The Ivarix-class has been described as having a distinctly avian feel, with a flat thick neck reaching forward to the main section, holding two warp nacelles via wing-like supports. Ivarix-class ships were typically armed with disruptors, photon torpedoes, and plasma-energy weapons. The class was similar in size and capability to Federation Excelsior-class starships.
