The Parabola-class Freighter is a United Nations Space Command starship classification used in the early 26th century as field engineering and support craft. However by 2525, many of these freighters were independent and used for commercial and civilian use. They are relatively simple craft, with large storage bays, and rotating sections. The rotating sections contained water tanks that would automatically irrigate crops grown in the hydroponics bay in the middle of the vessel. They could carry enough food and water to supply a small city.
Vessels of this class included the Laden. Template:UNSC Ships
