The class had a design reminiscent of previous eras of Corellian shipbuilding, with elements similar to the Consular-class and DP20 frigate. It was one of the largest space transports available on the market, and was mainly used by corporations that wanted to move large amounts of goods with a minimum amount of ships.
The Corellian Engineering Corporation was able to produce these ships despite Imperial restrictions by convincing the Imperial bureaucracy that the YZ-2500 will help to stabilize trade lines plagued by pirates. Many of those ships found their way into the hands of Galactic Alliance Core Fleet. A famous YZ-2500 transport was the Pride of Corellia, captained by Admiral Nict, as a ship in the Core Fleet, during the Sith–Imperial War. The vessel was destroyed with all hands lost during the Battle of Caamas.
