A fighter wing of the Imperial Starfighter Corps was stationed aboard the Imperial II-class Star Destroyer Bellicose during the Galactic Civil War and as a wing within the Galactic Empire, contained six squadrons, including Beta Squadron. When the Bellicose was frantically chasing a spy of the Rebel Alliance, Beta Squadron was initially deployed to target the spy's UT-60D U-wing starfighter/support craft and damaged it.
However, Commander Tylux deployed his vessel's entire fighter wing to capture the spy. As a result of the dangerous conditions and counterattacks by the spy, the fighter wing was destroyed.
