The USS Callisto (NCC-80109) was a Federation starship, a Luna-class vessel in Starfleet service in the 24th and 25th centuries. This ship was launched near the end of the 2370s decade. (TTN novel: Taking Wing - "Luna Class Concept Notes"; TTN novel: Sword of Damocles - "Titan Foldout")


24th century[]

In March 2384, the Callisto, along with the USS Nogura, was the closest Starfleet ship to the Pyrithia star system. Both ships were ordered to Pyrithia IV to seize control of a secret Breen base, its assets and personnel. Security personnel from the Callisto stormed the base with their counterparts from the Nogura and the USS Enterprise-E. (TNG - Cold Equations novel: Silent Weapons)

The Delta Quadrant[]

In the early 25th century, the Callisto was on deep space mission on the edge of the Delta Quadrant, 30,000 light-years from Sol. By that time, three years were left in its mission to the Delta Quadrant. Via a class B itinerant pulsar, the Starfleet Communications Research Center was able to send a datastream to the ship every four days. In 2409, the Callisto discovered an artificial construct larger than an entire star system. Reginald Barclay of the Communications Research Center theorized it was a Dyson sphere. In a message sent to Fleet Admiral Jorel Quinn, Captain Vaughn Alexander of the SCRC recommended to dispatch the Callisto to investigate the potential sphere. (Star Trek Online official website: Season 8 Dev Blog #1)

In the year 2410, Federation researcher Seven of Nine was aboard the Callisto when it was attacked by the automated defense system of a Federation outpost in the Yontasa sector. The Callisto was destroyed but Seven succeeded in turning off the automated defenses and transported the survivors of the Callisto's complement of 350 to the station. Soon after, an Alpha Quadrant Alliance starship arrived in response to a distress call and defended the outpost against attacking Voth ships. The AQA starship took the Callisto's and outpost's crew aboard and proceeded to the Turei homeworld, which was under attack by the Vaadwaur Supremacy. When the Turei were saved by the AQA and the Voth, USS Voyager arrived in the system and took over Callisto's survivors. Seven permanently joined the crew of Voyager at Rear Admiral Tuvok's request.
