It was released in Europe on February 29, 2008 and in North America on March 24, 2008. With its guns neutered, its role as a primary anti-submarine-warfare asset in question, its anti-air-warfare capabilities inferior to those of our current workhorse, the Arleigh Burke-class destroyers, and its stealth not nearly as advantageous as advertised, the Zumwalt seems to be a ship without a mission. While underway during the spring of 2019, USS Zumwalt sailed through a storm causing sea state six conditions off the coast of Alaska. [24], Northrop Grumman was awarded a $90M contract modification for materials and production planning on 13 November 2007. At that time, the first DDG-1000 destroyer was expected to cost $3.5 billion, the second approximately $2.5 billion, and the third even less. [109], It is possible for the Zumwalt-class destroyers to get the more limited BMD hardware and software modifications that would allow them using their existing SPY-3 radar and Cooperative Engagement Capability to utilize the SM-3 missile and have a BMD capability similar to the BMD-capable Ticonderoga-class cruisers and Burke-class Flight IIa destroyers. [73][74][75], Lyndon B. Johnson, the last Zumwalt, is being considered for the installation of a railgun in place of one of the 155 mm naval guns after the ship is built. Originally, the navy proposed building 32 next-generation destroyers, reduced that to 24, then to 7, and finally to 3, in order to make the program affordable. "Root Cause Analyses of Nunn-McCurdy Breaches -- Zumwalt-Class Destroyer, Joint Strike Fighter, Longbow Apache, and Wideband Global Satellite," Rand Corporation (2011); see Vol. [66] Ammunition, food, and other stores are all mounted in containers able to be struck below to magazine/storage areas by an automated cargo handling system. The Navy is monitoring research on alternative munitions, but since the AGS was tailor-made to use the LRLAP, modifications will be needed to accept different shells, which is unlikely to happen by the time the first Zumwalt vessel enters operational service in 2018, leaving it unable to fulfill the naval gunfire support role it was designed for. [18] The class is designed to require a smaller crew and to be less expensive to operate than comparable warships. Originally, the Navy had hoped to build 32 destroyers. [citation needed]. [14], With the arrival of the German campaign, players gain control over additional strategic resources other than their own submarines. The PMM was considered to be another technology leap and was the cause of some concern (along with the radar system) from Congress. Like its predecessor Silent Hunter 3, the simulation features a dynamic campaign. The Zumwalt-class destroyer is a class of three United States Navy guided missile destroyers designed as multi-mission stealth ships with a focus on land attack. On October 31, 2007 Ubisoft announced The U-Boat Missions add-on to Silent Hunter 4. [36][110], Zumwalt PLAS cells can launch the SM-2 Standard missile, but the ships have no requirement for ballistic missile defense. From then to 2010, various analysis efforts were conducted to assess potential cost-saving alternatives. However, if the Air Missile Defense Radar is adopted in common on both the Flight III Burkes and the Zumwalts and if they were both upgraded to the same combat system then the only limitation of the Zumwalts in this role would be their limited missile magazines. In April 2006, the Navy announced plans to name the first ship of the class Zumwalt after former Chief of Naval Operations Admiral Elmo R. "Bud" Zumwalt Jr.[42] The vessel's hull number would be DDG-1000, which abandoned the guided missile destroyer sequence used by the Arleigh Burke-class destroyers (DDG-51–), and continued the previous "gun destroyer" sequence from the last of the Spruance class, Hayler (DD-997). First 18 frigates of the class lack the important variable depth sonar (VDS). The Zumwalt-class has a wave-piercing tumblehome hull form whose sides slope inward above the waterline, which dramatically reduces RCS by returning much less energy than a conventional flare hull form. The game gives players various mission objectives and unique rewards, and attempts to make each campaign a unique experience. And in view of recent intelligence that China is developing targetable anti-ship ballistic missiles based on the