Lambda-class T-4a Shuttle

The Lambda-class T-4a shuttle is a standard light utility craft in common use throughout the galaxy, particularly in militaries, 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 is designed as both a cargo and troop transport and could carry 80 tons or 20 soldiers. It also has a crew of six: a pilot, co-pilot, navigator, communications officer, gunner, and engineer. A shuttle can also be piloted by a skeleton crew consisting of a single officer during emergencies. It is also equipped with a Class 1 hyperdrive since its mission profile involves traveling across the Galaxy.

The Lamba is reasonably well-armed, with three double blaster cannons (one rear-mounted) and two double laser cannons. The military version built by Cygnus Spaceworks is armed with ten laser cannons. It was also protected by a powerful deflector shield which is powered by multiple generators. A Lambda is covered by a heavily reinforced hull capable of deflecting laser fire. The shuttle-class is so well armed that it is able to travel across the Galaxy without an escort, thus making it suitable for covert operations.

It was designed by former Cygnus Spaceworks employees, who were lured away by Sienar Fleet Systems with a promise of 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 also rumored to be 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.
