On 14 March 2023, the trilateral Australian-British-American security pact known as [[AUKUS]] announced that the [[Royal Australian Navy]] would purchase three ''Virginia''-class submarines as a stopgap measure between the retirement of their conventionally powered {{sclass|Collins|submarine}}s and the acquisition of the future [[SSN-AUKUS]] class submarines. If the SSN-AUKUS fell behind schedule, Australia would have the option of purchasing two additional ''Virginia''-class submarines.<ref name="AUKUSMar23">{{cite press release |author1=Prime Minister of Australia Anthony Albanese |author2=Prime Minister of the United Kingdom Rishi Sunak |author3=President of the United States of America Joseph R.

The ''Virginia'' class was intended in part as a less expensive alternative to the {{sclass|Seawolf|submarine|1}} ($1.8&nbsp;billion vs $2.8&nbsp;billion), whose production run was canceled after just three boats had been completed. To reduce costs, the ''Virginia''-class submarines use many "[[commercial off-the-shelf]]" (COTS) components, especially in their computers and data networks. Improvements in shipbuilding technology have trimmed production costs below the $1.8&nbsp;billion projected fiscal year 2009 dollars.<ref name="baker1005" />

In hearings before both [[U.S. House of Representatives|House of Representatives]] and [[U.S. Senate|Senate]] committees, the [[Congressional Research Service]] (CRS) and expert witnesses testified that the annual procurement rate of only one ''Virginia''-class boat—rising to two in 2012—would result in excessive unit production costs, yet an insufficient complement of attack submarines.<ref name="fas1">{{cite web |date=27 June 2000 |title=Statement of The Honorable Duncan Hunter, Chairman, Subcommittee on Military Procurement, Submarine Force Structure and Modernization |url=https://fas.org/man/congress/2000/00-06-27hunter.htm |url-status=dead |archive-url=https://web.archive.org/web/20150612192741/http://fas.org/man/congress/2000/00-06-27hunter.htm |archive-date=12 June 2015 |access-date=26 April 2015 |publisher=[[Federation of American Scientists]] Military Analysis Network}}</ref> 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."<ref name="orourke1">{{cite web |url=http://www.house.gov/hasc/testimony/109thcongress/Projection%20Forces/3-10-05O'RourkeCRS.pdf |title=Statement of Ronald O'Rourke Specialist in National Defense Congressional Research Service before the House Armed Services Committee Subcommittee on Projection Forces Hearing on Navy Force Architecture and Ship Construction |date=10 March 2005 |access-date=1 March 2008 |archive-url=http://webarchive.loc.gov/all/20060604000350/http%3A//www%2Ehouse%2Egov/hasc/testimony/109thcongress/Projection%2520Forces/3%2D10%2D05O%27RourkeCRS%2Epdf |archive-date= 4 June 2006}}</ref>

In 2001, [[Newport News Shipbuilding]] and the [[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 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.<ref name="fas3">{{cite web|url=https://fas.org/programs/ssp/man/uswpns/navy/submarines/ssn774_virginia.html |title=SSN-774 Virginia-class NSSN New Attack Submarine |publisher=[[Federation of American Scientists]] |date=19 January 2009 |access-date=6 August 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110707133458/http://www.fas.org/programs/ssp/man/uswpns/navy/submarines/ssn774_virginia.html |archive-date=7 July 2011}}</ref> Under the present arrangement, the Newport News facility builds the stern, habitability, machinery spaces, torpedo room, sail, and bow, while Electric Boat builds the engine room and control room. The facilities alternate work on the reactor plant as well as the final assembly, test, outfit, and delivery.

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."<ref name=RL32418>{{cite report |last=O'Rourke |first=Ronald |title=Navy Virginia (SSN-774) Class Attack Submarine Procurement: Background and Issues for Congress |url=https://fas.org/sgp/crs/weapons/RL32418.pdf |date=26 March 2015 |publisher=Congressional Research Service |page=6 |access-date=4 June 2015 |archive-url=https://web.archive.org/web/20150628192435/http://www.fas.org/sgp/crs/weapons/RL32418.pdf |archive-date=28 June 2015 |url-status=live}}</ref> 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.