DF-21,[102][103] this could be a fatal flaw. "[107] While the Flight III design and costs have been studied by the navy, there is very little reliable data available on what the cost would be to modify a DDG-1000–class ship to provide a BMD capability. The Arleigh Burke-class ships have BMD systems with their Lockheed-Martin AEGIS tracking and targeting software,[101] unlike the DDG-1000's Raytheon TSCE-I targeting and tracking software,[93] which does not, as it is not yet complete, so while the DDG-1000, with its TSCE-I combat system, does have the SM-2/SM-3 missile system installed, it does not yet have the BMD/IAMD upgrade planned for the derived CG(X). [96] The network allows a seamless integration of all on-board systems, e.g. Halon/Nitrogen dump systems are preferred but do not work when space has been compromised by a hull breach. The game received "generally favorable reviews" according to video game review aggregator Metacritic. "[116] The Navy decided not to use a tumblehome hull in the CG(X) cruiser before the program was canceled, which may suggest that there were concerns regarding Zumwalt's sea-keeping abilities. In April 2016, the total program cost was $22.5 billion. The test indicated that the Zumwalt class possesses greater stability compared to typical hull forms. [65] The tumblehome has been reintroduced in the 21st century to reduce the radar return of the hull. [citation needed], The composite deckhouse encloses much of the sensors and electronics. The ESSM is considered a point defense weapon not generally used for fleet area defense. A primary goal for DD 21 was to provide sea-based fire support for on-shore troops, as part of the force mix that would replace the retiring Iowa-class battleships as mandated by Congress. The class's role was to provide Naval Surface Fire Support, which requires the ship to be in typically crowded near-shore waters, where such large and distinctive ships can be tracked visually, and any surface ship becomes non-stealthy when it begins firing guns or missiles. [29], On 19 August 2008, Secretary Winter was reported as saying that a third Zumwalt would be built at Bath Iron Works, citing concerns about maintaining shipbuilding capacity. This is feasible because the installed Rolls-Royce turbine generators are capable of producing 78 megawatts (105,000 hp), enough for the electrically powered weapon. The boat hangar's stern location meets high sea state requirements for boat operations. [19] However, this was increased to two ships by the 2007 appropriations bill[24] approved in September 2006, which allotted US$2.568 billion to the DDG-1000 program. [84], The Dual Band Radar in its entirety (SPY-3 & SPY-4) is to be installed only on the Gerald R. Ford-class aircraft carrier Gerald R. Ford. The Zumwalt-class destroyer is not an Aegis system. [36][81] This system is thought to provide high detection and excellent anti-jamming capabilities, particularly when used in conjunction with the Cooperative Engagement Capability (CEC). [36] In April 2016, the U.S. It uses instead the class-unique Total Ship Computing Environment Infrastructure (TSCEI) integrated mission system. DDG-1001 would be named for Master-at-Arms 2nd Class Michael A. Monsoor, the second Navy SEAL to receive the Medal of Honor in the Global War on Terror, the navy announced on 29 October 2008. [80] A 2005 report by Congress' investigative arm, the Government Accountability Office (GAO), questioned that the technology leap for the Dual Band Radar would be too much. [66][92], The Total Ship Computing Environment Infrastructure (TSCEI) is based on General Electric Fanuc Embedded Systems' PPC7A and PPC7D single-board computers[93] running LynuxWorks' LynxOS RTOS. The America-class amphibious assault ships starting with LHA-8 and the planned LX(R)-class amphibious warfare ships will also have this radar. On 22 February 2009 James "Ace" Lyons, the former commander in chief of the U.S. Pacific Fleet, stated that the DDG-1000's technology was essential to a future "boost phase anti-ballistic missile intercept capability". [41], The construction timetable in July 2008 was:[42], The Navy planned for Zumwalt to reach initial operating capability (IOC) in 2016. The inverted bow is designed to cut through waves rather than ride over them. Using a Multiple Rounds Simultaneous Impact (MRSI) firing tactic the combined firepower