PURPOSE: A long distance firing system for aerial transportation of water and for a prompt extinguishment of fire is provided to achieve an effective water transportation while freezing the water to be shaped as a ball and scattering the ice cannonball after being fired for a widespread deposition of water. CONSTITUTION: A long distance firing system is characterized in that water is freezed to form a ball, and the liquid or solidified gas fired by a pressure of gas generated from a blasting powder, compressed air or gas explosion is guided to reach a long distance so that the liquid or solidified gas scatters by the air resistance.
