The Boeing 747 is a converted passenger plane that is owned by Evergreen International Aviation, a firm that owns several air tankers that are contracted out to various state and federal agencies for wildland firefighting. The Supertanker has just been certified for use in this year’s wildfire season.
James Baynes, project manager for Evergreen International Aviation, says the $50 million aircraft carries twice as much fire retardant as DC-10s. When the Supertanker makes its drop of 20,000 gallons of retardent at 500-ft. altitude it has a drop pattern of 3 miles in length and 600 feet wide. According to a press release from Evergreen:
With a payload of more than 20,000 gallons and a response time of 600 mph, it has more than eight times the drop capability and twice the speed of any other federal air tanker currently fighting fires. The Supertanker’s patented pressurized system has the capability to disperse product at high pressure for an overwhelming response, or disperse at the speed of falling rain in a single or several segmented drops. This pressurized system will also allow for drops at higher altitudes, creating a significant safety buffer and enabling the Supertanker to fight fires during the day and at night, when they are most vulnerable. It also offers a significant value for American taxpayers; saving homes, natural resources, and most importantly, lives. When employed properly, the Supertanker has the capability to save the U.S. government billions of dollars in fire suppression, natural resource losses, tourism, and rehabilitation costs every year.

The Associated Press has this video report on yesterday’s demonstration:
Currently, the largest air tankers in service are DC-10′s. Evergreen, based in McMinnville, Oregon, plans to convert as many as 10 of the 747 jets to fight fires worldwide. They already own dozens of cargo planes that they contract for world-wide businesses.
