Abstract
An out-of-line water safing and arming device includes an out-of-line barrier assembly with an internal bore. When submerged, the bore fills with water which is entrapped by a hydrostatically-driven piston assembly to cause the barrier assembly to move to an in-line armed position. However, when the device is not utilized but is removed from the water or rises to the surface, the piston in reaction to the decrease hydrostatic pressure releases the hydraulic lock allowing the water to drain out.
