A list of unnamed Federation starships of the Nebula-class.

By yearEdit

Wolf 359 starship Edit

Sisko leaves the Saratoga

Battle damaged, Nebula-class starship adrift in space

USS Melbourne wreckage, BoBW

The Nebula-class wreck on fire

This Nebula-class starship was destroyed in the Battle of Wolf 359. The wreck of this ship was adrift in space near the Borg cube when the USS Saratoga was destroyed. (DS9: "Emissary") The wreck was on fire by the time the USS Enterprise-D arrived at the site of the battle. (TNG: "The Best of Both Worlds, Part II")

While illegible in both episodes, this starship model was labeled as the USS Melbourne (NCC-62043). [1] An Excelsior-class starship was also named USS Melbourne in the "Emissary". This ship is listed as unnamed, because Memory Alpha considers the name of this ship has been retconned. See USS Melbourne for more information about the model and the naming issue.
According to the short story "Trust Yourself When All Men Doubt You" in The Sky's the Limit, this Nebula-class Melbourne was constructed to replace the other Excelsior-class Melbourne. The Star Trek Encyclopedia, however, doesn't mention this Nebula-class Melbourne, because it was not the intention that there would have been two different ships with the same name.

Qualor II hulk Edit

Nebula at Qualor II

The hulk of an unnamed Nebula-class starship

In 2368, the hulk of this Nebula-class starship was stored at Surplus Depot Z15 in orbit of Qualor II. (TNG: "Unification I")

Like the ship above, this was a reuse of the model labeled as the USS Melbourne.
The footage of this vessel in "Unification I" was a reuse of the footage from the Wolf 359 debris field from "The Best of Both Worlds, Part II", though the damaged sections of the hull were clearly on fire in the "Best of Both Worlds, Part II" version.

Pursuit vessel Edit

Nebula class, non sequitur

An unnamed Nebula-class chases the USS Yellowstone

In 2371 of an alternate timeline this Nebula-class starship pursued the USS Yellowstone runabout after it was stolen from spacedock by Harry Kim and Tom Paris.

Initially the ship was disabled as it passed through a cloud of tetryon plasma, but later caught up with the Yellowstone and subsequently damaged the runabout's warp drive, causing the runabout's destruction. (VOY: "Non Sequitur")

Though from an alternate timeline, this ship most likely existed in the normal timeline.

Alternate timeline Edit

Nebula class The Visitor

Docked at Deep Space 9

In late-2372 of an alternate timeline this Nebula-class starship docked at Deep Space 9's upper pylon, when Starfleet decided to leave DS9 and the station was taken over by the Klingons. (DS9: "The Visitor")

Battle of Sector 001 Edit

Nebula class, first contact

An unnamed Nebula-class starship attacking the Borg

In 2373, this Nebula-class starship fought against the Borg in the Battle of Sector 001.

It joined in the assault on the Borg cube, led by the USS Enterprise-E, by firing several photon torpedoes at the coordinates defined by Captain Jean-Luc Picard. (Star Trek: First Contact)

Although not identified visually, it is possible that this ship is the otherwise-mentioned USS Lexington, which was referenced in comm chatter during the engagement.
On the other hand, it is concurrently possible that this ship was the USS Endeavour (NCC-71805), as per the Star Trek Encyclopedia (3rd ed, p. 135). In a preliminary script draft for the film, dated 29 September 1995, an Endeavor was explicitly named as one of the starships engaged in the battle in scenes 10 , "PICARD: Signal the Endeavor to fall back. We'll cover them.", and 11, "The Endeavor moves off as the Borg FIRE at the Enterprise and BLASTS the saucer section." These references did not make it into the final cut, leaving the one Nebula-class vessel actually seen, unnamed. Some prints of Star Trek: First Contact do not include shots of this vessel.
This appearance marked the last time that use was made of the physical studio model as a production asset. With the exception of the USS Enterprise-E, all other Federation starships in the sequence where executed as CGI models. For further information on the model, see Nebula-class model.

Earth transport Edit


Transport docked at Deep Space 9

Later in 2373, this Nebula-class starship served as a transport from Deep Space 9 to Earth.

Among the passengers aboard this vessel were Lewis Zimmerman and Amsha and Richard Bashir. (DS9: "Doctor Bashir, I Presume")

This unidentified vessel reused footage of the USS Prometheus from "Second Sight", still being the physical studio model, and was referenced in the script simply as "a Federation transport ship."

Operation Return Edit

USS Defiant, Yeager, Excelsior and Nebula at DS9

A Nebula-class starship at Deep Space 9

In 2374, this Nebula-class starship was at Deep Space 9 following Operation Return. (DS9: "Sacrifice of Angels")

Second Battle of Chin'toka Edit

Nebula class at Chin'toka, 2375

Preparing for battle

In 2375, this Nebula-class starship was one of two that participated in the second Battle of Chin'toka. Both were destroyed during the battle by the Breen's devastating new energy dampening weapon. (DS9: "The Changing Face of Evil")

This and the subsequent appearances are reuses of the CGI model of the Nebula-class. That model had made its debut in the earlier Star Trek: Voyager season four episode "Message in a Bottle" and is identifiable as such for its oval shaped navigational deflector dish housing.

Battle of Cardassia aftermath Edit

Nebula class, What You Leave Behind

A Nebula-class ship waits near Cardassia Prime

This Nebula-class starship fought at the Battle of Cardassia. Following the battle, it waited with other Federation, Romulan, Klingon, and Cardassian ships to launch an offensive against the Dominion forces on and in orbit of Cardassia Prime. (DS9: "What You Leave Behind")
