History and specifications
A station of this designation remained active after the Burn and into the 32nd century. By the 3180s decade, its location was marked on a holographic star chart in the command center of the Federation Headquarters space station. In 3189, Starbase 21 was on display on that star chart during a mission briefing held by Fleet Admiral Charles Vance. (DSC episode: "Scavengers")
