A/SF-01 B-wing starfighter

The A/SF-01 B-wing heavy assault starfighter, known simply as the B-wing starfighter, was one of the largest and most heavily armed starfighters/bombers in the Rebel Alliance'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.
