The Navy has been procuring Virginia (SSN-774) class nuclear-powered attack submarines (SSNs) since FY1998. The two Virginia-class boats requested for procurement in FY2017 are to be the 25th and 26th boats in the class. [35] Admiral Kevin McCoy announced that the problems with the Mold-in-Place Special Hull Treatment for the early subs had been fixed in 2011, then Minnesota was built and found to have the same problem. [12][13][14] Designed by General Dynamics's Electric Boat (EB) and Huntington Ingalls Industries, the Virginia-class submarines are the United States Navy's latest undersea warfare platform which incorporates the latest in stealth, intelligence gathering and weapons systems technology. [66], The Block III submarines have two multipurpose Virginia Payload Tubes (VPT) replacing the dozen single purpose cruise missile launch tubes. [128], On 2 December 2019, the Navy announced an order for nine new Virginia-class submarines – eight Block Vs and one Block IV – for a total contract price of $22 billion with an option for a tenth boat. [124], Block V involves 10 boats and may incorporate the Virginia Payload Module (VPM), which would give guided-missile capability when the SSGNs are retired from service. The Navy ’s proposed FY2009 … Navy plans previously called for procuring two Virginia-class boats in FY2020. In order to get the submarine's price down to $2 billion per submarine in FY-05 dollars, the Navy instituted a cost-reduction program to shave off approximately $400 million of each submarine's price tag. Sie wurde in den 1990er Jahren geplant und wird seit 1999 gebaut. In contrast to a traditional bladed propeller, the Virginia class uses pump-jet propulsors (built by BAE Systems),[58] originally developed for the Royal Navy's Swiftsure-class submarines. [120], The long-lead-time materials contract for SSN-792 was awarded on 17 April 2012, with SSN-793 and SSN-794 following on 28 December 2012. [3][189] The long-range shipbuilding plan is for the new SSN to be authorized in 2034, and become operational by 2044 after the last Block VII Virginia is built. The CBO in its 2012 report states that 33 Virginia-class submarines will be procured in the 2013–2032 timeframe,[3] resulting in 49 submarines in total since 16 were already procured by the end of 2012. ROILO GOLEZ, Philippine National Security Adviser (2001-2004). The one Virginia-class boat that the Navy is requesting for procurement in FY2021 would be the 33rd boat in the class. The Virginia class (or SSN-774 class) is a class of nuclear-powered fast attack submarines in service with the United States Navy.The submarines are designed for a broad spectrum of open-ocean and littoral missions. [30] Two submarine-per-year production resumed on 2 September 2011 with commencement of Washington (SSN-787) construction. With this modification, the overall contract is worth $595 million. [29] This contract was designed to bring the Navy's Virginia-class fleet to 18 submarines. The VPM launch tubes/silos will reportedly be similar in design to the ones planned for the Ohio-class replacement. [34] In September 2010, it was found that urethane tiles, applied to the hull to damp internal sound and absorb rather than reflect sonar pulses, were falling off while the subs were at sea. These segments (dubbed rafts) are then inserted into a hull section (a large segment of the pressure hull). Under pressure from Congress, the Navy opted to start buying two boats per year in FY-11, meaning that officials would not be able to get the $2 billion price tag before the service started buying two submarines per year. Due to programming limitations however, this led to design issues for Electric Boat and maintenance problems for the Navy. [185][186] However, other sources believe that production will end with Block V.[187] In addition, data provided in CBO reports tends to vary considerably compared to earlier editions. [114] Compared to earlier Virginia-class submarines about 40% of the bow has been redesigned. [45] The UMMs are the following. Log in to access this content. The Ohio class of nuclear-powered submarines includes the United States Navy's 14 ballistic missile submarines (SSBNs) and its four cruise missile submarines (SSGNs). The main improvement over the Block III is the reduction of major maintenance periods from four to three, increasing each boat's total lifetime deployments by one. [28], In December 2008, the Navy signed a $14 billion contract with General Dynamics and Northrop Grumman to supply eight submarines. Only limited by food and maintenance requirements. [3], Initially dubbed Future Attack Submarine[188] and Improved Virginia class in Congressional Budget Office (CBO) reports,[3] the SSN(X) or Improved Virginia-class submarines will be an evolved version of the Virginia class. Die Virginia-Klasse ist eine Klasse von nuklear getriebenen Jagd- U-Booten der United States Navy. Von dieser Klasse sind bis zu 30 Einheiten