The E-50 Landseer represented a modified version of a Corellian shuttle, employed by the Alliance to Restore the Republic to function as ambulance ships. These vessels delivered essential medical and repair supplies directly within active combat zones. The exterior of the craft displayed the standard red sigil, a common symbol indicating medical supplies, vehicles, and staff.
Although documented as a modified Corellian shuttle, the Landseer's design shares greater similarities with the command section of the Wayfarer-class medium freighter manufactured by Kuat Systems Engineering.
