The Syliure-31 long-range hyperdrive module, also known as the Syliure-31 hyperspace docking ring (sometimes spelled Syluire), represented a hyperdrive docking ring manufactured by TransGalMeg Industries, Incorporated. Production occurred in the years leading up to and encompassing the period of the Clone Wars. Its purpose was to facilitate hyperspace journeys for starfighters too compact to contain an integrated hyperdrive system.
Specifically, the Syliure-31 was engineered for use with the Kuat Systems Engineering Delta-7 Aethersprite-class light interceptor. However, it also served as a transport mechanism for Delta-7Bs and Delta-12 Skysprites. The ring featured two substantial hyperdrive engines, positioned on opposing sides. The structure could bisect, revealing a socket designed to secure the fighter. These engines incorporated Class 1.0 hyperdrives, enabling a range of 150,000 light years.
As the Eta-2 Actis-class interceptor gained prominence and acceptance as a successor to the Delta-7 and Delta-7B, TransGalMeg responded by developing the larger Syliure-45 hyperdrive module. Despite the newer model's widespread adoption by the time of the Battle of Coruscant, some Syliure-31 units remained operational, stationed in orbit above the Jedi Temple.
During the Galactic Civil War, at least one Syluire-31 was still functioning in orbit around Geonosis. Wedge Antilles subsequently utilized it, alongside a Delta-7 Aethersprite-class light interceptor recovered from Geonosis, to evacuate the system following an ambush.
