Prison ship (Earth-5875)

Prison ships are ships meant exclusively for the transportation of criminals, ore and resources to penal colonies. Many of these ships are converted large freighters, and, as a precaution against possible uprisings, they are mostly equipped with minimal weaponry and defenses on board, having to rely on either CMB or UNSC escorts for protection. Prison ships also feature sealed safe rooms for its personnel to go in the case of uncontrollable riots.
