Lightning Squadron was a BTL Y-wing starfighter squadron that served as a part of Han Solo's task force during the hunt for Warlord Zsinj and his Super Star Destroyer Iron Fist.
Lightning Squadron was stationed aboard the starfighter carrier Battle Dog and flew as a part of Wedge Antilles' assault force during the attack on the Iron Fist in the Vahaba system. Later, it formed part of the Mon Remondas defensive screen during the Battle of Selaggis that followed. It was highly likely that the squadron suffered heavy losses when Zsinj's decoy, Second Death, was detonated.
