  • Publication number: 20160025467
    Abstract: A directed munition has a non-fragmentation casing, and an explosive within the casing that is configured to propel fragments out an opening of the casing when the explosive is detonated. The casing may be made of a material that does not produce lethal or injurious fragments when the explosive is detonated. The explosive may include an insensitive explosive portion that creates the shape of an explosive front, and a secondary explosive containing a more energetic explosive, which is closer to the fragments than the insensitive explosive portion. There may be more of the insensitive explosive than the relatively energetic explosive. The munition may have a ring that is operatively coupled to the fragments, to aid in directing the fragments out of the casing opening in a desired direction. The ring may be made of a material that does not produce injurious fragments when the explosive is detonated.

  • Patent number: 8387507
    Abstract: A weapon interceptor projectile has a deployable frame for maintaining a deployable net in shape. The deployable frame may be an inflatable structure, including a flexible material inflated by a gas generator. The inflatable structure has a perimeter that supports an outside shape of the net, and a series of spokes or arms that couple the perimeter to a body of the projectile. The perimeter may have an airfoil cross-section shape, reducing drag of the frame and aiding in deployment. The perimeter may be have a circular shape, giving the net a circular area. The deployable frame allows the net to maintain its shape during flight, increasing its area and its ability to come into contact with an incoming weapon, such as a rocket propelled grenade (RPG).

  • Patent number: 8173946
    Abstract: A method of defeating an incoming missile, such as a rocket propelled grenade, includes soft launching an interceptor missile, and then using pitch over motors of the interceptor missile to alter course of the missile to a desired interception direction. By launching at a relatively slow speed, such as a speed less than or equal to 40 m/sec (130 ft/sec), the interceptor missile may reach the desired interception direction within 250 milliseconds of launch. The interceptor missile may be able to cover substantially all interception directions over a hemisphere or greater extent around a launch location. For example, the interceptor missile may be launched vertically from a ground vehicle, and be capable of altering course to any above-ground trajectory within 250 milliseconds.
