Guardian Class
The Guardian-class spacedock is currently the largest class of space station in operation by the United Federation of Planets. Combining successful design features from both the Spacedock-class family and the Regula-class family, this massive station has multiple large docking facilities, the capability to handle modular additions, and some of the most potent defensive armaments in Starfleet service. These stations are still rare, with the first one not coming online until 2396.
Mission Parameters
Like all spacedock-type stations, the Guardian-class is a large, multi-purpose station with the ability to manage the logistics needs of an entire sector. They are equipped for starship construction, repair, and resupply, large scale trade and cargo operations, scientific inquiry command and control functions, and are potent defensive platforms, all while serving as a home to tens of thousands of residents.
This class's most distinguishing feature is the presence of a large docking bay on the top of the station, drawn from the Spacedock-class, as well as a smaller secondary docking bay on the bottom of the station, drawn from the Regula family. The upper docking bay has large space doors and is capable of admitting even the largest of starships, while the lower docking bay is open to space to allow for quick turn-arounds of visiting cargo vessels. This split's the station's docking operations much more effectively than the single large docking bay present on the Spacedock class, and allows the upper docking bay to devote more space to construction and maintenance facilities.
