The Four Freedoms Class is a cargo freighter that is used by the Systems Commonwealth to ship raw materials to allied and neutral worlds, drifts, and other habitats. It has no offensive weapons, because many planets have laws or regulations regarding weapons on commercial vessels entering their atmostpheres. Also, as the ship is a cargo-carrying vessel, it is obviously designed to carry a large quantity of materials. It has the minimum amount of crew so that there is less room taken up by life support systems, crew quarters etc., which allows more room for cargo.
