A B-52 bomber gulps down 86 barrels per hour. F-4 Phantom fighter/bombers devour 40 barrels per hour. At peak thrust, F-15 fighters burn 25 gallons per minute. An F-16 jet on a training mission ignites more fuel in a single hour than the average car owner consumes in two years.
To reach supersonic speeds, a pilot turns on the plane’s afterburners which can triple a jet’s speed and increase fuel consumption twenty times. With its afterburner kicked in, Cutler states, the "relatively fuel-efficient" F-15 fighter torches fuel at the astounding rate of four gallons per second — 14,400 gallons per hour. And as the military opts for bigger, faster, more sophisticated weapons, fuel efficiency continues to plummet
