A naval fleet is a group of ships and submarines organized for military operations at sea. These vessels can include aircraft carriers, destroyers, frigates, and support ships, all working together to achieve strategic objectives. The fleet is typically operated by a nation's navy, which is responsible for defending maritime interests and ensuring national security. Naval fleets can also participate in humanitarian missions, disaster relief, and international exercises. They are essential for maintaining a country's presence in international waters and can project power, deter threats, and support allies. The effectiveness of a naval fleet often depends on its training, technology, and coordination among its various components.
