Explosive devices may be formed from hollow members filled with explosive materials. The hollow members may be made of mating halves that are packed or loaded with explosive material prior to the mating halves being joined together. In some exemplary aspects, the hollow members are placed in fluid-filled containers such that the explosive reaction creates a wave of fluid that impacts a target. Components of the devices may be COTS items and items that may be manufacture with 3D printers.

An explosive disruptor system including a disruptor container cavity; a disruptor tube having an initiating explosive chamber extending from a disruptor tube open end to a disruptor tube shoulder and a primary explosive chamber extending from the disruptor tube shoulder to a disruptor tube bottom wall, the primary explosive chamber having a reduced internal diameter when compared to an internal diameter of the initiating explosive chamber; a container cap having a aperture formed therethrough; and a strain relief connector having a body portion with external strain relief connector body threads, the body portion being at least partially insertable through the aperture such that at least a portion of the external strain relief connector body threads extend through the aperture, the external strain relief connector body threads formed so as to interact with internal disruptor tube threads to repeatably threadedly attached the strain relief connector to the disruptor tube.

An apparatus and method of recoil mitigation for a gun mounted on a lightweight platform is disclosed.

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.

A configurable fluid vessel including a flexible bladder having a fluid port through which a fluid such as water can be provided into the bladder. The fluid vessel includes an internal support frame within the flexible bladder to increase rigidity and can be manipulated into a predetermined shape. The fluid vessel is collapsible for storage whilst retaining rigidity when in use. The fluid vessel is particularly suited for use in explosive jet disruptors for tailoring the formation of a fluid jet.

Provided herein are projectiles for use in a propellant driven disrupter device, and associated methods, to neutralize an explosive target. The projectile may comprise a friction reducing container at least partially filled with one or more fluids, fluid mixtures, particles, and other components to provide one or more desired fluid properties to achieve a desired one or more jet parameters upon target impact. The fluid(s) in the container are referred to as highly efficient energy transfer (HEET) fluids do to the improved fluid jet action on target compared to conventional water projectiles. The projectiles and disruptor can be more precisely individually tailored to the target, thereby increasing the likelihood of successful disablement and decreasing the likelihood of inadvertent and uncontrolled explosion.

Disclosed is a firing device for shock tube. Shock tube is a non-electric explosive initiator, well known to those of ordinary skill in the art. The firing device is configured to provide a redundant dual-ignition capability for connected shock tube. In this way, a second attempt to initiate the shock tube can be made immediately following a failed first attempt. To provide this functionality, the firing device includes a primer tray that can be preloaded with two primers. Using an operably connected selector, the primer tray can be rotated between use positions that individually locate each primer for detonation.

A recoil managed disruptor includes a disruptor device having a barrel from which a slug of material is fired. A piston is mechanically coupled to the disruptor device. A housing which supports the disruptor on a positioning device includes a deformable recoil absorber (DRA) constraint. The DRA constraint is configured to receive a sacrificial DRA structure comprised of a semi-rigid material. The piston is responsive to a recoil force produced when the disruptor device is fired to travel along an axial length of the housing and permanently deform the DRA structure within the DRA constraint.
