The 747 SuperTanker has received interim approval from the Interagency Airtanker Board (IAB) on January 6, 2017
The 747 can hold 19,200 gallons, much more than any other air tanker. For comparison, the DC-10 very large air tanker carries 11,600 gallons, while the BAe-146, RJ85, and C-130 hold up to 3,000 to 3,500 gallons. The P2V Korean War vintage aircraft that has been the workhorse air tanker for decades usually carries less than 2,000 gallons. The S-2T used by CAL FIRE holds up to 1,200 gallons.
The boast about the most minor things 747-200 carries 19,200 gallons 747-400 carries 19,600 gallons Only 400 gallons more
Didn't the -200 get scrapped though?
The problems still remain with these large tankers that they aren't exactly the best for a lot of the terrain fire can be found in. They're pretty good for a lot of places we have in Alaska I think though.

Evergreen filed for bankruptcy and the sale of the 747-200 tanker (N470EV) was frozen in December 2013 and was sitting intact but idle. In 2015 Global SuperTanker Services transferred the sprayer from the stored 747-200 into a 747-400BCF The -400 has improved engines and will out perform the -200.
