Yard 39 was a Federation shipyard, a space station with drydock facility. It was located in the the TL-9139 system in the Tellar sector of the galaxy's Alpha Quadrant. In 2259, the shipyard was abandoned for 150 years due to an environmental hazard in the star system. (STO - Age of Discovery short story: "Utopia Planetia: The Mystery of Yard 39")
History and specifications[]
In 2259, several Starfleet ships operating with Eaves-Beyer warp drives were docked at Yard 39 when a freak eruption flooded the system with baryon radiation. Starfleet abandoned Yard 39 and the starship hulks. Subsequently, the system was deemed too hazardous for travel. A pulsing green cloud expanded from TL-9139, and a navigation clearance zone of 0.5 light-years was established. This also led Starfleet to phase the Eaves-Beyer drive out in favor of the established Cochrane-Archer assembly.
150 years later, in 2410, the eruption was abating, and the system would be visitable a few weeks after the launch of the USS Narendra. The staff of the Utopia Planitia Fleet Yards became interested in recovering the abandoned ship hulks at Yard 39. (STO - Age of Discovery short story: "Utopia Planetia: The Mystery of Yard 39")
Starfleet reclaimed Yard 39, recovered the hulks and returned the phased-out classes to service. Brand-new ship classes were based on the Burnham's War-era designs as well, including the Europa-class. (STO - Age of Discovery short story: "Utopia Planetia: The Mystery of Yard 39", STO video game: Age of Discovery website: "The Stats of the Europa Class!")
Starfleet Command directed considerable resources into the TL-9139 system based facility. Other powers of the Alpha Quadrant Alliance and shipyards contributed to revive further 23rd-century ship classes. This was reported on stardate 87831.2 in an article by the Jayce's Interstellar newsfeed. (STO - Mirror of Discovery short story: "Jayce's Interstellar: Around the Galaxy")
Following the Shattering of the Klingon Empire during the Klingon Civil War of 2411, at some point after stardate 87971.0[1], joint Khitomer Alliance starship development programs with the Klingon Defense Force were halted or canceled. Starfleet refocused on the Yard 39 project to revive starships of the 2250s decade.
The first new ship of this project was the USS Shenzhou, named after Captain Philippa Georgiou's notorious ship of the same name. The Shenzhou entered service in the year 2411. Its design was an evolution of the Walker- and Georgiou-class light exploration cruisers. (STO website: House Shattered: The Legendary Walker Light Battlecruiser)
