This 1,000 pound kit was developed at Wright-Patterson Air Force Base, Ohio, to provide quick aid in fighting aircraft crash fires. The tank contained 83 gallons of water and foam, but when this mixture reached the air at the nozzle, it expanded to more than eight times its volume to produce about 690 gallons of fire-fighting foam. The kit could be picked up from its trailer in a cargo sling by an HH-43 crash-rescue helicopter and lifted to the fire site. A heater was mounted on the trailer to prevent the tank contents from freezing when on "ready alert" status at an airbase in cold weather.

An HH-43 "Huskie" helicopter on rescue alert could be airborne in approximately one minute. It carried two rescue men/firefighters and a fire suppression kit hanging beneath it. It often reached crashed airplanes before ground vehicles arrived. Foam from the kit plus the powerful down-wash air from the rotors were used to open a path to trapped crash victims to permit their rescue.
