Abstract : Tests were conducted to determine the penetration of high-fineness-ratio projectiles into thick targets. The projectiles were copper rods with diameters of 0.0044 inch, 0.0029 inch, 0.0014 inch, and 0.0007 inch, and lengths of 0.200 inch, 0.300 inch, 0.500 inch, 0.700 inch, and 0.750 inch. Fineness ratios ranged from 69 to 1000. Targets were 1/2-inch- and 5/8-inch-diameter 2017-T4 aluminum spheres. Impacts occurred at a nominal velocity of 15,000 feet per second. Projectile inclination angles were varied from end-on to broadside.
