The Arleigh Burke-class destroyers are the US Navy’s most powerful destroyer fleet. These highly-capable, multi-mission ships conduct a variety of operations, from peacetime presence to national security.
The DDG 51 Class design is captured in a three-dimensional model and interfaced with the Computer-Aided Manufacturing (CAM) systems, in which numerically-controlled manufacturing equipment cut plate and bend pipe. Ingalls Shipbuilding uses modular construction techniques pioneered by the shipyard in the 1970s and refined over the years to maximize shipyard throughput. During the construction of a DDG 51 destroyer, 72 structural assemblies (units) are integrated, forming 21 grand blocks. These grand blocks are integrated, creating the ship’s hull modules 1, 2 and 3. The deckhouse is landed (module 4), piping systems installed, cable routed, equipment connected and systems readied for test. The ship is moved to a drydock and launched in a 12-hour time period. Final outfitting and test is completed pier side.
Arleigh Burke-class destroyers include 322 miles of cable, 185,000 feet of pipe and enough hull insulation (450,000 square feet) to cover the roof of the Superdome in New Orleans. Armor is placed around vital combat systems and machinery spaces. Acoustic, infrared and radar signatures have been reduced, and vital shipboard systems are hardened against electromagnetic pulse and over-pressure damage. In addition, a Collective Protection System guards against nuclear, chemical and biological agents.
Ingalls Shipbuilding Wins U.S Navy Contract to Build Five DDG 51 Destroyers
Ingalls Shipbuilding has been awarded a fixed-price incentive, multiyear contract for construction of five Arleigh Burke-class destroyers (DDG 51s) for the U.S. Navy. The contract, announced today, has a total value of $3.33 billion and includes options for engineering change proposals, design budgeting requirements and post-delivery availabilities, which, if exercised, would bring the cumulative value of the contract to approximately $3.39 billion.
