The USS Equinox was a Nova-class starship, commissioned by Starfleet in 2370 and remained missing, but in service, during the 2370s. During this time, the Equinox was under the command of Captain Rudolph Ransom. Like most Nova-class starships, the Equinox was built for short-term scientific missions, like planetary expeditions. At its launch, the Equinox had a crew of 78. Janeway integrated the remaining five Equinox crew into the Voyager crew. (VOY: "Equinox", "Equinox, Part II")
