in Israel The Global Supertanker was equipped with a pressurized liquid drop system, which could disperse
fire retardant under high pressure or drop retardant at the speed of falling rain. Using the pressurized system, the aircraft could deliver retardant to the scene of a fire while flying at a height of , at approximately , configured as if it were on approach for landing. The Supertanker's tank system could be configured for segmented drops, allowing the contents of the tank to be released at multiple intervals while in flight.
Operation The Supertanker can operate from any airport with an long runway and suitable facilities. Regulations allow for five individuals that are not crewmembers to be carried in the upper deck. This area could be used for command and control, mapping, incident monitoring and video/communications operations. In December 2010, the Supertanker was deployed to Israel to fight the
2010 Mount Carmel forest fire. This was carried out along with crew and utilities donated by other international fire agencies. On June 9, 2011 the Supertanker was also deployed to fight the
Wallow Fire in the US state of Arizona which was at burned and uncontained at the time. Since May 2016, Global SuperTanker has been based in Colorado at the
Colorado Springs Airport, chosen in part for its convenient location for quick deployment to the western US and necessary infrastructure for the large and heavy aircraft. Just a few weeks later, the company was awarded a one-year contract from nearby
Douglas County to assist with wildfire containment. In November 2016, the newer N744ST 747-400 Global Supertanker was deployed to Israel to help fight the wildfires raging in the northern port city of Haifa and elsewhere throughout the country. In January 2017, the Global Supertanker was deployed to
Santiago, Chile, to help the local authorities to combat one of the biggest series of wildfires in the country's history. The wildfires in the south of the country, at the time of the arrival of the 747-400, had burnt more than of forests and hundreds of houses. The operation of the aircraft was the initiative of philanthropist Lucy Avilés and her husband Benjamin Walton, who funded the costs. In September 2017, the Supertanker was contracted by Cal Fire. In December 2017, the plane was leased by Cal Fire during the
late-2017 wildfire season with most drops over the
Thomas Fire. In July 2018, the Colorado Division of Fire Prevention and Control signed a CWN contract to use the supertanker over US Forest Service lands. This followed media inquiries earlier in the summer as to why the supertanker wasn't contracted to fight the fires burning in its home state. In November 2018, the Global SuperTanker was deployed to northern California to assist with the out-of-control Camp Fire in Butte County. ==Evergreen financial difficulties==
