Abstract: Components of a projectile are held together by a captive collar that is internal to the projectile. The internal captive collar is rotated about a central boss, allowing external threads on the collar to engage one of the mating components and pull that mating component into the other mating component in an axial only translation. The internal captive collar is rotated using a geared-key during assembly. This key engages a geared crown feature of the captive collar, allowing it to rotate. After assembly, the gear key is removed from the assembly. Castellated features nest within slots to transmit torque in the assembled projectile.

Abstract: An explosive breaching device is made from a surplus bomblet. The bomblet includes a shaped-charge liner, a steel fragmentation case with an open end, explosive material disposed between the shaped-charge liner and the steel fragmentation case, and a fuze. The fuze of the bomblet is removed and a shock-attenuating case is fixed adjacent to and coaxial with the steel fragmentation case. The shock-attenuating case may be made of a material having a speed of sound that differs from the speed of sound in the steel fragmentation case. A mild steel housing is fixed around the shock-attenuating case. A retaining sleeve may be fixed to the mild steel housing. The explosive breaching device may be mounted in an aiming device to direct the shaped-charge jet in a desired direction.

Abstract: A new mortar projectile for use to resupply various payloads to distant troops. The mortar projectile has the capability of rapidly and accurately transporting the payloads to forward disposed combatants without interference of terrain or enemy action. The mortar projectile includes a shell body for housing the payload to be delivered, and a GPS-guided parafoil for delivering the payload to the designated remote target location.
