An Auxiliary Ship is a type of naval vessel that supports the operations of combat ships. These ships are not primarily designed for combat but provide essential services such as supply, repair, and transportation. They play a crucial role in maintaining the operational readiness of a navy by ensuring that combat ships have the necessary resources and support. Examples of auxiliary ships include replenishment oilers, which supply fuel, and hospital ships, which provide medical care. Other types include tugboats for maneuvering larger vessels and amphibious assault ships that transport troops and equipment. Together, they enhance the effectiveness of a naval fleet.
