"The propulsion systems located at both the fore and aft sections of the Andromeda craft would be beyond the last Haunebu-type Thule Tachyonator 7c drive. These craft were to have four massive power units, two Tachyonator 11 at the front and two at the rear with four additional large SM-Levitator units located in pairs on the top and bottom of each craft which sat on a series of large underbody skids to support the massive weight."
