Suliban shuttle (right).
The Suliban shuttle is a small spacecraft employed by the Suliban, capable of atmospheric flight and landing.
Several vessels of this design were confiscated by the Tandarans and were kept in a hangar at Detention Complex 26. When Jonathan Archer helped free the Suliban detained at the complex, their objective was to make it to the hangar and escape via these shuttles. (ENT: "Detained")