geplant, um damit im 21. [32], The first full-duration six-month deployment was successfully carried out from 15 October 2009 to 13 April 2010. Modular construction techniques incorporated during construction include constructing large segments of equipment outside the hull. Roughly a decade will be spent identifying, designing, and demonstrating new technologies before an analysis of alternatives is issued in 2024. The Virginia class is built through an industrial arrangement designed to maintain both GD Electric Boat and Newport News Shipbuilding, the only two U.S. shipyards capable of building nuclear-powered submarines. [110], Block II involved 6 boats; they were built in four sections rather than ten sections, saving about $300 million per boat. An initial small team has been formed to consult with industry and identify the threat environment and technologies the submarine will need to operate against in the 2050-plus timeframe. [121][122] The U.S. Navy has awarded General Dynamics Electric Boat a $208.6 million contract modification for the second fiscal year (FY) 14 Virginia-class submarine, SSN-793, and two FY 15 submarines, SSN-794 and SSN-795. [11] Virginia-class submarines were the first US Navy warships designed with the help of the computer-aided design (CAD) and visualization technology CATIA. [109] Block I boats were built in 10 modules with each submarine requiring roughly 7 years (84 months) to build. The boat has received $915.7 million in prior-year “regular” advance procurement (AP) funding, and $289.0 million in prior-year Economic Order Quantity (EOQ) AP funding for components of boats being procured under the FY2019-FY2023 MYP contract. These 20 submarines (10 Block V, 5 Block VI, 5 Block VII) would carry VPM bringing the total number of Virginia-class submarines to 48 (including the 28 submarines in Blocks I, II, III and IV). This modification provides lead-yard services for Virginia-class submarines that will maintain, update and support the Virginia-class design and related drawings and data for … [78][79] In July 2016 General Dynamics was awarded $19 million for VPM development. The first UMM was installed on USS Memphis, a Los Angeles-class submarine. Adding the VPM would increase the cost of each submarine by $500 million (2012 prices). The Navy’s FY2020 budget submission had projected that the Navy would request two Virginia-class boats in FY2021. Issues for Congress regarding the Virginia-class program include the potential impact of the COVID-19 (coronavirus) situation on the execution of U.S. military shipbuilding programs, including the Virginia-class program; whether to provide funding for procuring a second Virginia-class boat in FY2021 (which would be the 10th boat under the MYP contract); the potential industrial-base challenges of building both Columbia-class boats and Virginia-class attack submarines (SSNs) at the same time; and technical risk in the design for the latest (i.e., Block V) version of the Virginia-class submarine. However, program manager Dave Johnson said at a conference on 19 March 2008 that the program was only $30 million away from achieving the $2 billion price goal, and would reach that target on schedule. [84], According to open-source budget documents, Virginia-class submarines are planned to be equipped with a high-energy laser weapon likely to be incorporated into the photonics mast and have a power output of 300–500 kilowatts, based on the submarine's 30 megawatts reactor capacity. The world and the Philippines as Roilo Golez sees it. Huntington Ingalls Industries, Newport News, Electric Boat (long-lead materials only) Full build contract: TBA, 16 February 2017 (long-lead material only), 25 × torpedoes & missiles (torpedo room) + 12 x missiles (VLS tubes). [42][43] Shared components have been maximized and some design choices are also shared between different masts. [123] Block IV consists of 10 submarines. Virginia-class submarines are being procured under a The facilities alternate work on the reactor plant as well as the final assembly, test, outfit, and delivery. The same source also states that 10 additional submarines could be built after Block V submarines, with 5 in the so-called Block VI and 5 in Block VII, largely due to the delays experienced with the "Improved Virginia". The Virginia class submarine is a broad-spectrum US Navy attack submarine, designed to engage enemy naval forces directly. Virginia-Class Attack Submarine ..... 4. Technologies that eliminate or substantially simplify existing submarine hull, mechanical, and electrical systems. [73][74][75], The VPM could potentially carry (non-nuclear) medium-range ballistic missiles. [13], The design of earlier optical periscopes required them to penetrate the pressure hull, reducing the structural integrity of the pressure hull as well as increasing the risk of flooding, and also required the submarine's control room to be located directly below the sail/fin.

