Degra's ship

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. The craft's interior additionally included a medical bay. The ship could also launch an auxiliary shuttle. 

Although Degra himself was killed by Commander Dolim, the crew of the starship 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. 

Background information
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." ( text commentary, ENT Season 3 DVD)