from a pair of turrets gives each Zumwalt-class destroyer initial strike firepower equivalent to 12 conventional M198 field guns. In summary, the committee is concerned that the navy has foregone the long range fire support capability of the battleship, has given little cause for optimism with regard to meeting near-term developmental objectives, and appears unrealistic in planning to support expeditionary warfare in the mid-term. This weapon system has a range of 83 nautical miles (154 km). It places the player in command of an U.S. Navy submarine during World War II and takes place in the Pacific theater.The game allows players a variety of … A hull-mounted sonar; OQR-3 towed array sonar; An OPS-20C surface search radar. [37] On 14 February 2008, Bath Iron Works was awarded a contract for the construction of Zumwalt (DDG-1000), and Northrop Grumman Shipbuilding was awarded a contract for the construction of Michael Monsoor (DDG-1001), at a cost of $1.4 billion each. [29] The lack of anti-ballistic missile capability may represent a lack of compatibility with SM-2/SM-3. On the other hand, these very differences will force time and cost penalties from design and construction changes if the program wishes to "design AIM out" …[90], The system reduces the ship's thermal and sound signature. [91], Automation reduces crew size on these ships: the Zumwalt-class destroyer's minimum complement is 130, less than half of needed by "similar warships". The Zumwalt-class destroyer is a class of three United States Navy guided missile destroyers designed as multi-mission stealth ships with a focus on land attack. On the DDG 1000, with the waves coming at you from behind, when a ship pitches down, it can lose transverse stability as the stern comes out of the water – and basically, roll over. The Zumwalt class was intended to provide naval surface fire support (NSFS) using the AGS and additional land attack using Tomahawk missiles from its PVLS launchers. [26] Subsequently, Chief of Naval Operations Gary Roughead cited the need to provide area air defense and specific new threats such as ballistic missiles and the possession of anti-ship missiles by groups such as Hezbollah. Water sleeting along the sides, along with passive cool air induction in the mack, reduces infrared signature. Significant software modifications are required to support the ICWI, transmit and receive link messages to the missiles. [50], As of January 2009, the Government Accountability Office (GAO) found that four out of 12 of the critical technologies in the ship's design were fully mature. He concludes: The Zumwalt is an unmitigated disaster. The system is "integrated" because the turbo-generators provide electrical power for all ship systems, not just the drive motors. The technology array allows sailors to monitor multiple weapons systems or sensors, saving manpower, and allowing it to be steered from the ops center. [citation needed]. [72], The "Zumwalts" use an Integrated Power System (IPS), which is a modern version of a turbo-electric drive system. In April 2007, naval architect Ken Brower said, "As a ship pitches and heaves at sea, if you have tumblehome instead of a flare, you have no righting energy to make the ship come back up. Both Northrop Grumman Ship Systems and General Dynamics Bath Iron Works shared dual-lead for the hull, mechanical, and electrical detailed design. Raytheon's X-band, active-array SPY-3 Multi-Function Radar (MFR) offers superior medium to high altitude performance over other radar bands, and its pencil beams give it an excellent ability to focus in on targets. The appearance has been compared to that of the historic USS Monitor[15] and her famous antagonist CSS Virginia.[16][14]. [39] Construction on the second ship of the class, Michael Monsoor, began in March 2010. Forced to surface by Allied warships, the crew of U-505 abandoned ship. "Navy's stealth destroyer designed for the video gamer generation", "Zumwalt Class Destroyer Integrated Composite Deckhouse & Apertures (IDHA)", "Will DDG 1000 Produce Any Ships at All? The second ship, Michael Monsoor, was commissioned in 2019, and the third ship, Lyndon B. Johnson (DDG-1002), is to reach IOC in 2021.