text_A: 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 intakes under each wing and are designed to the same load factors and airspeed limits as the basic aircraft. These tanks slightly degrade performance by increasing aerodynamic drag but can be jettisoned in-flight, regardless of their load. However, they cause less drag than conventional external tanks. Each conformal tank can hold 750 U.S. gallons (2,840 l) of fuel. These CFTs increase range and reduce the need for in-flight refueling. All external stations for munitions remain available with the tanks in use. Moreover, Sparrow or AMRAAM missiles can be attached to the corners of the CFTs. The 57 FIS based at Keflavik NAS, Iceland, was the only C-model squadron to use CFTs on a regular basis due to its extended operations over the North Atlantic. With the closure of the 57 FIS, the F-15E is the only variant to carry them on a routine basis. CFTs have also been sold to Israel and Saudi Arabia.
text_B: Would the common saying among pilots, that the only time you can have too much fuel is when you're on fire, still hold for someone who was flying in combat using CFTs, but wanting to detach those same tanks in order to move with more speed and agility in an imminent dog fight?
NO.
