A detonator assembly which includes a holder, a flexible elongate element which is engaged with the holder, a detonator connected to the element, an energy storage device on the holder and a coil arrangement for charging the energy storage device when the coil arrangement is coupled to a variable electromagnetic field.

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.

An initiation device and method allowing power output to be switched between blast generation and splinter generation. The device and method include a cylindrical warhead with a cylindrical, central explosive charge and a tubular perforated mask surrounding the explosive charge, and also with at least two ignition devices, the first ignition device arranged in a region of one of the head sides of the cylindrical charge, and the second ignition device arranged in a region around a center of a longitudinal axis of the warhead, and having a splinter-generating casing surrounding the perforated mask.

A weapon may comprise an explosive charge, an activatable detonation ignition means, an activatable deflagration ignition means, and an ignition device. The ignition device can activate, selectively, the detonation ignition means or the deflagration ignition means. The activated detonation ignition means can cause the explosive charge to detonate. The activated deflagration ignition means can cause the explosive charge to deflagrate. According to one method, the ignition device activates the detonation ignition means, which causes the explosive charge to detonate. If a predetermined event takes place without the explosive charge detonating, the ignition device activates the deflagration ignition means, which causes the explosive charge to deflagrate.

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.

What is presented is a high power igniter comprising an igniter housing adapted to be positioned in a conduit. The igniter housing comprises a containment sub and a nozzle sub that releasably secure to each other. A high wattage heater located in the igniter housing comprises a combustible pellet insertable into the igniter housing for creating a flow of heated gas when the combustible pellet is ignited with a pellet igniting device while the high power igniter is in use. The high power igniter is free from a loose powdered form of combustible material when the combustible pellet is in the igniter housing. The nozzle sub directs the flow of heated gas in the system.

A jet cutter apparatus and method for using a single bridge wire or a plurality of bridge wires to uniformly detonate a booster and thereby cause a uniform detonation of the explosives adjacent to the liners, thereby causing a uniform compression of the liners to form a uniform plasma jet that is substantially radially perpendicular to the jet cutter.
