The Lambda-class T-4a shuttle, also known as the Lambda-class shuttle, Imperial Lambda, Imperial Transport or the Imperial Shuttle, was a multi-purpose transport with a trihedral foil design used by the Galactic Empire during the Galactic Civil War, and was considered an elegant departure from the standards of brutish Imperial engineering. The shuttles were often used by high-ranking Imperial officers and such dignitaries as Darth Vader and Emperor Sheev Palpatine, but were more commonly found ferrying stormtroopers or cargo. low poly. model. A hyperdrive-equipped multi-purpose transport, the Lambda-class T-4a shuttle was developed by Sienar Fleet Systems for use in the Imperial Navy.[1] Measuring 20 meters in length, the Lambda-class could attain a max speed of 850 kph, and was one of the more common Imperial ships found throughout the galaxy—along with its nearly-identical counterpart, the Sentinel-class landing craft. It had three wings: one tall, dorsal stabilizer that remained stationary, and two lower articulated flanking wings. While in flight, the wings folded outwards for greater stabilization, while during landing procedures the wings folded inward, reducing the vessel's silhouette. This triangular shape was considered elegant and a departure from the Empire's usually crude designs.[5]
