Halberd, an escort carrier of the Ton-Falk-class, served within the Imperial Navy.
This vessel was positioned in proximity to Comm Center, where it endeavored to rescue the installation during a raid by the Rebel Alliance. This attack was part of a covert mission to get in touch with an Imperial defector. The Halberd appeared just as Python finished downloading information from Comm Center, and it launched TIE bombers in an attack against the Corvette.
A-wing pilots, including Ace Azzameen, successfully shielded the Corvette from incoming missiles until Python finalized its mission.
