An explosive ordnance disposal (EOD) apparatus enables a human operator to deliver an EOD neutralization tool via an unmanned vehicle to a target attached to a ferrous or non-ferrous surface, position the tool to the target, fix the neutralization tool in place, and activate the neutralization tool, all remotely so that the human operator is not in danger. The unmanned vehicle disengages from the remainder of the EOD apparatus prior to neutralizing the target so that the unmanned vehicle is not damaged or destroyed. The EOD apparatus includes a flexible web interface that positions a tool holder ring containing the EOD neutralization tool onto the target before finally fixing the EOD neutralization tool into place against a ferrous or non-ferrous surface.

Disclosed is a method and system to provide protection for maritime vessels from multiple threat types including shoulder launched rocket propelled threats, ballistic (howitzer), and larger scale missile systems. According to an exemplary embodiment, the protection system is based on the ballistic launch (from the protected vessel) of an explosive charge(s) aimed ˜5 meters away from the vessel and ˜1 meter beneath the waterline followed by detonation to enable the formation of a water wall. Through the formation of a water wall, incident threats can be initiated (piezo fuze) and passivated through dynamic interaction with the water formation. In addition, the upward velocity of the water wall can enable an upwards rotation of the incident threat changing the orientation of the warhead jet formation (for shape charge warheads) above the vessel.

Embodiments of the disclosure are directed to a shock initiation system for initiating shock in a shock tube for demolition. In some embodiments, the shock initiation system comprises a reusable discharge unit and a replaceable shock initiation platform. The reusable discharge unit may comprise a power source, a timer, a switch, and user inputs and may function to store a time, countdown the timer, and generate and transmit an electrical energy to the replaceable shock initiation platform. The shock initiation platform may receive the electrical energy from the discharge unit overpowering a resistor disposed on the shock initiation platform. The resistor may then detonate providing an initiation shock to a proximally disposed shock tube, thereby initiating shock in the shock tube.

A detonator for a perforating gun. The detonator is used to ignite a detonator cord in a charge tube for a perforating gun assembly, which in turn is used for perforating a wellbore. The detonator includes a cartridge. The cartridge comprises a tubular body having a first end; and a second end. Preferably, the tubular body is fabricated from a metallic material. The detonator also comprises a post proximate the first end of the tubular body. The post is configured to be in electrical communication with a first leg wire connected to an addressable switch. Alternatively, the post is in contact with the end of a detonation pin. The detonator also has a fuse head within the bore of the tubular body, and a fuse wire. The fuse head is in contact with the explosive charge material. The detonator is releasably snapped into a compartment located within the charge tube.

A warhead includes a casing having a periphery wall that extends along a central axis from a forward end of the casing to a rearward end of the casing. The casing defines a cavity configured to contain an explosive material, wherein the forward end of the casing includes a first thread pattern configured to engage a guidance system casing, and the rearward end of the casing includes a second thread pattern configured to engage a propulsion system casing. A first row of fragments is arranged along a first section of the periphery wall of the casing. A plurality of second rows of fragments is rearward of the first row of fragments and arranged along a second section of the periphery wall of the casing. In an example, each of the first and second sections tapers inward towards the central axis as it extends toward the forward end of the casing.

A munition has an explosive charge with direction explosive characteristics, such as a nonuniform detonation velocities. The explosive charge may have multiple portions of explosives with nonuniform characteristics, and/or may have portions with graded nonuniform characteristics. The explosive charge may be used to propel a material from the munition in a desired manner. For example the material may be fragments that are part of a fragmentation munition. Alternatively the material may be a layer of a material, such as a metal, that produces an explosively formed penetrator or shaped charge. The explosive charge may be configured to control the spread and/or direction of the material to be propelled from the munition.
