The most expansive of the ten spaceports located on Bonadan, Spaceport Southeast II also held the distinction of being a key installation within the Corporate Sector. This spaceport's footprint eclipsed the size of many urban centers, yet its infrastructure largely remained at ground level. Within its boundaries were extensive shipbuilding and repair facilities, docking bays suitable for large freighters and barges, a central command post for the Espo, the Authority Merchant Marine academy, and the main office for the postal service. Furthermore, it included passenger stations, repair shops, ground transportation hubs, storage facilities, and accommodations and leisure areas designed for the thousands of Humans and aliens who either resided there or were simply in transit.
