A surface ship is a type of watercraft that operates on the surface of the water, as opposed to submarines, which travel underwater. These ships are designed for various purposes, including military operations, cargo transport, and passenger travel. They can vary in size and function, from small fishing boats to large container ships and naval vessels. Surface ships are equipped with various technologies and systems to navigate, communicate, and perform their specific tasks. They often feature decks for loading and unloading cargo, living quarters for crew members, and advanced navigation systems. Examples of surface ships include destroyers, cargo ships, and cruise liners.
