Sienar Fleet Systems developed the Lambda Class shuttle (sometimes referred to as the "Imperial Shuttle"). Eventually a subcontract was awarded to Cygnus Spaceworks to produce a much more heavily armed version for military use.
As an elegant example of Imperial engineering, the Lambda Class shuttle is a multi-purpose transport used in the Imperial starfleet. The Empire pressed the shuttle into service for both cargo ferrying and passenger duty. Even the Empire's elite, like Darth Vader and the Emperor Palpatine used Lambda Class shuttles.
With a trihedral foil design, the craft bears a strong resemblance to Incom's popular T-16 skyhopper. It has three wings, a stationary center foil and two articulated flanking wings. When in flight, the side wings fold out for greater stabilization. When landing, the wings fold in, shrinking the vessel's silhouette. Boarding or docking with other spaceships is made possible by a telescoping ramp that extends from the lower forward fuselage.
Though designed primarily for space travel, the shuttle's broad wing surfaces give it stable atmospheric maneuverability. Its large interior hold can carry 20 soldiers, or 80 tons worth of cargo. Since the craft is hyperspace-capable and well-armed, Lambda Class shuttles do not require a military escort, though the increasing threat of Rebel forces means that these ships rarely traveled alone.
The Emperor's personal Lambda Class shuttle was heavily modified, though its exact design specifications remain classified. It was rumored that Palpatine's personal craft even carried a prototypical cloaking shield.
