M1A2 Abrams vs T-80U | M829A2 | Armor Penetration Simulation

Simulation of a M1A2 Abrams projectile hitting the frontal armor of T-80U. 120mm M829A2 APFSDS ( projectile, DU penetrator, ~21mm dia) at 1630 m/s vs T-80U hull front armor: Kontakt-5 ERA (15mm HHA plate, 8 x 4S22 explosive elements) 50mm SHA 35mm Glass Textolite 50mm SHA 35mm Glass Textolite 50mm SHA at 68 degrees 120mm muzzle velocity (M829A2) - 1680 m/s. 1630 m/s refers to a distance of approximately 1.2 km. SHA - Semi Hardened Steel ( 400 BHN RHA) The interior of the ERA block was simplified for technical reasons. Inside there are light brackets positioning explosive elements.
