The '''''Ohio'' class''' of [[nuclear submarine|nuclear-powered submarines]] includes the [[United States Navy]]'s 14 [[ballistic missile submarine]]s (SSBNs) and its 4 [[cruise missile submarine]]s (SSGNs). Each [[Displacement (ship)|displacing]] 18,750 tons submerged, the ''Ohio''-class boats are the largest submarines ever built for the U.S. Navy and are capable of carrying 24 [[UGM-133 Trident II|Trident II]] missiles apiece.

All the ''Ohio''-class submarines, except for {{USS|Henry M. Jackson|SSBN-730|6}}, are named for [[U.S. state]]s, which U.S. Navy tradition had previously reserved for [[battleship]]s and later [[cruiser]]s. The ''Ohio'' class is to be gradually replaced by the {{sclass|Columbia|submarine|4}} beginning in 2031.

== Description ==
The ''Ohio''-class submarine was designed for extended strategic deterrent patrols. Each submarine is assigned two complete crews, called the Blue crew and the Gold crew, each typically serving 70-to-90-day deterrent patrols. To decrease the time in port for crew turnover and replenishment, three large logistics hatches have been installed to provide large-diameter resupply and repair access. These hatches allow rapid transfer of supply pallets, equipment replacement modules, and machinery components, speeding up replenishment and maintenance of the submarines. Moreover, the "stealth" ability of the submarines was significantly improved over all previous ballistic-missile subs.'' Ohio'' was virtually undetectable in her sea trials in 1982, giving the U.S. Navy extremely advanced flexibility.<ref>D. Douglas Dalgleish and Larry Schweikart, Trident. Carbondale, Illinois: Southern Illinois University Press. 1984.</ref>

The class's design allows the boat to operate for about 15 years between major overhauls. These submarines are reported to be as quiet at their cruising speed of {{convert|20|kn|lk=in}} or more as the previous {{sclass|Lafayette|submarine|1}}s at {{convert|6|kn}}, although exact information remains classified.<ref>{{Cite book|last=Lee|first=T.

The ''Ohio''-class submarines were constructed from sections of hull, with each four-deck section being {{convert|42|ft|abbr=on}} in diameter.<ref name="Adcock_p40" /><ref name="Adcock_p41" /> The sections were produced at the [[General Dynamics Electric Boat]] facility, [[Quonset Point]], [[Rhode Island]], and then assembled at its shipyard at [[Groton, Connecticut]].<ref name="Adcock_p40" />

The US Navy has a total of 18 ''Ohio''-class submarines which consist of 14 ballistic missile submarines (SSBNs), and four [[cruise missile submarine]]s (SSGNs). The SSBN submarines provide the sea-based leg of the U.S. [[nuclear triad]]. Each SSBN submarine is armed with up to 20 [[UGM-133 Trident II|Trident II]] [[submarine-launched ballistic missile]]s (SLBM). Each SSGN is capable of carrying 154 [[Tomahawk (missile family)|Tomahawk]] [[cruise missile]]s, plus a complement of [[Harpoon missile]]s to be fired through their [[torpedo tube]]s.

== History ==
{{See also|STRAT-X}}

The ''Ohio'' class was designed in the 1970s to carry the concurrently designed [[Trident (missile)|Trident]] [[submarine-launched ballistic missile]]. The first eight ''Ohio''-class submarines were armed at first with 24 Trident I C4 SLBMs.<ref name="Adcock_p40" /> Beginning with the ninth Trident submarine, {{USS|Tennessee|SSBN-734|2}}, the remaining boats were equipped with the larger, three-stage [[Trident missile|Trident II D5 missile]].<ref name="Adcock_p41" /> The Trident I missile carries eight [[multiple independently targetable reentry vehicle]]s, while the Trident II missile carries 12, in total delivering more destructive power than the Trident I missile and with greater accuracy. Starting with {{USS|Alaska|SSBN-732|2}} in 2000, the Navy began converting its remaining ballistic missile submarines armed with C4 missiles to carry D5 missiles. This task was completed in mid-2008. The first eight submarines had their home ports at [[Naval Base Kitsap|Bangor, Washington]], to replace the submarines carrying [[Polaris missile|Polaris A3 missile]]s that were then being decommissioned. The remaining 10 submarines originally had their home ports at [[Naval Submarine Base Kings Bay|Kings Bay, Georgia]], replacing the [[Poseidon missile|Poseidon]] and Trident Backfit submarines of the Atlantic Fleet.

