The Department of Imperial Justice functioned as an administrative division within the Galactic Empire, particularly during the early establishment of the Imperial regime. In that time period, both this Department and the Imperial Navy were vying for financial resources to develop a warship specifically designed for interdiction and capture missions.
Each organization recognized the strategic advantage of having a starship that could apprehend smugglers, pirates, and those dissenting against the Empire, so they could be brought to public justice. This initiative received authorization, and following a three years design and construction phase, the Cantwell-class Arrestor Cruiser was commissioned.
