For the smaller type of Caatati vessel, please see Caatati vessel (small).
A Caatati vessel was a class of starship that was operated by the Caatati refugees following their assimilation by the Borg in 2373. In all thirty Caatati ships, both small and large, transported the last remaining Caatati refugees from the aftermath of the destruction of their homeworld, including several vessels of this larger type.
At least two of these larger vessels were included in the Caatati armada that tracked Voyager down delivering both Voyager's warp core and an ultimatum for more food and provisions. (VOY: "Day of Honor")
