A naval fleet is a large group of ships organized for military operations at sea. These fleets can include various types of vessels, such as aircraft carriers, destroyers, submarines, and support ships. Each ship plays a specific role, contributing to the overall mission of the fleet, which may involve defense, power projection, or humanitarian assistance. Naval fleets are typically operated by a country's navy, such as the United States Navy or the Royal Navy. They are essential for maintaining maritime security, conducting naval warfare, and supporting international operations. The coordination and strategy of a fleet are crucial for effective naval power.
