Venatic class
The Venatic class was a type of hunting starship employed by the Hirogen during 2370s. 

This class of vessel, manned by a crew of roughly seventeen hunters, was considerably larger than both the standard Hirogen ship and the Starfleet  starship. The design also had a major flaw in its sensor system whereby its engines created a "blind spot" in the ship's aft section, in which smaller ships could hide and avoid sensor detection. They are capable of covering a half a light year in less than two hours.

In 2377, the  exploited the blind spot weakness to secretly follow two Venatic-class ships that were pursuing a third ship crewed by Hirogen prey holograms into a nebula. They were later disabled by Voyager. ()
