The Conformal Fuel Tanks (CFTs) are an addon available for the F/A-26B, applied in the same way its external TGP would be. Like the TGP addon, the CFTs cannot be jettisoned. The CFTs allow the F/A-26B to hold an extra 6400 total liters of fuel for flight. This has the main benefit of being able to greatly increase its maximum flight range without taking up its extra fuel tank ports. This gives the pilot an advantage in armament for super long-range or otherwise long-term missions. On the other hand, this brings about a very heavy penalty to your Thrust to Weight Ratio with greater amounts of fuel being loaded in. This can make maneuvering in short order a great challenge, and may necessitate a fighter escort in missions where hostile fighters and/or interceptors are a threat. Even so, the CFTs can make for a fair addon in roles where maneuvering isn't much of a problem.
