The USS Cheiron was a Federation Centaur-class medium cruiser starship in Starfleet service in the 24th century. The Cheiron was in active service around the 2380s decade, and was named for a character of Earth's Greek mythology.
In 2380, the Cheiron was assigned to the independent world of Carrea at the request of the Carreon Science Institute, to investigate solar flares from the system's sun. In March of that year, Federation President Nanietta Bacco used the Cheiron's presence at Carrea to threaten war with that world, following long and fruitless negotiations for a Carreon water reclamation system for Delta IV.
