I'm probably not doing myself any favours by publishing this here, but I've attached my AP Penetration Calculator for SPWW2.
I'll tell you what, you only have permission to download it if you don't use it against me on the battlefield.
It's an Excel spreadsheet. You put in the weapon's max pen, max range, and warhead size, and it calculates the base penetration at any range. It's usually accurate to within 1cm.
It's a reverse engineered estimate, because the game designers cannot/have not released this info.
I'll attach it in letter and A4 size, in case you want to print it out as a reference.
Her are some real world tables based on firing range numbers;

Some guy named Byrd ( or Bird, maybe) wrote a massive book on the topic. He found that with the larger caliber weapons, sometimes they wouldn't penetrate, they would just knock that bit of tank into the interior of the tank.
The former tank crew prolly wasn't concerned about the difference.
Thanks - very interesting!

Nope, spalding is just as lethal as a round penetration and is why the new tanks (we put it in our old tanks too) have ceramic sheets put in them. Even just the flakes of paint can cause injury inside.
I'm sorry, I didn't write that correctly. At certain ranges, an 88 would knock the armor loose and push it back into the fighting compartment. Not a chgunk but the whole plate. Shermans were real bad about that. The Armor would break loose next to the weld and keep going until it hit the Armor on the other side. Or wrap around the engine.
There was also something called a "shatter gap". At certain ranges and speeds a round would shatter when it hit the armor. A few meters one way or the other and it was a penetration.
Or so it is claimed. I took all that with a grain of salt. Between Murphy, Mars and Lady Luck, I don't believe that battlefield events can be reduced to formulas that are meaningful. WAG's are about the best one can do.
It is interesting.

I always thought that it was called 'spalling"

Looks nasty.
I guess a big, non-penetrating, HE round slapping the outside of the tank would cause a lot of that to happen. Is that correct.
I heard that early WW2 tanks that were riveted together were really bad for shedding the rivets and turning them into wee projectiles.
Ouch.
yeah, i call it spalding...golf balls bouncing around inside a tank.
I thank you
Cross is at least a cognitive material !
In the calculator not all weapon that is in winSPWW2 ?

You are welcome
Thank you also to my son Jeremy. I figured out what the game engine was doing, and I could use an old fashioned graph to predict results; but I had to ask my son to write the forumlas, and later the Excel formulas, that have made the data easily accessible.
