These photos were taken by Hiroshi Ando who was one of the drop system operators on Global SuperTanker Services’ 747 SuperTanker, Tanker 944. Earlier this year the company shut down and sold the aircraft to National Airlines, who re-registered it as N936CA and is using it as a freighter. Hiroshi shot the photo above earlier this month when the aircraft was in Hawaii. He said he has spotted the plane a few times there while it was flying on military cargo flights.
Logistic Air purchased the retardant delivery system that was in the SuperTanker and has plans to install it in a nose-loading 747-200 when the aircraft completes maintenance after the first of the year. Their website for the aircraft says “Returning to Service in 2022.”
The day after Thanksgiving, November 26, a wildfire north of Honolulu, Hawaii threatened structures near Kalana Drive and Alu Street. After the report was received around noon 12 pieces of apparatus staffed with about 34 personnel responded.
Two helicopters owned by the City and County of Honolulu assisted firefighters by dropping water that was dipped out of a swimming pool at Kalihi Valley District Park.
Hiroshi said the fire north of Honolulu started about four hours after Coulson’s C-130 Air Tanker 131, N131CG, departed Hilo after the crew stopped to spend the night on their ferry flight from the US West Coast on their way to begin a firefighting contract in Australia for the country’s 2021/2022 bushfire season.
In a news release the Honolulu Fire Department described the fire as “large scale, rapidly spreading” driven by wind. They said it burned about four acres.
In 2018 Hiroshi sent us photos he took of the Holy Fire while the SuperTanker was working on the fire which burned more than 22,000 acres northwest of Lake Elsinore, California.
It is dry in Hawaii. The Drought Monitor classifies conditions in the state as ranging from abnormally dry to extreme drought.
The company is in discussions with prospective buyers for the huge air tanker
Updated at 3:08 p.m. MDT April 23, 2021
The investor group that owns the 747 Supertanker, Tanker 944, is shutting down the huge air tanker. In an email sent April 21 to officials in Colorado, Oregon, Washington, and the federal government, Dan Reese the President of Global Supertanker gave them the news:
This week the investors that own the Global SuperTanker just informed me that they have made the difficult decision to cease operations of the company, effective this week…This is extremely disappointing as the aircraft has been configured and tuned with a new digital drop system and other upgrades to make it more safe and efficient.
Mr. Reese said in the email they are in discussions with prospective buyers, but it was unknown at that time if the aircraft would continue to be configured as an air tanker capable of carrying more than 17,500 gallons or if it would be used as a freighter.
Most of the company’s employees have been furloughed until the fate of the SuperTanker is known.
In an April 2020 letter posted on the National Wildfire Coordinating Group’s website the Chair of the National Interagency Aviation Committee, Joel Kerley of the Bureau of Indian Affairs, wrote to Global Supertanker Services saying the Committee would not issue a seventh interim approval of the aircraft’s retardant delivery system:
The Interagency Air Tanker Subcommitteedoes not support any further interim approvals without correcting some issues originally identified in the 2009 test of the system that included failure to meet coverage level 3 & 6, retention of retardant in the system after drop, aeration of the retardant causing trail off, and inconsistent flight profiles affecting retardant coverage.
Due to the current national situation regarding the Coronavirus (COVID-19), NIAC will issue an eighth interim approval to GSTS. However, NIAC will not support, nor issue a ninth interim until GSTS successfully passes all requirements of the 2013 IABS Criteria. This must be completed prior to December 31, 2020.
Last winter Tanker 944 spent several weeks in Moses Lake, Washington getting routine maintenance and a conversion of the retardant delivery system from an analog controller to a digital version, a change that was requested by the National Interagency Aviation Committee.
Most large air tankers carry up to 3,000 gallons of retardant. The 747 is capable of carrying far more retardant than any other. When first introduced it was listed at 20,000 gallons. Then the federal government certified it at 19,200 gallons. More recently it was required to carry no more than 17,500 gallons. The second-largest capacity air tanker is the Russian-made Ilyushin IL-76 at 11,574 gallons. The DC-10 until a couple of years ago was allowed to hold 11,600 but federal officials now restrict it to 9,400.
The U.S. Forest Service, the U.S. agency that contracts for all of the large and very large air tankers used by the federal government, has been slow to warm up to the concept of tankers that can carry more than 5,000 gallons. The California Department of Forestry and Fire Protection, CAL FIRE, accepted the concept of the 747 and DC-10 more quickly.
