- The Enterprise Evolution Plans have the registry of Archon as NCC-1370 and as the lead ship of the Archon-class starships.
Archon went missing around 2167 and was presumed destroyed. It was eventually discovered that Archon was destroyed at Beta III after being pulled from orbit by the Landru computer and crashed on the planet. (TOS: "The Return of the Archons")
In different realities, Archon has had various different designations.
Archon, under the command of Captain Uttan Narsu, was in Earth Starfleet service during the Earth-Romulan War. Along with the starships Essex, Carolina and Intrepid, it participated in war games exercises against Enterprise (NX-01) in 2156. (ENT novel: The Romulan War: Beneath the Raptor's Wing)
