In the era of the Galactic Civil War, Grand Admiral Demetrius Zaarin received experimental hyperdrive tech via two Stimner-class Cargo ferries. As a component of a prearranged agreement enabling Admiral Zaarin to scrutinize prototype hyperdrive systems intended for use in the TIE Avenger, Stimner Habeen Ferries connected to Zaarin's Shamus Nebulon-B2 frigate during the Conflict at Mylok IV. Despite intense attacks from Nharwaak rebels throughout the exchange, Stimner 1 & 2 successfully delivered all cargo to Imperial forces without damage.
