The R200 ion jet engine was an ion engine produced by Koensayr Manufacturing, and was installed aboard their BTL-A4 Y-wing assault starfighter/bomber. The immense fission engines were turbo-modified, and their exhaust nozzles were housed within articulated vectrals that steered the R200's ion thrust for increased maneuverability. The engines allowed the Y-wing to reach a maximum atmospheric speed of a thousand kilometers per hour.