=== SSBN/SSGN conversions ===

In 1994, the [[Nuclear Posture Review]] study determined that, of the 18 ''Ohio'' SSBNs the U.S. Navy would be operating in total, 14 would be sufficient for the strategic needs of the U.S. The decision was made to convert four ''Ohio''-class boats into SSGNs capable of conducting conventional [[Military strike|land attack]] and [[Special forces|special operations]]. As a result, the four oldest boats of the class—''Ohio'', ''Michigan'', ''Florida'', and ''Georgia''—progressively entered the conversion process in late 2002 and were returned to active service by 2008.<ref name=USNF>{{Cite web|title=Guided Missile Submarines&nbsp;– SSGN|url=http://www.navy.mil/navydata/fact_display.asp?cid=4100&tid=300&ct=4|publisher=Navy.mil|work=U.S. Navy|date=10 November 2011|access-date=27 January 2012|archive-url=https://web.archive.org/web/20120108080936/http://www.navy.mil/navydata/fact_display.asp?cid=4100&tid=300&ct=4|archive-date=8 January 2012|url-status=dead}}</ref> The boats could thereafter carry 154 [[Tomahawk (missile family)|Tomahawk cruise missile]]s and 66 special operations personnel, among other capabilities and upgrades.<ref name=USNF/> The cost to refit the four boats was around US$1&nbsp;billion (2008 dollars) per vessel.<ref name=Nuclear_lives>{{cite web |url=https://fas.org/sgp/crs/weapons/RS21007.pdf |title=Navy Trident Submarine Conversion (SSGN) Program: Background and Issues for Congress |last=O'Rourke |first=Ronald |date=22 May 2008 |work=[[Congressional Research Service]] |via=Fas.org|access-date=7 February 2012 |archive-url=https://web.archive.org/web/20111106064952/http://www.fas.org/sgp/crs/weapons/RS21007.pdf |archive-date=6 November 2011 |url-status=live}}</ref> During the conversion of these four submarines to SSGNs (see below), five of the remaining submarines, {{USS|Pennsylvania|SSBN-735|2}}, {{USS|Kentucky|SSBN-737|2}}, {{USS|Nebraska|SSBN-739|2}}, {{USS|Maine|SSBN-741|2}}, and {{USS|Louisiana|SSBN-743|2}}, were transferred from Kings Bay to Bangor.{{cn|date=April 2023}}

The conversion modified 22 of the 24 {{convert|88|in|m|adj=on}} diameter Trident missile tubes to contain large [[vertical launching system|vertical launch systems]], one configuration of which may be a cluster of seven [[Tomahawk (missile family)|Tomahawk cruise missiles]]. In this configuration, the number of cruise missiles carried could be a maximum of 154, the equivalent of what is typically deployed in a surface battle group. Other payload possibilities include new generations of [[supersonic]] and [[hypersonic]] cruise missiles, and Submarine Launched Intermediate Range Ballistic Missiles,{{cn|date=July 2024}} [[unmanned aerial vehicle]]s, the [[ADM-160 MALD]], sensors for antisubmarine warfare or intelligence, surveillance, and reconnaissance missions, counter mine warfare payloads such as the [[Long-Term Mine Reconnaissance System|AN/BLQ-11 Long Term Mine Reconnaissance System]], and the [[broaching universal buoyant launcher]] and [[stealthy affordable capsule system]] specialized payload canisters.{{cn|date=April 2023}}

The missile tubes also have room for stowage canisters that can extend the forward deployment time for special forces. The other two Trident tubes are converted to swimmer lockout chambers. For special operations, the [[Dry Combat Submersible]] (which replaced the [[Advanced SEAL Delivery System]]), as well as the [[dry deck shelter]], can be mounted on the lockout chamber and the boat will be able to host up to 66 special-operations sailors or Marines, such as [[Navy SEAL]]s, or [[United States Marine Corps|USMC]] [[MARSOC]] teams. Improved communications equipment installed during the upgrade allows the SSGNs to serve as a forward-deployed, clandestine Small Combatant Joint Command Center.<ref>{{cite news |url=http://www.gdeb.com/news/ebnews/ebnews0206.pdf|type=Newsletter |title=USS Ohio Returns To Service As Navy's First SSGN |work=Electric Boat News |publisher=[[General Dynamics Electric Boat]] |date=February 2006 |archive-url=https://web.archive.org/web/20090731060602/http://www.gdeb.com/news/ebnews/ebnews0206.pdf |archive-date=2009-07-31}}</ref>

On 26 September 2002, the Navy awarded [[General Dynamics Electric Boat]] a US$442.9 million contract to begin the first phase of the SSGN submarine conversion program. Those funds covered only the initial phase of conversion for the first two boats on the schedule. Advance procurement was funded at $355 million in [[fiscal year]] 2002, $825 million in the FY 2003 budget and, through the five-year defense budget plan, at $936 million in FY 2004, $505 million in FY 2005, and $170 million in FY 2006. Thus, the total cost to refit the four boats is just under $700 million per vessel.{{cn|date=April 2023}}

In November 2002, ''Ohio'' entered a [[drydock|dry-dock]], beginning her 36-month [[Refueling and Overhaul|refueling and missile-conversion overhaul]]. Electric Boat announced on 9 January 2006 that the conversion had been completed. The converted ''Ohio'' rejoined the fleet in February 2006, followed by ''Florida'' in April 2006. The converted ''Michigan'' was delivered in November 2006. The converted ''Ohio'' went to sea for the first time in October 2007.

