The Xindi-Primate starship used by Degra, designer of the Xindi weapon, which Archer first captures to trick him and which later escorts Enterprise to the Xindi Council and chases the weapon to Earth.
Degra's ship is the Xindi-Primate vessel commanded by the scientist Degra in the third season of Star Trek: Enterprise. In Stratagem the Enterprise crew capture it, wipe the memories of those aboard and stage an elaborate deception in a simulated shuttle so that Degra will reveal where the weapon is being built.
Once Degra comes to believe Archer's warning about the Sphere-Builders, the ship becomes an ally. In The Forgotten Degra destroys a Reptilian vessel to keep their meeting secret, and in The Council his ship leads Enterprise to the Xindi Council. Degra is murdered aboard it by the Reptilian commander Dolim.
In Countdown and Zero Hour the ship, being faster than Enterprise, carries Archer and his assault team in pursuit of the weapon as it heads for Earth.
