Cargo carrier
From The Stargate Omnipedia
Large transport vessel, approximately the size of an Al'kesh. Multiple containers can be linked in a chain via tractor emitters. Craft such as Al'kesh are capable of towing the ships through space. It is unclear if the cargo containers can enter hyperspace while tethered together, but based on their function this seems likely.
Following the defeat of the Goa'uld, many cargo carriers fell into the hands of the Lucian Alliance to be used for conveying kassa between Lucian-controlled territories.
