DD(X) Multi-Mission Surface Combatant
Future Surface Combatant
The Navy's new DD(X) program is the centerpiece a family of three surface combatant ships, including a destroyer, a cruiser and a smaller craft for littoral operations. The DD(X) contract, to be awarded in 2005, could end up totaling $100 billion for some 70 warships in the DD(X) family: destroyers, cruisers, and a downsized seagoing killer called LCS, short for littoral combat ship. The cruiser and destroyer are expected to share a common hull design. The Littoral Combat Ship will most likely have an advanced hull designed for high speed and a shallow draft.
With resolution of the DD(X) bid protest, Northrop Grumman is on track to complete the DD(X) system design and associated engineering development models (EDM) by 2005. The scope and complexity of the design work, which includes development and integration of new hull and ship systems as well as advanced combat systems, is unprecedented for a U.S. Navy surface combatant. Northrop Grumman is responsible for the total ship system design, as well as development and testing of 11 EDMs.
While the DD(X) system design work is proceeding, the EDMs will be built and tested in parallel for key systems such as the integrated power system (IPS), the advanced gun system (AGS), and an integrated radar suite. Land-based and selected at-sea testing of the EDMs will be performed with the results engineered into the total ship system design. The second shipbuilder, Bath Iron Works, will perform DD(X) design and test activities as a subcontractor to Northrop Grumman, thus ensuring that both shipbuilders can compete on an equal basis for the next contractual phase, detail design and construction in FY05.
The Navy's fiscal 2005 budget requests funding for the first of eight new DDX destroyers by 2009, to be built by Northrop Grumman and Raytheon Co.
A return to the old tumblehome configuration, combined with wave piercing technology makes the Northrop Grumman DD(X) design as close to a submarine as a surface ship can be / with the lion's share of the structure actually underwater. The DD(X) design is described as 'wave-piercing,' which means that the designers have deliberately foregone the sort of buoyancy which tends to lift conventional ships over waves. Their motive is clear; they want to minimize ship motion because any motion presents an observing radar with opportunities to pick up the ship. Similarly they will want to minimize rolling motion, and they will have to accept that waves will often break over the ship's deck.
On 01 November 2001 the Navy announced that it would issue a revised Request for Proposal (RFP) for the Future Surface Combatant Program. Formerly known as DD 21, the program will now be called "DD(X)" to more accurately reflect the program purpose, which is to produce a family of advanced technology surface combatants, not a single ship class. Instead of building the large DD 21 destroyer, the Navy may use the advanced technology on a full range of ships, including a downsized destroyer, an even smaller warship to operate in coastal waters, and a larger cruiser. One of the concerns about the DD-21 was that it was much larger than the current DDG-51 Arleigh Burke-class destroyers. Another concern [reportedly of Deputy Defense Secretary Paul Wolfowitz] was that the Navy was investing too much in a ship primarily designed to accommodate the long-range Advanced Gun System. The House Appropriations Committee voted in October 2001 to cut funding for the DD-21 program by 75 percent. The Navy subsequently restructured the program, which was renamed the DD-X. The new "downsized" destroyer is slated to displace 12,000 tons, instead of the 16,000 tons planned for the DD 21.
The Navy plans to develop DD(X) over four years, procuring the first one in 2005 to enter service in 2011. The initial DD(X) was characterized as being a technology demonstrator for future surface combatants, rather than a design that would quickly enter serial production. Construction of the current Arleigh Burke-class of destroyers will be extended for three years -- from 2006 to 2009 -- as a result of the restructuring of the DD-21 program into the DD(X) program.
The DD(X) program is focused on developing 11 key Engineering Development Models (EDM) to demonstrate technologies critical to future warships. The 11 EDMs include electric drive and integrated power management systems; multi-function and volume search radar suites; the Advanced Gun System; and new hull design emphasizing efficiency at 30-knots sustained speed, mission payload growth capacity and stealth.
The DD(X) program will provide a baseline for spiral development of the DD(X) and the future cruiser or "CG(X)" with emphasis on common hullform and technology development. The Navy will use the advanced technology and networking capabilities from DD(X) and CG(X) in the development of the Littoral Combat Ship with the objective being a survivable, capable near-land platform to deal with threats of the 21st century. The intent is to innovatively combine the transformational technologies developed in the DD(X) program with the many ongoing R&D efforts involving mission focused surface ships to produce a state-of-the art surface combatant to defeat adversary attempts to deny access for US forces.
The revision of the program is based on the Navy's continued careful examination of DD21 as it reached the source selection milestone in Spring 2001. At that time, the Navy delayed the down-select decision between the two competing DD21 teams in order to take advantage of ongoing reviews being conducted in the Department of Defense, including the Quadrennial Defense Review. The Navy issued a revised request for proposal for DD(X) on 03 December 2001, and planned to down-select a single industry team to be the design agent and technology developer in Spring 2002.
