ATK 664 was a Lambda-class T-4a shuttle in the Imperial Navy during the Galactic Civil War. When Biggs Darklighter's X-wing, carrying schematics for the first Death Star, broke down, ATK 664 was one of three shuttles sent, under Assault Gunboat escort, to capture the fighter. The shuttle was destroyed by Rebel R-22 Spearheads, sent to protect the disabled X-wing until a repair team arrived.
