The Xanthian-Class science vessel, unlike its predecessor the Anaximander-Class, has been refitted with a new triangular design, making it one of the fasted ships in the fleet. The three main contributors to the Xanthian's superior speed are (1) its slightly narrower, longer body lines, (2) the fitting of the nacelles directly against main hull, and (3) the modified and upgraded Targanide Warp Drive.
