Cygnus Spaceworks was a manufacturer of small craft, such as shuttles and starfighters, primarily of a military nature. Approximately half of Cygnus' designs were merely modifications and upgrades to previously existing craft. After years of producing craft for the Galactic Republic, Cygnus quickly became loyal to the Galactic Empire. Cygnus Spaceworks remained loyal to the Empire even after the rise of the New Republic, although many of the shuttles jointly produced by Cygnus Spaceworks and Sienar Fleet Systems fell into the New Republic's hands.
