The USS Horatio (NCC-10532) was an Ambassador-class heavy cruiser in service to Starfleet in the 24th century. From the 2340s to 2364, the Horatio was under the command of Captain Walker Keel. (TNG episode: "Conspiracy"; ST reference: Star Trek Encyclopedia; Decipher RPG modules: Starfleet Operations Manual, Starships)
In 2344, the Horatio was at Utopia Planitia Fleet Yards undergoing a refit. (TOS novel: Vulcan's Heart)
In 2348, the Horatio returned to Earth so that Keel could attend the wedding of Jack Crusher and Beverly Howard. The marriage was made possible by Keel after he introduced the two to each other. (TNG novel: Death in Winter)
In 2364, the Horatio rendezvoused with the USS Enterprise-D, the USS Renegade, and the USS Thomas Paine in orbit of Dytallix B so that Keel could discuss the possibility of a conspiracy in Starfleet Command with Captains Jean-Luc Picard, Tryla Scott and Rixx. Following this meeting, the Horatio was mysteriously destroyed in Sector 63. Starfleet Command believed the ship imploded. (TNG episode: "Conspiracy")
