Tank Armour Thickness Calculation.

[nuffe]

Ok, so apparently the method of calculating the thickness of sloped armour is like this:
'Armour thickness' / cos ( 'sloping degree' )

So if we use this math, we can then see the "real" thickness of the sloped armour. I'll only show the tanks with sloped armour, the boxy tanks arent worth the trouble.

American tank armour.

Stuart frontal armour:
29mm upper armour at 48 degrees = ~43mm.
38 to 64mm of lower armour at 23 degrees = Could be between ~41 to 69mm.

Chaffee frontal armour:
30mm upper armour at 60 degrees = 60mm.
22mm lower armour at 45 degrees = ~31mm.

Lee frontal armour:
38mm middle armour at 53 degrees = ~63mm.
51mm lower armour at 0 to 45 degrees = 51mm to ~72mm.

Sherman frontal armour:
51mm upper armour at 37 to 55 degrees = ~63-88mm.
51mm lower armour at 0 to 34 degrees = 51mm to ~61mm.

E8 frontal armour:
64mm upper armour at 56 degrees = ~114mm.
51 to 108mm lower armour at 0 to 56 degrees = Could be anything between 51mm to ~193mm.

German tank armour.

100mm lower armour at 40 degrees = ~130mm.



POST SPECIAL
TANKDESTROYERS!!!

Hellcat frontal armour:

13mm lower armour at 38 degrees = ~16mm.

SU85 frontal armour:

45mm lower armour at 60 degrees = 90mm.

Hetzer frontal armour:
60mm upper armour at 60 degrees = 120mm.
60mm lower armour at 60 degrees = 120mm.


Boxy german tanks.

Panzer 3 frontal armour:
50mm upper armour at 10 degrees = ~50mm.
50mm lower armour at 22 degrees = ~53mm.

Panzer 4 frontal armour:
80mm upper armour at 15 degrees = ~82mm.
80mm lower armour at 20 degrees = ~85mm.

Tiger 1 frontal armour:
100mm upper armour at 10 degrees = 101mm.
100mm lower armour at 20 degrees = 106mm.

Stug 3 frontal armour:
80mm upper armour at probably 10 degrees = probably ~81mm.
80mm lower armour at probably 22 degrees = probably ~86mm.

Thank me later ;)

you know how it works but i dont think the game does you would think the 120 effective thickness would be able to bounce everything frontally since the highest penetration shooting at it in the medium tier is 99

No, the Pz4s (if thats the one ur alluding to) AP rounds can pen 110mm at a 30degree angle at 100m, while its APCR rounds 143mm at a 30degree angle at 100m... Dunno what tank ur thinking of when talking about the 120 effective thickness.


And to not be quoted wrongly. I am not saying the values in the post are the "Effective" thickness, just how much armour the incoming round has to go through to be able to "penetrate".
This is why I put " " around "real".

To bad I don't think angling your tank works properly, the frontal sloping may have the thickness but I don't think angling increases that thickness.

Actually it does, but it wont help much since we have apcr and what not. And if the enemy tank angles his tank at an angle, we'll just aim for another spot. It will however help with bouncing the incoming shots.

I am quite sure that I have read that angling doesnt increase armor effectiveness, it does increase bounce chance but not armor effectivness.

Update, the boxy german tanks "sloped" armour.
Panzer 3
50 upper armour at 10 degrees = ~50mm.
50 lower armour at 22 degrees = ~53mm.

Panzer 4
80 upper armour at 15 degrees = ~82mm.
80 lower armour at 20 degrees = ~85mm.

Tiger 1
100 upper armour at 10 degrees = 101mm.
100 lower armour at 20 degrees = 106mm.

Armor is pretty much a non factor anymore since everyone now has APCR. I just wish Reto would lower the damage of APCR and slightly increase AP damage for all tanks. So you choose between always penning an enemy tank, but doing less damage, 3-4 hit killing instead of 2 hit killing the enemy. Just to give an example.

Yes, retweak the damage. But not the penetration.

But from what I can udnerstand from what the devs have said on the streams they seem to believe that a higher velocity which = higher penetration also = equal damage to regular Armor Piercing shells and this is certainly not the case... And let's not forget that APCR has worse penetration values against sloped armor than regular Ap rounds, due to the APCR shells being pointy plus some other factors.

I thought it would really help knowing those values :P

Every test you see of AP and APCR rounds is from shooting at a metal target at an angle, 30 degrees etc. NOT 90 degree, flat wall of metal.
AP rounds do more damage, larger hole, since it carries an explosive charge (not always the case), and the metal is softer. The downside is less penetrating power. APCR rounds is just a massive chunk of a bullet comprising of a tungsten core = smaller hole, but greater penetrating power.

WOW you are smart man :D

can you please write this into a steam guide for us?? to be honest your work is awesome
