B-wing heavy assault starfighters functioned as heavy attack starfighters, mainly deployed as an attack vessel targeting large capital ships, in addition to providing protection for fighter squadrons and transport groups.
Quarrie, a Mon Calamari, initially conceived the B-wing starfighter; Hera Syndulla persuaded him to allow Phoenix Squadron, a rebel cell, to employ his design in their conflict with the Galactic Empire. Often, the B-wing was the most powerfully armed starfighter in operation, drawing influence from both the T-6 shuttle and the V-19 Torrent starfighter. The B-wing line was also known as the "blade wing" series. The Rebel Alliance utilized A/SF-01 B-wing starfighters in numerous engagements during the Galactic Civil War, notably in the Battle of Endor. Subsequently, the New Republic deployed them in the Battle of Jakku. During the First Order-Resistance War, the Resistance forces employed an updated variant in the Battle of Exegol.
