Starship of the Xindi-Primates, the species of the weapon designer Degra, whose vessel was captured and used in an elaborate deception in Stratagem.
Xindi-Primate ships were flown by the humanoid Primates, one of the five Xindi species. Their best-known member was Degra, the scientist who led the design of the weapon meant to destroy Earth.
In Stratagem, Enterprise captured Degra and his crew near a weapon test site. Archer then staged an escape from an Insectoid prison camp aboard a simulated shuttle, convincing Degra that three years had passed and that they were friends, in order to learn where the weapon was being built. Degra later became an ally of Archer before he was killed by the Reptilian Dolim.
