The Arleigh Burke class of guided missile destroyers (DDGs) is the United States Navy's first class of destroyer built around the Aegis Combat System and the SPY-1D multifunction passive electronically scanned array radar. The class is named for Admiral Arleigh Burke, the most famous American destroyer officer of World War II, and later Chief of Naval Operations. The class leader, USS Arleigh Burke, was commissioned during Admiral Burke's lifetime.

These warships were designed as multimission destroyers to fit the antiaircraft warfare (AAW) role with their powerful Aegis radar and surface-to-air missiles; antisubmarine warfare (ASW), with their towed sonar array, anti-submarine rockets, and ASW helicopter; antisurface warfare (ASuW) with their Harpoon missile launcher; and strategic land strike role with their Tomahawk missiles. With upgrades to their AN/SPY-1 phased radar systems and their associated missile payloads as part of the Aegis Ballistic Missile Defense System, the ships of this class have also begun to demonstrate some promise as mobile antiballistic missile and anti-satellite weaponry platforms. Some versions of the class no longer have the towed sonar, or Harpoon missile launcher. Their hull and superstructure were designed to have a reduced radar cross section.
