Shape

A wide fuselage was selected for the DragonFly; which is combined to a lifting body configuration for shorter take-offs and landings. The cross-sectional profile of the aircraft is close to that of the SR71, minus the exposed engines. The SR-71 overall dark grayish look remains.

The design goal for empty weight is around 75MT. The weight of the set of engines should not exceed 10MT. The total weight of carbon/carbide paneling should not exceed 15MT. The weight of the titanium airframe should not exceed 15MT, and 15MT for two fuel tanks.
