I was looking at one of the Olympus engines and its placard noted that this engine burned 6,300+ gallons per hour at cruise.
As an average fuel consumption, per engine, per hour, calculated over the entire flight and measured in Imperial gallons, that figure is accurate.


Anyone
know if that is with or without reheat?
Without reheat. As others have already commented, Concorde did not use reheat in the cruise, but did use a cruise-climb technique.


I'd be curious how that compares to a modern 747-400 or 777 fully laden at cruise.
Approximate figures for illustrative purposes only.

  • Concorde standard taxi fuel 1,600 Kgs / 440 gallons.

  • Concorde fuel burn LHR-JFK 80,000 Kgs / 22,000 gallons.

  • B747-400 fuel burn LHR-JFK 65,000 Kgs / 17,800 gallons.

  • B777-200 fuel burn LHR-JFK 39,000 Kgs / 10,700 gallons.

Globaliser

a 777 could fly for 14+ hours
Yes, pretty accurate, but what a dismal thought!
