For the mirror universe counterpart, see Imperial Starbase 47.

Vanguard was the name given to Starfleet Starbase 47. It was a Watchtower-class station constructed by the Starfleet Corps of Engineers between 2263 and 2265 in the Taurus Reach, a region beyond Federation space, between the Klingon Empire and the Tholian Assembly. It was declared fully operational on stardate 1271.4 under the command of Commodore Diego Reyes. (VAN novel: Harbinger)

In 2266, Vanguard's crewmembers worked in three duty shifts: Alpha shift was from 0700 to 1500 hours, Beta shift from 1500 to 2300 hours, and Gamma shift from 2300 to 0700 hours.

Rear Admiral Heihachiro Nogura assumed command of Vanguard after Reyes' court martial. (VAN novel: Open Secrets)

In 2267, a Klingon fleet under Captain Kutal was immobilized by the Organians as it prepared to assault the station. Later that year, Vanguard suffered damage when attacked by the Shedai Wanderer. (VAN novel: Precipice)


In late 2268, experiments on Mirdonyae Artifacts in Vanguard's secret laboratory, the Vault, drew the attention of the Tholians. Their history with the Shedai imprisoned within the artifacts was enough to provoke them into mustering an armada, consisting of approximately twenty percent of their active combat fleet, and heading to the station to destroy the Shedai before they escaped and enslaved them once more.

Admiral Nogura ordered an evacuation of all civilians and non-essential Starfleet personnel. To that end, he ordered every civilian ship within three days of Vanguard to assist in the evacuation. A small fleet of Starfleet vessels remained to defend the station. The fleet consisted of the USS Buenos Aires, USS Endeavour, USS Panama, USS Sagittarius and, at the last moment, the USS Enterprise.

Despite a valiant defence, Starfleet was outgunned five-to-one, and the Buenos Aires and Panama were destroyed. Vanguard was severely damaged and, after the Tholians ignored Nogura's request for surrender, he ordered the fleet to retreat even though the station had not been fully evacuated. Cut off in the Vault, Lieutenant Ming Xiong activated the self destruct when the vengeful Shedai escaped from their containment. The resulting explosion obliterated Vanguard and wiped out the Shedai, it also destroyed most of what was left of the Tholian armada. Operation Vanguard was officially over. (VAN novel: Storming Heaven)

By 2270, the designation of "Starbase 47" had been transferred to another facility near the Romulan Neutral Zone. (TOS comic: "The Chosen")

By 2343, the designation had been transferred again to a facility near Cardassian space. (TLE novel: The Art of the Impossible)

Docking bays

USS Endeavour leaving docking bay 1

Vanguard had at least 92 docking bays for vessels of varying sizes. The four main bays in the primary hull could accomodate starships up to the size of the Constitution-class, while the others catered for smaller ships and shuttlecraft. Docking Bay 92 was large enough to service Cervantes Quinn's Mancharan starhopper, Rocinante. (VAN novel: Harbinger)

Lower core

The lower core was serviced by four turbolift shafts, and included the secret laboratory, the Vault. Cargo bays were located through levels 44 to 51. (VAN novel: Storming Heaven)
