A method for disposing of propellant containers containing a propellant, comprising submerging the propellant containers in a detonation suppressant liquid, shredding the propellant containers while submerged in the detonation suppressant liquid into shredded propellant container material reduced in size to provide release of the propellant from the propellant containers, and removing the shredded propellant container material from the detonation suppressant liquid. A system for disposing of propellant containers is also disclosed.

Provided is a multi-configuration transportable demolition pouch that includes a cruciform shaped section of fabric with a central explosive containing area and four trimmable flaps, a fastener on each of the flaps, a strap accepting slit, a first and a second strap, a fabric lid and priming hole, and one or more energetic device that can be selected based on desired blast footprint. The pouch can be trimmed when using smaller quantities of explosives to reduce its footprint and facilitate ease of carrying and emplacement. The device has attachment features to aid in transport and to provide proper spacing and attachment points for demolitions and breeching techniques involving multiple charges. The pouch provides components to allow for blast footprint alteration and for water tamping to reduce blast effects to nearby personnel, as well as to increase the efficiency of the explosive charge.

An explosive threat mitigation unit (TMU) stands ready to receive a suspected bomb, enclose it, and contain the explosion if one occurs. An operator protects bystanders and surroundings by putting the suspected bomb in a TMU and then closing the TMU. If the bomb goes off, the TMU mitigates the effects of both the blast and the fragments. One variation has a container, a tube, a cap, and a door. The container includes an opening. The tube, arranged in the container, aligns with the opening. The cap slides through the opening and over the tube. The door slides into place to close the opening and enclose the cap within the container.

A relatively lightweight, modular, blast control system utilizes a plurality of fabric panels that may be joined to form a matrix to protect or control a blast.

Containment vessels are adapted to facilitate blast and dispersion mitigation. According to one example, a containment vessel may include at least one containment layer. At least one expansion member may be coupled to the at least one containment layer to apply a force sufficient to expand a perimeter of the containment layer(s) laterally outward. A closure system may be coupled with the containment layer(s), where the closure system is configured to cinch the perimeter of the containment layer(s) around a target object without manual intervention. Unmanned aerial vehicle (UAV) including a containment vessel, as well as methods of making a containment vessel are also disclosed. Other aspects, embodiments, and features are also included.
