An elegant example that stands apart from typical brutish 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 these shuttles.
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.The well-armed vessel has two forward-facing double laser cannons, two wing-mounted double cannons, and a rear-facing double laser cannon. It is equipped with a hyperdrive.
The Lambda was designed as both a cargo and troop transport and could carry 80 tons or more than 20 soldiers. It had a crew of six: a pilot, co-pilot, navigator, communications officer, gunner, and engineer. A shuttle could be piloted by a skeleton crew consisting of a single officer during emergencies. It was also equipped with a Class 1 hyperdrive since its mission profile involved traveling across the galaxy.
It was also protected by a powerful deflector shield, which was powered by multiple generators. A Lambda was covered by a heavily reinforced hull capable of deflecting laser fire. The shuttle class was so well armed that it was able to travel across the galaxy without an escort, thus making it suitable for covert operations.
In an emergency the cockpit could be jettisoned from the main body and travel a short distance under sublight speed. The lifeboat did not have enough space for all passengers when the shuttle had its full complement and therefore priority was given to the most senior officers onboard.
It was designed by former Cygnus Spaceworks employees who were lured away by Sienar Fleet Systems, which promised them high salaries, a portion of future profits, and even personal star yachts. Although these shuttles were primarily manufactured by Sienar, Cygnus was subcontracted to build a more heavily armed military version. It was the immediate successor of the Theta-class T-2c shuttle, and was first introduced in 19 BBY at some point after the Imperial subjugation of Kashyyyk.
