The design is responsible for the catastrofic explosions that blow the turret off the tanks, not for the tank being penetrated. The penetration is achieved by making the missiles explode on top of the tank, defeating the thinnest armor versus frontal armor that has 60-100 cm equivalent in RHA steel (they are composite, so thickness is different).
