Aircraft having a controllable center of gravity and method of use

An aircraft having a controllable center of gravity, the aircraft comprising:

• a blended wing body;
• a first tank located within the blended wing body and configured to store a first portion of a non-consumable ballast, wherein the non-consumable ballast comprises a slurry;
• a second tank configured to store a second portion of the non-consumable ballast, located within the blended wing body and disposed substantially aft of the first tank;
• at least a pipe configured to provide fluidic communication between the first tank and the second tank;
• at least a pump configured to pump the non-consumable ballast bidirectionally between the first tank and the second tank by way of the at least a pipe;
• and
• a controller in communication with the at least a pump and configured to control a longitudinal ballast ratio of the first portion of the non-consumable ballast relative the second portion of the non-consumable ballast and affect an aircraft center of gravity.
