    Armor protection of the tanks of the second postwar generation T-64 (T-64A), Chieftain Mk5P and M60 Technical data on soviet 1-st post WW2 generation of tanks, Like T-54, T-55 and T-62 are well known and well described in literature. But what if Soviet “premium” tanks of 70-s era were engaged into real combat against western tanks in Europre. This article provides description of "Object 432" (T-64) and T-64A tank combined protection (composite armor, anti radiation and chemical protection) in comparison to western designed tanks – “Chieftain” Mk5P and M60A1. Information on T-64 protection includes technical project (presentation) dated 1961 and technical drawings from various periods. Information on “Chieftain” Mk5P and M60A1 tanks is a result of study of captured tanks delivered to USSR in 1970s and beginning of 1980-s, published in technical reports of that period. The importance of information is the common testing criteria based on Soviet approach to tanks testing and protection design. This article contains mostly direct citations of facts and numbers published in reports with some comments. Well, suppose this is a useless task. Prepared a first article in English, but translating this materials is very complex task in question of terms. Will be grateful is anybody assist in corrections of this material (terms and so on). http://btvt.info/3attackdefensemobility/432armor_eng.htm

    It is from an article from VBTT about drum autoloader design

    So the United Arab Emirates ordered German explosive reactive armor for ~125 million Euros. Does anybody know where this is going to be used? Maybe on the Leclerc or BMP-3? What is the source of this ?

    rather ugly made models

    In 90-s Kobra GL ATGM became quite obsolete, so this was a good idea withou limitation of gun calibre and missile size. Some sort of flashback to 60-s era Malutka equiped tanks.

    Some updete on Soviet post war tanks armor, in communist language, but still pictures availible. Soon will be translated into elf's language ) Бронирование современных отечественных танков

    I will translate it soon, briefly Soviets acquired live M60A1 in 70-s and Chieftain in early 80-s. They studied them very closely in all areas. Concerning armor they discovered that Chieftain is not that evil monster they considered. It has maximal 250 mm armor LOS and can be penetrated by T-55 from 500 m, from T-62 from 1600 m and from T-64-72-80 from 3 000 m.

    Results and conclussions of Soviet study of M60A1 (from IDF) and Chieftain Mk5P (from Iran) in comparisson with T-64 (T-64A). http://btvt.info/3at...ty/432armor.htm

    Yes it is local effect (close to the shape charge jet) but it has habit to reflect from tnak internal surfeces.
  12. Andrei_bt
    Concerning shaped charge Beyond-armour effect. The results of soviet tests in 1968 (development of integrated ERA) using pressure sensors and rabbits. In case of penetration of 115 mm HEAT round inside the testing rig sensors recorded overpressure with an amplitude of 0.4 kg / cm2. Such overpressure can be considered dangerous for humans. http://andrei-bt.livejournal.com/469619.html

    Yes I know the sourse is Khlopotov Yes it was not end, but the name is different
  15. Andrei_bt
    Of course can be biger, but tanks do not find like ancient knights at 0 degree head on.
  16. Andrei_bt
    Well, no one said "it was not developed by Russian emigres". But the information of idea of ERA itself is more than possible passed with Blazer. To many coinsidenses.
  17. Andrei_bt
    Biala? Maybe Belka (squirrel) or "white" as you say?
  18. Andrei_bt
    In Soviets protection estimates only 30 degree was taken into account, so it has modest 420 mm vs APFSDS.
  19. Andrei_bt
    Yes it's true - it's just rumors
  20. Andrei_bt
    Well, it's official story. Maybe it is correct, maybe not. It is hard to compare level of Dr. Held works with the Soviet ones which were state supported. From 1968 to 1975 about 100 000 people migrated from USSR to Israel, it is said the one who was mentioned in 1968 report among the Soviet ERA developer is among them.
  21. Andrei_bt
    Thanks for comment, but these are documents, not just someone's opinion. So we have the development of ERA in USSR . It started in 1940-s (first published in 1949). In 1968 test with above mentioned report. One of the developers has the name Blazer. Later he repatriated from USSR to his historical motherland.

    ---Can you please explain this a bit more? According to R. Lindström, the T-80U send to the Swedish tests had essentially the same armor, just slightly different thickness. Hi! I can not explain what did they send to Sweeden, just it's not wat was in T-80U-UD. it's early 219A like on a drawing well known for years. But the above mentioned Swedish picture describes the overall design rather good. Cast plates with holes in them (both sides) filled with resin.
  23. Andrei_bt
    Actualy to understand this pic it is not t-80U or UD, it's early 219A Red is cast metal Yellow is a resin and it is not correct.
  24. Andrei_bt
    Actually it did not lacked the weak point around the driver's position, but it was reduced. It's clear from inside photos. But the level depends on variants.
