A line charge assembly and system are provided for use in a shallow-water obstruction clearing operation. Each assembly has a propulsion unit capable of flight through the air, a line charge array, an air-safed water-armed fuze, a first interrupter disposed between the line charge array and the fuze, and a second interrupter disposed in the line charge array. The line charge array is defined by a plurality of line charges successively coupled to one another by a detonation line capable of transferring detonation energy therealong successively to each line charge. The line charge array has a first end coupled to the propulsion unit and has a second end coupled to the first interrupter. The fuze generates the detonation energy at the expiration of a first time period provided the fuse is in water. The first interrupter permits the detonation energy to be transferred from the fuze to the second end of the line charge array until the expiration of a second time period. The second interrupter permits the detonation energy to be transferred therethrough until the expiration of a third time period. The first time period expires before the expiration of the second and third time periods. The first interrupter operates independently of the fuze to essentially sterilize a dud fuze. The second interrupter operates independently of the fuze and first interrupter to prevent the back propagation of sympathetic detonation energy to any of the assembly's line charges that reside between it's fuze and the first interrupter in the case where the fuze is a dud.

1. A line charge assembly for use in a shallow-water obstruction clearing operation, comprising;a propulsion unit capable of flight through the air; a line charge array defined by a plurality of line charges successively coupled to one another by a detonation line capable of transferring detonation energy therealong successively to each of said plurality of line charges, said line charge array having a first end coupled to said propulsion unit and having a second end; an air-safed water-armed fuze for generating said detonation energy at the expiration of a first time period provided said fuze is in water; first means coupling said fuze to said second end for permitting said detonation energy to be transferred from said fuze to said second end until the expiration of a second time period and for prohibiting said detonation energy to be transferred from said fuze to said second end after the expiration of said second time period; second means in line with said detonation line between said first end and said second end for permitting said detonation energy to be transferred therethrough until the expiration of a third time period and for prohibiting said detonation energy to be transferred therethrough after the expiration of said third time period; wherein said propulsion unit pulls said line charge array, said second means, said first means and said fuze through the air to a water destination; and said first time period commencing when said propulsion unit begins to pull said fuze through the air, said second time period commencing when said propulsion unit begins to pull said first means through the air and said third time period commencing when said propulsion unit begins to pull said second means through the air, wherein said first time period expires before the expiration of said second time period and said third time period.
