The present invention increases the survivability of a helicopter by prioritizing a threat engagement sequence for a laser-based countermeasure system based on the determined relative lethality of each detected visually trained threat (e.g., small arms fire). The system and method defines a plurality of threat effectiveness merit factors, or lethality factors, that are determinable from available helicopter navigation and sensor data, to quantify the danger associated with each detected threat. The system and method then combines the defined lethality factors using a mathematical function, such as a merit function, to numerically quantify the level of threat posed by each threat. The calculated threat values for each of the detected threats are compared to prioritize the threats for engagement by a laser-based countermeasure system, such as a Visual Acquisition Disrupter (VAD) system.

A fin deployment system for missiles and munitions that deploys and activates straight flat fins for roll control authority. The fin deployment system employs numerous design features, among which are the following: A wrap-around fin concept generates space-savings within a projectile body whereby the fins are arranged in a wrapped configuration around a boomtail structure. The fins may be constructed of a super-elastic material; the system eliminates mechanical means of deploying the wrapped fins, eliminating the need for springs to deploy the fins. The fin deployment achieves substantial space savings for increasing the onboard towing capacity of electronic packaging or lethality in the missiles and munitions systems, while at the same time providing a good roll control authority during flight by enabling a straight fin deployment resulting from the use of super-elastic materials.

The grenade is a multi-purpose munition which can be used as a distraction device, like a flash bang grenade, and can be equipped with chemical agent powder for added capabilities. The grenade is also a sting ball grenade and is a less-lethal form of weapon, designed to reduce fatalities in civilians located in conflict areas. The munition is constructed to be low lethality, and capable of being launched from military and law enforcement 37 mm and 40 mm grenade launchers presently in use today. It is designed to be used in multiple roles when lethal projectiles are not a viable or preferred option, such as hostage situations, riots, room and building clearing operations, narcotics interdictions, distraction and diversionary purposes, and as a method of introducing a chemical agent into a small area from a distance. The grenade can be employed from distances over 400 yards, extending the range of the present art, which is 30 yards.

A fragmentation warhead comprising manual selection means for generating larger fragments versus smaller fragments upon detonation. The warhead includes a generally cylindrically shaped fragmenting metal outer warhead within which lies a generally cylindrically shaped explosive charge. Cylindrically arranged ring mechanisms within the warhead may be rotated to select desired fragmentation patterns.

The present invention provides a high-lethality low collateral damage fragmentation warhead. The case is formed of a material that is pulverized upon detonation of the explosive. As a result, the lethality radius of the pulverized case fragments is no greater than that of the gas blast, thus reducing potential collateral damage. Warhead lethality is improved by placing a pattern shaper between the fragment assembly and the explosive. The explosive and pattern shaper have a conformal non-planar interface that shapes the pressure wavefront as it propagates there through to expel metal fragments from the fragmentation assembly with a desired pattern density over a prescribed solid angle.

A counter-flying object system comprising a sensor array including at least one active sensor configured to detect and track the flying object, and a missile launcher configured to launch an interceptor to intercept the flying object, wherein upon launching of the interceptor, the sensor array is configured to determine the location of the interceptor and send said object and interceptor locations to a control system, the control system being configured to provide mission data to the interceptor based on said object and interceptor locations for guiding the interceptor toward the flying object and activating a fragmentation warhead on or in the vicinity of said flying object when a lethality criteria is met.

An anti-personnel projectile launched from a weapon shell required at impact to have a low lethality consequence, in which the projectile is fitted in the shell in a shape characterized by a blunt end in the direction of flight and maintained in this shape by oppositely directed air resistance and propelling forces to obviate a change of shape during flight that might cause a serious injury.

An optical impact system controls munitions termination through sensing proximity to a target and preventing effects of countermeasures on false munitions termination. Embodiments can be implemented on in a variety of munitions such as small and mid caliber that can be applicable in non-lethal weapons and in weapons of high lethality with airburst capability for example and in guided air-to-ground and cruise missiles. Embodiments can improve accuracy, reliability and lethality of munitions depending on its designation without modification in a weapon itself and make the weapon resistant to optical countermeasures.

A munition and method capable of producing real-time selectable effects ranging from unrestricted to low collateral damage. The munition is capable of a directionally focused fragment pattern and limited lethality/damage effects.

An anti-armor projectile has a tail fin boom having an inner hollow area. A warhead made of high density materials is disposed in the hollow area to serve as a kinetic-energy penetrator that is released upon impact to increase the lethality of the anti-armor projectile.

A munition, such as a warhead, includes a penetrator casing for penetrating hard targets, such as a fortification or reinforced building or other structure, with the penetrator casing having reduced-thickness portions. The reduced-thickness portions provide weak points to the casing that facilitate the casing being transformed into fragments of a desired size/quantity when an explosive within the casing is detonated after the penetration occurs, thus enhancing the effectiveness of the munition. In addition, the warhead may have lethality-enhancing materials, such as additional fragments and/or energetic materials, at the reduced-thickness portions of the penetrator casing. The reduced-thickness portions may be holes, such as longitudinal holes, in the casing, or may be grooves on an inner and/or outer surface of the casing. The munition may be a dual-use munition, with the explosive able to be detonated at a burst height for use of the warhead as a non-penetrating area fragmentation weapon.

At least the forward end of the compartment is sufficiently porous that at least some of the payload material will disperse through the forward end but not the ballast material upon impact of the sub-munition with a target.

An improved light gas gun launches a projectile in a light gas atmosphere as it travels through a frictionless barrel to achieve high muzzle velocities, decreased acoustic signatures, and increased ranges. The light gas atmosphere is introduced by a purge valve prior to firing or by a muzzle valve that holds a positive light gas pressure on the barrel and breech. The muzzle valve also routes the majority of propellant gases through a suppression canister, reducing the light gas gun's acoustic signature. The frictionless barrel uses light gas propellant routed through gas bearings to keep the projectile centered in the barrel and preclude the projectile from contacting the barrel walls, eliminating barrel wear. The system includes a projectile assembly that stores light gas from the firing and injects it into the boundary layer, reducing drag, increasing range and lethality, and decreasing acoustic signature of the projectile down range.

The preservation date is June 27, 2019. The preservation unit is: China General Microbiological Culture Collection Center. According to the invention, a gram-negative bacillus is isolated and screenedfrom dead foal disease material collected from a donkey farm in Shandong Province. After purified and cultured, the isolated strain was identified as Salmonella by morphological identification, biochemical identification and cloning and sequence analysis of 16SrDNA. The results of pathogenicity tests show that the Salmonella strain has certain lethality to mice and most notably can cause abortionof pregnant mice. This strain can be used to prepare an inactivated vaccine of Salmonella causing donkey abortion.
