A tug is a type of spacecraft designed to tow or otherwise move other vessels. This may be done for repairs or other reasons, such as maneuvering a larger craft in a tight space. They are often small vessels only designed for sublight maneuvering and are not equipped with Slipspace drives. Examples of human craft used as tugs include the Behemoth-class tug and the Bactrian-class freighter. The Covenant are known to use U-shaped tugs to tow damaged ships.
