The present invention relates to the military field. It discloses a contact fuse for multi-purpose aircraft ammunition, characterised in that it comprises an electromechanical arming system that is easy to manufacture and does not contain any explosive material inside of same. In addition, said fuse is characterised in that it comprises an alert system that reveals a possibly unsafe condition on the ground and in that it is structurally straightforward to manufacture.

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.
