An airborne fire suppression unit adaptable for installation on an aircraft, particularly a helicopter, for fighting fires in locations inaccessible to other types of fire fighting equipment. The fire suppression unit comprises a fluid reservoir tank mountable on the floor within the aircraft body, a boom assembly having a nozzle mounted thereon adaptable for coupling with the reservoir tank and a motor-driven pump for directing fluid under pressure from the tank to the nozzle, all adapted for rapid detachable mounting to the aircraft. The boom assembly is mountable so as to extend the nozzle laterally from the aircraft, and is rotatably connected at its mounting point so as to reciprocate laterally with respect to the aircraft. The nozzle is pivotally secured to the extended end of the boom to reciprocate in a substantially vertical plane. Manually powered control means operable from within the aircraft regulate the position of the boom assembly and nozzle respectively. A suction conduit coupled with the pump inlet port and adaptable to extend from the helicopter into a body of fluid is provided to permit rapid refilling of the reservoir tank while a fire is in progress. Selectable valve means coupling the pump with the nozzle, tank and suction conduit respectively permit the pump to direct fluid either from the tank to the nozzle for fire-fighting purposes or from the suction conduit to the tank for refilling purposes, or alternatively recirculate the fluid through the tank when neither the nozzle nor suction conduit are being utilized.
