KC-46 Tanker's Fuel Consumption Misunderstood by Miles Per Gallon Metric
The KC-46 Pegasus, a tanker aircraft built by Boeing for the US Air Force, has a fuel consumption rate that is often misunderstood. While it may seem to burn through four gallons of jet fuel for every mile it flies, this calculation is overly simplistic and doesn't account for the complexities of the aircraft's mission.
The KC-46's maximum range is 6,385 nautical miles, but its actual fuel consumption varies depending on factors like payload, reserves, weather, and mission requirements. The Air Force measures the aircraft's usefulness in terms that have little resemblance to miles per gallon, focusing instead on its ability to deliver fuel to other aircraft.
The KC-46's fuel capacity is inseparable from its refueling equipment, with no separate tank holding the fuel meant for delivery to receivers. Instead, the same overall fuel supply supports both the tanker itself and the aircraft it refuels, making traditional fuel consumption metrics less relevant.
