Calculation of Armour Penetration
In 2019, the armor penetration system in War Thunder was moved from a documentary basis (where the configuration of penetration was based on data from documents and firing data for each weapon and ammunition type), to a calculation basis using the Jacob DeMarr and Lanz-Odermatt formulas.
The new system is so simple and productive that, if you know the shell’s individual attributes, you can calculate its penetration using the DeMarr formula yourself — right on this page.
All calculations are given for a distance of 0 meters and at a right angle between the shell and armor.
