US Patent 10408591 Stackable kinetic energy ring cartridge

A projectile which can be used to defeat an unmanned aerial system. The projectile features sabots which do not impart any forward impedance to the sub-projectiles, and carries a payload of stacked rings enclosed in the projectile. The rings are backed by a support ring, and abut a pusher aft section. The projectile's sabots discard cleanly upon muzzle exit, releasing the ring sub-projectiles to cover a large area, thereby increasing the probability of impacting the target. The rings create large holes in the target, despite comparatively low mass of a given ring as a defeat element, allowing for multiple sub-projectiles to be fired with a single shot, thereby creating the effect of firing multiple projectiles with a single shot.