In order to get the submarine's price down to $2&nbsp;billion per submarine in FY-05 dollars, the Navy instituted a cost-reduction program to shave off approximately $400&nbsp;million of each submarine's price tag. The project was dubbed "2 for 4 in 12," referring to the Navy's desire to buy two boats for $4&nbsp;billion in FY-12. 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&nbsp;billion price tag before the service started buying two submarines per year. However, program manager Dave Johnson said at a conference on 19 March 2008 that the program was only $30&nbsp;million away from achieving the $2&nbsp;billion price goal, and would reach that target on schedule.<ref>{{cite web|url=http://insidedefense.com/secure/defense_docnum.asp?f=defense_2002.ask&docnum=NAVY-21-12-4|title=Cost reduction|access-date=25 March 2008}}{{dead link|date=May 2016|bot=medic}}{{cbignore|bot=medic}}</ref>

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".<ref>{{cite press release |url=http://www.navy.mil/submit/display.asp?story_id=40781 |title=Navy's Virginia Class Program Recognized for Acquisition Excellence |location=Washington, DC |publisher=Team Submarines Public Affairs |date=8 November 2008 |access-date=26 April 2015 |archive-url=https://web.archive.org/web/20150605232956/http://www.navy.mil/submit/display.asp?story_id=40781 |archive-date=5 June 2015 |url-status=dead}}</ref>

In December 2008, the Navy signed a $14&nbsp;billion contract with General Dynamics and Northrop Grumman to supply eight submarines. The contract required the delivery of one submarine in each of fiscal 2009 and 2010, and two submarines on each of fiscal 2011, 2012, and 2013.<ref>{{cite news|url=https://www.nytimes.com/reuters/2008/12/22/business/business-us-navy-submarines.html|title=General Dynamics And Northrop Awarded Submarine Deal|work=[[The New York Times]]|date=22 December 2008}}{{dead link|date=September 2010}}</ref> This contract was designed to bring the Navy's ''Virginia''-class fleet to 18 submarines.

On 21 June 2008, the Navy christened {{USS|New Hampshire|SSN-778|6}}, the first Block II submarine. This boat was delivered eight months ahead of schedule and $54&nbsp;million under budget. Block&nbsp;II boats are built in four sections, compared to the ten sections of the Block I boats. This enables a cost saving of about $300&nbsp;million per boat, reducing the overall cost to $2&nbsp;billion per boat and the construction of two new boats per year. Beginning in 2010, new submarines of this class were to have included a software system that can monitor and reduce their [[Electromagnetism|electromagnetic]] signatures when needed.<ref>{{cite web |first=John |last=Pike |url=http://www.globalsecurity.org/military/systems/ship/ssn-774-spiral-1.htm |title=SSN-774 Virginia-class NSSN New Attack Submarine |website=Global Security |access-date=26 April 2015 |archive-url=https://web.archive.org/web/20150605021257/http://www.globalsecurity.org/military/systems/ship/ssn-774-spiral-1.htm |archive-date=5 June 2015 |url-status=live}}</ref>

===Photonics masts===
[[File:Manette de Xbox360, USS Colorado.jpg|thumb|A sailor using an [[Xbox 360 controller]] to control the photonic masts of the [[USS Colorado (SSN-788)]] in 2018. It is the first submarine to use this Xbox controller.]]

The ''Virginia'' class is the first to utilize photonic sensors instead of a traditional [[periscope]]. The class is equipped with high-[[image resolution|resolution]] cameras, along with light-intensification and [[thermographic camera|infrared sensors]], an infrared [[laser rangefinder]], and an integrated [[Electronic Support Measures]] (ESM) array. Two redundant sets of these sensors are mounted on two [[AN/BVS-1]] [[photonics mast]]s<ref name= "baker1005" /> located outside the [[pressure hull]]. Signals from the masts' sensors are transmitted through [[optical fiber]] data lines through [[signal processor]]s to the control center.<ref>{{cite web |first=Claudio |last=Paschoa |url = http://www.marinetechnologynews.com/blogs/umm-photonics-mast-for-virginia-class-attack-submarines-700510 |title=UMM Photonics Mast for ''Virginia''-class Attack | work =Marine technology news |date= 11 September 2014 |access-date=26 April 2015 |archive-url= https://web.archive.org/web/20150402162107/http://www.marinetechnologynews.com/blogs/umm-photonics-mast-for-virginia-class-attack-submarines-700510 |archive-date=2 April 2015 |url-status=live}}</ref> Visual feeds from the masts are displayed on [[liquid-crystal display]] interfaces in the command center.<ref name= "USW W99">{{cite web |last1=Graves |first1=Barbara |last2= Whitman |first2=Edward |date=Winter 1999 |title=''Virginia''-class: America's Next Submarine |url= http://www.public.navy.mil/subfor/underseawarfaremagazine/Issues/Archives/issue_02/virginia_class.htm |url-status=dead |archive-url= https://web.archive.org/web/20150831001014/http://www.public.navy.mil/subfor/underseawarfaremagazine/Issues/Archives/issue_02/virginia_class.htm |archive-date=31 August 2015 |access-date= 26 April 2015 |publisher=US Navy |volume=1 |number=2}}</ref>

