The small, heavily armoured ships in which the nomadic Hirogen roam the Delta Quadrant in search of prey, usually with a crew of only two or three, first met by Voyager in 2374.
The Hirogen hunter is the usual vessel of the Hirogen in Star Trek: Voyager. The Hirogen have no settled home and live for the hunt, so their ships are built for tracking and pursuit: fast, protected by monotanium armour that resists Voyager's scans and weapons, and hung inside with the bones and trophies of earlier kills.
The ships are first seen in Hunters, when Voyager uses the Hirogen communications network to receive letters from home and Tuvok and Seven of Nine are taken prisoner aboard one. In Prey a ship with a crew of two tracks a lone member of Species 8472, and Voyager takes its wounded Alpha aboard.
Several of the ships seize Voyager in The Killing Game and turn her holodecks into hunting grounds. Others appear in Flesh and Blood, by which time the Hirogen are hunting holograms.
