Jeffrey was a CR90 corvette in the Rebel Alliance during the Galactic Civil War. It was supplied in the Cron Drift by the Delta-class DX-9 stormtrooper transport Magnus in order to man the AX-235 outpost, and was also delivered some stolen Imperial communications satellites by the BFF-1 bulk freighter Ojai.

An Imperial force consisting of four transports, escorted by Alpha-class Xg-1 Star Wings, attacked the rendezvous but were defeated by X-wings flown by Keyan Farlander and Puck Naeco, allowing the transfer to take place.

The Jeffrey then replaced several Imperial satellites with the Rebel ones to monitor Imperial communications and report to listening post AX-235. The satellites proved essential in discovering the Death Star I project.
