The fuel capacity of an F-15 fighter jet varies depending on the model and specific configuration. The F-15C, for example, has a maximum internal fuel capacity of approximately 17,300 pounds (7,852 kg) distributed across two main fuel tanks in the fuselage and four conformal fuel tanks mounted on the sides of the aircraft. Additionally, the F-15 can be equipped with external fuel tanks, such as drop tanks or conformal fuel tanks, to extend its range.
Range:
The range of an F-15 fighter jet also depends on several factors, including its fuel capacity, mission profile, and flight conditions (e.g., speed, altitude, and weather). With its internal fuel and without external fuel tanks, an F-15C has a combat radius of approximately 500 miles (805 km). With the addition of external fuel tanks, the range of an F-15 can be significantly increased. For instance, with two 600-gallon (2,271-liter) external fuel tanks, the combat radius of an F-15C can be extended to over 1,000 miles (1,609 km).
It's important to note that these figures are approximate and can vary based on specific aircraft configurations and operational requirements.
