Two Cargo ferries from group Stimner brought experimental hyperdrive technology to Grand Admiral Demetrius Zaarin during the Galactic Civil War. During the Conflict at Mylok IV, Habeen Ferries Stimner docked with Zaarin's Nebulon-B2 frigate Shamus as part of an arranged deal for Admiral Zaarin to inspect prototypes for new hyperdrive systems suitable for the TIE Avenger. Stimner 1 & 2 withstood heavy fire from Nharwaak dissidents during the transfer, yet all cargo arrived into Imperial hands unharmed.
