It is also the only aircraft to have a variable pressure delivery system, and is able to perform segmented drops, meaning it can fight more than one fire in a single mission.
It also has loiter capability enabling ground control to direct it to specific areas.
The award is unique because the Supertanker has an 8:1 drop ratio compared to that of all other current fire fighting aircraft, meaning the Supertanker will forever change the way wild land fires are fought.
The Supertanker also has the ability to respond quickly to a variety of environmental and homeland security threats.
Wide area decontamination, soil stabilization, oil spill response, and radiation knockdown are all within the response capability of the Supertanker, making it the most versatile aerial application vehicle in the World.
River Basin, Spain 23 July (EFE). - The drop made by an Evergreen Boeing 747 Supertanker yesterday on the Poyatos fire in the mountainous area of River basin is the first live fire drop made by the largest fire airplane in the world. It was not considered especially effective because the terrain is not appropriate for such a large airtanker. The airplane made a drop on the south flank of the fire yesterday afternoon. The water appeared to evaporate before reaching the ground; T947 had to drop high due to aircraft size and virulence of the flames, according to the advisor of Agriculture and Rural Development, Jose Luis Martinez Pebble. However, the person in charge castellanomanchego said that the aircraft would probably be more effective in terrain less steep and rugged. Thus they have transferred it from the Council of Agriculture and Rural Development to the wildfire people at the Ministry of Environment and Rural Means and Marino (MIMAM). It was emphasized that on the south flank of the fire where the Supertanker made it’s drop, not even the CL415 scoopers of the Ministry could attack the fire directly. So the terrain was so extreme that this drop should not be considered a fair test of the B747 airtanker’s capabilities. In any case, Spain has affirmed that it is thankful to Evergreen for the use the aircraft.
