Starfleet Headquarters
Starfleet Headquarters was the administrative center of Starfleet Command located in California, on Earth. Sharing grounds with Starfleet Academy, it encompassed territory adjacent to the city of San Francisco, on either side of the Golden Gate passage into San Francisco Bay.
The sprawling complex was originally built as the headquarters of the Earth Starfleet in the early 22nd century, on what was previously a portion of Golden Gate National Recreation Area in Marin County, overlooking Horseshoe Bay. After the founding of the United Federation of Planets in 2161, it continued to serve as the command center of the Federation Starfleet. By the 2270s, the headquarters had expanded to the Presidio, an ancient military post on the southern side of the Golden Gate where it included an air tram station. (Star Trek: The Motion Picture)
In 2369, Odo tried to contact Starfleet Headquarters to tell them about the situation on Deep Space 9. However, Major Kira Nerys had ordered all transmissions to the Federation be blocked. (DS9: "Dramatis Personae")
In 2371, Benjamin Sisko was debriefed on the Dominion situation in Starfleet Headquarters for several weeks. Sisko also enjoyed visiting it, hoping to be an Admiral based there one day. (DS9: "The Search, Part I")
Admiral Charlie Whatley contacted Captain Benjamin Sisko from Starfleet Headquarters in 2373. (DS9: "Rapture")
Rear Admiral Bennett, the Judge Advocate General, had an officer at Starfleet Headquarters. He told Richard Bashir to report there in later in 2373, when he arrived on Earth from Deep Space 9. (DS9: "Doctor Bashir, I Presume")
In late 2375, during the Dominion War, Starfleet Headquarters was attacked by the Breen. Buildings were badly damaged, including the historic Golden Gate Bridge, and many people were killed. (DS9: "The Changing Face of Evil", "When It Rains...")
