Bravo 029 was a YSS-1000 Sabre piloted by SPARTAN-B312 and Jorge-052 during Operation: UPPERCUT. It was customized for orbital defense. During Operation: UPPERCUT, Bravo 029 was one of the Sabres that defended Anchor 9 and later assaulted the Covenant corvette Ardent Prayer and landed on its hull. It was later destroyed along with the corvette, as well as the supercarrier Long Night of Solace when the Shaw-Fujikawa Translight Engine used as makeshift bomb went off inside the corvette.
