Abstract : A safe and arm device, which has an explosive train interrupted by a void to establish a safe condition, has the void filled with a liquid explosive to establish an armed condition. The void may be in a device in which the liquid explosive is motivated by fluid pressure corresponding to free-fall or other velocities. The void may be a chamber portion filled with the liquid explosive by expansion of a bladder. Premature arming may be prevented by forming the explosive liquid from nonexplosive liquids mixed by rupture of a bladder or by melting a solid explosive.