This would make the Block V the second-largest US submarine, behind only the Ohio-class (at 560 ft). The Virginia-class submarines come in five “blocks,” each with different, incremental improvements and tweaks related to manufacturing ease and upgrades in … [33] Authorization of full-rate production and the declaration of full operational capability was achieved five months later. Die USS Virginia ist im Juli 2004 unterwegs. The one Virginia-class boat that the Navy is requesting for procurement in FY2021 would be the 33rd boat in the class. [116][117][118], Block IV involved 10 boats. The Naval Submarine League believes that up to 10 Block V boats will be built. The Navy’s FY2021 unfunded priorities list (UPL) reportedly lists the 10th boat as the Navy’s top unfunded priority for FY2021 and states that fully funding this additional boat in FY2021 would require an additional $2.76 billion in funding. The Virginia class (or SSN-774 class) is a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy.The submarines are designed for a broad spectrum of open-ocean and littoral missions. [81], The VPM was designed by BWX Technologies[82] (the same company also designs the missile tubes for the Columbia-class submarine),[83] however, manufacture is undertaken by BAE Systems. [7][8], The class was developed under the codename Centurion, later renamed to New SSN (NSSN). Sign up for 30 days free access to exclusive, behind-the-scenes reporting on defense policy and procurement. [46], In the future, a non-rotational Affordable Modular Panoramic Photonics Mast may be fitted, enabling the submarine to obtain a simultaneous 360° view of the sea surface.[56][57]. Some observers are concerned that this projected valley could lead to a period of heightened operational strain for the SSN force, and perhaps a period of weakened conventional deterrence against potential adversaries such as China. Sonar arrays aboard Virginia-class submarines have an "Open System Architecture" (OSA) which enables rapid insertion of new hardware and software as they become available. The Navy’s proposed FY2021 budget requests the remaining $2,334.7 million needed to complete the boat’s estimated procurement cost, as well as $1,473.8 million in “regular” AP funding for Virginia-class boats to be procured in future fiscal years and $427.4 million in EOQ AP funding for components of boats being procured under the FY2019-FY2023 MYP contract, bringing the total amount of procurement and AP funding requested for the program in FY2021 to $4,235.9 million (i.e., about $4.2 billion), excluding outfitting and post-delivery costs. With your financial support, we hope 2021 brings us the opportunity to travel wherever the story takes us -- whether it’s shipyards in the U.S. or aboard a destroyer in the Pacific -- to provide you with critical coverage of the sea services. They are scheduled to replace older Los Angeles-class submarines, many of which have already been decommissioned. [19], The Virginia class was intended in part as a less expensive alternative to the Seawolf-class submarines ($1.8 billion vs $2.8 billion), whose production run was stopped after just three boats had been completed. CRS-1 is forward-deployed with Combined Task Group 68.6 at Camp Lemonnier, Djibouti. The Virginia-class attack submarine (see Figure 1) was designed to be less expensive and better optimized for post-Cold War submarine missions than the Seawolf-class design. For an overview of the strategic and budgetary context in which the Virginia-class program and other Navy shipbuilding programs may be considered, see CRS Report RL32665, Navy Force The FY2019-FY2023 MYP contract for the Virginia-class program includes a total of nine boats (in annual quantities of 2-2-1-2-2), with an option for adding a 10th boat. [20], In hearings before both House of Representatives and Senate committees, the Congressional Research Service (CRS) and expert witnesses testified that the procurement plans of the Virginia class – one per year, accelerating to two per year beginning in 2012 – would result in high unit costs and an insufficient number of attack submarines, according to some