Slayn & Korpil was a manufacturer owned and operated by a Verpine colony in the Roche asteroid field. Shortly after the Battle of Yavin, the company, under the supervision of then-Commander Gial Ackbar, contributed the B-wing starfighter to the war efforts of the Rebellion; this ship saw much use in the climactic Battle of Endor. Along with the three standard B-wing starfighter models, the company made limited-production B-wings as well. Slayn & Korpil also made fighters for the Old Republic during the Clone Wars.
