Without specifying exactly which aircraft, this is impossible to say because there are such huge variations.
Most modern fighters carry 1,500 -2,000 gallons of fuel.
Internal the F-15 holds about 13,455 lbs of fuel which is (depending what weight number you use) about 1979 US gallons of fuel. External fuel on three hard points can handle up to 3 x 600 US gallons of fuel plus F-15C and E's carry that with what are called conformal tanks. They hold 750 US gallons of fuel. So, say a F-15C on a long transfer trip to the middle east will carry, 1979 gallons with three hard points drop tanks with a total fuel of 3779 gallons of fuel
29,026 gallons
The volume is pi*radius2*depth of fuel = 22.6 cubic feet = 140.9 Imperial gallons, approx.
16,900 gallons.
Assuming you mean gallons of fuel, it holds 17.1 US gallons of fuel.
Assuming you are asking about gallons of fuel, it holds 17 gallons of fuel.
