A workhorse of Umbrian commerce, the Opaeti is a class of light freighter which has been in production for almost a hundred years. A modular design, it features a bulbous crew section at the front of the vessel and a boxy engine section at the rear, which are connected by a thin structure which can accommodate a number of different cargo modules.

A ubiquitous sight across the battlefields of the Frontier, the GT-7 Larum is the Republic's default general purpose transport craft. Equally capable of atmospheric and spaceborne operations, the Larum is used by both the Repulbic Navy and Army, as well as by a host of planetary law enforcement and first response organizations. For the former clients, it operates as the default inter-fleet shuttle of the URN, while it is used as a light transport and air assault craft by the URA.
