ABSTRACT:
A pyrotechnic chain igniter device for cargo warhead sub-ammunition including an explosive charge contained in an enclosure, comprising a first striker mobile in a longitudinal bore of a body for striking a primer, a slider carrying the primer, the slider being slidably mounted in a transverse groove in the body and being adapted for sliding between a safety position and an armed position, wherein the safety position is defined by the slider being misaligned with the first striker and the armed position is defined by the primer being substantially aligned with the first striker. The first striker is adapted for striking the primer when the slider is in the armed position and when the sub-ammunition impacts a target. At least one device for blocking the slider in the safety position is provided. A trigger is pivotally mounted to the body, and a spring is provided for maintaining the trigger in a first position to prevent the slider from moving into the armed position, and for allowing the trigger to move to a second position upon axial rotary movement of the sub-ammunition thereby allowing the slider to move into the armed position.
