A grenade fuze assembly includes a fuze body and a striker lever fixed to the fuze body with a pull pin. A circular pull ring is attached to the pull pin. A detent device is disposed on a top portion of the fuze body and a top portion of the striker lever. The detent device includes four sides with a boss formed on an exterior of one of the four sides. The boss includes a curved slot for receiving and holding the pull ring. A pair of opposed locking tabs on opposite interior sides of the detent device engage the top portion of the fuze body. The detent device secures the pull ring to prevent accidental removal of the pull pin when the grenade is dropped and to prevent undesired noise cause by movement of the pull pin and pull ring.

A detonator formed entirely from a plurality of discrete segments of an insensitive energetic composition, each of the segments employed in the detonator being compacted at different pressures from powder and/or granules of insensitive energetic composition so as to form an energetic train which sequences detonation of the individual segments. Initiation of a main charge can only be effected when a last segment in the detonation train is initiated. Detonation starts with a first segment in the detonation train which is produced under the lowest compaction pressure, and then detonation progresses to a last segment compacted under a higher compaction pressure. The first segment can be detonated by a safety fuse or detonating cord, and the last segment can only be detonated by the next to the last segment in the detonation train.

A venting lifting plug is provided for an unfuzed munition having a fuze cavity with internal threads, the venting lifting plug is formed of a threaded ring having both internal and external threads together with a lifting plug having a lifting ring, a neck and a round portion having external threads, external threads on the threaded ring being in threaded engagement with internal threads on the fuze cavity of the munition, internal threads on the threaded ring being in threaded engagement with external threads on the lifting plug, and a threaded joint formed between the lifting plug and threaded ring is soldered together with one or more eutectic materials having a melting point lower than a predetermined critical temperature of cook-off gases from the munition.

A safer flash-bang grenade that yields the state of the art sound intensity, plus a brighter, more intense flash of the order of 13.5 million candela&#x2014;which effect is due to a combination of a particularly efficacious pyrotechnic formulation and a particular reaction chamber design that momentarily retains or holds-back the reaction escape until the desired intensity is reached. The particular pyrotechnic formulation is based upon a strontium nitrate oxidizer in conjunction with an aluminum powder metallic fuel and a sulfur non-metallic fuel. The particular reaction chamber design includes a relatively rigid, non-fragmenting charge holder, with a slip-fit thin aluminum sleeve internal thereof and a shrink fit or other sealed sleeve external thereof.

Flash-bang grenade with greater flash intensity

A stun grenade includes a housing having at least a portion that is not opaque; a light output section disposed in the housing, the light output section comprising a pyrotechnic material; a fuze coupled to the housing, the fuze including a time delay column inserted into the housing; and a noise output section comprising a lower portion of the time delay column and a pyrotechnic material disposed in the lower portion of the time delay column. The light output section and the noise output section are initiated at different times.
