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 do increase aerodynamic drag slightly during flight, causing a correspondingly slight decrease in performance, but the pilot is unable to detach and drop them during the flight. 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: Does it sound like a fighter pilot is making a trade-off when choosing CFT's (which presumably have less drag than wing tanks) over drop tanks carried under the wing when going into combat, choosing higher performance with the tanks against the ability to decide when and if to drop weight during a dogfight?
YES.
