Abstract
A safe and arm device includes a booster base assembly having a booster base housing and a barrier. The booster base housing includes a shaft port extending substantially in line with a longitudinal axis, at least three initiator ports disposed about the axis, and a matching number of explosive transfer paths in respective communication with the at least three initiator ports. The barrier includes a matching number of fire-train transfer ports and a drive shaft. The drive shaft of the barrier is coupled within the shaft port of the booster base housing allowing the barrier to be selectively rotationally positioned about the axis into at least one of a safe position and an arm and fire position, allowing the fire-train transfer ports to be substantially aligned with the explosive transfer paths when the barrier is positioned in the arm and fire position. A booster basket assembly is also provided.
