The Trade Federation Sub-Carrier is a vessel from the fictional Star Wars universe.

This underwater vessel was used to transport Mini-Subs piloted by individual Battle droids. The mini-subs would exit through tubes located on the underside of the carrier-vessel. This was a dangerous manouver, as Republic SCUBA Troopers often ambushed mini-subs on their way out, and there was no way of turning back once a sub was racing through the launch-tube.

The Sub-Carrier resembled a Droid starfighter in shape, but dwarfed such craft in sheer size and volume. Each carrier was so big, entire skirmishes could be fought on the topside deck.
