Abstract
A spinning tubular projectile (STUP) is subcalibre to reduce both retard and the gyroscopic stability. The total effect is to reduce crosswind sensitivity and to obtain a better ballistic match with an armour piercing fin stabilized, discarding sabot (APFSDS) round. To reduce the range to that desired for a limited range practice round, the STUP is equipped with spin-damping fins on its surface near the projectile center of gravity.
