The Wayfarer-class medium freighter represents a specific type of medium-sized freighter. Senator Bail Organa's resistance group employed this class of ship during the blockade of Ibaar. Among the vessels of this class were Cargo Comet and Cargo Sky, tasked with the mission of transporting essential goods to the rebels located on Ibaar.
The initial reference to the Wayfarer-class medium freighter occurred in Dawn of Rebellion. This is a canon supplementary resource for roleplaying, drawing inspiration from both Star Wars Rebels and Rogue One: A Star Wars Story. Fantasy Flight Games published this book in 2018. The authors include John Dunn, Tom Sorenson, Sterling Hershey, Jonathan Julius, Keith Ryan Kappel, Tim Huckelberry, Jason Marker, and James M. Spahn.
Prior to this, the freighter made appearances within Star Wars Legends. It featured in works such as Night's Homecoming, Incursion, and In the Name of the Maker.
