- Per Ships of the Star Fleet, Saratoga had a registry of NCC-1892 and was a Cyane-class heavy frigate, the spaceframes of which were based on Avenger-class ships. The Star Trek Encyclopedia promulgates an incorrect NCC-1937, despite the registry's being visible in the film.
In the 2280s, Saratoga's commanding officer was Captain Alexander. The ship was patrolling Sector 5 near the Klingon Neutral Zone when it encountered an alien probe whose projected course would have as its destination the Sol system.
After repeated attempts to communicate with the probe, Saratoga's primary power systems were drained and it fell back to reserve power. (Star Trek IV: The Voyage Home)
- Ship Recognition Manual, Volume 4: Starships of the Original Series Era states that the Saratoga was destroyed by the Whale probe.
In 2286, after the ship was repaired, command of the Saratoga was given to Captain Edward Stanfield, upon which he served as its CO until given command of the USS Valkyrie in 2294. Leonin Amorek, a former first officer, was its next commanding officer. (Star Trek: Valkyrie)
