And how does only half the capacity (600gpm) translate to “better boom” C-5s, C-17s, B-52s, E-3s would be have to be coupled to that boom all day to get enough fuel

thats 4380 pounds of fuel transfered per minute. at 600gpm which is what the kc-10 transfers at.

the Boeing KC-767 transfer rate of 900 gpm is 6570 pounds of fuel per minute.

and most take between 10-40k pounds of fuel. wow thats a real long time NOT

The 600gpm is the rate for fighters

the Boeing KC-767 transfer rate of 900 gpm is 6570 pounds of fuel per minute.

Sorry no.

air-attack.com:KC-767-GlobalTanker "The fuel transfer rate for the centerline hose and boom is 600 gallons per minute and the wingpods at 400 gallons per minute."

airforce-technology.com: KC-767 Tanker Transport Aircraft "The boom can refuel at the rate of 600gal/min, the centreline hose at 600gal/min and the wingpods at 400gal/min."

That's using the 5th generation boom, which is OK for Italy and Japan as they only have fighters.

For the US requirement Boeing have promised an imaginary 6th generation boom at 900gpm, but at the moment it's brochure-ware.
