ARLEIGH BURKE CLASS DESTROYER
Arleigh Burke class of guided missile destroyers (DDGs) is a United States Navy class of destroyer built around the Aegis Combat System and the SPY-1D multifunction passive electronically scanned array radar.
Arleigh Burke class is named for Admiral Arleigh Burke, an American destroyer officer in World War II, and later Chief of Naval Operations. The lead ship, USS Arleigh Burke, was commissioned during Admiral Burke’s lifetime.
Arleigh Burke class were designed as multimission destroyers, able to fulfill the strategic land strike role with Tomahawk missiles; antiaircraft warfare (AAW) role with powerful Aegis radar and surface-to-air missiles; antisubmarine warfare (ASW) with towed sonar array, anti-submarine rockets, and ASW helicopter; and antisurface warfare (ASuW) with Harpoon missile launcher. 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, operating on 15 ships as of March 2009. 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.
The first ship of the Arleigh Burke class was commissioned on 4 July 1991.
With an overall length of 505 to 509.5 feet (153.9 to 155.3 m), displacement ranging from 8,230 to 9,700 tons, and weaponry including over 90 missiles, the Arleigh Burke class are larger and more heavily armed than most previous ships classified as guided missile cruisers.
