Destroyers are fast, maneuverable warships designed primarily for escorting larger vessels in a fleet. They are equipped with a variety of weapons and advanced technology to protect against threats such as submarines, aircraft, and missile attacks. Their speed and agility make them essential for naval operations, allowing them to respond quickly to emerging threats. Typically, destroyers are armed with guided missiles, torpedoes, and naval guns, making them versatile in combat. They play a crucial role in modern naval warfare, often serving as the backbone of a navy's surface fleet. Notable classes of destroyers include the Arleigh Burke-class and Type 45 destroyers.