==Replacement==
{{main|Columbia-class submarine}}

The [[United States Department of Defense|U.S. Department of Defense]] anticipated a continued need for a [[Nuclear triad|sea-based strategic nuclear force]].{{cn|date=July 2024}} The first of the current ''Ohio''-class SSBNs was expected to be retired by 2029,{{cn|date=July 2024}} so the replacement submarine would need to be seaworthy by that time. A replacement was expected to cost over $4 billion per unit compared to ''Ohio''{{'}}s $2 billion.<ref name="Frost" /> The U.S. Navy explored two options. The first option was a variant of the {{sclass|Virginia|submarine|0}} nuclear-powered attack submarines. The second option was a dedicated SSBN, either with a new hull or based on an overhaul of the current ''Ohio'' class.{{cn|date=July 2024}}

With the cooperation of both Electric Boat and Newport News Shipbuilding, in 2007, the U.S. Navy began a cost-control study.{{cn|date=July 2024}} Then in December 2008, the U.S. Navy awarded Electric Boat a contract for the missile compartment design of the ''Ohio''-class replacement, worth up to $592 million. Newport News is expected to receive close to 4% of that project. In April 2009, [[United States Secretary of Defense|U.S. Defense Secretary]] [[Robert M. Gates]] stated that the U.S. Navy was expected to begin such a program in 2010.<ref name="Frost" /> The new vessel was scheduled to enter the design phase by 2014. If a new hull design was to be used, the program needed to be initiated by 2016 to meet the 2029 deadline.{{cn|date=July 2024}}{{update after|2014|1|1}}

The ''Columbia'' class was officially designated on 14 December 2016, by Secretary of the Navy [[Ray Mabus]], and the lead submarine will be {{USS|District of Columbia|SSBN-826}}.<ref>{{cite web|url=https://news.usni.org/2016/12/13/secnav-mabus-to-officially-designate-first-orp-boat-uss-district-of-columbia-ssbn-826|title=SECNAV Mabus to Officially Designate First ORP Boat USS ''Columbia'' (SSBN-826)|website=USNI News|date=13 December 2016|access-date=8 November 2022}}</ref> The Navy wants to procure the first ''Columbia''-class boat in FY2021,<ref>{{cite web|url=https://news.usni.org/2020/05/19/report-columbia-class-nuclear-ballistic-missile-submarine-program|title=Report on the Columbia-class Nuclear Ballistic Missile Submarine Program|website=USNI News|date=20 May 2020|access-date=8 November 2022}}</ref> though it is not expected to enter service until 2031.<ref>{{cite web| url = https://media.defense.gov/2018/Feb/02/2001872886/-1/-1/1/2018-NUCLEAR-POSTURE-REVIEW-FINAL-REPORT.PDF| archive-url = https://web.archive.org/web/20180202200026/https://media.defense.gov/2018/Feb/02/2001872886/-1/-1/1/2018-NUCLEAR-POSTURE-REVIEW-FINAL-REPORT.PDF| url-status = dead| archive-date = 2 February 2018| title = Nuclear Posture Review - Final Report|publisher=media.defense.gov|date=February 2018|access-date=8 November 2022}}</ref><ref name="senedia.org">{{cite web |url=http://www.senedia.org/wp-content/uploads/2014/09/Ohio-Replacement-Program-Defense-Innovation-Days-5-Sep-2014-Final.pdf |title=SENEDIA Defense Innovation Days |date=5 September 2014 |website=Senedia.org |access-date=20 August 2016}}</ref>

Perry]], the director of undersea warfare on the [[Chief of Naval Operations]]' staff, discussed the ''Columbia''-class program, and also touched on the possibility of finding ''Ohio''-class boats that had sufficient remaining nuclear fuel and were in good enough material state to be given a further extension to their lives.<ref name="2022-11-03_DN">{{cite web|url=https://www.defensenews.com/naval/2022/11/02/us-navy-wants-to-avoid-shortfall-of-nuke-armed-subs-in-2030s/|title=US Navy wants to avoid shortfall of nuke-armed subs in 2030s|publisher=defensenews.com|date=2 November 2022|access-date=8 November 2022}}</ref>
