A variant of the Arquitens-class command cruiser known as a prison-tug, and sometimes called a tug cruiser, served the Galactic Empire's needs as a tug specifically designed to transport wreckage-prisons. An example of this type of vessel was the one responsible for towing Accresker Jail. This jail operated throughout the Galactic Civil War, but its use was discontinued when a Gundravian hookspore outbreak necessitated its abandonment.
