Provided is a blast-free alternative tool for breaching operations for the intended purpose of cutting metal, including rebar, steel cables, I-beams, thin walled containers, welding doors, and the like. The apparatus includes a flexible and cuttable tube containing metal oxide/metal (thermite) mixture, capable of being formed around a target material and of NONEL ignition. The apparatus can be used to cut, weld, or ignite target material. Protective caps are included with provisions to insert shock tube or time fuse to transmit ignition to first fire mix. A fire proof or flame retardant flexible outerwrap with adhesive (such as hydrogel) or malleable retention wires covers the cutting ribbon for heat and slag retention. In the preferred embodiment, the apparatus is issued/manufactured in rolls or precut lengths.

A squib assembly for a non-electric initiator of an anti-personnel obstacle breaching system includes a housing configured to connect to the igniter of a rocket motor of the anti-personnel obstacle breaching system, a slider assembly slidably contained within the housing and configured to connect to a shock tube of the non-electric initiator, and a pyrotechnic element disposed within the housing. Upon activation of the non-electric initiator, the squib assembly is configured to mechanically puncture a base of a initiator sleeve of the rocket motor and to thermally initiate ignition of the rocket motor.

Container (10) is generally cylindrical except for a longitudinal concave groove (11) extending along its entire length. Upon explosion, the contour of this groove (11) results in a focussing effect on the wall material due to the oblique angle at which the expanding cylindrical detonation wave front impacts upon its inner wall. This produces the forging of a rough rod-like projectile (11.sub.1) which, being coherent, maintains its velocity and consequently travels much further than the randomly shaped projectiles (10.sub.1).

An explosive booster shaped to fit into a blasthole adjacent a main explosive charge is provided. The booster comprises a body containing a charge of an explosive substance with a passage extending inwardly of the body to receive a detonator therein. The booster is configured to alter the shape of a detonation wave generated upon initiation of the detonator. In an embodiment, the booster includes a first and a second explosive substance, with the first explosive substance being shaped and selected to cause an outer portion of the detonation wave to accelerate relative to the remainder of the wave thereby altering the shape of the wave from a generally spherical wave to a generally planar wave. In an embodiment, the booster includes an internal member capable of altering the shape of the detonation wave.

The invention relates to a device on the ignition device of a weapon, which can be triggered, for pressure relief, before or simultaneously with the initiation of the deflagrative reaction of the explosive charge, and has at least one channel that can be opened in a controlled manner and connects the interior of the weapon with the external surroundings of the weapon.

A breaching device includes a body having a tamping material. The body has a target surface that is configured to face a target to be breached and a backing surface that is opposite the target surface. The tamping material is formed of gel and is configured to reflect an explosive force directed way from the target surface towards the target surface.
