The Zumwalt, the first of three ships in the class, will cost at least $4.4 billion. [41] The keel for the first Zumwalt-class destroyer was laid on 17 November 2011. “The ship has a radar cross section one-fiftieth of its previous classes of destroyers,” said its captain, James Kirk. The appearance has been compared to that of the historic USS Monitor[16] and her famous antagonist CSS Virginia.[17][15]. The Advanced Electric Ship Demonstrator (AESD) Sea Jet funded by the Office of Naval Research (ONR) is a 133-foot (40-meter) vessel located at the Naval Surface Warfare Center Carderock Division, Acoustic Research Detachment in Bayview, Idaho. NAVSEA officially stated that the … [76][77], The Peripheral Vertical Launch System (PVLS) is an attempt to avoid intrusion into the prized center space of the hull while reducing the risk of loss of the entire missile battery or of the ship in a magazine explosion. [citation needed], The composite deckhouse encloses much of the sensors and electronics.

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 boat hangar's stern location meets high sea state requirements for boat operations. In 2009, Defense Secretary Robert Gates said that the Department of Defense’s budget would end the production of [72], The "Zumwalts" use an Integrated Power System (IPS), which is a modern version of a Turbo-electric drive system. 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. ABOARD THE USS ZUMWALT -- There has never been a Navy destroyer like this -- never one that looked like this and never one that cost so much. [56] The fully automated storage system has room for up to 750 rounds. [26], On 31 July 2008, U.S. Navy acquisition officials told Congress that the service needed to purchase more Arleigh Burke-class destroyers, and no longer needed the next-generation DDG-1000 class,[27] Only the two approved destroyers would be built. Lawmakers and others questioned whether the Zumwalt-class costs too much and whether it provides the capabilities that the military needs. It’s now up to the ship’s crew to make the Navy’s newest destroyer pay off. Her home port is San Diego, California. © 2016 CBS Interactive Inc. All Rights Reserved. GAO Assessments of Major Weapon Programs. The guided-missile destroyer USS Zumwalt (DDG 1000) arrives at its new homeport in San Diego on Dec. 8, 2016 (U.S. Navy/Petty Officer 3rd Class Emiline L. M. Senn) This is deeply unsurprising. The previously undisclosed delay for the first ship, the $7.8 billion USS Zumwalt, was confirmed by Colleen O’Rourke, a navy spokeswoman, via email. [31] 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. The ship looks like nothing ever built at Bath Iron Works. However, at that date, funding had yet to be authorized by Congress. The design of the PVLS directs the force of any explosion outward rather than into the ship. "[56], The acoustic signature is comparable to that of the Los Angeles-class submarines. 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. [29] The mooted structural problems have not been discussed in public. On 31 July 2008, Vice Admiral Barry McCullough (Deputy Chief of Naval Operations for Integration of Resources and Capabilities) and Allison Stiller (Deputy Assistant Secretary of the Navy for Ship Programs) stated that "the DDG 1000 cannot perform area air defense; specifically, it cannot successfully employ the Standard Missile-2 (SM-2), SM-3 or SM-6 and is incapable of conducting Ballistic Missile Defense. [64] On the downside, the tumblehome battleships leaked – partly due to their riveted construction – and could be unstable, especially when turning at high speed. [37] Due to the SPY-4 removal, the SPY-3 radar is to have software modifications so as to perform a volume search functionality. 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. The Zumwalt cost more than $4.4bn and was commissioned in October in Maryland. The US Navy on Saturday christened the first of its newest class of destroyers – the more than $3 billion (£1.8 billion), 610-foot (186-metre)-long USS Zumwalt. [42], The construction timetable in July 2008 was:[43], The Navy planned for Zumwalt to reach initial operating capability (IOC) in 2016. [84], The SPY 3 had to be reprogrammed to do the volume search that the SPY-4 was supposed to have performed. With the development of the AMDR (Air and Missile Defense Radar), it seems unlikely the DBR is to be installed on any other platforms, as it is on the DDG-1000 class, or in total, as it is on Gerald R. Ford. The peripheral vertical launch system (PVLS) is capable of accommodating all Standard missile types. 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". The final cost of the Zumwalt is expected to be at least $4.4bn. 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..."[62], 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. [10] LRLAP procurement was cancelled, rendering the guns unusable,[10] so the Navy re-purposed the ships for surface warfare. [61] The U.S. 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. [citation needed]. Among the new technologies are automated gun mounts. In November 2016, BAE Systems was awarded a $192 million contract to deliver the combat system for Zumwalt and its sister ship the Michael Monsoor. The Zumwalt has a huge amount of space for a Navy warship, which allows the crew to bring the ammunition in on a forklift, and an elevator takes the ammunition down to the magazine and the rounds are then automatically loaded into the gun. Production of the USS Zumwalt (DDG 1000), the first of the class, began at Bath Iron Works (BIW) on February 11, 2009. He concludes: The Zumwalt is an unmitigated disaster. [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. As deployed, the Zumwalt class cannot provide NSFS, since there is no ammunition available that is compatible with the AGS. Overall, the destroyer's angular build makes it "50 times harder to spot on radar than an ordinary destroyer. However, the class was gradually scaled back to three hulls due to budgetary considerations; the cost per round for a correspondingly smaller quantity of ammunition went up to nearly $1m per shot. Water sleeting along the sides, along with passive cool air induction in the mack, reduces infrared signature. This weapon system has a range of 83 nautical miles (154 km). The tubes are long and wide enough to incorporate future interceptors, and although the ship was designed primarily for littoral dominance and land attack, Raytheon contended that they could become BMD-capable with few modifications.