of the witnesses and the committee chairman. [8] Construction on the first two boats of this block was expected to begin in 2019 but was pushed back to 2020, with contracts for long lead time material for SSN-802 and SSN-803 being awarded to General Dynamic's Electric Boat. CRS-SUBMARINE – C-ESM & COMINT SYSTEM DETAILS The whole system uses one common human interface for the system management, tasking, mission monitoring, and result analysis. Block II boats are built in four sections, compared to the ten sections of the Block I boats. [38], The Virginia class incorporates several innovations not found in previous US submarine classes. The future submarines will operate through the end of the 21st century, and potentially into the 22nd century. [37], In 2013, just as two-per-year sub construction was supposed to commence, Congress failed to resolve the United States fiscal cliff, forcing the Navy to attempt to "de-obligate" construction funds. [109], SSN-784 through SSN-791 (8 boats) make up the Third Block or "Flight" and began construction in 2009. [21] In a 10 March 2005 statement to the House Armed Services Committee, Ronald O'Rourke of the CRS testified that, assuming that the production rate remains as planned, "production economies of scale for submarines would continue to remain limited or poor. September 25, 2020 The Sept. 24, 2020 Congressional Research Service report discusses the Navy's Virginia-class attack submarine program. Signals from the masts' sensors are transmitted through optical fiber data lines through signal processors to the control center. www.crs.gov RL32418 . [119] The most costly shipbuilding contract in history was awarded on 28 April 2014 as prime contractor General Dynamics Electric Boat took on a $17.6 billion contract for ten Block IV Virginia-class attack submarines. "[22], In 2001, Newport News Shipbuilding and General Dynamics Electric Boat Company built a quarter-scale version of a Virginia-class submarine dubbed Large Scale Vehicle II (LSV II) Cutthroat.

The Virginia class submarines have brought back the lost advantage that was mentioned by report by Center for Strategic and Budgetary Assessments: “The Emerging Era in Undersea Warfare,” which warned that the technological margin of difference separating the U.S from potential rivals is expected to get much smaller. To reduce costs, the Virginia-class submarines use many "commercial off-the-shelf" (COTS) components, especially in their computers and data networks. The Virginia class, also known as the SSN-774 class, is a class of nuclear-powered cruise missile fast-attack submarines, currently in the military service in the United States Navy. [19][112][113] The LAB sonar array is water-backed—as opposed to earlier sonar arrays which were air-backed—and consists of a passive array and a medium-frequency active array. The Navy’s SSGNs are discussed in CRS Report RS21007, Navy Trident Submarine Conversion (SSGN) Program: Background and Issues for Congress, by Ronald O’Rourke. [26][19] As a result of improvements in the construction process, New Hampshire was US$500 million cheaper, required 3.7 million fewer labor hours to build (25% less), thus shortening the construction period by 15 months (20% less) compared to Virginia. [77] More recent reports state that as a cost reduction measure the VPM would carry only Tomahawk SLCM and possibly unmanned undersea vehicles (UUV) with the new price tag now estimated at $360–380 million per boat (in 2010 prices). Virginia-class boats scheduled for procurement in FY2019-FY2023 are being procured under a multiyear procurement (MYP) contract. Test depth: greater than 800 ft (240 m), allegedly around 1,600 feet (490 m). Most Virginia-class boats procured in FY2019 and subsequent years are to be built with the Virginia Payload Module (VPM), an additional, 84-foot-long, mid-body section equipped with four large-diameter, vertical launch tubes for storing and launching additional Tomahawk missiles or other payloads. [39], Virginia class subs are the first class where all masts share common design - the Universal Modular Mast (UMM) - designed by L3 KEO[41] (previously Kollmorgen).

