Suitability of Using Different Types of Shotgun Shells in Defence Against Low-Slow-Small UAV

The suitability of using different types of shotgun shells for defence against low, slow and small (LSS) UAVs (Unmanned Aerial Vehicle) is investigated in this article. The basic criterion for assessing the effectiveness of shotgun fire is the hit probability and the effect of gunfire on the target. When using different types of shotgun ammunition, it is necessary to balance two conflicting requirements. First is hit probability which is affected by the number of pellets in the shotgun shell. Second is the kinetic energy of pellets which is affected by their size and speed. The theoretical procedure for determining the optimal types of shotgun ammunition depending on the distance and resistance of the target is demonstrated.
