Created in Iacon's Drydocks, the Spirit of Freedom was the first brand new Ship of the Line for the Autobots in ages. It was a long ship with large hallways that extended the length of the ship. Cast mostly in a brownish grey, long pipes carrying redundant energy conduits, and thick blast plating were seen all throughout the ship. Floodlights from the top and occasional floor panels provided adequate lighting for the Bots on board.
In June of 2015, during its maiden voyage to retrieve the damaged body of Ultra Magnus, the Freedom was ambushed by the Decepticons, who tried to use it as a giant flying bomb to destroy Iacon. The Autobots managed to save Iacon, but the Freedom was lost in the assault.
