Husnock warships were large starships operated by the Husnock prior to 2366. This type of vessel was much larger than a Galaxy-class starship, capable of being seen from the surface while in orbit, and capable of destroying all life on a planet.
In 2366, a Husnock warship attacked and destroyed a Federation colony on Delta Rana IV. Unknown to the Husnock, an energy lifeform known as a Douwd was also living on the planet in the form of Kevin Uxbridge. In retaliation for the Husnock attack, the Douwd used its enormous powers to completely destroy the entire Husnock race. (TNG: "The Survivors")
- Some have speculated that the warship which Uxbridge created to ward of the USS Enterprise-D from Delta Rana IV was a recreation of a Husnock warship. One source stating this is Decipher in their Customizable Card Game. However this assertion is not directly supported by canon.
