Zumwalt is the lead ship of a class of next-generation multi-mission destroyers designed to strengthen naval power from the sea. The second ship, Michael Monsoor, was commissioned in 2019, and the third ship, Lyndon B. Johnson (DDG-1002), is to reach IOC in 2021.[49]. [24] In April 2016, the total program cost was $22.5 billion, with an average cost of $7.5 billion per ship.[2]. Lawmakers and others questioned whether the Zumwalt-class costs too much and whether it provides the capabilities that the military needs. [82][83], In that the Zumwalt class has no AN/SPG-62 fire-control radars that are used for terminal guidance for Standard and Evolved Sea-Sparrow Missiles (ESSMs) anti-aircraft engagements, the SPY-3 will generate Interrupted Continuous Wave Illumination (ICWI) rather than the Continuous Wave Illumination of the AN/SPG-62 fire-control radars. Originally, 32 ships were planned, with $9.6 billion research and development costs spread across the class. The U.S. Navy's Stealth USS Zumwalt Destroyer Finally Fires Its Guns The $4 billion ship was commissioned in 2016, but broke down while passing through the Panama Canal just a month later. [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. 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. The ESSM is considered a point defense weapon not generally used for fleet area defense. [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 second is more alarming: There are … He concludes: The Zumwalt is an unmitigated disaster. [37] The Aegis system, on the other hand was used in the Aegis Ballistic Missile Defense System. 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. Clearly it is not a good fit as a frontline warship. Zumwalt has Converteam's Advanced Induction Motors (AIM), rather than DRS Technologies' Permanent Magnet-Synchronous Motors (PMM). According to Captain Carlson, during the storm, he summoned his executive officer from his cabin to inform him of the sea state six conditions. canals). [66][69] The barrel is water-cooled to prevent overheating and allows a rate of fire of 10 rounds per minute per gun. [32], 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. [117], In 2005, a Critical Design Review (CDR) of the DDG-1000 led to the selection of the Mk 110 57 mm (2.2 in) cannon to defend the destroyer against swarming attacks by small fast boats; the Mk 110 has a rate of fire of 220 rpm and a range of 9 nmi (17 km; 10 mi). [33], On 6 April 2009, Defense Secretary Robert Gates announced that DoD's proposed 2010 budget will end the DDG-1000 program at a maximum of three ships. All of its sharp angles are meant to deflect radar beams sent out by anyone trying to find it. [57] In 2008, Defense News reported there had been problems sealing the composite construction panels of this area; Northrop Grumman denied this. The Zumwalt cost more than $4.4bn and was commissioned in October in Maryland. [25], Northrop Grumman was awarded a $90M contract modification for materials and production planning on 13 November 2007. 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 … Water sleeting along the sides, along with passive cool air induction in the mack, reduces infrared signature. 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 (excluding R&D costs)[1][20][21][2] and well exceeding the per-unit cost of a nuclear-powered Virginia-class submarine ($2.688 billion). It cost $11.1 billion to develop the Zumwalt class, almost as much as the $12.6 billion it cost to actually buy them, the Government Accountability Office reported in April. Among the new technologies are automated gun mounts. The original concept for the land-attack destroyer was floated more than 15 years ago then underwent several permutations. The USS Zumwalt, a stealth ship commissioned in October and costing upward of $4.4 billion, has already had engineering and propulsion problems and experienced a … The system consists of pods of VLS cells distributed around the outer shell of the ship, with a thin steel outer shell and a thick inner shell. [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. 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. Mike Fredenburg analyzed the program for National Review after Zumwalt broke down in the Panama Canal in November 2016, and he concluded that the ship's problems "are emblematic of a defense procurement system that is rapidly losing its ability to meet our national security needs. 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. WASHINGTON — The U.S. Navy’s first stealth destroyer, Zumwalt, test-fired an SM-2 missile out of its MK 57 Vertical Launching System on Oct. 13, … 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. [30] The lack of anti-ballistic missile capability may represent a lack of compatibility with SM-2/SM-3. [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. [27] 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. The Enterprise Air Surveillance Radar (EASR) is a new design surveillance radar that is to be installed in the second Gerald R. Ford-class aircraft carrier, John F. Kennedy, in lieu of the Dual Band radar. [63], The usefulness of the stealth features has been questioned. The Zumwalt-class destroyer is not an Aegis system. The U.S. House of Representatives allotted the Navy only enough money to begin construction on one destroyer, as a "technology demonstrator". [37] Since then, the 22-foot (6.7 m) radar system has been canceled with the CG(X) and it has been determined that a 14-foot (4.3 m) radar could be used either on DDG-51 or on DDG-1000, though it would not have the performance the navy predicts would be needed "to address the most challenging threats". [14] The class design emerged from the DD-21 "land attack destroyer" program as "DD(X)". [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. [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. [verification needed][108], With the awarding of the development contract to the next generation Air and Missile Defense S-Band Radar to Raytheon, deliberation to put in place this radar on the Zumwalt-class destroyer is no longer being actively discussed. French naval architects believed that tumblehome, in which the beam of the vessel narrowed from the waterline to the upper deck, would create better freeboard, greater seaworthiness, and, as Russian battleships were to find, would be ideal for navigating through narrow constraints (e.g. This system consists of an advanced 155 mm gun and its Long Range Land Attack Projectile (LRLAP). In late December 2005, the House and Senate agreed to continue funding the program. 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. [66][78], Two spots are available on a large aviation deck with a hangar capable of housing two full size SH-60 helicopters. 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. [citation needed]. 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. [56], A dual-band sonar controlled by a highly automated computer system will be used to detect mines and submarines. Among the first technologies tested was an underwater discharge waterjet from Rolls-Royce Naval Marine, Inc. called AWJ-21. Stream CBSN live or on demand for FREE on your TV, computer, tablet, or smartphone. The US Navy is eyeing a … The exact choice of engine systems remains somewhat controversial at this point. "[56], The acoustic signature is comparable to that of the Los Angeles-class submarines. While optimized for volume search, the horizon search capability is limited. [118][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. Significant software modifications are required to support the ICWI, transmit and receive link messages to the missiles. [14], The Zumwalt-class destroyer reintroduces the tumblehome hull form, a hull form not seen to this extent since the Russo-Japanese War in 1905. 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. [65] The tumblehome has been reintroduced in the 21st century to reduce the radar return of the hull. The Navy said the world threat picture had changed in such a way that it made more sense to build at least eight more Burkes, rather than DDG-1000s. The stability of the DDG-1000 hull design in heavy seas has been a matter of controversy. [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.
