A projectile (601) for piercing a casing of a mine containing an explosive material, comprising a projectile body having a nose portion (603) and a tail portion (604) and a longitudinal axis, a switch, and electrodes (605, 606) separated such that in use an electrical discharge can flow between them through an explosive material contained within a mine, or to initiate an energetic material comprised between the electrodes to detonate an explosive material contained within a mine. Also provided is a method of mine disposal.

The present disclosure describes a fractal antenna comprising a plurality of antenna elements having a two-dimensional fractal shape and an electrical circuit coupled to the plurality of antenna elements operative to provide electrical power to and maintain phase relationships between the plurality of antenna elements. The electrical circuit provides a signal to the plurality of antenna elements that cause the antenna elements to radiate in the high-frequency (HF) and/or low-frequency (LF) bands. Also described is an antenna comprising a three-dimensional fractal, near-fractal, or super-fractal antenna having a fractal, near-fractal or super-fractal shape.

Various methods and devices have been invented to remove IEDs and tracking devices from substrates such as the body of vehicles. For example, highly localized heat can be used to denature strong magnets or weaken applied adhesives.

A weapons and explosives detector that comprises at least one controlled magnetic field sensor (10) connected to at least one antenna (11); where this antenna (11) is configured as one electrode; and where the controlled electrostatic field sensor (10) is configured to detected a disturbance in the electrostatic field (3) generated by at least one antenna (11) connected with that sensor (10); and where at least one antenna (11) is prepared in a pole (1); or on the perimeter of the vehicle's (2) bodywork; or in an individual combat weapon; where each sensor (10) is connected to at least one control device (100).

A supercavitating cargo round comprises an energetic payload and an electronic payload. The electronic payload includes programmable circuitry suitable for implementing a digital delay of arbitrary length. The supercavitating cargo round is programmable while in a barrel or loader of a weapon.

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 disrupter for launching a combination of a liquid and a projectile toward an explosive device to strike the explosive device to disable the explosive device. The position of the projectile in the barrel of the disrupter determines an exit velocity of the liquid and the projectile from the barrel of the disrupter.

A system for extracting threats buried underground includes a housing, a shaped charge coupled to the housing at one end, and an explosive projectile disposed in the housing and spaced-apart from the shaped charge. The explosive projectile includes an open-ended pipe, a detonation line wrapped about the pipe and extending away therefrom and through the housing, an explosive material disposed about and in contact with the detonation line wrapped about the pipe. The explosive projectile also includes a first donut-shaped plate at one end of the pipe, a second donut-shaped plate at another end of the pipe, and a third donut-shaped plate coupled to and spaced-apart from the second donut-shaped plate. A flow path extends through the plates and the pipe.

A weapons and explosives detector that comprises at least one controlled magnetic field sensor (10) connected to at least one antenna (11); where this antenna (11) is configured as one electrode; and where the controlled electrostatic field sensor (10) is configured to detected a disturbance in the electrostatic field (3) generated by at least one antenna (11) connected with that sensor (10); and where at least one antenna (11) is prepared in a pole (1); or on the perimeter of the vehicle's (2) bodywork; or in an individual combat weapon; where each sensor (10) is connected to at least one control device (100).
