Ace Squadron was a unit of RZ-1 A-wing interceptors assigned to the New Republic Defense Force, and this squadron of starfighters was under the leadership of Captain Pash Cracken. Pash Cracken was the offspring of Airen Cracken, a General in charge of New Republic Intelligence and a native of Contruum.
Originally, Ace Squadron existed as part of a larger fighter wing called Cracken's Flight Group. This group consisted of former Imperial pilots who had switched allegiances to the Rebel Alliance with Cracken. However, due to losses, the surviving pilots were reorganized to form the singular Ace Squadron. Following this reorganization, Ace Squadron was placed under the command of Commander Varth's wing.
