Starbase
From Star Trek : Freedom's Wiki
A starbase is a facility where starships are maintained and resupplied, and crews can relax. A starbase can be a research station, a military base, a place for interstellar trade or a seat of administration. Some starbases are also involved in the construction of starships. Starbases offer various services to vehicles, from medical facilities to full-fledged spacedocks capable of refitting a starship.
Starbases can be partially or completely located on a planet surface, or be limited to strictly spaceborne installations. Some are a combination of a ground-based facility with orbital components.
The two starbases attached to the 52nd Fleet are Starbase Geneva and Spacedock Phoenix.
