A projectile fired from a weapon which has a bore with inner rifling, having a point and a base which are disposed within a sleeve such that the point and base of the projectile rotate independently of the sleeve when fired from a gun or similar weapon designed to discharge projectiles or similar material.

The present disclosure relates to a launch system and method. The launch system and method can include at least a preliminary accelerator tube system (PAT) that can be combined with a main accelerator tube system (MAT). The PAT alone or combined with the MAT can be used for launch of a vehicle for testing and/or for delivery of a payload.

A propellant driven disrupter (PDD) for disrupting an explosive target, comprising: a disrupter barrel having a breech and muzzle end; a projectile liquid or gas positioned in the barrel and extending a longitudinal distance in the disrupter barrel. The projectile liquid distal end is located farthest from the disrupter barrel breech end. A jet stabilizing projectile (JSP) is at least partially positioned in the barrel and operably contacts the projectile liquid distal end. The JSP has a JSP proximal end facing toward the disrupter barrel breech end and a distal end opposed to the JSP proximal end, wherein some or all of the JSP is positioned in the barrel. The PDD may contain the JSP, with an air region between the JSP distal end and the muzzle end, or an air region in an adapter that is connected to the muzzle end. Also provided are JSP's having improved flight stability for use with liquid or air-filled disrupters and methods of disrupting a target.

An integrated propulsion and warhead system for an artillery round includes a propulsion, such as a solid rocket motor and/or an air-breathing jet engine, and an annular explosive concentrically arranged around at least a portion of the propulsion system. The integrated propulsion and warhead system is included in a propulsion section of the artillery round so that space in an adjacent guidance section is increased and the space allocation for the propulsion system and annular explosive is optimized.

A hyper-velocity impact sensor is configured to probe a mass of material consumed upon impact with an object. The probe can extract density and thickness characteristics of the impacted object, which can be used to classify the object.

Muzzleloader systems include a pre-packaged propellant charge and primer for providing efficient loading and unloading of the muzzleloader. The muzzleloader accepts in the breech end the propellant containment vessel that abuts against a constriction portion with a reduced diameter portion. The propellant containment vessel having an end portion with a tapered surface that conforms to the constriction portion surface. A projectile is inserted in the muzzle end and seats against the constriction portion. The propellant containment vessel may be received in a removable breech plug. The constriction portion may be part of the breech plug or a separate component secured in the barrel by way of the breech plug. The containment vessel further comprises a primer mechanism that may be integrated into the proximal end of the containment vessel.

New projectiles specialized for creating and recovering trace evidence at a crime scene are provided. A wide variety of embodiments are provided, covering several use scenarios—including, but not limited to, home security devices, which may be built into an entryway or other building structure, and law enforcement guns. In some embodiments, a projectile within a projectile is provided, which fires in the direction of a primary impact. A sampler device is provided within some projectiles, which may comprise tracing barbs, containers for analytes and even a hypodermic extraction apparatus. In some embodiments, projectiles have rebounding devices, which may overlap with aspects of the sampler device, for developing distance from a criminal suspect. Other aspects, such as GPS, fasteners and defense mechanisms, are also disclosed, which encourage recovery by the authorized user and deter interception.
