Captains: Robert April (James Doohan [voice], Adrian Holmes), Christopher Pike (Jeffrey Hunter, Sean Kenney, Anson Mount), James T. Kirk (William Shatner), Willard Decker (Stephen Collins), Spock (Leonard Nimoy). The Federation's first Enterprise is the main setting of the original Star Trek series (1966–1969) and Star Trek: The Animated Series (1973–74). Having undergone an extensive rebuilding and refitting, Enterprise then appears in Star Trek: The Motion Picture (1979), Star Trek II: The Wrath of Khan (1982), and Star Trek III: The Search for Spock (1984) in which the starship is destroyed by its crew to escape capture. Depictions of the Enterprise made occasional appearances in later Star Trek series, before being reintroduced as the main setting of the prequel Star Trek: Strange New Worlds, portraying the ship's missions in the decade prior to The Original Series. Details of the ship's appearance differed in the various series and films in which it appears. In the 1965 pilot episode "The Cage", whose footage was reused for a flashback to Captain Pike's command in the episode "The Menagerie" (1966), the ship's bridge featured a transparent dome ceiling that was absent for the rest of the Original Series. A significantly redesigned version of Captain Pike's Enterprise appears in Star Trek: Discoverys second season, set several years after the events of "The Cage". The new design for the Enterprise, which more closely matches the aesthetic of Discovery, debuted in 2018 at the conclusion of the season 1 finale, and would go on to become the main setting of the series Strange New Worlds. When the Enterprise was reintroduced in the 1979 film Star Trek: The Motion Picture, the ship had just completed an extensive refit and redesign that included new slimmer warp nacelles, connected to the secondary hull by angled winglike struts. The updated design would be reused later for the Enterprises replacement, an identical starship given the name Enterprise and registry number NCC-1701-A.

Kirk (William Shatner) This ship first appears at the conclusion of Star Trek IV: The Voyage Home (1986) and is the main setting in the subsequent Star Trek movies which use the original crew. The ship is ordered "decommissioned" at the end of Star Trek VI: The Undiscovered Country (1991).
