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".
