Challenger 2 MBT - Technical data and Discussion (Part 1)

In game kevlar will give 0.10 ke per 1 mm

The ratio is correct, what you’re forgetting is perspective, the ufp is 330 thick, but you’ve drawn it vertically down.

I want to know the exact length of the drivers mustache first XD

Do you have photos from other angles?

if this plate is 50mm
a^2+b^2=50^2
I will calculate it later

Loving that this thread has gone brrrrrr again.

Thing I’m most excited about in the new update…the CR2 rework

Big improvement, if I got it right!

Changes: 660 instead of 600, Tungsten instead of DU, 19,25 g/cm3 instead of 18,7 g/cm3;

L28

EDIT: Here, I use the density Gaijin gives to Tungsten alloy for APFSDS instead of the one I found on Google. Not as good, but still a huge improvement over L27A1:

L28

Sadly we are missing all the important info. Due to perspective it is hard to tell if 660 is to the end of the penetrator or the fins. We have no idea what is the diameter and the speed.

do we know what the fins measured in, for ex., l26? arent the fins mounting all suposed to be the same length?

well, someone probably knows

I still believe this plate is thicker than 50mm

Yeah i remember seeing figures like that in Steel Beasts for L27A1 which is incredibly accurate as far as im aware.

I wouldn’t use steel beasts, which is funny because their L27 pen figure is the more reasonably figures they have. A lot of rounds are way overperforming just like their armor diagrams.

Like 120mm DM13 reaches almost 470mm of pen which we know definitely isn’t correct.

This is assuming that the figures represent flat armor which is most likely not correct. It’s probably using 60 degree LOS (Line of sight) since that’s standard. Maybe someone knows if it does.

Now let’s say that they’re using 60 degree LOS pen figures, ok then that would make L27A1 worst in steel beast than in war thunder.

Steel Beasts gives L27 610mm of pen at 60 degrees.

War thunder has it at 652mm at 60 degrees.

Note: War thunder star card doesn’t use LOS, if you want los figures, you have to multiply the 60 degree number by 2. L27A1 penning 326 at 60 degrees means it can go through a 326mm thick plate that is angled at 60 degrees equalling 652mm of total armor.

Why do you think this Plate is 50mm?
I tried using the Pythagorean theorem and trigonometric functions but couldn’t prove that the plate is 50mm.
@Fireball_2020 @Baron_Tiberius

The LFP is actually not 90° iirc

Even if it’s not 90 degrees, the difference between the two is too big

What do you get?

if it is 50mm
So it should be 30:40:50
I make a triangle with 330 as the hypotenuse, and we can obtain the other two sides 290 and 155
50:330=1:6.6
I believe this plate exceeds 50

70

Taking the tow hooks as 45mm, looks very close to the plate.
