Abstract: An aircraft penetrating nozzle comprises a penetrator which has a harden tip. The penetrator functions to open a passageway in a barrier or skin of an aircraft to permit the aircraft penetrating nozzle to pass thereinto. The penetrator is securely attached to a frustum which comprises a plurality of nozzles which disperse fire extinguishing fluids interior to the aircraft perpendicular to the longitudinal axis of the aircraft penetrating nozzle and forward of the perpendicular. The frustum is securely attached to a shank which comprises at least one rotating nozzle which functions to disperse fire extinguishing fluid, in fog form, sideways to the aircraft penetrating nozzle which is fore and aft in the aircraft. The aircraft penetrating nozzle is attached to a boom and a fire extinguishing fluid source.
