destroyers

Destroyers are fast, maneuverable warships built to protect larger vessels and deter or defeat small, agile threats such as torpedo boats, aircraft, and submarines. The term arose in the early 20th century with "torpedo boat destroyers" in the Royal Navy; the shorter form "destroyer" later became standard as the class grew beyond its original purpose.

Traditionally, destroyers performed escort duties for fleets and convoys and conducted anti-submarine and anti-air operations. They also engaged surface targets and provided fleet command support. Modern destroyers are multi mission platforms that integrate propulsion, sensors, and weapons to operate independently or as part of carrier or surface action groups.

Armament and sensors have evolved from guns and torpedoes to multi‑purpose missiles and advanced radar, sonar, and electronic warfare systems. Many destroyers employ vertical launch systems, anti-ship and anti-air missiles, naval guns, and helicopters or unmanned aircraft for extended reach and ASW.

Several navies deploy modern destroyers, including the United States with Arleigh Burke-class ships (and newer classes), the United Kingdom with Type 45 destroyers, and others around the world. The designation "destroyer" remains a broad label for fast, multi‑role escort ships, even as naval classifications vary by country.
