The Hawk is the standard Imperial strike fighter. This fighter is the minimum size capable of mounting thruster plates, so it is the minimum size practical for deep-space combat. Its large Model/9 computer allows it to fight on even terms with much larger vessels, and its small size and high agility make it very hard to hit. One small stateroom is provided for the crew of two, allowing for longer missions.
