Fragmentation properties of the continuous and discrete shield are compared experimentally for the impact velocities of ~1.6-3.7 km/s. It is shown that the projectile fragmentation on the discrete shield, at the certain values of its geometrical parameters, can begin at smaller velocities of impact, than it occurs on the continuous screen equivalent on mass. In the process, an ablation of the projectile mass can make up to 50% from its initial mass.
