This Star Wars papercraft is BTL-A4 Y-wing, one common design of BTL Y-Wing Starfighter, a mainstay of the Alliance Starfighter Corps and often used as an assault bomber to attack enemy capital ships directly in conjunction with the later B-wing starfighters. The paper model created by Slawek.
he BTL-A4 was a one-man version of the S3, which removed the gunner position and locked down the overhead ion cannon.
It was used commonly by pirate, mercenary, and private defense forces, and therefore was also used by the early Rebel Alliance as the primary starfighter for bombing and disabling roles. As the BTL-S3 became the primary Y-wing variant of the Rebel forces, the A4 was still kept in many units as a supplementary craft. However, Red and Gold Squadrons favored the A4 variant of the Y-wing and used it with distinction in several climactic battles, such as the Battle of Yavin, the capture of the Death Star II plans from the Imperial freighter Suprosa, and the subsequent Battle of Endor.
