In an alternate timeline, the Nebula -class was described as being "a lot faster" than a Yellowstone-class runabout. ( DS9: " Second Sight") By 2374, the USS Bonchune was able to pursue and catch the Prometheus-class USS Prometheus, that was traveling at warp 9.9. When fine-tuned, the warp drive could be pushed to warp 9.6. ( TNG: " Redemption II") By 2370, the theoretical maximum speed for the warp drive of Nebula-class starships, including the USS Prometheus, was warp 9.5. In 2368, the maximum warp for the class was warp 9.3. Additionally, the starboard power coupling was located adjacent to decks ten through twelve. The engines of a Nebula-class needed to operate with a mixture above ninety percent in order to successfully leave orbit of a planet.

He added that "modern" Starfleet vessel impulse engines operated on little conventional rocket thrust anyways, being more of a sub-warp subspace drive. In an entry on Doug Drexler's weblog, Rick Sternbach indicated that he envisioned the ship's impulse drives as being hidden behind baffles to scatter their signature for stealth reasons. ( TNG: " The Wounded", etc.)Ī careful inspection of the Nebula -class model reveals that it has no visible impulse engines. The Nebula-class shared a similar design lineage with its larger Galaxy-class counterpart, notably its primary and secondary hulls and warp nacelles. The Nebula-class was still in Starfleet service by 2378. ( DS9: " The Changing Face of Evil", " What You Leave Behind") A Nebula-class starship, the USS Farragut, was one of three ships sent to transport the crew of the USS Enterprise off Veridian III after the saucer section crash landed due to a battle with a Klingon vessel. ( 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. 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: " Second Sight", " Explorers" TNG: " Brothers" set artwork TNG: " Sarek", " The Game") The mission profile of the Nebula-class varied from performing various scientific and exploratory roles to conducting patrol and transport duties.

( TNG: " The Wounded", " Redemption II" DS9: " Second Sight", dedication plaques) Vessels including the USS Phoenix, the USS Prometheus, and the USS Sutherland were constructed at this time at both the 40 Eridani A Starfleet Construction Yards (the first two ships) and the San Francisco Fleet Yards. 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.
