviet assume Leopard 2 armour in 1984 on 400-450mm vs KE and 550-600mm vs HEAT

    I can explain a lot here ;-) 3BM31 and 3BK31M was attempd to incarase penetration in HEAT round without changing working method of cumulative warhed. Now in west we have SC whit 10-12 and even mor CD penetration. In the end of the 80's it was impossible so choosen operation method was diffrend. Precursor in BK31M is just normal precursor - nothing to do here exept that in some sources this precursor have abilitiest to work like in HOT3/PARS so beeing lunched in to target before main round part had optimum stand-off distance. In other - just slinding to have bigger distance. Main charge - here is funny - axuilary cone (second charge) was to just incarase armour penetration. This SC was ignit first and milisecond after ignit was first (main) SC - two jets where joined together and become one long "super jet". Wery sophisticated idea but dead end. Just googled pdf: 23 RD INTERNATIONAL SYMPOSIUM ON BALLISTICS TARRAGONA, SPAIN 16-20 APRIL 2007 STUDY ON TANDEM SHAPED CHARGES TECHNIQUE Huang zhengxiang 1 , Zhang xianfeng

    Polish Pz.511 HE 120mm is orginally polish ammo - developed since 2002. Basicly it's...recalibrated 125mm OF-19 new unitary catrige. Indeed polish industru is looking for programable upgreade of the Pz.511. The problem is that all best solutions are secure by patents. BTW: Polish :Leopard 2PL will have german programable munition standard - the same as for DM-11.

    Serial (not uparmoured Rosomak) after RPG hit in hull side: No KIA, suprise but no WIA too... And serial APC Rosomak side hull armour: slopped at 9@ Armour compositon from external side: 10mm Armox 500T plate+ air gap 75mm + 10mm Armox 500T plate + 8mm Armox 500T plate Later in Afganistan almoust all Rosomak was uparmoured whit Mikanit armour for front hull and turret sides and whit RPG-net for hull sides.
  16. Militarysta
    Well known APC Rosomak in Afgan. version armour: Orginally it was israeli but after that it was produced by polish company "Mikanit": http://www.mikanit.com.pl/produkty/oslony-balistyczne.html Now, we know patent draws and description: Composition: 2 mm HHS + air + 6,7 mm HHS + 5 mm composite + 5 mm composite + 5 mm composite + 3,5 mm HHS + 35 mm air gap + 3,5 mm HHS + 5 mm composite + 5 mm composite + 3,5 mm HHS + 35 mm air gap + 20 mm aluminium + 5 mm aluminium. There is possibility that layout could be 4+3 (composite) and single composite layer can have up to 6mm thick and single HHS layer can have 4mm thickness. Layers can be separate up to 45mm. Accoding to manufacurer this armour can protect against ATGM and RPG's up to 500mm RHA penetration. Whole armour is combat proven in Afganistan - there are known some "Rosomak" whit 3x RPG's hits diretly in to this armour - no penetration at all, no engine damage.

    Orginally polish second generation 120mm APFSDS-T ammo:
  21. Militarysta
    Yes, a lot of. firstly here: http://btvt.info/1inservice/t-80u.htm second - here: http://btvt.info/3attackdefensemobility/armor.htm Second - just ask.
  22. Militarysta
    Whit KE I can agree - IMHO it's more or less correct. But IMHO - CE value is mistaken. I will explain why - even erly Burlington armour give protection circa as 1 (in compare to the same weight) RHA block agains APDS and after APFSDS and 2 (in compare to the same weight) RHA block agains HEAT. Of cource we can discuss it this ratio is insluding backplate and frontplate or for same "special armour" itself but more or less - HEAT protectio will be mucht bigger then you marked. I propose to not break open door and just copied KE/CE ratio from well known M1 Abrams from 1982 - the same armour orgins, teh same year itp: 400mm vs KE 750mm vs CE ratio: 1,875 And finnal it should looks like this:
  23. Militarysta
    IMHO there is no need to use draws ;-) I had masured it by my own hands: Hatch: Upper glastic plate is the same. So 30mm at 8 = 215mm RHA The bigger problem is whit turret roof but it's propably the same.
  24. Militarysta
    Very nice job, but IMHO there is one small mistake: Upper hull plate is no lees then 30mm RHA - the same as turret roof. So both have the same protection.

    Accoding to Bumar-Łabędy it was serial in PT-91M Pendakar (Malaj), so rather the change was introduced. Whad more - CAWA-2 armour was tested for never build PT-97 and "Gorilla" tank. And it was tested and "finnal" product - for welded turret and PT-91MZ Hull. Again - the only one question is about technology change in cast turret whit CAWA-2 inserts. Even Phds Wiśniewski mentioned this in his book: BTW - accoding to Bumar-Łabendy PT-91M (Malaj) have for 30. degree slighty up then 500mm vs APFSDS-T -it's impossible whit old kwarz filter. And as You know - its pointless to melt HHS plate in turret during casting. So fairytails or..change armour
