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 smaller type.
A number of small Caatati vessels were among the armada encountered by USS Voyager in 2374. They were capable of carrying a crew complement of eighty-eight, and were found to be far inferior to Voyager, but in numbers posed something of a threat to the Federation starship. (VOY: "Day of Honor")
