The CR90 corvettes, also known as Alderaan Cruisers, Corellian corvettes, or blockade runners, were manufactured by the Corellian Engineering Corporation. They were in use within the late Galactic Republic. Later many vessels would be appropriated by the Rebel Alliance against the Galactic Empire, despite not being designed as a combat-oriented vessel. The ship-class is the first to be seen in Episode IV. It also appears in Episode VI, Episode III, Rogue One, and in the TV-series The Clone Wars and Star Wars Rebels.
