A stand-off breaching device (20) for breaching a barrier, comprising a housing (21), an explosive main charge (24) having a barrier-end (25) and a rear-end (26), a detonator (29), and means for initiating the detonator (27) when the explosive main charge (24) is at a preselected distance from a barrier. The detonator (29) is configured to detonate explosive main charge (24) at the rear-end (26) such that the resultant detonation wave propagates through the explosive main charge (24) towards the barrier-end (25) and the barrier being breached. This configuration provides more efficient transfer of explosively generated overpressure towards a barrier, thereby enabling the use of explosive main charges (24) with reduced mass, and the associated improvements in operator safety. The breaching device (20) is particularly suited to use in door breaching operations.

A projectile with selectable angle of attack for increased impact on a target includes an active charge and controllable initiation device for initiation of the active charge, wherein the projectile also includes at least one side-acting impulse motor for tilting the projectile relative to its trajectory from a substantially vertical position, in which the front face of the projectile is directed toward the target, into a more horizontal position, in which the outer surface of the projectile is directed toward the target.

A lightweight energetic weapons pod 2 that integrates to unmanned aerial systems 1 that enables the operator the ability to engage targets without flight degradation. The device utilizes an energetic weapons pod 2 that may be reloaded to support sustained combat operations. The ability of the device to function as intended is based on explosive mitigation compression zones and recoilless configurations that allow drone survivability during detonation events.

A single-trip method and system for perforating casing allows displacement of a heavier completion fluid from the perforation zone by a lighter formation-compatible treatment fluid without the need for an extended rat hole or repositioning the working string. The perforating system includes bridge subs located above and below a perforating gun. The bridge subs bypass treatment fluid around the gun through one or more conduits located along the exterior of the gun into a discharge flow port located immediately below the lower bridge sub. The system may be hydrodynamically designed to maintain efficient fluid displacement characteristics of the discharge flow port. The external conduits are positioned to not interfere with perforation operations and may include parallel conjoined tubes. The perforating system may be lowered to a perforation position in the wellbore, and treatment fluid pumped through the discharge flow port to displace completion fluid prior to perforation operations.

Methods, systems, and devices for an area-denial munition configured for self-neutralization of an explosive ordnance. In one or more embodiments the munition including a housing including a chassis defining one or more openings such that the housing is an at least partially open structure exposing an interior to an ambient environment. In various embodiments the munition includes a detonation module including a detonation initiator and a deflagration module including a deflagration initiator coupled with a pyrotechnic primer, and munition control circuitry. In various embodiments the munition control circuitry receives instructions to deflagrate the explosive ordnance and instructs the deflagration module to activate the deflagration initiator. In various embodiments, the deflagration initiator causes a deflagration of the explosive ordnance for self-neutralization of the munition resulting in safe destruction of the munition's explosive charge and control electronics.

A method of sealing and securing of a shaped charge comprising a casing having a detonator, an explosive filler disposed within the casing having a cavity formed therein, and a liner disposed over the explosive filler. The method includes coating at least one portion of the shaped charge with a curable sealant, and exposing the curable sealant to radiation to cure the curable sealant. The radiation may be in the ultraviolet range and have a wavelength in a range of from about 200 to about 400 nanometers. In addition, the at least one portion of the shaped charge that is coated with the curable sealant may be a surface of the liner, a joint between the liner and the casing, over the detonator, or any combination thereof. The liner may comprise a metallic liner.
