The Rockcan served as the individual starship belonging to Gideon Smith, who was a miner. This particular vessel was a compact mining craft, enhanced by the addition of turbolasers. In an incident involving Luke Skywalker, Gideon Smith piloted the Rockcan to both 24 Tredway and Tol Ado as part of the operation to save Erling Tredway. Throughout this rescue effort, the Rockcan provided transport for the wounded Dena Tredway, bringing her to the hidden asteroid station utilized by Doctor Ire Eleazari.
