Starbase 375 was a Starbase 375-type Federation space station that was in service with Starfleet in the late 24th century.


In 2375, the location of Starbase 375 was labeled on a tactical cartography map that was displayed in the wardroom of Deep Space 9. Starbase 375 was located approximately thirty light years from Cardassia Prime, twenty-five light years from Bajor, and fifty-five light years from Ferenginar. (DS9: "When It Rains...", okudagram)

According to the Star Trek: Deep Space Nine Technical Manual, (p. 3), Starbase 375 was located in the Bajor sector. [1]

In 2399, the location of Starbase 375 was labeled in a Federation star chart that was in Fleet Admiral Kirsten Clancy's office at Starfleet Headquarters. The base was in or near Federation space. (PIC: "Maps and Legends")

In 2401, Starfleet Academy cadet Tiffson Modany was assigned to Starbase 375. (PIC: "The Star Gazer")


Following the Second Battle of Deep Space 9 and the subsequent withdrawal of Federation and Klingon forces from Deep Space 9 in late 2373, the USS Defiant, under the command of Captain Benjamin Sisko, was recalled to this starbase for reassignment. Captain Sisko was stationed here as adjutant to Admiral William Ross after Ross relieved him of command of the Defiant. This starbase was also the location of a Jem'Hadar attack ship retrieved by Sisko a year prior from Torga IV. (DS9: "A Time to Stand")

The IKS Rotarran was contacted by the base upon it's arrival there, returning Captain Sisko and his wayward crew following the completion of his mission. (DS9: "Sons and Daughters")

Approximately four months later, Starbase 375 served as gathering point for the Second and Fifth Fleets in preparation for Operation Return, in which combined Federation and Klingon forces managed to retake Deep Space 9. Sisko then returned to his previous post as commander of Deep Space 9. (DS9: "Favor the Bold", "Sacrifice of Angels")

In 2375, Starbase 375 was displayed on a map during a briefing given by Chief Miles O'Brien. (DS9: "When It Rains...")




Background information

The Star Trek: Deep Space Nine Technical Manual (p. 18) included a directory for Starbase 375 that was created, but seen only in the background of Admiral Ross' office, for "Behind the Lines". It listed several Deep Space Nine production staff members as Starbase 375 personnel, including Ronnie Knox, Ed Cooper, Phil Jacobson, Ralph Johnson, Don Lehman, Mickey Welsh, Murphy Wiltz, Steve Gausche, Jack White, Brian Johnson, Edmond Wright, Derek Garth, Bill Gocke, Mark Overton, Todd Overton, Jim Unsinn, Bob Blackman, Carol Kunz, Phyllis Corcoran, Mary Ellen Bosche, Camille Argus, Jerry Bono, Cleo Severy, Russ English, Myles Abney, Michael Westmore, and Valerie Canamar.

According to Star Trek: The Magazine Volume 3, Issue 12, an aeroshuttle, hull #AS-508, was attached to this starbase.

According to Star Trek: Star Charts (p. 47) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"; "The Dominion War: Strategy and Battles, 2373-75"), Starbase 375 was, during the Dominion War, the headquarters for Fifth Fleet.

This starbase was listed, with other spacecraft, under "Assignment" on a PADD used by a Starfleet Academy officer. This PADD is seen in the The Ready Room episode "Mercy".


Starbase 375 was mentioned in numerous novels including Hollow Men, Articles of the Federation, and A Singular Destiny.

In an alternate timeline featured in the Star Trek: Myriad Universes novella A Gutted World, Starbase 375 was destroyed by the Jem'Hadar in 2373.
