An additional, though less common, Y-wing BTL-A4 variant known as the "LongProbe," this ship was equipped with a nav computer, backup hyperdrive, advanced scanners, and an extended fuel supply in place of the weapons systems officer. The "LongProbe" was used primarily for long range scouting missions. On such missions longprobes operated in recon teams known as "Longprobe Y-wing Recon Teams". The Y-wing was already nearly obsolete by the close of the Galactic Civil War, being slow and ungainly compared to other Alliance fighters; but it was still fielded by many planetary defense forces, mercenaries, and pirates.
