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.
Sienar Fleet Systems 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. This design feature was implemented as a means to protect the ship’s occupants as it touches down.
