Abstract: A 40 millimeter (mm) projectile is capable of deploying a payload out of the rear of the projectile. The projectile carries the payload an extended distance from the muzzle and then disperses the payload after a command is provided to the projectile. The projectile includes a proximity fuze which allows it to sense a target and disperse the payload at a given distance from the target. Alternatively, a time-based fuze or radio frequency (RF) based fuze may be employed instead. The payload may be used against a variety of targets, such as personnel, vehicle or aerial targets. In addition, the projectile could be used as a training device for proximity, preprogrammed or RF-controlled fuzed projectiles.

Abstract: A sub-projectile carrier which uses aerodynamic drag to delay the release of a payload in a tailorable manner to control the spread of the payload over a desired range. A 40 mm shotgun style cartridge is shown for use for counter unmanned aerial systems, and for short range anti-personnel applications.

Abstract: A retaining mechanism which may be launched to capture an unmanned aerial vehicle (UAV) or the like. A projectile deploys dampener arms to stop projectile penetration into the target while forward retention arms deploy to prevent a backward removal from the target. The firmly embedded mechanism might feature tracking means or destruction means, or the target may be pulled away by the tether to be evaluated for information.

Abstract: 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.

Abstract: A rotational variable pyrotechnic delay selector for munitions which permits the selection of various ignition delays. Advantageously, the variable delay selector is configurable for a variety of field conditions and targets and is adaptable to a number of munitions systems and pyrotechnic ignition mixtures and delays.
