747 para combate de incendios forestales
The Evergreen Supertanker showed impressive results during the U.S. Forest Service administered grid tests earlier this year. From high, medium and low coverage levels, the Supertanker showed it provides quality, consistent retardant line construction. The cutting-edge aircraft proved it belongs on the front line, from the onset, to fight wildfire day and night. The uniformed pattern of the Supertanker drops, and its ability, in a single flight, for split loads at multiple coverage levels, gives agencies an incredibly versatile firefighting tool.
The multi-role B747 Supertanker is the largest tanker aircraft available today. 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.
