The Presidio class was a type of Federation command battlecruiser starship in Starfleet service in the early 25th century. The Presidio-class was one of three Starfleet command battlecruisers and had a counterpart in the Klingon Defense Force and the Romulan Republican Force, respectively. All of the command battlecruisers were tier 6 starships and required a commanding officer ranked vice admiral or higher. (STO video game: Delta Rising) The Presidio-class appears to be named after the Presidio, the section of the Earth city San Francisco where Starfleet Academy is located.