We asked the Forest Service for a comment on the demise of the 747. “The USDA Forest Service is aware of this vendors decision,” said Stanton Florea, Fire Communications Specialist for the agency.”The Global Super Tanker is on a Call-When-Needed (CWN) contract for aerial wildland fire suppression.”
In the interest of full disclosure, Global Supertanker Services has an ad in the sidebar of Fire Aviation.
Opinion of a Lead Plane Pilot
I asked a Lead Plane Pilot who has worked with Tanker 944 for his impressions of the aircraft. He is currently active and not authorized to comment publicly:
It’s a specialized tool, and as such it has a niche that it fills and in that niche there’s nothing else any better. That is, it puts out a huge amount of retardant in one pass, and that sometimes can be a great thing. It can travel halfway around the world and deliver product. Having said that it is also a specialized tool in that it isn’t very good at doing the little stuff.
I asked him about the retardant that sometimes trails off after a drop:
That trail off, that’s something they can beat them over the head with, but at the end of the day hardly anybody I know gives a s**t about it. Ok, well, it’s not a perfect tank.
Below is video of Tanker 944 dropping on the Holy Jim Fire on the Cleveland National Forest in Southern California in 2018.
First drop on a fire
The initial version of the Supertanker installed by Evergreen in a 747-100 made its first ever drop on a fire 12 years ago at the Railbelt complex in Alaska in 2009. When Evergreen went bankrupt Global Supertanker bought the hardware and the rights to the retardant system and installed it in a newer more powerful 747-400.
Assisted firefighters in Israel, Mexico, Chile, and Bolivia
In 2016 the 747 assisted firefighters in Israel, and in 2017 it spent several weeks working on fires in Chile. In one day, February 1, 2017 working out of Santiago, it conducted a total of 11 drops on 7 sorties. Six of the sorties were near Navidad and Matanzas 115 miles (185 km) southwest of the Santiago airport where many structures were threatened. The seventh was near Concepcion, 404 miles (650 km) south of Santiago. In total, 138,400 gallons (508,759 l.) were delivered to assist the firefighters on the ground.
The video below shows the effects of air tanker drops in timber. The first part shows a dozer line or road on the edge of the Glass Fire in Northern California. Then you will see where red fire retardant dropped by air tankers has slowed the advance of the fire. When it can be done safely, firefighters on the ground or on dozers will need to construct a bare-earth fireline where the fire has burned into or through the retardant. Aircraft dropping water or retardant do not put out a fire, they can only slow the spread, and only if the wind is not very strong.
Stavatti is proud to introduce the SM-100AT Air Tanker. A clean-sheet-of-paper, new design Air Tanker, the SM-100AT will deliver 4,000 gallons of Fire Retardant with greater efficiency and lower cost than its competitors. The SM-100AT has entered accelerated development. h pic.twitter.com/h7qmJJHNFG

Dylan Phelps sent us these photos that he captured at various Northern California airports in the first part of September as our firefighters were going up against one of the most vicious wildfire seasons on record.
Two C-130 aircraft from the California National Guard were activated July 22 to serve as air tankers using the Modular Airborne Fire Fighting System (MAFFS). They have been available for wildfire support at Sacramento McClellan Airport.
The 747 Supertanker has been flying firefighting missions out of McClellan almost every day for the last week.
The 747 Supertanker (GST944) has completed its assignment assisting the firefighters in Bolivia. It is scheduled to fly back to U.S. Monday night after arriving in South America on August 23.
Tanker 944 is scheduled to depart from Viru Viru Int’l (VVI) at 3:06 PM MDT Monday October 14 heading for San Bernardino International (SBD) with an estimated arrival at 12:04 AM PDT Tuesday October 15. (UPDATE: it appears the departure will be delayed, and the aircraft will probably arrive at SBD Tuesday afternoon.)
The 747 Supertanker arrived in Bolivia at 1:37 a.m. local time Friday August 23 at Viru Viru International Airport outside the capital city of Santa Cruz de la Sierra and began sorties on fires later in the day.
It appears from the photos above that the method of filling the 19,200-gallon tank may be similar to that used in 2017 when the 747 was working on fires in Chile. In that case there was no robust infrastructure for the distribution of water, so the Santiago Fire Department established a system of portable water tanks filled by water trucks. Fire engines then pumped water from the tanks to the aircraft.
