ABSTRACT:
A pyrotechnic chain igniter device for cargo warhead submunition including an explosive charge contained in an enclosure, which includes a striker mobile in a longitudinal bore for striking a primer, a slider carrying the primer, wherein the slider is slidable between a safety position and an armed position. The safety position is defined by the primer being mis-aligned with the striker and the armed position is defined by the primer being substantially aligned with the striker. The device also includes at least one means for blocking the slider in the safety position and a neutralization means including a trigger actuated by a driving means for preventing the slider to slide into the armed position. Further, the device includes a delayed self-destruct means including a second primer, a delay wick, igniter and a second striker, wherein the second striker is mounted on the slider for initiation of the second primer, the second primer being cooperable with the delay wick and igniter relay to initiate the primer.
