Millennium Falcon's Background
"You know, that ship's saved my life quite a few times. She's the fastest hunk of junk in the galaxy!" ―Lando Calrissian
The Millennium Falcon was a Corellian YT-1300 light freighter used by the smugglers Han Solo and Chewbacca during the Galactic Civil War. It was previously owned by Lando Calrissian, who lost it to Solo in a game of sabacc.
Its aged appearance belied numerous advanced modifications to boost the ship's speed, weapons and shield, including sensor-proof smuggling compartments, which were used during the rescue of Princess Leia Organa to evade Imperial stormtroopers. Afterwards, the Millennium Falcon saw further action when Solo chose to join the Rebels during the Battle of Yavin, where it was able to sneak up on Darth Vader's TIE Advanced.
After Han was captured on Bespin, Lando took command of the Falcon once more to search for him, and later flew the ship at the Battle of Endor, where it entered the Death Star II and destroyed it from within. During this battle, the starship's circular sensor dish was knocked off as Calrissian piloted it through the Death Star's interior.
In addition to its renowned hyperdrive, which made the Falcon boasted as the "fastest ship in the galaxy," the ship was equipped with a backup hyperdrive. Compared to the primary engine, it was much slower and often took several weeks or months to reach the nearest star system. It also had a dejarik table featuring creatures found throughout the galaxy.
At some point over the following thirty years, the sensor dish was replaced with a rectangular model.
