An explosive disruptor includes a first jacket having joined inflatable members. The inflatable members are adapted to be filled with a gas. A second jacket is surrounded by and coupled to the first jacket. The second jacket has an outer radial wall, an inner radial wall spaced apart from the outer radial wall, and two end walls coupled to opposing axial ends of the outer radial wall and the inner radial wall. A first volumetric region is defined between the outer radial wall, the inner radial wall, and the two end walls. A second volumetric region is defined by the inner radial wall. The first volumetric region is sealed and adapted to be filled with a liquid. An explosive material is disposed in the second volumetric region. A blasting cap is in contact with the explosive material.

Provided herein are mass focusing shaped charges and related methods useful for disrupting targets in either underwater or on land. The mass focusing shaped charges comprise an explosives shell having an explosives shell surface, wherein at least a portion is curved and defines an inner volume configured to contain an inner volume of fluid or a metal liner. A distal body is comprising a SMART material is positioned between the inner volume of fluid and a to-be-disrupted target. A conformable layer of explosives conforms to at least a portion of a surface of the explosives shell, the conformable layer of explosives configured for explosive initiation by a detonator. Upon explosive initiation the inner volume of fluid or metal liner is forcefully ejected to form a fluid or metal jet in a direction through the distal body and toward the target.

An apparatus for use with a disrupter to disable explosive ordnance and improvised explosive devices is described. In a preferred embodiment, the apparatus comprises a sleeve adapted to be fit around the barrel of the disrupter, wherein the sleeve has an opening of generally circular cross section and an aperture for holding a positioning rod; and a positioning rod connected to the sleeve through the aperture for positioning the disrupter in relation to the explosive ordnance or improvised explosive device. The use of the sleeve and positioning rod combination permits rapid determination of stand-off for the disrupter and the angle of impact of the charge the disrupter will fire. The device is particularly useful in disabling pipe bombs.

A modular disruptor cannon includes three open-ended tubular structures. A first tubular housing defines a first interior region longitudinally aligned with a second interior region. The first tubular housing has external-surface threads at a first end thereof adjacent to the second interior region. A tubular insert is fitted in the second interior region. A second tubular housing defines a cap longitudinally aligned with a barrel. The barrel has an inside diameter equal to the inside diameter of the tubular insert. The cap has internal-surface threads for mating with the external-surface threads of the first tubular housing where the barrel is longitudinally aligned with the tubular insert.

The method of controlling recoil in a disrupter comprises: providing liquid in a liquid chamber of the disrupter, the liquid chamber having a front nozzle for expelling the liquid therethrough; providing combustible propellant in a propellant chamber of the disrupter that communicates with the liquid chamber and that has a rear nozzle for expelling combustion gases therethrough; providing a bather between the liquid and the propellant to avoid admixing both; and igniting the propellant to generate expanding combustion gases that will expel the liquid out of the disrupter through the front nozzle in a first direction, either rupturing or propelling the barrier in the process, the combustion gases exhausting out of the disrupter at least partly through the rear nozzle in a second direction, with the first and second directions being at least partly opposite one another to control the recoil of the disrupter.
