  3. Contemporary Western Tank Rumble!

    The Leopard 2 likely had better armor protection against KE than the M1 Abrams,

    it can have, but basic requirements for 2AV after 1977 and first 2A0, is 105mm 38mm APFSDS (https://fromtheswedisharchives.wordpress.com/2019/01/03/rheinmetall-105-cm-smoothbore-performance/ this one), and 120mm DM13 from 1km IIIRC(which is rather poor perfomance round) + protection against Milan ATGM 

     

    all early tanks have "good" protection not because it's have "super-duper-chobham-ceramic-magic-unicorn-armour" but because of shitty APFSDS and APDS used in trials against it at the moment(soviets did it(probably the worst in quality APFSDS and APDS ), americans did it, germans, brits etc), and only after receiving some "emergency calls" like M111 for T-72 etc, "very skilled smart engineers" starts making some improvements over theirs "great inventions" 

     

    and if tank "A" give protection against round "B" in country "C", it doesnt guarantee you that it will protect from round "D" in country "E", and so on...

    poor KE protection.

    all early AFPSDS work not so good against spaced(steel spaced plates) armour, for example you can stop L23A1 point blank on centurion hull front, adding 4 not very thick plates on top of it, with spacing between each plate

     

    all this "360mm vs KE" "over 800mm vs KE" etc useless, unless you know what round exactly was used, and at whick striking velocity armour can withstand that round.

    Yes like this, three plastic fuel cells !  Fuel cell number 4 is the one structural fuel cell behind the driver:

     

     

    I will add the third plastic fuel cell behind the ammunition drum to the model. By the way , from where did you get the last picture? Do you happen to have more of those that you could share?

    btw maybe this will be intersting(cuts in side armour and fuel cell shape)

    Thank you very much Wiedzmin. According to one source this black object near the turret ring  is supposed to be some kind of hydraulic reservoir for the turret traverse and elevation mechanism.   I am not totally convinced of that.  I thought that this black object is another fuel tank. As the book says there is supposed to be another fuel tank at the (upper) back of the hull.  I am missing about 100 liters in my model and this object is the approximate size that would satisfy the requirement. I need a second or third opinion.

     

    The other plastic fuel cells are next to eachother on the hull floor. If you look closely in the opening for the turret connector you will see the fuel lines for those two black plastic fuel tanks.

     

    Also, the object that the one guys has his hand on might  be part of the fire suppression system.

    So is the mythical Kanchan armor just a copy of the T-72's hull armor array with increased thickness (3 x 50 mm layers of glass/phenolic-reinforced plastics vs two layers of 52.5 mm on the T-72M1)? Based on the following text, Kanchan might be only a substitute for the textolite material of the T-72:

    as far as i understand "Kanchan" - term used for designations of various kinds of composite armour, one of it's variants - fiberglass like in T-72/64, some variant uses other materials, and all of this is "Kanchan" so i would be more careful with the statement that "Kanchan armour = FRP only"

    The Leopard 2 with "B" technology armor's lower level of KE protection clearly is a negative factor in real life combat

    in terms of "number vs number" it can be lower, in terms of protection vs certain types of APFSDS it can be anything, that is main problem

    Swedish leaks it seems that the gun mantlet still reaches 350 mm steel equivalent protection vs KE or more when seen directly from the front

    try to draw all "%" on blueprint by yourself(without somebody marks, it can give you independent point of view), and you will understand that mantlet will get in "%" area with "less than 300"

    Btw. according to Hilmes

    Hilmes unfortunately  has a lot of strange words and scehemes in the book, embrasure for main gun on T-72/80/90/64 pretty much the same in terms of weakspot.

     

    2A46M/M1/M4/M5(M4 and M5 gun uses longer barrel guide tube(160mm longer than previous version like M and M1)) , in russian army 2A46 and 2A46M called "green" and "yellow" gun, because of color of paint on gun breech, symmetrical arrangement of recoil devices etc, but T-72A and B more often have 2A46 gun, not 2A46M(mostly because USSR can't support 3 types of tanks with same guns, FCS's etc...)

    Is the extrusion at the top completely part of the proturding edges (as assumed by you) or only partial?

    there was a video from some german factory that demil tanks and IFV's , try to find pics from this factory

    s a copy of Chobham armor,

    i have 2 reports something like 400 pages, maybe more, the only meaning of which is the british mourning the loss of the opportunity to sell the chobham under a license, and an attempt to accuse the germans of having stolen the chobham, and then this great secret was stolen by soviets(which know about such type of armour long before british "invention" lol)
