Angel's Supremacy was a DA-class Cruiser, it belonged to Darth Angel, a Sith assassin whom the Jedi and Clones feared. Since it belonged to Darth Angel, the shielding was heavy and had custom colored decals painted all over it. About only 23 were built for the Dark Angels of Corellia. Darth Ven and Darth Varanee had their own DA-class cruisers as well. Ven named his Angel's Wraith, while Varanee named hers Darkness of the Eclipse.
The Angel's Supremacy was really strong against Venator Attack Cruisers. Though after the Declaration of a New Order, newly appointed Emperor Palpatine found out about the Dark Angels of Corellia whereabouts and sent the Imperial Military to Kaai and remove them while Imperial-class Attack Cruisers encountered DA-class Cruisers, the Imperial Navy dealt with the cruisers while ground troops went by the blockade. After Darth Vader and the 501st Legion finished off the Dark Angels, the Imperial fleet destroyed the last of the DA cruisers while the Angel's Supremacy, suddenly, disappeared without a trace.