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.<ref>{{cite web |last=Holian |first=Thomas |date=Fall 2004 |title=Eyes from the Deep: A History of U.S. Navy Submarine Periscopes |url= http://www.public.navy.mil/subfor/underseawarfaremagazine/Issues/Archives/issue_24/eyes.htm |publisher=US Navy |access-date=26 April 2015 |archive-url= https://web.archive.org/web/20150904031441/http://www.public.navy.mil/subfor/underseawarfaremagazine/Issues/Archives/issue_24/eyes.htm |archive-date=4 September 2015 |url-status=dead}}</ref> Implementation of photonics masts (which do not penetrate the pressure hull) enabled the submarine control room to be relocated to a position inside the pressure hull which is not necessarily directly below the sail.<ref name=":0" />

The current photonics masts have a visual appearance so different from ordinary periscopes that when the submarine is detected, it can be distinctly identified as a ''Virginia''-class vessel. As a result, current photonic masts will be replaced with Low-Profile Photonics Masts (LPPM) which resemble traditional submarine periscopes more closely.<ref name=":0" />

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.<ref>{{cite web |date= October 2012 |title=Affordable Modular Panoramic Photonics Mast |url= http://www.onr.navy.mil/~/media/Files/Fact-Sheets/31/Affordable-Modular-Panoramic-Photonics.ashx |url-status=dead |archive-url = https://web.archive.org/web/20150402125034/http://www.onr.navy.mil/~/media/Files/Fact-Sheets/31/Affordable-Modular-Panoramic-Photonics.ashx |archive-date=2 April 2015 |access-date=26 April 2015 |publisher=Office of Naval Research}}</ref><ref>{{cite web |title= Affordable Modular Panoramic Photonics |url= http://www.onr.navy.mil/en/Media-Center/Fact-Sheets/Affordable-Modular-Panoramic-Photonics-Mast.aspx |url-status=dead |archive-url= https://web.archive.org/web/20150402144708/http://www.onr.navy.mil/en/Media-Center/Fact-Sheets/Affordable-Modular-Panoramic-Photonics-Mast.aspx |archive-date=2 April 2015 |access-date=26 April 2015 |publisher=Office of Naval Research}}</ref>

=== Improved sonar systems ===
[[Sonar]] arrays aboard ''Virginia''-class submarines have an "[[Open system (computing)|Open System Architecture]]" (OSA) which enables rapid insertion of new hardware and software as they become available. [[Hardware upgrade]]s (dubbed Technology Insertions) are usually carried out every four years, while [[software update]]s (dubbed Advanced Processor Builds) are carried out every two years. ''Virginia''-class submarines feature several types of sonar arrays.<ref name="npg13">{{cite web |date=2013 |title=US Navy Program Guide 2013 |url= http://www.navy.mil/navydata/policy/seapower/npg13/top-npg13.pdf |url-status=dead |archive-url= https://web.archive.org/web/20160821160828/http://www.navy.mil/navydata/policy/seapower/npg13/top-npg13.pdf |archive-date=21 August 2016 |access-date=26 April 2015 |publisher=US Navy}}</ref>

This required extensive construction activities within the narrow confines of the pressure hull which was time-consuming and dangerous. Modular construction was implemented in an effort to overcome these problems and make the construction process more efficient. Modular construction techniques incorporated during construction include constructing large segments of equipment outside the hull. These segments (dubbed rafts) are then inserted into a hull section (a large segment of the pressure hull). The integrated raft and hull section form a module which, when joined with other modules, forms a ''Virginia''-class submarine.<ref name=Holmander>{{cite news |first1=John D. |last1=Holmander |first2=Thomas |last2=Plante |title=The Four-Module Build Plan: The Second Decade of Virginia-class Construction Gets Better |journal=Undersea Warfare |url=http://www.public.navy.mil/subfor/underseawarfaremagazine/Issues/Archives/issue_43/build_plan.html |publisher=US Navy |date=Winter 2011 |issue=43 |access-date=4 June 2015 |archive-url=https://web.archive.org/web/20150924120328/http://www.public.navy.mil/subfor/underseawarfaremagazine/Issues/Archives/issue_43/build_plan.html |archive-date=24 September 2015 |url-status=dead}}</ref> Block I boats were built in 10 modules with each submarine requiring roughly 7 years (84 months) to build.<ref>{{cite conference |last1=Johnson |first1=David C. |first2=George M. |last2=Drakeley |first3=George M. |last3=Smith |title=Engineering the Solution: Virginia-Class Submarine Cost Reduction |conference=Engineering the Total Ship (ETS) 2008 |url=https://www.navalengineers.org/SiteCollectionDocuments/2008%20Proceedings%20Documents/ETS%202008/VA%20Class%20ASNE%20Paper%20FINAL.pdf |location=Falls Church, Virginia |publisher=American Society of Naval Engineers |date=23 September 2008 |access-date=21 April 2013 |url-status=dead |archive-url=https://web.archive.org/web/20140203084604/https://www.navalengineers.org/SiteCollectionDocuments/2008%20Proceedings%20Documents/ETS%202008/VA%20Class%20ASNE%20Paper%20FINAL.pdf |archive-date=3 February 2014}}</ref>

