Starfleet Command (Earth)

From Memory Alpha, the free Star Trek reference.

Earth Starfleet Command (also known as SFC) was the headquarters of the Earth Starfleet in the mid 22nd century. It was located in the city of San Francisco on Earth, and was the precursor to the modern Starfleet Command of the Federation.

In 2151, Enterprise captain Jonathan Archer met with Admiral Maxwell Forrest, Admiral Daniel Leonard, Commander Williams, and other human and Vulcan officials at Starfleet Command to decide how to proceed with delivering the wounded Klingon Klaang back to Qo'noS. (ENT: "Broken Bow")

In 2152, Archer was forced to return to Starfleet Command in order to decide how to proceed after Enterprise apparently destroyed the Paraagan II mining colony. (ENT: "Shockwave")

In March 2153, Forrest and Williams used Starfleet Command to co-ordinate the response to the crisis caused by re-activated Borg drones. (ENT: "Regeneration")

Later that month, Enterprise was recalled after the Xindi attack on Earth, and Archer went to Starfleet Command to discuss the attack, plan a response, and gain clearance to search for the Xindi superweapon. (ENT: "The Expanse")

After destroying the Xindi superweapon in February 2154, Archer was debriefed by Forrest, Soval, and Williams about his actions in the Delphic Expanse at Starfleet Command. (ENT: "Home")

During shore leave later that year, Archer visited Starfleet Command again. (ENT: "Affliction")

Starfleet Command was also host to the conference Nathan Samuels conducted to form the Coalition of Planets. The xenophobic organization Terra Prime planned to destroy the complex with a blast from the hijacked verteron array on Mars. The leader of Terra Prime, John Frederick Paxton, managed to fire the array after Archer, Malcolm Reed, Travis Mayweather, and Phlox launched a raid. However, thanks to sabotage by Enterprise chief engineer Charles Tucker III, the blast was redirected into San Francisco Bay. After the crisis passed, the conference resumed. (ENT: "Demons", "Terra Prime")

After the signing of the Federation Charter on May 8, 2161, it could be assumed that Earth Starfleet Command was either dissolved, absorbed into, or became the modern incarnation of Starfleet Command that regulates the Federation Starfleet.
