An old classification of starship used prior to the establishment of the Unity Protocol, the NR-1000 is a very common sight in the Aleph Cluster. They are prized for their capacity to transport persons without starship over large distance or deliver specialty goods very quickly as rapid courriers - something essential in the increasing exponent niche of a world filled with increasing automation.
They are primarily known for their rounded hulls and heavy forward adjustable cargo calipers designed to lock onto a trailer is then carried infront of the craft. Lacking particularly powerful engines, their small size is designed to make the most optimal use of a Warp Rail, travelling as close to the middle as possible. Making up for the intense forces potentially expressed on their hulls, NR-1000 light freighters are very hardy and well built and as such, have lasted a very long time: some handed down between generations of family businesses with simple small changes like cabin alterations, engine upgrades and reactor changes keeping the nearly 200 year old hull relevant.