The integrated raft and hull section form a module which, when joined with other modules, forms a Virginia-class submarine. [18] Each submarine is projected to make 14–15 deployments during its 33-year service life. To maintain a force of around 70 submarines, you have to build two per year. An intuitive user interface allows for fast and easy system usage. The Navy has been procuring Virginia (SSN-774) class nuclear-powered attack submarines (SSNs) since FY1998. The addition of the Virginia-class submarine would mean Congress would be approving two of these vessels for the U.S. Navy, in an attempt to build up to … The 10 Virginia-class boats programmed for procurement in FY2014- FY2018 (two per year for five years) are being procured under a multiyear-procurement (MYP) contract. [126][127] HII Newport News Shipbuilding was awarded a long-lead materials contract for two Block V boats in 2017, the first Block Vs for the company. [72], The Block V submarines built from 2019 onward will have an additional Virginia Payload Module (VPM) mid-body section, increasing their overall length. Depending on the tasks, different roles can be assigned and used. [46], The current photonics masts have a visual appearance so different from the ordinary periscopes that when the submarine is detected, it can be distinctly identified as a Virginia-class vessel. The Navy’s SSGNs are discussed in CRS Report RS21007, Navy Trident Submarine Conversion (SSGN) Program: Background and Issues for Congress, by Ronald O'Rourke. Please make a gift today! This boat was delivered eight months ahead of schedule and $54 million under budget. We’ve harnessed technology to speak directly to sailors, marines, and coast guardsmen all over the world and bring you accurate, in-depth reporting. "[26] Among the claims of "offsetting benefits" that O'Rourke attributes to supporters of a two-facility construction arrangement is that it "would permit the United States to continue building submarines at one yard even if the other yard is rendered incapable of building submarines permanently or for a sustained period of time by a catastrophic event of some kind", including an enemy attack. Propulsion concepts not constrained by a centerline shaft. The vehicle was designed as an affordable test platform for new technologies.[23][24]. Virginia-class submarines will be acquired through 2043, and are expected to remain in service until at least 2060, with later submarines expected to remain into the 2070s. Aus Wikipedia, der freien Enzyklopädie. ", "The Virginia Peel: Why are $2 Billion Dollar Subs Losing Their Skin? This new class of submarines were developed to be less expensive and better optimized for post-Cold War submarine operations than the costly Seawolf-class design, while also serving as a replacement for the aging Los Angeles-class. [27], The Virginia-class Program Office received the David Packard Excellence in Acquisition Award in 1996, 1998, 2008, "for excelling in four specific award criteria: reducing life-cycle costs; making the acquisition system more efficient, responsive, and timely; integrating defense with the commercial base and practices; and promoting continuous improvement of the acquisition process". The VPM will add four more VPTs of the same diameter and greater height, located on the centerline, carrying up to seven Tomahawk missiles apiece, that would replace some of the capabilities lost when the SSGN conversion Ohio-class submarines are retired from the fleet. House and Senate negotiators have included a second Virginia-class submarine in the final 2021 defense authorization bill. They were conceived as a less expensive alternative to the Seawolf-class attack submarines, designed during the Cold War era. A torpedo propulsion system concept from the Pennsylvania State University could allow a torpedo to hit a target 200 nmi (230 mi; 370 km) away and be guided by another asset during the terminal phase. The two Virginia-class boats requested for procurement in FY2016 are to be the 23rd and 24th boats in the class. The Navy’s FY2020 budget submission had projected that the Navy would request two Virginia-class boats in FY2021. This is in contrast to nuclear missile submarines whose role would be to launch nuclear missiles in the case of a major war. [36], Professor Ross Babbage of the Australian National University has called on Australia to buy or lease a dozen Virginia-class submarines from the United States, rather than locally build 12 replacements for its Collins-class submarines. The three Virginia-class boats that the Navy has requested for procurement in FY2020 (which are to have the hull numbers SSN-804, SSN-805, and SSN-812) would be the 31st, 32nd, and 33rdboats in the class. The project was dubbed "2 for 4 in 12," referring to the Navy's desire to buy two boats for $4 billion in FY-12. The Virginia class, also known as the SSN-774 class, is a class of nuclear-powered fast attack submarines (hull classification symbol SSN) in service with the United States Navy.The submarines are designed for a broad spectrum of open-ocean and littoral missions. O'Rourke wrote in 2004 that, "Compared to a one-yard strategy, approaches involving two yards may be more expensive but offer potential offsetting benefits. This enables a cost saving of about $300 million per boat, reducing the overall cost to $2 billion per boat and the construction of two new boats per year.
