Fleet tenders were non-combatant capital ships attached to fleet forces like the Imperial Navy and the New Republic Defense Force, designed to carry military cargoes along interstellar supply-lines to replenish front-line vessels. Little is known of Imperial fleet tenders such as the Moff Weblin, but it is known that 300m Star Galleon cargo/escort frigates were used as support ships for Star Destroyers by Grand Admiral Thrawn, while the full variety of cargo vessels in an Imperial Force Support ranged from corvettes to massive Field Secured Container Vessels.
