77 Squadron was a starfighter squadron that served as part of the New Republic's starfighter corps during the Galactic Civil War. Mostly consisting of X-wing starfighters, the squadron participated in the Battle of Jakku under the designation "Blue Squadron." After receiving reports of an Imperial Star Destroyer near Jakku, Admiral Gial Ackbar sent a reconnaissance team to investigate with 77 Squadron accompanying them as a security escort. Upon emerging from hyperspace, the group quickly ran into a group of TIE fighters guarding a Star Destroyer orbiting the planet. In the skirmish that ensued, the Star Destroyer was taken out and the recon team quickly returned to base.
