Drawing on their seminal research on combining natural defense forms with historical combat tactics, the Dai Nippon/Skunk Works created several prototypes before accepting the ideal form of their new Turtle Armored Personnel Carrier (APC). The Turtle employs the same electromotive systems as the Mammoth: independent high-torque HTSC (High Temperature Super Conductor, a material widely used in the Mammoth's systems) electromagnetic motors with dual Mil-Spec CVJF (Combat Vehicle Jet Fuel) ducted turbine generators as the main power source.
