Hirogen warships were small, heavily-armed warships used by Hirogen hunters during the 2370s as they hunted throughout the Delta Quadrant. This class of vessel was usually piloted by two Hunters. The vessels were equipped with monotanium armor plating, and had dicyclic warp signatures.
The USS Voyager first encountered a Hirogen ship in mid-2374 when they accessed a Hirogen relay station in order to send the Doctor to the Alpha Quadrant.
