- Hyperdrive (requires calculations, no real indication of how fast this is since we don’t have any scale of the Empire or distance between where the crews travel - except that it’s called ‘Galactic’)
It should be very fast since in TESB Captain Needa goes to see Vader right after the Falcon disappears from Imperial sensors and mere seconds after Needa’s death Piett says “if the Millenium Falcon went into lightspeed it would be on the other side of the galaxy by now”.
That could be hyperbole.