[72]. [20] However, this was increased to two ships by the 2007 appropriations bill[25] approved in September 2006, which allotted US$2.568 billion to the DDG-1000 program. Zumwalt is the lead ship of a class of next-generation multi-mission destroyers designed to strengthen naval power from the sea. The initial funding allocation was included in the National Defense Authorization Act of 2007. It also suffered a leak in its propulsion system before it was commissioned. SPY-3 will be the primary radar used for missile engagements. Copyright © 2020 CBS Interactive Inc.All rights reserved. [37][110], Zumwalt PLAS cells can launch the SM-2 Standard missile, but the ships have no requirement for ballistic missile defense. Among the first technologies tested was an underwater discharge waterjet from Rolls-Royce Naval Marine, Inc. called AWJ-21. [113] It has not been publicly stated if the TSCE will be modified to support the Standard missile or the ballistic missile defense mission. WASHINGTON: Under intense budget pressure, a Pentagon cost-cutting team is pushing the Navy to cancel its third and last Zumwalt-class destroyer, the … [72] In November 2016, the Navy moved to cancel procurement of the LRLAP, citing per-shell cost increases to $800,000–$1 million resulting from trimming of total ship numbers of the class. The IPS is a dual system, with each half consisting of a gas turbine prime mover directly coupled to an electrical generator, which in turn provides power for an electric motor that drives a propeller shaft. Ultimately, the navy determined that Aegis was its preferred combat system option. [89] This proposal was dropped when the PMM motor failed to demonstrate that it was ready to be installed in time. Originally, 32 ships were planned, with $9.6 billion research and development costs spread across the class. [13] Procurement was halted after the first three Zumwalts, and the Navy reverted to building more Arleigh Burke destroyers. [34] Also in April, the Pentagon awarded a fixed-price contract with General Dynamics to build the three destroyers, replacing a cost-plus-fee contract that had been awarded to Northrop Grumman. It is claimed that it is superior to the Burke's sonar in littoral ASW, but less effective in blue water/deep sea areas. 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.[43] 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). 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. From then to 2010, various analysis efforts were conducted to assess potential cost-saving alternatives. [24] In April 2016, the total program cost was $22.5 billion, with an average cost of $7.5 billion per ship.[2]. 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 lead ship is named Zumwalt for Admiral Elmo Zumwalt and carries the hull number DDG-1000. At its current cost of $800,000 per round, the LRLAP delivers the same 24 pounds of high explosive as the aforementioned $700 M795 round. [112] Zumwalt uses MK.57 cells which are larger than the Mk.41 cells found on most American destroyers. The concept was originally for an integrated power system (IPS) based on in-hull permanent magnet synchronous motors (PMMs), with Advanced Induction Motors (AIM) as a possible backup solution. The exact choice of engine systems remains somewhat controversial at this point. The USS Zumwalt's Advanced Gun System was designed to use guided precision munitions, the 155mm Long Range Land-Attack Projectile. The USS Michael Monsoor was commissioned in January 2019, while the future USS Lyndon B. Johnson (DDG 1002), the third and final ship of the Zumwalt class was launched in … The second is more alarming: There are … Kirk took CBS News aboard the USS Zumwalt on its journey from Norfolk, Virginia up the Chesapeake Bay to Baltimore, where on Saturday it will be commissioned as a ship of the line. Since the Aegis system has been the navy's chief combat system for the past 30 years when the navy started a BMD program, the combat system it was tested on was the Aegis combat system. [56] The tumblehome hull and composite deckhouse reduce radar return. [27] The Navy concluded from fifteen classified intelligence reports that the DDG-1000s would be vulnerable to forms of missile attacks. 5122 Together With Additional And Dissenting Views) stated: [14], In January 2005, John Young, Assistant Secretary of the Navy for Research, Development, and Acquisition, was so confident of the DD(X)'s improved air defense over the Burke class that between its new radar and ability to fire SM-1, SM-2, and SM-6, "I don't see as much urgency for [moving to] CG(X)" – a dedicated air defense cruiser.[100]. The inverse bow juts forward to slice through the waves. In 2001, Congress cut the DD-21 program by half as part of the SC21 program; to save it, the acquisition program was renamed as DD(X) and heavily reworked. Clearly it is not a good fit as a frontline warship. A combination of the Zumwalt class's hull form, rudder stop locations and propeller size contribute to its improved seakeeping. That year, to keep the program going, Department of Defense officials dialed back the cost of the first Zumwalt destroyer to $3.3 billion, with subsequent ships costing about $2.5 billion. 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. The guided-missile destroyer USS Zumwalt (DDG 1000) arrives at its new homeport in San Diego on Dec. 8, 2016. The PMM was considered to be another technology leap and was the cause of some concern (along with the radar system) from Congress. [28] Many Congressional subcommittee members questioned that the Navy completed such a sweeping re-evaluation of the world threat picture in just a few weeks, after spending some 13 years and $10 billion on the development of the surface ship program known as DD-21, then DD(X), and finally DDG-1000. [66][78], Two spots are available on a large aviation deck with a hangar capable of housing two full size SH-60 helicopters.
