Degra's ship was a Xindi starship utilized by Degra during his construction of the Xindi weapon. He used this ship to travel between various facilities, including Gralik's kemocite refinery, an area of the Calindra system used for testing the weapon, and the weapon's actual construction facility, the latter of which was on the planet Azati Prime.
Degra's ship had a crew of at least ten Xindi-Primates and Arboreals, but it could be operated by a crew of only three. Although it was not at all heavily armed, it was extremely fast and maneuverable. It was capable of landing on a planet and traveling underwater. The vessel had a transporter range of one kilometer. (ENT: "Zero Hour") The craft's interior additionally included a medical bay. (ENT: "Countdown") The ship could also launch an auxiliary shuttle. (ENT: "The Council")
Although Degra himself was killed by Commander Dolim, the crew of the starship Enterprise NX-01 used Degra's ship to catch up to the weapon when it was hijacked by Dolim and the Insectoids, allowing a small team to board the weapon and destroy it from within. At that point, a Xindi-Primate councilor and Jannar became the vessel's commanding officers. (ENT: "The Council", "Countdown", "Zero Hour")
Background information Edit
In scripts written for Star Trek: Enterprise, the bridge of Degra's ship was originally described as an "auxiliary control room." Bearing in mind the many costly episodes in the series' third season, writers hoped that such a description would result in a cheaper set than a "real" bridge set. Once the set was built, however, everyone involved began referring to it as "Degra's bridge." ("Countdown" text commentary, ENT Season 3 DVD)
The rear console from Degra's bridge was actually a heavily reused set piece. Its numerous reuses included an appearance as the aft bridge of a Suliban craft, and another alien in "Silent Enemy". Reconfigured as the back console for Degra's bridge, the set piece had cavities for back lights as well as insets for shaped acrylic panels. This item was sold off on the It's A Wrap! sale and auction. (Star Trek Magazine issue 139, p. 49)
In the video game Star Trek Online, Degra's ship is classified as a Nusuti-class heavy fighter craft deployed by the Xindi-Primate Ateleth Dreadnought (whose design matches the Xindi-Primate starship).
