?

aramid fibers or some sort of  fiberglass ?

read some british report about M4A4, it syas that bow machine gun have bronze(on second photo shield is painted yelow, but ball look like bronze?) parts C and BB, does all shermans have same ? and is there any good blueprint or measures of B(shield) part(1-2 inch thick?) ? 

maybe someone found pdf of this presentation ?

Ok, you call it harsh, I call it fucking stupid! Disregarding tanks just because of nationality kills your credibility like nothing else, so he is just a fucking troll in my regard.

 

you can call whatever you want

and about so called "credibility", when someone thinks that some tank are 100% better than others, and doesn't  think that all tanks are equally shitty, well, that's where your "credibility died"

how many claims about superb Leo2 armour was made before Turkish Leo2 get in Syria, and swedish report ? and where all this "credible sources and claims" now ?:) 

still don't understand where you can find 400+ but ok

As far as i could see, the length of the upper part of the mantlet is about 510 mm, including the overhang.  The maximum thickness from the front to the back seems to be 420 mm not including the overhang.

maybe i'm wrong, but i don't see any "400+"mm varianst for this measure 

mantlet itself was designed long before Leop2A4, so it's level of protection could be very low, so i  doubt in your optimistic assessment 300mm vs KE

Any feedback would be appreciate.

 

if you take a closer look at the measurements of mantlet done by Militarysta, you will understand that there is no 420, or 400, or even 390mm in it for example...

HSX 130 steel is offered with a maximum thickness of 45 mm (like shown in the German document mentioning HFX 130) and has a hardness of 395 HB on average

 

 

 

 

Soviet BTK-1 and BTK-1Sh used on T-80 have same hardness IIRC

(1 Possible solution: 35 mm steel-air gap + 15 mm steel). "

 

not  far from real life steel thicknesses... 

Laviduce, about your scheme with 80mm at bustle  turret side, Leopard-2 never had plates thicker than 45mm, and turret side - spaced armor with 90mm LOS, not 80mm RHA plate, if you do not believe me, you can knock this part in some museum with your fist (of course, if you do not have the opportunity to use USG) and realize how thin the outer plate is there, main requirement for turret bustle side spaced armor - protection from 14,5mm and 20mm, thats all. 

and of course turret roof have only 40 and 20mm plates, not 70...

engineer "rumor" of 620 mm RHAe seem indeed plausible.

CR2 have lower KE protection than M1A1HA which have 600mm vs KE, so CR1 can't have 620 or 550, and if take some numbers from some british reports about CR1, it's hull front for example have less protection than Shir2 with it's "325mm"

but again, all this numbers useless if you don't know which round was used, on which striking velocity etc...

Merkava hull ?

del
 

it's strange, report says that hull special armor weight 1249, so "A" part on scheme can't be fuel cell ? but without big fuel cell how far type90 can ride ? 

maybe i'm wrong, may someone translate it better?

I think all the PDF u can download in there: http://www.zhuangjiacheliang.com/forum.php?mod=viewthread&tid=679&extra=page%3D1

 

can you upload it  somewhere ?(it require a registration)

Thank you very much for this information. The turret modules seem to be asymmetrical, making one potentially heavier than the other. Anyway, from where did you get this ?

google "90式戦車" and found this

https://www.zhihu.com/question/59141011

scroll down or try to find this "PS:10式" in text 

about "armor modeling", main idea is simple if you get very complex and not optimized( have irregular thickness on welded constructions)shape of armor module then you might be wrong

and btw there is some scheme claimed that hull front - fuel cell, don't know is it BS from modelers, or really Type 90 have this

It is nothing but an opinion, better to find some internal photos or drawings. If so it is rather "strange" design.

you can try to find some armor near the GPS and gunner prism
