The A/SF-01 B-wing heavy fast attack starfighter, known simply as the B-wing starfighter, was one of the largest and most heavily armed starfighters/bombers in the Alliance Joint Navy's fleet. The name B-wing came from the craft's appearance to a "B", when upright, the outline of the upper half and the lower half makes a B shape, although its swordlike shape in attack mode has earned it the nickname "Blade-wing", which may be another reason for the "B" prefix. Known as "crosses" due to their distinct shape, the B-wing was designed by the Verpine company Slayn & Korpil in cooperation with then-Commander Gial Ackbar as part of the Shantipole Project. The B-wing, though difficult to fly, participated in numerous engagements across the Multiverse. it is used by the Alliance of Nations. Vesemir of the Ssil'jiiy Universe and Margaret Edmondson are very-well known B-Wing ace pilots during the war.
- "Because the cockpit is surrounded by a unique gyro-stabilization system, the pilot always remains stationary, even as the rest of the ship rotates during flight."
- ―General Carlist Rieekan[src]
Somewhat reminiscent of the H-60 Tempest bomber, and using a wing configuration similar to Slayn & Korpil's earlier V-19 Torrent starfighter,[source?] the A/SF-01 B-wing assault starfighter had a somewhat ungainly appearance resembling a top-heavy cross when fully unfurled. The primary airfoil took up the length of the hull, with the cockpit at one end and a weapons pod at the other end. Two S-foils amidships on either side of the airfoil also held weapons. In addition, the B-wing's main body was essentially a single long wing with a pair of folding S-foils. Its primary role was an attack vessel targeting the Axis and Horde's capital ships, although it also did escort duty or X- and Y-wing fighter squadrons and Alliance convoys, and were also able to be deployed for assaults on space-based or planetary facilities.
