The Cygnus Spaceworks Alpha-class Xg-1 Star Wing, also known as the Xg-1 Starwing and commonly referred to as the Assault Gunboat, was one of the Axis's first general-deployment starfighters to be equipped with deflector shields and a hyperdrive. The Xg-1 Gunboat is used by the Axis of Empires. Morrigan is known to be piloting the Xg-1 Gunboat.

The 10-meter-long Xg-1 was based on a tri-wing design similar to the Lambda-class shuttle, another craft that Cygnus Spaceworks designed. Like the Lambda shuttle, the Star Wing had a fixed dorsal wing flanked by a pair of lateral folding wings. When landing, the lower wings folded upwards. However, the Xg-1 had a sleeker cockpit and warhead/engine pods along the side of the hull. It had two additional folding wings that protruded diagonally from the side pods, at an angle reflexive to the lateral wings. These secondary wings afforded the Xg-1 significantly increased maneuverability over its shuttle counter-part. When in flight position, the wing configuration resembled an inverted five-point star, thus the name "Star Wing".

Its armament consisted of two chin mounted laser cannons, two ion cannons above the cockpit, and a pair of general purpose warhead launchers. The Gunboat could also carry the tractor beam weapon developed for the TIE Avenger and newer Imperial starfighters; the only known use of this was during Ciri's campaign in the Xarrina system to snare enemy craft.
