Name Registry Status Notes
USS Constellation NCC-1017 [5] on screen Destroyed in "The Doomsday Machine" TOS. Commanded by Commodore Matthew Decker. The ship's registry was created in an AMT Enterprise model kitbash by rearranging its decals' 1701 registry.
USS Constitution NCC-1700 freeze frame Likely the class ship. Recent technical manuals date its launch to 2244. Its registry appears on a wall display in "Court Martial" TOS. Both Joseph and Jein make this the Constitution. [6] [7]
USS Defiant NCC-1764 [8] on screen Disappears into a rift in space in "The Tholian Web" TOS. In the mirror universe, it reappears 100 years in the past in "In a Mirror, Darkly" ENT.
USS Eagle NCC-956 [9] [10] freeze frame
USS Endeavour NCC-1895 [9] [11] freeze frame
USS Enterprise NCC-1701 [12] on screen Her celebrated five-year mission under James T. Kirk forms the basis of the original series. Recent technical manuals date its launch to 2245. Refitted before the first film and destroyed in the third, when Kirk carries out a self-destruct to avoid her capture by Klingons.
ISS Enterprise NCC-1701 [13] on screen The Imperial Star Ship Enterprise, part of the mirror universe, is seen in the original series episode "Mirror, Mirror" under James T. Kirk, who took command after killing former captain Christopher Pike.
USS Enterprise NCC-1701-A [14] on screen The Constitution class' second Enterprise, which noncanon sources often cite as a renaming of either Yorktown or Ti-Ho -- the latter according to Mr Scott's Guide to the Enterprise. [4] The crew of Enterprise A under Kirk are ordered home for decommissioning following the Khitomer Conference in Star Trek VI: The Undiscovered Country. Kirk's final log entry flags this as the final Enterprise cruise under his command.
USS Essex [15] NCC-1697 [7] noncanon
USS Excalibur [16] NCC-1664 [7] on screen Destroyed in "The Ultimate Computer". (The registry wasn't seen in the original episode but appeared in the remastered version.)
USS Exeter NCC-1672 [17] on screen Commanded by Capt Ronald Tracey. Found in orbit around Omega IV with a dead crew ("The Omega Glory" TOS). Exeter's later adventures figure in a series of fan-made shorts in Starship Exeter. (The registry wasn't seen in the original episode but appeared in the remastered version.)
USS Farragut NCC-1647 presumed Constitution class; registry noncanon Commanded by Capt Garrovick; Kirk's first starship post. See "Obsession" TOS. Farragut's later adventures appear in two fan shorts as Starship Farragut. Trek Encyclopedia puts it in the Constitution class though it wasn't seen on screen, and provides this registry. Jein uses this, but not from the Court Martial list. [4]
USS Hood [16] NCC-1703 [7] on screen Damaged in "The Ultimate Computer". (The registry wasn't seen in the original episode but appeared in the remastered version.)
USS Intrepid NCC-1631 [18] on screen All-Vulcan crew. Destroyed in "The Immunity Syndrome". Trek Encyclopedia put it in the Constitution class though it wasn't seen on screen during the series' original run. Registry from Jein's list in the Encyclopedia gives NCC-1831. (Earlier versions of his list give this as NCC-1631. [4] )
USS Lexington [16] NCC-1709 [7] on screen Damaged in "The Ultimate Computer". Commanded by Commodore Robert Wesley.
USS Potemkin [16] NCC-1657 [7] [19] registry noncanon Damaged in "The Ultimate Computer".
USS Republic NCC-1371 [7] presumed Constitution class; registry canon Kirk served aboard her early in his career. Trek Encyclopedia puts it in the Constitution class though it wasn't seen on screen. The registry was given however. [4]
USS Yorktown NCC-1717 on screen Disabled by an alien probe in Star Trek IV: The Voyage Home; registry in debate. Though Gene Roddenberry, as reported in the Trek Encyclopedia and next-gen Tech Manual, held that Yorktown was rechristened NCC-1701A Enterprise following the Probe crisis of the first film, Mr Scott's Guide said Enterprise A was a rechristening of the new Constitution refit USS Ti-Ho, in tribute to Kirk and crew for saving Earth in the fourth film. (Debate continues.)
Although NCC-1710 USS Kongo is listed on a computer readout in Star Trek VI: The Undiscovered Country, and the original Tech Manual contains the same registry, the ship isn't listed in the 1999 Encyclopedia -- and Jein's 1975 essay proposed NCC-1732. (His original list also offers NCC-1868 Hornet, 1866 Lafayette, 1865 Tashik-Sotra and 1623 Valiant).
