Background information Edit
A study model was eventually built for the original Star Trek Chronology by Greg Jein and later put on a stand with a TNG-era communicator to be put in Sisko's office, where it can be seen in the background in numerous episodes, along with a model of the International Space Station, the Miranda-class USS Saratoga, and the Nebula-class USS Melbourne.
According to the reference books Star Trek Concordance, the Star Trek Encyclopedia, Star Trek Maps and The Worlds of the Federation and the current startrek.com article, this vessel was the starship that visited the planet Sigma Iotia II in 2168, as mentioned in TOS: "A Piece of the Action". In the episode, it was stated that the Horizon came "from the same outfit as" the USS Enterprise, but it was never specified if that "outfit" was Starfleet or the Federation, nor was the prefix USS ever stated.
