History and specifications
In 2259, several Starfleet ships operating with Kurtzman-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 lightyears was established. This also led Starfleet to phase the Kurtzman-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. (SS STO (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. (SS STO (Utopia Planetia: The Mystery of Yard 39), 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.
