The San Francisco Fleet Yards, also known as the San Francisco Naval Yards or San Francisco Yards, was a Federation space station with associated ground facilities operated by shore offices located in Mare Island near San Francisco, a construction support station with Federation shipyards located in orbit of Earth. As well as containing several drydocks, there was also an orbital office complex that acted as a nexus for the yards. (TOS movie: The Motion Picture, STO - Klingon War mission: "Welcome to Earth Spacedock")
Among the Starfleet vessels to be constructed at the yards were the USS Constitution (NCC-1700), USS Enterprise (NCC-1701), USS Eagle (NCC-956), USS Excelsior (NCC-2000), USS Sutherland (NCC-72015), and the USS Enterprise (NCC-1701-E).
In the 2240s, Montgomery Scott was assigned to the San Francisco Fleet Yards, where he served on the construction teams working on four Constitution-class starships, including the Enterprise. (TOS novel: The Galactic Whirlpool)
Captain Robert April was at the orbital drydock section of the facility when the major components of the Enterprise were built and put together. (ST website: StarTrek.com, TAS episode: "The Counter-Clock Incident")
From 2270 to 2273, the Enterprise underwent a thorough refit in one of the yard's drydocks. In 2273, Commander Montgomery Scott used Travel Pod 5 to ferry Admiral James T. Kirk from the orbital office complex to the Enterprise drydock. (TOS movie: The Motion Picture)
