Development of 90mm Shot (Armor Piercing), Fin-Stabilized Discarding Abot, for the Defeat of Armor. Addendum

Abstract

It appears that an arrow projectile is superior to a standard projectile fired from a rifled gun. This superiority is in both the terminal ballistic effect and in the fact that the projectile is fired at a higher velocity, which sould improve the probability of first round hit. It also appears that the performance of present arrow projectiles can be significantly improved upon, whereas, it does not appear that rotated projectiles can be significantly improved upon by changing shape, metallurgy, etc. It further appears that arrow projectiles will not fail at particular ranges because of a phenomenon known as 'shatter' in projectiles. Th arrow shell breaks up in penetrating armor, but the so-called 'shatter gap' area of ineffectiveness does not appear, since the velocity level is well above that of the 'shatter gap'.
