The CR-series, also referred to as the CR line, represented a family of corvettes produced by the Corellian Engineering Corporation. It encompassed models such as the CR56 corvette, the CR70 corvette, and the CR90 corvette. Notably, the Sphyrna-class Hammerhead corvette served as a forerunner, preceding the development of the CR-series by a significant period.
The CR-series acquired alternative names such as Alderaanian diplomatic cruisers, Alderaanian cruisers, Alderaanian starships, or Alderaan cruisers, stemming from the widespread employment of the CR70 and CR90 corvettes as diplomatic cruisers by the Royal House of Alderaan.
