A mortar system includes a launch unit that comprises a mortar ignition cartridge provided with a flashtube. The flashtube incorporates a ring-like nozzle that is positioned within the flashtube, which acts to restrain the motion of the black powder pellets as well as to choke the flow of the resultant combustion products. The nozzle separates the flashtube into two compartments: a flashtube venting chamber and a pellet combustion chamber. The mortar ignition cartridge combustion chamber acts as the product-gas venting area of the flashtube. The combustion of the black powder pellets essentially takes place in the pellet combustion chamber. The present design modification improves the overall performance of the mortar system. |

A wad or basewad for ammunition includes an ignition chamber. The ignition chamber can be integrally formed with the payload wad, basewad, or battery cup or can be attached to the payload wad, basewad, or battery cup. The ignition chamber communicates with a primer of the ammunition to receive and contain the primer blast for at least an initial period of time. This facilitates faster initial ignition of the propellant of the ammunition, and consequently allows higher performance levels to be achieved. Other advantages regarding other applications of this invention include cleaner burning loads, greater economy, and lower perceived recoil. |

A multi-caliber fuze kit includes a fuze housing configured for coupling with multiple projectiles. One or more canards are moveably coupled with the fuze housing. The one or more canards are adjustable between two or more canard configurations. In a first canard configuration, the one or more canards are at a first canard angle relative to a bore sight of the fuze housing, and the first canard angle is configured for use with a first projectile. In a second canard configuration, the one or more canards are at a second canard angle relative to the bore sight of the fuze housing, and the second canard angle is configured for use with a second projectile. The first and second canard angles are different. In another example, in the first canard configuration the one or more canards include a first canard shape configured to provide a first specified trajectory with the first projectile. In the second canard configuration the one or more canards include a second canard shape configured to provide a second specified trajectory with the second projectile. The first canard shape and the second canard shape are different. |

A fuse booster system for a reduced collateral damage bomb or penetrating warhead is described and disclosed. The fuse booster system uses shaped charges that will ignite the main high explosive charge of the bomb or penetrating warhead, and also remove portions of the bomb or penetrating warhead to reduce the power of the bomb at the target in a measurable manner to control the lethality and collateral damage of the bomb or penetrating warhead. |

A fuze guidance system is configurable by an end user, allowing the end user to select between different configurations of canards of the system. The different configurations of canards may include canards with different surface areas, optimized for providing appropriate control with different sizes of munitions. The different configurations may be accomplished by having canards with separable portions which may be broken off or otherwise removed by the end user, to reduce canard surface area and/or span. Alternatively the fuze guidance system may come in a kit with multiple sets of canards having different sizes or otherwise having different configurations for providing different aerodynamic characteristics. The end user may select a canard set based on the munition size or type that the fuze guidance system is to be used with. |

A smart fuze system includes a radome used to hold a replaceable smart fuze module in place. An internally-threaded collar screws onto threads on the main body of the smart fuze system. Pressure from the radome presses the smart fuze module against electrical connections in the main body. The smart fuze module may thereby be held in place without potting material, allowing different types of fuzes to be swapped into place. The different types of fuzes may include a type that communicates height of burst (HOB) information a type that communicates telemetry, and a type that communicates both HOB and telemetry information. |

A MEMS mechanical initiator having a striker arm extending from a striker body. The tip of the striker arm is adjacent to, but does not touch, the side of a microdetonator. A cocking and release mechanism moves the striker body such that the striker arm pulls away from the side of the microdetonator against the action of a set of springs connected to the striker body. Thereafter the cocking and release mechanism releases the striker body such that the tip of the striker arm swipes the side of the microdetonator causing initiation thereof. |
