History

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...")
