There's now a company in AZ converting older Boeing 747s for fire service duty, and the fed and several contract firefighting concerns have them. They're capable of 24,000 gal pressurized drops, but they can't scoop, obviously. Prolly not much need for those in this area, but after working some of the fires out west as helitac crew, I can tell ya that what you see there makes our mountain and foothill fires pale by comparison. And then there are the Florida swamp/urban interface fires that'll make you wish for a good ol' Carolina sandhills/coastal fire in a pine plantation. Coulda used 24,000 gallons in one shot several times in those Florida cases.
