The most versatile of all Rebel starfighters, the Y-Wing is capable of handling virtually every mission with only slight modifications. Specifically the inclusion of Ion cannons in its arsenal make it a popular starfighter amongst pirates. Like the famous TIE fighter, the Y Wing is powered by a twin Ion engine, but unlike the TIE this ship has both engines away from the main hull, giving it the characteristic Y shape when viewed from above or below. A drawback to this design has proven to be the fact that it now leaves the Y wings power couplings in an exposed position, making them a preferred target in dogfights. This variation of the Y wing designated the BTL-S3 is a two man variant, usually a pilot and a gunner. It has superior shields to its sister ship, the BTL-A4 Longprobe because of the inclusion of an extra Novaldex power generator. The extra power is also needed for the weapons. The proton torpedo magazine, located just under the passenger/gunner seat was removed for the BTL-A4 model to make room for the extra sensor package.