[48]. It was originally put forth in modern steel battleship designs by the French shipyard Forges et Chantiers de la Méditerranée in La Seyne, Toulon. [2], In late 2005, the program entered the detailed design and integration phase, for which Raytheon was the Mission Systems Integrator. Zumwalt has Converteam's Advanced Induction Motors (AIM), rather than DRS Technologies' Permanent Magnet-Synchronous Motors (PMM). As costs overran estimates, the quantity was reduced to 24, then to 7, and finally to 3, significantly increasing the cost per ship to $4.24 billion ($7.5 billion including R&D costs)[1][19][20][2] and well exceeding the per-unit cost of a nuclear-powered Virginia-class submarine ($2.688 billion). Almost every major defense contractor (including Lockheed Martin, Northrop Grumman Sperry Marine, L-3 Communications) and subcontractors from nearly every state in the U.S. were involved to some extent in this project, which was the largest single line item in the Navy's budget. Radar mostly works on targets that decide to slow down and sit still in their smoke. The capture of the German submarine U-505 took place off the coast of Africa on June 4, 1944 during World War II (1939-1945). [56] In 2008, Defense News reported there had been problems sealing the composite construction panels of this area; Northrop Grumman denied this. [104], In 2010, the Congressional Research Service reported that the DDG-1000 cannot currently be used for BMD because the BMD role was deferred to the DDG-1000 derived CG(X) program (the DDG's had the strike role, the CG had the BMD role, but they shared both the SM3 missile, and the TSCE-I), the proposed radar of the CG(X) was much larger (22')[105] and used much more energy and cooling capacity than the DDG-1000's. The class has an integrated power system that can send electricity from its turbo-generators to the electric drive motors or weapons, the Total Ship Computing Environment Infrastructure (TSCEI),[17] automated fire-fighting systems, and automated piping rupture isolation. )[5] driving Curtiss-Wright electric generators. [87], Although Zumwalt ships have an integrated suite of undersea sensors and a multi-function towed array, they are not equipped with onboard torpedo tubes, so they rely on their helicopters or ASROC missiles to destroy submarines that the sonar picks up. Clearly it is not a good fit as a frontline warship. Navy Secretary Donald Winter said on 4 September that "Making certain that we have – I'll just say, a destroyer – in the '09 budget is more important than whether that’s a DDG 1000 or a DDG 51". The downside is that AIM technology has a heavier motor, requires more space, requires a "separate controller" to be developed to meet noise requirements, and produces one-third the amount of voltage. It is a multi-role class that was designed for secondary roles of surface warfare and anti-aircraft warfare and originally designed with a primary role of naval gunfire support. [30] House Defense Appropriations Subcommittee Chairman John Murtha said on 23 September 2008 that he had agreed to partial funding of the third DDG-1000 in the 2009 Defense authorization bill. [31], A 26 January 2009 memo from John Young, the US Department of Defense's (DoD) top acquisition official, stated that the per ship price for the Zumwalt-class destroyers had reached $5.964 billion, 81 percent over the Navy's original estimate used in proposing the program, resulting in a breach of the Nunn–McCurdy Amendment, requiring the Navy to re-certify and re-justify the program to Congress or to cancel its production. On 23 April 1918, British naval forces attacked U-boat bases at Ostend and Zeebrugge. 3 via, RIM-162 Evolved Sea Sparrow Missiles (ESSM), United States battleship retirement debate, Naval Surface Warfare Center Carderock Division, "GAO-15-342SP DEFENSE ACQUISITIONS Assessments of Selected Weapon Programs", "Navy Requires $450 Million More to Complete Zumwalt-Class Due to Shipyard Performance", "Historic And Cutting Edge USS Zumwalt Commissioned in Baltimore", CRS RL32109 Navy DDG-51 and DDG-1000 Destroyer Programs: Background and Issues for Congress, "No New Round Planned For Zumwalt Destroyer Gun System; Navy Monitoring Industry", https://news.usni.org/2016/11/07/navy-planning-not-buying-lrlap-rounds, Navy Swaps Out Anti-Swarm Boat Guns on DDG-1000s, "New Requirements for DDG-1000 Focus on Surface Strike", "The Navy's Battlewagon of the 21st Century", "New Zumwalt-Class Destroyer Is Not Your Father's Tin Can", "Navy Approves Raytheon's Zumwalt Total Ship