The BTL Y-Wing starfighter, also referred to as the Y-wing starfighter/bomber or more simply the BTL-series, Y-wing fighter, or Y-wing for short, was a series of multi-role starfighter/bombers manufactured by Koensayr Manufacturing. They were originally commissioned by the Galactic Republic during the Clone Wars in the form of the more armor plated and less maneuverable BTL-B Y Wing. After the Clone Wars however, many of the surviving Y-Wings would be scaled down and retrofitted for other roles and go into the service of the Alliance to Restore the Republic during the Galactic Civil War. Those roles being the original two-seat BTL-B Y wing fighter-bomber, its successor, the BTL-S3 Y wing
Starfighter, and the single seat BTL-A4 Y Wing Assault starfighter/bomber.
The BTL-B Y Wing consists of a cockpit section that connects to two large Koensayr ion engines via a reinforced spar and cross-wing. With the cockpit being pressurized and being composed of a transparisteel canopy. Some cockpits even being repulsor-powered escape craft that were fully contained for easy escape if necessary.
The weaponry of the Y-wing consisted of two forward firing laser cannons, either the KX5 or IX4 models. Its weapons and ordinance were designed to penetrate battle cruiser hulls and could have a very devastating effect on their targets. Backing their two forward firing laser cannons they possessed a rotating turret manned by a designated gunner or the pilot themselves. The Y-wing was capable of launching ordinance by possessing a pair of MG7 proton torpedo launchers, each with 6 round magazines. Besides having proton torpedoes
its launchers could launch concussion and cluster missiles if desired. Lastly, the Y-wing was also an bomber capable of carrying and deploying bombs to devastating effect on its targets.
