The New South Wales Rural Fire Service apparently thinks their two year trial of two air tankers, a DC-10 and a C-130, was a success, and expect to keep using them for several more years.
The state of Victoria also has been using air tankers from North America during their down under summer for the last two years, an RJ85 and another C-130. Both states have been using single engine air tankers and helicopters for a long time to aid firefighters battling bush fires.
The conversion of the fourth DC-10 into a Very Large Air Tanker is nearing completion. Rick Hatton, the President and CEO of 10 Tanker Air Carrier, said he expects Tanker 914 to be finished with the modification process in June, including the incorporation of their Next Gen tank controller.
Tanker 914 will join the other three DC-10’s that can each hold up to 11,600 gallons of fire retardant.
As firefighters on the ground continue efforts to get a handle on the West Mims Fire on the Georgia-Florida border, the attack from the air has intensified.
The Very Large Air Tanker (VLAT), a DC-10 fitted with a retardant delivery system, arrived Tuesday afternoon but was only able to make one fire retardant drop before low visibility due to settling smoke made subsequent air operations unsafe, officials said.
The aircraft made two 12,000-gallon retardant drops on Wednesday. Extreme conditions are expected to continue through the rest of the week, with temperatures approaching 100 degrees and winds gusting to 20 mph forecast — Red Flag Warnings are also expected to be issued in the area.
The blaze remains the largest and most active currently burning in the U.S., having already charred about 144,000 acres. It remains just 12 percent contained.

Additional air resources arrived on Tuesday to join crews battling the 140,000-acre West Mims Fire on the Georgia-Florida border.
The Very Large Air Tanker (VLAT), a DC-10 fitted with a retardant delivery system, arrived Tuesday afternoon but was only able to make one fire retardant drop before low visibility due to settling smoke made subsequent air operations unsafe, officials said. The aircraft is capable of dumping 11,600 gallons (44,000 liters) of chemical fire retardant in a single run, and it joins more than 700 firefighters and support personnel working to contain the blaze with bulldozers, helicopters and smaller planes.
The DC-10 is stationed in Chattanooga, Tenn., hundreds of miles away from the fire. Though clear across the entire state of Georgia, that location is the closest airport rated to handle the needs of a place its size, officials said.
Crews caught a break on Tuesday — the fire wasn’t as active as it had been of late, though temperatures still hit 96 degrees with relative humidity hovering about 19 percent.
The fire was just a few miles from the DC-10’s base at Richmond, northwest of Sydney, New South Wales.
This infrared video, shot from a New South Wales Rural Fire Service aircraft, shows a DC-10 air tanker dropping on a wildfire in Australia. In the normal video the aircraft disappears in the smoke, but after switching to IR it can be seen again. The water or retardant it drops shows up as black, much cooler than the fire which is white.
In addition to the drop, there is fascinating IR footage of thousands of burning embers being blown downwind. A spot fire can be easily seen thanks to the IR soon after it starts. It later grows very large.
