Lambda-class T-4a shuttle/Legends

Lambda-class shuttle "Let's see what this piece of junk can do."

- Han Solo, commenting on Tydirium

The Lambda-class T-4a shuttle was a standard light utility craft in common use throughout the Imperial military as a transport for troops and high-ranking individuals.

Characteristics
"I doubt the Empire had Wookiees in mind when they designed her, Chewie."

- Han Solo to Chewbacca



The Lambda-class shuttle was based on a tri-wing design with a central stationary wing flanked by a pair of folding wings. When in flight position, the wing configuration resembled an inverted Y. When landing, the lower wings folded upwards.

The Lambda was designed as both a cargo and troop transport and could carry 80 tons or 20 soldiers. It also had a crew of six: a pilot, co-pilot, navigator, communications officer, gunner, and engineer. A shuttle could also 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.

The Lambda was reasonably well-armed, with three double blaster cannons (one rear-mounted) and two double laser cannons. The military version built by Cygnus Spaceworks was armed with ten laser cannons. 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.

History
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 shuttle, and was first introduced in 19 BBY at some point after the Imperial subjugation of Kashyyyk.



The Lambda-class shuttle was used along with the TIE/sh shuttle to transport officers between ships in a fleet. Lower ranking officers usually used the TIE shuttle, while the larger Lambda-class shuttles were reserved for flag officers. The Lambda was also favored by Imperial personnel because it was heavily armed and shielded. Thus, the vehicle class found itself used by key Imperial officials including Emperor Palpatine himself and Darth Vader. These high-ranking officials often converted the cargo space into personal quarters and equipped them with secure HoloNet transceivers directly connected to Imperial Center. Palpatine's shuttle was equipped with extra shielding, for obvious reasons. It was also rumored that it was equipped with a cloaking device for added protection.

The Lambda-class shuttle Tydirium was captured by the Alliance to Restore the Republic and used to insert a strike team on the forest moon of Endor. In addition to this, the Alliance maintained a fleet of Lambda-class shuttles as support ships, with the Alliance logo painted on the central wing.

With the fall of the Empire, Cygnus also manufactured a variant of the shuttle similar to the original version. The Lambda also found itself used by various sectorial and planetary security forces including the New Republic and the Galactic Federation of Free Alliances. Jacen Solo and Ben Skywalker used an armed Lambda-class variant during their mission to Adumar in 40 ABY.

Behind the scenes

 * Lambda shuttles were erroneously referred to as "Tyderian class" in some sources, a misunderstanding originating from the shuttle Tydirium.


 * The name Lambda comes from the Greek letter (uppercase Λ, lowercase λ) whose lowercase form resembles the general arrangement of the shuttle's wings. The designation of this shuttle type as Lambda-class dates back to the novelization of Return of the Jedi (1983), and was picked up by contributors to West End Games when that company began writing material about the shuttle.


 * The Sienar/Cygnus connection has occasionally been a source of confusion, but the StarWars.com Databank indicates that the Lambda's predecessor was built by Cygnus and the designers of that shuttle were lured away by Sienar, who then built the original Lambda shuttles. Cygnus then built the Lambda under license from Sienar. Sienar and Cygnus also cooperated on the Sentinel-class landing craft, a derivative design.


 * Another derivative design known as the Delta-class JV-7 escort shuttle was seen in the X-wing computer game series. The craft library of the game X-wing Alliance describes it as a "militarized version of the Lambda-class shuttle built under subcontract to Sienar," but little else is known about its design and manufacturing history.
