Abstract: Instrumented M374 projectiles were launched into snow, nylon, and Styrofoam targets using a 10. 7-m radius centrifuge. For snow of 410-kg/m^3 density, the 3.1-kg test projectile experienced decelerations of approximately 220, 400, and 550 m/s^2 (at a depth of 0.1 m) for initial impact velocities of 15, 30 and 46 m/s respectively. These values disagree with values predicted from a simple hydrodynamic drag force approximation. The decelerations measured for snow targets were always greater than those measured for nylon shaving targets (of density 120 kg/m^3) indicating that this material is not a good analog for snow of the density used in these tests.
