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

Abstract

On the basis of the progress made to date in the development of the APFSDS shot, the following conclusions have been drawn: (1) a new theory of penetration of armor by armor piercing shot has been established; (2) four in. of rolled homogeneous armor plate at 55 deg. obliquity at 2000 yds., or 4 in. at 60 deg. obliquity au 1000 yds. can be defeated using the present M-36, 90 mm rifled gun. (3) five, or possibly 6 in. of rolled homogeneous armor plate at 60 deg. obliquity at 2000 yds. could be defeated with an improved 90 mm smooth bore gun system; (4) smooth bore tank weapons will lead to improved interior, exterior and terminal ballistics for tank ammunition; (5) from a stress point of view the fin stabilized shot can be launched at higher velocities than a spin stabilized shot; (6) the probability of a first round hit is greater with a fin stabilized shot than with a spin stabilized shot.
