Template:Infobox Ship Class The Arleigh Burke class of guided missile destroyers, one of the destroyer classes of the United States Navy, is built around the Aegis combat system and the SPY-1D multi-function phased array radar. The first ship was commissioned on 4 July 1991. After the decommissioning of the last Spruance-class destroyer, USS Cushing, on September 21, 2005, the Arleigh Burke class ships became the U.S. Navy's only active destroyers.
The class is named for Admiral Arleigh "31-Knot" Burke, the most famous American destroyer officer of World War II. Admiral Burke was alive when the class leader was commissioned, and his words to the plankowners echo in the class' distinguished service to date: "This ship is built to fight; you had better know how."
The Japanese Maritime Self-Defense Force operates four modified Flight I vessels as the Kongo class. Three more will be commissioned by 2010, these will be upgraded to Flight IIA standard.
Characteristics
The Arleigh Burke class are among the largest and most powerful destroyers ever built, both larger and more heavily armed than many previous cruisers. (The larger Ticonderoga class were constructed on Spruance class hullforms, but are designated as cruisers.) The Arleigh Burke class breaks with previous American construction practices, by being built entirely of steel, rather than having a steel hull and aluminum superstructure. (An aluminum mast is used to reduce topweight). A 1975 fire aboard USS Belknap that gutted her aluminum superstructure and observation of battle damage to British ships during the Falklands War prompted the decision to employ a steel superstructure.
The Arleigh Burke class were the first U.S. warships designed with an air-filtration system against nuclear, biological and chemical warfare.[1]
Development
In 1980 the United States Navy initiated design studies with seven contractors. By 1983 the number of competitors had been reduced to three; Bath Iron Works, Todd Shipyards and Ingalls Shipbuilding.[1] On April 3 1985 Bath Iron Works received a US$321.9 million contract to build the first of class, USS Arleigh Burke.[2] The total cost of the first ship was put at US$1.1 billion, the other US$778 million being for the ship's weapons systems.[2]
The "Flight IIA Arleigh Burke" ships have several new features, which has led some to suggest that they be renamed the "Oscar Austin" class after the first ship, Oscar Austin (DDG-79). Among the changes are the addition of two hangars for ASW helicopters, and a new, longer 5-inch/62-caliber naval gun (fitted on Winston S. Churchill (DDG-81) and later ships). Later Flight IIA ships sport a modified funnel design that buries the funnels within the superstructure as a signature-reduction measure.
The United States Navy has begun a modernization program for the Arleigh Burke class aimed at improving the gun systems on the ships in an effort to address congressional concerns over the loss of the U.S. Iowa-class battleships. Among other things this modernization includes is the extension of the range of the 5in guns on the Flight I Arleigh Burke-class destroyers (USS Arleigh Burke to USS Ross) with extended range guided munitions (ERGMs) that would enable the ships to fire projectiles about 40 nautical miles inland.[3][4][5]
Modernization
The US Navy recently launched a modernization program that is designed to provide a comprehensive mid-life upgrade to ensure that the class remains effective. Reduced manning, increased mission effectiveness, and a reduced total cost of ownership are the goals of the modernization program. Modernization technologies will be integrated during new construction of DDG 111 and 112, then retrofitted into DDG Flight I and II ships during in service overhaul periods.[6]
Operational History
One Arleigh Burke class ship has been damaged by enemy action: Cole was damaged by an improvised explosive device delivered by suicide bombers on a boat in October 2000 in Aden, Yemen (see USS Cole bombing). The ship was repaired and returned to action in 2001.
Contractors
- Builders: General Dynamics, Bath Iron Works Division and Northrop Grumman Ship Systems
- SPY-1 Radar and Combat System Integrator: Lockheed Martin
Ships
DDG-112 will be the last of the class and is expected to be delivered in 2010.
