When the mothership transits through a calculated release point the DASH package disengages the mothership.

Abstract: A method of suppressing a wild fire raging towards a target region of land in a direction determined by prevailing winds and other environmental and weather factors. Prior to a wild fire reaching a target region of land, a GPS-guided system is used to apply an anti-fire (AF) chemical liquid mist over a GPS-specified fire break region, in advance of the wild fire and containing molecules that cling onto vegetation and form a fire break region, while providing a non-treated region of sufficient size between the front of the wild fire approaching the target region of land and the fire break region. When the wild fire reaches and moves through the GPS-specified fire break region, the molecules clinging onto the vegetation reduce the free-radical chemical reactions raging in the combustion phase of the wild fire. This reduces the destructive energy of the wild fire, thereby suppressing the wild fire and protecting the GPS-specified target region of land.
