The Tyderian, or Lambda, Shuttle was designed by Cygnus Spaceworks to transport important personnel from one location to another. It can be used in both vacuum and atmospheric conditions, and has hyperspace capability. The Lambda Shuttle can be heavily shielded, or only lightly armed and armored.

The Lambda Shuttle is not unique to the Imperial navy, but is in use by the Rebels, pirates, and wealthy individuals.

The Lambda-class shuttle was designed to swiftly transport personnel and cargo between ships in the Imperial fleet. Sienar Fleet Systems built the original shuttles to carry up to twenty passengers in relative safety, for the Lambda-class has standard reinforced hull plating and multiple shield generators. The Lambda-class is also fitted with a hyperdrive for travel between fleets. The basic Sienar Lambda-class shuttle measured 20 meters in length, and could be armed with three double blaster cannons and two double laser cannons. It was designed to have a crew compliment of four, with two additional positions for communications and power regulation.