Computing Environment Infrastructure", "Electromagnetic Railgun – A "Navy After Next" Game Changer", "Cutting-edge Navy warship being built in Maine", "RL32418, Navy Virginia (SSN-774) Class Attack Submarine Procurement: Background and Issues for Congress", http://www.rand.org/pubs/monographs/MG1171z1.html, "Navy: No Need to Add DDG 1000s After All", "Pentagon's Unwanted Projects in Earmarks", "Roughead pushes for littoral combat ship", "Troubled DDG 1000 faces shipyard problems", "Negotiators agree to buy more F-22s, Zumwalt destroyers", "General Dynamics To Build New Destroyer", "Navy DDG-51 and DDG-1000 Destroyer Programs: Background and Issues for Congress", "U.S. Navy Awards Northrop Grumman $90 Million Long-Lead Material Contract for DDG 1000", "Navy Awards Contracts for Zumwalt Class Destroyers", "America's Newest and Deadliest Destroyer Has Finally Set Sail", "GAO-08-804, Defense Acquisitions: Cost to Deliver Zumwalt-Class Destroyers Likely to Exceed Budget", "First Zumwalt-Class Destroyer to Join U.S. Navy Fleet by late 2014", "Raytheon awarded $75 million for DDG 1000 Zumwalt class Destroyer program", "U.S. Navy Christened USS Zumwalt (DDG 1000), New Class of Destroyer", "Future Zumwalt class Destroyer USS Michael Monsoor (DDG 1001) Deckhouse Successfully Integrated", "General Dynamics Bath Iron Works Awarded $212 Million for DDG 1002 Deckhouse, Hangar and Launch-System Modules", "DDG 1000 Preps for Heavy Weather Trials", "Navy to name newest destroyer after SEAL who died in Iraq", "Navy Names Zumwalt Class Destroyer USS Lyndon B.

[103] However, the tumblehome hull proved seaworthy in a 1/4-scale test of the hull design named Sea Jet.[117]. An alternate twin pod arrangement was rejected as the ramifications of pod drives would require too much development and validation cost to the vessel. The navy concluded that developing IAMD software and hardware specifically for TSCE would be more expensive and present higher risk. [119][verification needed], Est combined Procurement cost for 3 ships, Section 1011 of the National Defense Authorization Act for Fiscal Year 1996 (Public Law 104-106; 110 Stat. [63], The Zumwalt-class destroyer reintroduces the tumblehome hull form, a hull form not seen to this extent since the Russo-Japanese War in 1905. The discovery came as a flotilla of warships, helicopters and divers were deployed off the coast of the sprawling city Sunday. The DDX proposed to use permanent-magnet motors (PMMs) within the hull, an approach that was abandoned in favor of a more conventional induction motor.

[57], The U.S. Navy solicited bids for a lower cost steel deckhouse as an option for DDG-1002, the last Zumwalt destroyer, in January 2013. The Battle of Jutland was to be the only major naval battle of the First World War, and the most significant encounter between warships of the dreadnought era. The AMDR has continued in fully funded development for installation on the DDG-51 Flight III ships. [9] LRLAP procurement was cancelled, rendering the guns unusable,[9] so the Navy re-purposed the ships for surface warfare. It places the player in command of an U.S. Navy submarine during World War II and takes place in the Pacific theater. The original "shelf version" of the game was never updated; all game versions, including those downloadable on Steam, continue to depict fictional awards in lieu of actual United States combat decorations. [66][67] The stability of this hull form in high sea states has caused debate among naval architects, with some charging that "with the waves coming at you from behind, when a ship pitches down, it can lose transverse stability as the stern comes out of the water—and basically roll over. The game allows players a variety of play modes including career, single war patrol and single battle engagements. [66], Water spray or mist systems are proposed for deployment in the Zumwalt-class destroyer, but the electronic spaces remain problematic to the designers. Sea Jet was operated on Lake Pend Oreille, where it was used for test and demonstration of various technologies. [106], The study that showed a cost benefit to building Flight III Arleigh Burke-class destroyer with enhanced radars instead of adding BMD to the Zumwalt-class destroyers assumed very limited changes from the Flight II to the Flight III Burkes. [94] These are contained in 16 shock, vibration, and electromagnetic