A multi-pulse propulsion system includes at least one pulse chamber containing at least one propellant for igniting during at least one pulse of the multi-pulse propulsion system, at least one additional pulse chamber containing at least one additional propellant for igniting during at least one additional pulse of the multi-pulse propulsion system, and at least one passive fuzing system configured to initiate the at least one additional pulse. The at least one passive fuzing system includes a sensor and an igniter. The sensor is configured to sense an environmental condition and/or a ballistic condition. The igniter is configured to provide a stimulus that causes ignition of the at least one additional propellant in response to the sensor sensing that the environmental condition and/or the ballistic condition has reached or exceeded one or more threshold values.
