Chieftain vs Object 279 | Armor Penetration Simulation

Simulation of a Chieftain projectile hitting the frontal armor of an Object 279 tank 120 mm L15A3 APDS (Tungsten Alloy core) at 1300 m/s vs Object 279 hull front armor (93-110mm, at 70-75 degrees) Chieftain tank 120mm L11 gun muzzle velocity - 1371 m/s. 1300 m/s refers to a distance of approximately 1.1 km.