Deputy Secretary of Defense Paul Wolfowitz approved the revised program focus and reaffirmed the Department's support for the Future Surface Combatant Program. "President Bush has made transformation of the Department of Defense a high priority. Through DD(X), the Navy has charted a course to transformation that will provide capability across the full spectrum of naval warfare. The Navy's strategy supports assured access to littoral regions and also develops the capability to defeat the air and missile defense threats the nation's naval forces will face in the future."
Under Secretary of Defense for Acquisition, Technology and Logistics E. C. "Pete" Aldridge stated that "the new program focus and new RFP will enable the Navy to fully leverage the great work already done by the two industry teams, continue risk mitigation measures and permit appropriate spiral development of technology and engineering to support a range of future surface ships to meet our Nation's maritime requirements well into the 21st Century," Aldridge said. "The DD(X) program will be the technology driver for the surface fleet of the future."
"With the approval of this strategy, the Navy has defined its surface combatant roadmap for the future in a manner which ensures all maritime missions can be accomplished. Through DD(X), we are taking a significant step toward providing improved combat capability for our Sailors and Marines," said Navy Secretary Gordon England.
Chief of Naval Operations Adm. Vern Clark said the DD(X) program reflects an awareness that effectively defeating future threats, while accomplishing naval missions, will require a range of naval capabilities and different surface platforms. "One size fits all will not work on the future battlefield," Clark said. "We must continue to exploit the robust R&D effort made on DD 21 even as we focus our research and technology funding of other approaches such as the Littoral Combat Ship concept."
Though the first class of ships will be nearly identical to the DD21 destroyer that has been on the drawing board for a few years, possible changes to future generations of ships won’t be stymied by having only one plan and design. After that class is designed, the next step will be to build a new ship that the Navy is calling ‘CG(X)’ that focuses more on air warfare, to include the Navy’s role in ballistic missile defense. DD-21 was focused on land-attack missions, which are very important, but that’s not the only thing the Navy needs to accomplish.
The change reopened the focus to keep other missions in mind and the Navy expects to see cost-saving benefits by being able to develop technology that can be used on a family of ship classes rather than duplicating our efforts and going through the same process each time.
The program’s revamping meant the Navy had to rebuild its profile for the new ships, and now does not know how many vessels will be built or at what cost. Under DD21, the Navy anticipated a production of 32 destroyers. It did not have a cost estimate because the builder and designer have not been selected. With DD21, the Navy divided planning into two teams. The Blue Team solicited shipbuilding plans from General Dynamics' Bath Iron Works subsidiary in Maine with technology from Lockheed Martin and General Dynamics. The Gold Team did the same, working with Ingalls Shipbuilding Company in Mississippi and parent Northrop Grumman Corp.
The DD(X) concept is to have watchstanders trained functionally across warfare areas who can be flexibly employed as the situation demands. This approach results in a more compact, flexible watch team, which requires fewer augmentations and which is designed to flexibly respond to a variety of tactical situations. Underpinning this concept is a strategy in which crewmembers will be highly trained across multiple warfare areas or maintenance tasks and advanced skills will apply across multiple disciplines with specialized skills only being used periodically. 1 Watchstations are manned in three sections, or 8-hour shifts, over the course of a day.
The DD(X) destroyer maintenance strategy focuses on allowing sailors to concentrate on war-fighting tasks and skills rather than on ship maintenance and preservation (i.e., “rust busting†skills). The DD(X) maintenance strategy envisions no organizational level repair conducted on the ship.
The DD(X) destroyer will employ extensive automated damage control systems, integrated with an optimally manned damage control organization to quickly suppress and extinguish fires and control their spread.
The Navy plans the DD(X) to be a multi-mission destroyer featuring a composite deckhouse and a Wave-Piercing Tumblehome Hull displacing about 14,000 tons. Optimized for the land-attack mission, it will have two Advanced Gun Systems (AGSs) with a combined magazine capacity of approximately 750 rounds of long-range land attack and conventional munitions. Each AGS will consist of a single-barrel 155mm gun supplied from an automated magazine. An Advanced Vertical Launch System (AVLS) with 80 cells will host Tomahawk Land Attack Missiles, Standard Missiles (SM2-MR) for local air defense, Evolved Seasparrow Missiles for engagement of both airborne and seaborne threats, and Vertical Launch Anti-Submarine Rockets for engagement of submarine threats. Two 40mm Close-In Gun Systems will enhance self-defense against air and surface threats.
DD(X)’s integrated power system will allow sharing of electrical power between propulsion motors and other electrical requirements such as combat system and auxiliary services. The Navy expects the new Dual Band Radar suite and the Integrated Undersea Warfare System to provide state-of-the-art battle space surveillance and advances in survivability and a total ship computing environment to allow a significant reduction in crew size. Introduction of additional new technology could reduce manning with each successive flight of the DD(X) spiral development.
