A missile boat was a diminutive warship that diverse groups operating within the Unknown Regions employed. These vessels were equipped with a complement of missiles. The Chiss Ascendancy made use of missile boats, and the Nikardun Destiny employed Nighthunter-class gunboats. Certain missile boats belonging to the Chiss Ascendancy engaged in a battle over Primea in collaboration with the Vak Combine, opposing the Nikardun Destiny as a component of the Chiss Expansionary Defense Fleet's Picket Force Six.
