SU-100Y vs PANTHER | 130mm Naval Cannon on a 1940 Tank | SAPHE Armour Penetration Simulation 

The Soviet SU-100Y was a prototype self-propelled gun, armed with a 130mm naval cannon. While designed to defeat fortifications, the simulation presents the impact of its 130mm SAPHE projectile against the upper glacis of a Panther, from 1.5km.
While the Panther entered service a fair bit later than the SU-100Y, the 870m/s velocity of the 130mm gun would completely overmatch the Panzer IIIs and IVs of the era (so the panther was chosen to make a more interesting simulation). The Panther's upper glacis has been modelled as 80mm thick, 250BHN steel of decent quality. The projectile has the explosive material modelled but it does not detonate, as SAPHE uses a delayed detonation, which would fail in this case due to projectile destruction. This specific projectile is technically Semi-Armour-Piercing High-Explosive Capped Ballistic-Capped (SAPHE-CBC).
