Now they need tankers or a friendly base close in..

Low-drag conformal fuel tanks (CFTs) were developed for the F-15C and D models. They can be attached to the sides of the engine air intake trunks under each wing and are designed to the same load factors and airspeed limits as the basic aircraft. However, they degrade performance by increasing drag and cannot be jettisoned in-flight (unlike conventional external tanks). Each conformal fuel tank can hold 750 U.S. gallons (2,840 L) of fuel.[23] These tanks increase range thus reducing the need for in-flight refueling.
The American CFTs were also provided to Israel and Saudi Arabia but only Israel uses them (as needed) on their entire fleet
