  • Core constructed of asteroid collapsed on itself via shaped antimatter explosions and coated in a layer of diamond, resulting in a sphere with density nearing 400 g/cc, in order to provide artificial surface gravity of 0.86g, near-identical to gravity of Lorina (TOS Novel: Ex Machina)
• Propelled by fission-based thrusters (TOS: "For the World is Hollow and I Have Touched the Sky"; TOS Novel: Ex Machina)
