Abstract: A projectile has a liner forming an interior void, and a core disposed in a first region of the void proximal to a trailing end portion of the liner, with a portion of the void disposed forward with respect to the core. An outer jacket covers a leading end portion of the liner to enclose the interior void. When the projectile impacts a target object, the core travels in a direction of flight through the leading end portion of the liner to impact the object. When the projectile impacts a target surface at a non-zero angle of approach with respect to the normal of the target surface, the projectile creates a deformation in the target surface immediately before the core travels through the leading end portion of the liner to impact the target. This deformation reduces the probability that the core will ricochet off the deformed portion of the surface.

Abstract: A connector including a biodegradable base material and a biodegradable binder material, comprising at least one of a protein and a residue, configured to hold together the base material to form a biodegradable connector element. The biodegradable connector element affects an operational condition of an apparatus the biodegradable connector element is used within. Degradation of at least one of the biodegradable base material, the biodegradable binder, and the biodegradable connector element provides for a limited operational lifespan of the apparatus resulting in the apparatus becoming inoperable. A system is also disclosed.

Abstract: An explosive device contains a water-reactive material that ignites upon exposure to water. The water-reactive material ignites a water-activated fuse that has a predetermined burn rate and length. The predetermined burn rate and length allows the device to sink to a desired depth before exploding. Hence, the device explodes after a desired period of time and/or at a desired depth. Defense against underwater swimmers is an advantageous feature of embodiments of the disclosure. The device can use a forty millimeter (40 mm) form factor, which permits launch of the device from convention grenade launchers.

Abstract: A less-than-lethal (LTL) cartridge is disclosed. The LTL cartridge includes a case, a sabot that includes an end portion configured to fit within the case, and an interior volume configured to contain a teardrop-shaped bladder. The sabot is configured to release the teardrop-shaped bladder subsequent to exiting a barrel of a firearm. The teardrop-shaped bladder includes a leading end, a tapered body with weakened sections to facilitate rupturing of the tapered body upon impact with an object, a trailing end, and a drogue tail coupled to the trailing end.

Abstract: Embodiments relate to a projectile system, method and computer program product for controlling the flight of a projectile to make a course change by approximately 90°, greater than 90° or up to 90°. The projectile system comprises a gun-fired projectile having a body, at least one tail fin, a motor firing during a first flight phase and during a second flight phase and at least one controllable canard. The projectile system includes one or more processors configured to determine a turn maneuver profile to a target during the first flight phase, produce control signals to destabilize the body, create a pitch attitude change for the turn maneuver profile and effectuate a turn of the projectile in a direction corresponding to the turn maneuver profile during the first flight phase. The processors control the motor to start the second flight phase to the target after the turn.

Abstract: A multiple-charge cartridge is disclosed. The cartridge includes an annular casing having an interior void and a primer. A rotatable selector ring is positioned circumferentially about at least a portion of the annular casing. A cam is positioned in the interior void and includes a first charge and a second charge. The cam is coupled to the rotatable selector ring and is configured to rotate about an axis in response to a rotation of the rotatable selector ring. The cam is configured to align the first charge with the primer in response to a rotation of the rotatable selector ring to a first user-selectable position, and to align the second charge with the primer in response to a rotation of the rotatable selector ring to a second user-selectable position.
