 Small ships are built in a ship yard while the larger ships require a space dock for construction . Ships range from the small Scoutship ( used to discover new asteroids ) , to the gigantic Command Cruiser ( which is used for transporting combat fleets over vast distances that they would otherwise be unable to travel without refueling ) . Each ship has a limited number of hardpoints to which weapons and other devices can be attached , and ships can be grouped together into fleets .
