Deep Space Nine is a fictional space station, the eponymous primary setting of the American science fiction television series Star Trek: Deep Space Nine which aired from 1993 to 1999. It serves as a base for the exploration of the Gamma Quadrant via the Bajoran wormhole and is a hub of trade and travel for the sector's denizens. It is run by a joint crew of Starfleet and Bajoran officers and it is the home port of a number of Starfleet runabouts, as well as the starship USS Defiant.

Runabouts are a fictional class of small, multi-purpose starships appearing in the Star Trek science-fiction franchise, primarily the television series Star Trek: Deep Space Nine, which aired on syndicated television between 1993 and 1999. They served as a means of transport for the crew of the fictional space station Deep Space Nine, in the early seasons of the series enabling storylines taking place away from the station.
