Hyko was a group of two CR90 corvettes used by the Galactic Empire during the Galactic Civil War. The unit was part of a larger convoy carrying officers, supplies and troopers, that gathered near Orron III en route to the soon to be finished Death Star I. The convoy was due to rendezvous with the BFF-1 bulk freighter Toral which was attacked on the way by Rebel forces. Learning of the rendezvous location from the Toral, the Rebels dispatched Y-wings from Red and Gold squadrons, along with a X-wing from Blue Squadron to destroy the convoy.
