I need help in a hurry again.

Does anyone know approximate fuel burn rates for a C-17?

Thanks so much,.

Nothing explicit, but I found a mention of adding 60,000lb to the fuel capacity for an additional 4 to 5 hours' flight time. That works out to 12,000 to 15,000 pounds per hour.

That comes reasonably close to an unverified capacity statement of 181,000lb and a 5412 mile range. Assuming 480 MPH, that comes out to 17,000+ pounds per hour, assuming no reserve.

Absent better data, 15,000lb/hr looks like a decent ballpark guess.

Ray's guess is better than mine, which was "If you have to ask, you can't afford it"

According to this USAF source, the fuel burn rate for a C-17 is about 21,440 pounds per hour.

Thanks to all y'all.

That came close enough for A speech.
