Attack cruiser is a term used by the Klingon Defense Force (among others) for some large combat-oriented starship classes.

Technically, the term appears to be equivalent to "battle cruiser", but its usage tends to be associated with the larger ships developed in the 24th century, and most specifically the Vor'cha class.
