OVERVIEW: 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 multi-function phased 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.
They were designed as multi-role destroyers to fit the AAW (Anti-Aircraft Warfare) role with their powerful Aegis radar and anti-aircraft missiles; ASW (Anti-submarine warfare) role, with their towed sonar array, anti-submarine rockets, and ASW helicopter; ASUW (Anti-surface warfare) role with their Harpoon missile launcher; and strategic land strike role with their Tomahawk missiles. 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 class was commissioned on 4 July 1991. With the decommissioning of the last Spruance-class destroyer, Cushing, on 21 September 2005, the Arleigh Burke-class ships became the U.S. Navy's only active destroyers; the class has the longest production run for any postwar U.S. Navy surface combatant. The Arleigh Burke-class is planned to be the third most numerous class of destroyer to serve in the U.S. Navy, after the Fletcher and Gearing classes; besides the 62 vessels of this class (comprising 21 of Flight I, 7 of Flight II and 34 of Flight IIA) in service by 2013, up to a further 42 (of Flight III) have been envisaged.
With an overall length of 505 feet (154 m) to 509 feet (155 m), displacement ranging from 8,315 to 9,200 tons, and weaponry including over 90 missiles, the Arleigh Burke-class ships are larger and more heavily armed than most previous ships classified as guided missile cruisers.
DETAILS: The Arleigh Burke-class is among the largest destroyers built in the United States. Only the Spruance and Kidd classes were longer (563 ft). The Arleigh Burke-class are multi-mission ships with a combination of an advanced anti-submarine warfare system, land attack cruise missiles, ship-to-ship missiles, and advanced anti-aircraft missiles. The larger Ticonderoga-class ships were constructed on Spruance-class hullforms, but are designated as cruisers due to their radically different mission and weapons systems. The Arleigh Burke-class on the other hand were designed with a new, large, water-plane area-hull form characterized by a wide flaring bow which significantly improves sea-keeping ability. The hull form is designed to permit high speed in high sea states.
The Ticonderoga-class cruisers were deemed too expensive to continue building and too difficult to further upgrade. The angled rather than traditional vertical surfaces and the tripod mainmast of the Arleigh Burke design are stealth techniques, which make the ship more difficult to detect, in particular by anti-ship missiles.
Their Aegis radar differs from a traditional rotating radar that mechanically rotates 360 degrees for each "sweep" scan of the airspace which allows continual tracking of targets. The system's computer control also allows centralization of the previously separate tracking and targeting functions. The system is also resistant to electronic counter-measures. Their standalone Harpoon anti-ship missile launchers give them an anti-ship capability with a range in excess of 64 nm. The 5"/54 caliber Mark 45 gun, in conjunction with the Mark 34 Gun Weapon System, is an anti-ship weapon which can also be used for close-in air contacts or to support forces ashore with Naval Gun-Fire Support (NGF), with a range of up to 20 miles and capable of firing 20 rounds per minute. The class's RIM-7 Sea Sparrow missiles provide point defense against missiles and aircraft while the Standard Missile provides area anti-aircraft defense, additionally the ship has an electronics warfare suite that provides passive detection and decoy countermeasures.
The class's Light Airborne Multipurpose System, or LAMPS helicopter system improves the ship's capabilities against submarines and surface ships, a helicopter able to serve as a platform to monitor submarines and surface ships, and launch torpedoes and missiles against them, as well as being able to support ground assaults with machine guns and Hellfire anti-armor guided missiles. The helicopters also serve in a utility role, able to perform ship replenishment, search and rescue, medical evacuation, communications relay, and naval gunfire spotting and controlling.
Arleigh Burke-class destroyers have many combat systems. Burkes have the Navy's latest anti-submarine combat system with active sonar, a towed sonar array, and anti-submarine rockets. They support strategic land strikes with their VLS launched Tomahawks. They are able to detect anti-ship mines at a range of 1400 yards.
So vital has the Aegis Ballistic Missile Defense System (BMD) role of the class become that all ships of the class are being updated with BMD capability. Burke production is being restarted in place of additional Zumwalt-class destroyers.
