The Global Supertanker is a Boeing 747-400 dubbed the Spirit of John Muir. It was certified for firefighting flights by the Federal Aviation Administration in September 2016. The Global Supertanker is equipped with a pressurized liquid drop system, which can disperse fire retardant under high pressure or drop retardant at the speed of falling rain. The 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. The aircraft is capable of laying down a swath of fire retardant 3 mi (4.8 km) long and as wide as 150 ft (46 m). A top speed of nearly 600 mph allows it to be almost anywhere in the U.S. in approximately 5 hours. The SuperTanker can be almost anywhere in the world in under 20 hours.
