Twin Koensayr R200 Ion Jet engines, rated at 250 KTU, propelled the BTL Y-wing starfighter in realspace. In an atmosphere, these worked in conjunction with recessed repulsorlift generators to attain speeds of 1,000 kilometers per hour. Each engine featured a sophisticated sensor array housed in domes at the front of the nacelle.
The R200 Ion Jet engines worked in the midst of the Koensayr R300-H hyperdrive unit are housed in the midsection, which was simply a reinforced central spar extending from the cockpit. Attached to this spar was a thin cross-wing, which contained the Thiodyne 03-R cryogenic power cells and connected the craft to the sublight drives.
The R200 Ion Jet Engine served as the Y-wing's main propulsion system. Y-wings were the most common craft in the Rebel Alliance, and R200 engines propelled these sturdy ships in the Battle of Yavin, during the assault on the first Death Star, as well as the Battle of Endor, during the Rebellion's destruction of the second Death Star.

A common component, these engines often wound up in scratch-built starfighters known as "uglies," such as the TYE-wing starfighter.
The R200 Ion Jet engines used in the original trilogy were created with Apollo Saturn V rockets 1/144th scale capped with pantyhose containers.
