The Arrestor, an Acclamator-class assault ship, fought for the Republic Navy throughout the Clone Wars, including participation in the Mission to the Chaykin Cluster. This vessel continued its service after the Clone Wars ended, joining the Imperial Navy during the Galactic Civil War.
Rothana Heavy Engineering constructed the Arrestor, a gray colored _Acclamator-class assault ship. This ship, exclusive to the Galactic Republic, was not sold to external entities. It possessed turbolasers and these were used to help destroy at least one Lucrehulk-class battleship.
In the year 21 BBY, during the Mission to the Chaykin Cluster which took place in the Corbantis system, the Arrestor, under the command of Captain Talbot, was dispatched to support the clone commando unit known as Delta Squad. Their objective was to neutralize Separatist and Trandoshan forces aboard the derelict Acclamator-class assault ship named Prosecutor. The Arrestor aided in the destruction of a Lucrehulk-class Droid Control Ship while Delta Squad managed to reactivate Prosecutor's automated turbolaser batteries.
The combined efforts of the Arrestor and Delta Squad successfully defeated the CIS-Trandoshan slaver coalition, presumably returning Prosecutor to active service for the Republic.
Eventually, the Arrestor was inducted into the ranks of the Imperial Navy.
