The following is a list of unnamed Federation starships in service during the 23rd century.

By assignment Edit

Coleman's starship Edit

Doctor Arthur Coleman was removed as chief medical officer of this ship for "administrative incompetence" and "flagrant medical blunders". In 2269, Leonard McCoy mentioned this fact to "James T. Kirk" while explaining why he felt "Janice Lester" should not have been placed in Coleman's care rather than his. (TOS: "Turnabout Intruder")

This starship was only mentioned in dialogue.

Charlie's transport Edit

Charlie's transport was a ship that suffered a crash landing on the planet Thasus circa 2252. Losing his parents in the crash, Charles Evans was the lone survivor. It was equipped with microtapes and enough food concentrates to last approximately a year, according to Spock.

When Doctor Leonard McCoy expressed doubt in 2266 that the ship's food supplies would have lasted fourteen years, Charlie claimed to have found food "growing around" on the planet`s surface after the ship's supply was exhausted, and that he learned to talk by listening and responding to the ship's memory banks. (TOS: "Charlie X")

This transport was only mentioned in dialogue.

Garth's starship Edit

Fleet Captain Garth of Izar was a starship commanding officer in the mid 23rd century. His starship was involved in many important historical actions. (TOS: "Whom Gods Destroy")

Garth's ship (or ships) were never identified by name or design, but it was referenced that he was in command of some type of vessel on multiple occasions. It is not known how many ships he commanded, as he might have commanded a different vessel in each event.

Garth commanded his vessel to victory at Axanar some time prior to James Kirk's completion of Starfleet Academy. While Garth was a military hero at Axanar, Cadet Kirk was given the Palm Leaf of Axanar Peace Mission.

The Four Years War, an RPG reference book published by FASA, identified Garth's ship at this time as the USS Xenophon (β), a Marklin-class (β) destroyer.

Garth ordered his starship's crew to destroy a sovereign, populated planet. They refused his order, and he was institutionalized at Elba II.

Since this event would seem to be more than a decade after Axanar, it is not known if Garth would have been on a different ship at this point. The novel Garth of Izar identified Garth's ship as the USS Heisenberg, and states the ship's first and second officer were vaporized with a phaser by Garth before he was subdued.

Quartet of starships Edit

Four Starfleet starships were either docked or docking to an orbiting dock station when there was a briefing about the activities of the USS Discovery on board the station in the Federation-Klingon War of 2256. (DIS: "Choose Your Pain")

Winston's trading vesselEdit

By mission Edit

Altair VI attendees Edit

These two starships, along with the USS Enterprise, were expected to attend the inauguration ceremony for Altair VI's new president in 2267. (TOS: "Amok Time")

According to the 29 May 1967 draft of the script, these two vessels were identified as the Excalibur and Endeavor.

Beta Capricus expedition Edit

In 2210, an unnamed starship participated in mission to Beta Capricus, under the command of Harry Kim's Uncle Jack. The long range deep-space exploration vessel was designed to be operated by a single pilot while the rest of the crew was held in stasis.

After departing Earth's orbit their starship took six months to reach its destination. Unfortunately, unbeknownst to Earth researchers, there was no star at Beta Capricus. What was believed to be a star was in fact just an electromagnetic echo of a distant galaxy.

Left with little alternative, Jack was forced to turn the ship around and make the trip all the way back to Earth, deciding not to wake the crew. Upon the vessel's return from its year long voyage, the wakened disgruntled crew was eager to learn why they had not yet left orbit. (VOY: "11:59")

This starhip was only mentioned in dialogue.

Corvan II relief Edit

In 2256, this unspecified starship was 84 hours away from Corvan II at the time the colony was attacked by Klingon Bird-of-Preys. (DIS: "The Butcher's Knife Cares Not for the Lamb's Cry")

This starship was only mentioned in dialogue.

Gamma Trianguli VI scoutEdit

In 2267, an unidentified scout reported unusual sensor readings from Gamma Trianguli VI to Starfleet Command. In response to the finding, Command ordered the USS Enterprise to the planet. (TOS: "The Apple")

This scout was only mentioned in dialogue.

Ingraham B vessel Edit

Eight months prior to the USS Enterprise's stopover at Deneva colony, the infestation with flying parasites began when a vessel from Ingraham B was diverted to Deneva by the crew of the ship, who were under the control of the parasites at the time. (TOS: "Operation -- Annihilate!")

This starship was only mentioned in dialogue.

Yorktown docked starships Edit

In the alternate reality of 2263, two starships were present at Starbase Yorktown shipyard when the USS Enterprise-A was being constructed. The first was entering the shipyard, while the second was docked. (Star Trek Beyond)

The first ship was briefly seen in the montage, passing from left to right behind the Enterprise-A.
The second ship was briefly seen in the background, behind the Enterprise-A.
