Sunspot Squadron was a TIE starfighter squadron of the Imperial forces. This squadron was under the leadership of General Weir and had its base in the Corellian system.
The squadron, known as Sunspot Squadron, utilized both TIE fighters and TIE interceptors. Furthermore, these fighters were equipped with proton torpedo launchers.
Upon receiving word of the Emperor Palpatine's demise at Endor, Weir, along with his squadron, launched an assault on Coronet. Their objective was to demonstrate the Empire's continued dominance to the local inhabitants. However, Rogue Squadron was present at Coronet during the assault. Following the attack, Rogue Squadron pursued Weir back to his hideout located on Tralus.
In the ensuing battle, Weir and the pilots of Sunspot Squadron engaged Luke Skywalker and Wedge Antilles in aerial combat. With the exception of Weir, every pilot in Sunspot Squadron was shot down by the Rebel forces. Weir was subsequently taken to Sullust to face trial, and any surviving members of his squadron were apprehended by the New Republic.
