The Trenac was a Dakar-class heavy destroyer that saw service with the Cardassian Guard during the 24th century.

In 2369, the Trenac came to the aid of the freighter Par'rhen after it suffered an engine failure and was caught in the gravity well of the Garshep 5-11 black hole. (Ship Recognition Manual, Volume 2: Starships of the Cardassian Union)
