The Evergreen Supertanker has a pressurized system that can disperse retardant under high pressure, or drop retardant equivalent to the speed of falling rain. This system allows the aircraft to operate within its design criteria. Using the pressurized system, the aircraft can deliver retardant to the scene of a fire while flying at a height of 400 to 800 ft, at approximately 140 kts, configured as if it were on approach for landing. The Evergreen Supertanker’s tank system can be configured for segmented drops, allowing the contents of the tank to be released at multiple intervals while in flight.
