The Dur'nat-class was a type of assault cruiser that saw service with the Cardassian Guard during the 24th century. The Dur'nat was one of the Union's more powerful cruisers, equipped with multiple spiral wave disruptors and six torpedo launchers. It was a popular vessel among ship commanders even though many felt it was too slow. (Ship Recognition Manual, Volume 2: Starships of the Cardassian Union)
