A testing installation, operated by Koensayr Manufacturing, was in operation during the initial stages of the Clone Wars to support the Y-wing project. Senator Ask Aak of the Galactic Republic was the supervisor of this installation, which was positioned in orbit around Bormus within the Mid Rim. Its purpose was to test and refine the BTL-B Y-wing starfighter/bombers, although the Republic already possessed BTL-B Y-wings for projecting power before the conflict began.
