Abstract
Abstract A HIGH EFFICIENCY ROCKET MUNITION WHICH UTILIZES THE MOTOR CASE AS THE WARHEAD FRAGMENTATION CASE. THE WARHEAD EXPLOSIVE IS INSTALLED INSIDE THE MOTOR CASE AND PROTECTED FROM THE MOTOR HEAT BY A THIN INSULATOR. THE LETHALITY OF THE ROCKET MINITON IS INCREASED BY THE USE OF UNBURNED PORTION OF THE ROCKET MOTOR AS AN EXPLOSIVE IN THE EVENT IMPACT BEFORE BURN-OUT AND THE STABILITY OF THE SPIN STABILIZED ROCKET IS INCREASED BY DISTRIBUTING THE WEIGHT SO THAT THE AXIAL MOMENT OF INERTIA IS INCREASED WHILE THE LATERAL MOMENT OF INERTIA IS DECREASED.
