IS-7 vs MAUS | 130mm BR-482B vs The Heaviest Tank Ever Made | Armour Penetration Simulation

The German Maus was the heaviest tank ever made, with prototypes being developed towards the end of WWII. Meanwhile, the Soviet IS-7 had its first prototypes made shortly after the war. The simulation presents the impact of the IS-7’s 130mm BR-482B projectile on the lower cheek of the Maus, from close range. The turret cheek of the Maus has been modelled as 232mm thick, in line with Warthunder. However, the only existing Maus was assessed to have a 220mm thick turret front, but there are various sources out there which state that the planned thickness was supposed to be higher -some even stating 240mm. It has been modelled as 220BHN good quality RHA. As the hardening profile is not available for BR-482B, the first set of simulations show the result of the projectile having very good quality metallurgy -similar to some post-war Soviet shells (like later versions of 100mm BR-412D) which have a maximum hardness in the nose of ~650BHN. As this may have not been the case for the IS-7 in the late 40’s, the last two visualisations show the same scenario with the hardness reduced to ~450BHN maximum, with poorer WWII Soviet metallurgy.
