Ships commissioned Edit
- USS Centaur (NCC-42043)
The Star Trek: Deep Space Nine Technical Manual describes this vessel as an Excelsior-class starship variant, describing it as being among the ships "constructed from salvaged components, components in work, and custom assemblies fabricated by the individual fleet yards."
The episode "A Time to Stand" needed a shot of a retreating flotilla of Starfleet vessels. To beef out the scene, the production staff built several new ships, kitbashing them out of parts from commercially available AMT/Ertl-Star Trek model kits.
Among the kitbashes was the USS Buckner, which was referred to as the USS Centaur in a later scene of the episode, although a recent photo of the model still shows the original name. The model was not present in the opening flotilla scene, but was featured more prominently later in the episode. The Buckner was constructed from parts of the Reliant (no. 8766) and Excelsior (no. 6630) AMT/Ertl model kits. It was built by Adam Buckner, who still owns the model.  Buckner commented on his build, "The USS Buckner was a ship I built while at Paramount working on Star Trek: Deep Space Nine for a little boy who wanted a Star Trek ship. Gary Hutzel saw the ship and asked if it could be featured in one of his upcoming episodes. I let Gary use the ship. He added the green fluorescent tape for windows and the pink fluorescent paint for engines. As this ship would now be a shooting model, I produced a second model which I sent on to the boy as promised." Buckner further added,
"When I designed the ship, I intended the scale to be based on the Reliant/Miranda bridge and roll-bar. The use of the Excelsior saucer and nacelle parts were convenient as the real world scale of the dish was smaller than the Reliant/Miranda/Constitution/Enterprise dish. It did, however, lead to an unfortunate mis-calculation of scale by the art department when they visited the motion control stage unescorted, and upon seeing the model, made the assumption that the scale should be based on these parts. A further confusion was made when in the making of several art department assets, specifically some books, they "corrected" a number of details without consulting VFX. The most notable "correction" was the bridge to match the dish.
"The detail on this ship was enhanced when I knew it was going to be shot. I added additional greebles to the hull. The intent was to give the ship both a sense of scale (smaller rather than larger, so more greebles rather than a smooth hull) and to give it a sense of a ship that had been customized for its role as a deep intruder with additional detail for engine speed, sensitive long range scanning and increased stealth. This explains the bits on the rear of the dish and the tank treads littered around the dish's edge. And yes, the shuttle bay is a shuttle bay. There was no room for it in the rear." 
As for the use of the fluorescent tape on the model Buckner explained, "The Paint and Tape were for work under UV lights (read "glow in the dark when struck with strong UV radiation"). We used UV for the matte process and some of the window and engine passes. By mixing the paint and selecting the appropriate tape color, the material would glow in a chosen color range, allowing the separation of windows, engines and mattes to different layers by selecting the desired color during transfer from 35mm film to digital, or in the compositing process." wbm
A somewhat redesigned CGI model of the Centaur was commissioned by Adam "Mojo" Lebowitz and built by Ed Giddings for use in various licensed print publications.  Lebowitz himself was responsible for the rendering of the model.  Orthographic views of this model were published in Star Trek Fact Files, no. 298, 2002 and Star Trek: The Magazine Volume 3, Issue 6.
Technical manual Edit
The following specifications were given in the DS9 Technical Manual:
- Production Base: ASDB Integration Facility, Utopia Planitia Fleet Yards, Mars
- Type: Medium Cruiser
- Accommodation: 315 officers and crew
- Power Plant: One 1,500 plus Cochrane warp core feeding two nacelles; two impulse systems
- Dimensions: Length, 381.87 meters; beam, 320.16 meters; height, 78.54 meters
- Mass: 870,000 metric tonnes
- Performance: Warp 9.6 for 12 hours