protected Electronic Modular Enclosures. A study to place the AMDR on a DDG-1000 hull was done with the 22-foot (6.7 m) aperture primarily for Ballistic Missile Defense (BMD) purposes. The expansion focuses on the German U-boat campaign in the Indian Ocean (the Monsun Gruppe). During the previous contract, development and testing of 11 Engineering Development Models (EDMs) took place: Advanced Gun System, Autonomic Fire Suppression System, Dual Band Radar [X-band and L-band], Infrared, Integrated Deckhouse & Apertures, Integrated Power System, Integrated Undersea Warfare, Peripheral Vertical Launch System, Total Ship Computing Environment Infrastructure (TSCEI), Tumblehome Hull Form. Servers supported up to eight players and let them choose from several scripted and generated missions. [85], AMDR (Air and Missile Defense Radar) was originally proposed to be installed in the hull of DDG-1000 type under the CG(X) program. 421). Navy officials stated that Aegis had proven some BMD capability and was widely used across the fleet, and that the navy wanted to leverage the investments it had made over the years in this combat system, especially in its current development of a version that provides a new, limited IAMD capability. GAO Assessments of Major Weapon Programs. The class design emerged from the DD-21 "land … So while the DDG-51 platform and the DDG-1000 platform are both SM-2/SM-3 capable, as a legacy of the Aegis Ballistic Missile Defense System only the DDG-51 with the Aegis combat system is BMD capable, although the DDG-1000's TSCE-I combat system had both BMD and IAMD upgrades planned. In late December 2005, the House and Senate agreed to continue funding the program. The world in photos: Feb 1 - 7. [55], A dual-band sonar controlled by a highly automated computer system will be used to detect mines and submarines. Following a 2012 assessment using the latest gun and munition effectiveness information, it was concluded that the Mk 46 30 mm (1.2 in) Gun System was more effective than the Mk 110 with increased capability, reduced weight, and significant cost avoidance. The design was shifted to the AIM system in February 2005 in order to meet scheduled milestones; PMM technical issues were subsequently fixed, but the program has moved on. However, due to cost growth, the CG(X) program was canceled. [12] The ship is designed around its two Advanced Gun Systems, their turrets and magazines, and unique Long Range Land Attack Projectile (LRLAP) ammunition. "[55], The acoustic signature is comparable to that of the Los Angeles-class submarines. [66][78], Two spots are available on a large aviation deck with a hangar capable of housing two full size SH-60 helicopters. Lawmakers and others questioned whether the Zumwalt-class costs too much and whether it provides the capabilities that the military needs. The design concept for the Zumwalt class developed from the "Land Attack Destroyer (DD 21)" development effort. Naval Institute stated "the original design of the ship would have had a much smaller RCS, but cost considerations prompted the Navy over the last several years to make the trades in increasing RCS to save money..."[61], To improve detection in non-combat situations by other vessels, such as traversing busy shipping channels or operating in inclement weather, the Navy is testing adding onboard reflectors to improve the design's radar visibility. The system provides much more available electrical power than is available in other types of ship. "[63] Fredenburg went on to detail problems relating to the skyrocketing costs, lack of accountability, unrealistic goals, a flawed concept of operations, the perils of designing a warship around stealth, and the failure of the Advanced Gun System. [111] However, the final DDG-1000 design provides only 80 cells. It is, however, not reported if the CEC system will be installed on the Zumwalt-class destroyers upon commissioning, but it is scheduled for eventual incorporation in the ship type. In 2005, the Congressional Budget Office estimated the acquisition cost of a DD(X) at $3.8 billion to $4 billion in 2007 dollars, $1.1 billion more than the navy's estimate. [2][21][22] The dramatic per-unit cost increases eventually triggered a Nunn–McCurdy Amendment breach and cancellation of further production,[23] so the Navy reverted to building more Arleigh Burke destroyers.
