What is the fuel efficiency of the F-22 Raptor? The short answer is “it depends.” A slightly longer, and equally unsatisfying answer is “it’s better at supercruise, and when carrying munitions, but like all high-performance jets, it’s still awful.” Fighter jets are not built for fuel efficiency, and this severely limits their operational ranges, especially their realistic combat ranges. Fuel consumption is heavily influenced by payloads, speed, mission type, altitude, and much more.
