Construction of the Nebula-class was spearheaded under the authority of the Yoyodyne Division, and ranged in construction dates from as early as 2363 to as late as 2367. Vessels including USS Phoenix and USS Sutherland where constructed at this time at both the 40 Eridani A Starfleet Construction Yards and later the San Francisco Fleet Yards orbiting Earth. (TNG: "The Wounded", "Redemption II" dedication plaques)

The mission profile of the Nebula-class varied from performing various scientific roles to conducting patrol and transport duties. (DS9: "Second Sight", "Explorers"; TNG: "Brothers" set artwork; TNG: "Sarek", "The Game")

The Nebula-class was present in several major Federation engagements against the Borg, including the Battle of Wolf 359 and the Battle of Sector 001. (DS9: "Emissary"; Star Trek: First Contact) They were also present in numerous Dominion War battles, including the Second Battle of Chin'toka and Battle of Cardassia. (DS9: "The Changing Face of Evil", "What You Leave Behind")

Nebula-class starships were also shown as models on several occasions such as in Deep Space 9's classroom. (DS9: "The Nagus")

Technical Data


The Nebula-class shared a similar design lineage with its slightly larger Galaxy-class counterpart.

The Nebula-class was composed of two hull sections; the saucer-shaped primary hull mounted atop the secondary hull, with two warp nacelles mounted on either side of the secondary hull, directly below the primary hull. (TNG: "The Wounded", etc.)

Atop the primary hull was a superstructure which could support a variety of modules, such as the inclusion of a triangular platform, fitted with torpedo launchers, an oval platform, or additional warp nacelles. (TNG: "Redemption II", "The Wounded", "Future Imperfect")

By 2375, the Nebula-class was reconfigured slightly to include more of a Galaxy-class style secondary hull and deflector dish. (DS9: "The Changing Face of Evil")

Defensive systems

The Nebula-class was equipped with multiple phaser banks, located at various points along both hulls, as well as multiple torpedo launchers. The Nebula-class had a maximum effective weapons range exceeding 300,000 kilometers. (TNG: "The Wounded")

The typical offensive arsenal of the Nebula-class included a torpedo launcher located on the secondary hull above the deflector dish, and on some variants, a torpedo launcher located on the superstructure located above the primary hull. (Star Trek: First Contact; TNG: "Redemption II") Phaser positions included the forward-most part of the primary hull, and on the secondary hull, below the deflector dish. (VOY: "Non Sequitur", "Message in a Bottle", "Endgame"; DS9: "Emissary")

While considered more than a match for a Cardassian supply ship, the Nebula-class was also capable of successfully withstanding a direct hit from a Cardassian warship as a result of an unshielded attack. (TNG: "The Wounded") They were, however, unable to single-handedly withstand an assault from wing of Cardassian destroyers. (DS9: "Waltz")

Some Nebula-class starships, including the Phoenix used a "high-energy sensor sweep" that cycled every 5.5 minutes. Between each of those cycles, a "window" of 1/50th of a second would open, requiring the ship's shields to be realigned. (TNG: "The Wounded")

Propulsion systems

The propulsion systems for the Nebula-class were constructed under the authority of Yoyodyne Propulsion Systems. (TNG: "Redemption II" dedication plaque)

The engines of a Nebula-class need to operate with a mixture above ninety percent in order to successfully leave orbit of a planet. Additionally, the starboard power coupling was located adjacent to decks ten through twelve. (TNG: "Redemption II")

In 2370, the theoretical maximum speed for the warp drive of Nebula-class starships, including the USS Prometheus was warp 9.5. When fine-tuned, the warp drive could be pushed to warp 9.6. (DS9: "Second Sight") By 2374, the USS Bonchune was able to pursue and catch the USS Prometheus, which was traveling at warp 9.9. (VOY: "Message in a Bottle") In an alternate timeline, the Nebula-class was described as being "a lot faster" than a Yellowstone-class runabout. (VOY: "Non Sequitur")

Auxiliary craft

Nebula-class starships were equipped with a variety of auxiliary craft, including the type 6 and type 7 shuttlecraft, as well as the smaller type 15 shuttlepod, and other large shuttlecraft. (DS9: "Waltz", "Wrongs Darker Than Death or Night", "Tears of the Prophets", "Second Sight"; Star Trek Generations)
