Depends how much fuel you put in it
3000 gallons of Jet fuel
Internally, an F-18 jet can hold 14,400lbs of fuel.
the ammount of fuel a fighter jet uses depends on they type of aircraft EG. how many engines, how big they are ect. for example the SR-71A blackbird uses around 3.6 kilalitres of fuel an hour
Most modern fighters carry 1,500 -2,000 gallons of fuel.
An F-16 fighter jet typically has a fuel capacity of around 7,000 pounds (approximately 3,175 kilograms) when using its internal fuel tanks. This can be increased with external fuel tanks, which can add an additional 1,000 to 2,000 pounds of fuel, depending on the configuration. The total fuel capacity allows for a combat radius of around 300 miles (480 kilometers) without refueling, depending on the mission profile.
NATO countries use JP-8, which is a kerosene-based fuel.
Freighter or fighter jet or fuel truck
The F-22 Raptor can hold about 3,050 gallons or 20,333 pounds of JP-8 jet fuel internally.
3.89087654 lb per hr
Most use JP-1 a type of kerosene.
Every fighter jet is different. For the F22 Raptor most of the fuel is used doing high speed maneuvers and flying at supersonic speeds. While on a carrier, the F-22 uses very little fuel due to catapult and flying into the wind to help elevate the fighter jet.
