Star Base 6
Star Base 6 was a Federation star base, the nearest one located to the planet Gravesworld.
Historical significance
In 2268, the USS Intrepid, NCC-1631 worked in conjunction with Star Base 6 in conducting a mission to investigate the loss of contact with solar system Gamma 7A in Sector 39J. On stardate 4307.1, Star Base 6 lost contact with the Intrepid and a rescue priority was issued to the USS Enterprise, NCC-1701, which was already en route.
Later that year, the Enterprise traveled to this base where it rendezvoused with the USS Lexington, NCC-1709, and was ordered to be refitted with the M-5 computer. All but twenty of the Enterprise's crew were offloaded to this base, where they were kept in a security holding area, while the ship proceeded to participate in a battle simulation.
