Cardassian battle cruiser

From Memory Alpha, the free Star Trek reference

A Cardassian battle cruiser is a type of starship utilized by the Cardassian Union during the Dominion War.

The USS Valiant engaged a Cardassian battle cruiser during the early days of the war. (DS9: "Valiant")

It is unclear if the battle cruiser was specifically in reference to the Galor-class, Keldon-class, or a yet unseen class of starship.