Block II comprised 6 boats; they were built in four sections rather than ten, saving about $300&nbsp;million per boat. Block II boats (except the ''New Hampshire'') were also built under a multi-year procurement agreement as opposed to a block-buy contract in Block I, enabling savings in the range of $400&nbsp;million ($80&nbsp;million per boat).<ref name=RL32418 /><ref name=Butler /> As a result of improvements in the construction process, ''New Hampshire'' (SSN-778) was US$500&nbsp;million cheaper, required 3.7&nbsp;million fewer labor hours to build (25% less), thus shortening the construction period by 15 months (20% less) compared to ''Virginia''.<ref name=Holmander />

==SSN(X)/Improved ''Virginia''==
{{Main|SSN(X)-class submarine}}
Initially dubbed Future Attack Submarine<ref>{{cite web|url=https://fas.org/man/dod-101/sys/ship/fas.htm|title=Future Attack Submarine|publisher=Federation of American Scientists|access-date=25 November 2015|archive-url=https://web.archive.org/web/20151126100134/https://fas.org/man/dod-101/sys/ship/fas.htm|archive-date=26 November 2015|url-status=live}}</ref> and Improved ''Virginia'' class in early Congressional Budget Office (CBO) reports,<ref name="cbo" /> the SSN(X) will instead be a largely new design that initially supplements and eventually replaces the ''Virginia'' class submarines.

In late 2014, the US Navy began early preparation work on the SSN(X). It was planned that the first submarine would be procured in 2025. However, their introduction (i.e., procurement of the first submarine) has been pushed back to 2033/2034.<ref name="cbo" /><ref>{{cite report |title=An Analysis of the Navy's Fiscal Year 2011 Shipbuilding Plan |url=http://www.cbo.gov/sites/default/files/05-25-navyshipbuilding.pdf |publisher=Congressional Budget Office |number=Pub. No. 4116 |date=May 2010 |access-date=4 June 2015 |archive-url=https://web.archive.org/web/20141208153155/http://www.cbo.gov/sites/default/files/05-25-navyshipbuilding.pdf |archive-date=8 December 2014 |url-status=live}}</ref> 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. Roughly a decade would be spent identifying, designing, and demonstrating new technologies before an analysis of alternatives is issued in 2024. 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.

In 2019, the Congressional Budget Office estimated that the SSN(X) boats could cost up to $5.5&nbsp;billion per hull. The current ''Virginia''-class boats cost about $2.8&nbsp;billion per hull, while the Block V boats with the 80-foot Virginia Payload Module will cost about $3.2&nbsp;billion. "The Navy indicates that the next-generation attack submarine should be faster, stealthier, and able to carry more torpedoes than the ''Virginia'' class, similar to the ''Seawolf''-class submarine. CBO therefore assumed that the SSN(X) would be a ''Seawolf''-sized SSN, which displaces about 9,100 tons when submerged, and would have an all-new design in keeping with the Navy's description of it as a fast, lethal next-generation attack submarine", the CBO wrote.<ref>{{cite news |first=Sam |last=LaGore |title=Next Generation SSN(X) Attack Sub 'Is Going to Carry a Lot of Torpedoes,' Says Admiral |url=https://news.usni.org/2021/11/22/next-generation-ssnx-attack-sub-is-going-to-carry-a-lot-of-torpedoes-says-admiral |work=USNI News |publisher=U.S. Naval Institute |date=22 November 2021 |access-date=24 November 2021 }}</ref>
