USS Minnesota (SSN 783)

USS MINNESOTA History:

The construction of USS MINNESOTA began under a contract to Huntington Ingalls Industries' Newport News Shipbuilding yard in Virginia, with formal keel-laying held on May 20, 2011. The keel authentication ceremony at Newport News marked the point at which the main structural modules were formally recognized as a single warship, and the event was conducted with the usual involvement of Navy officials and the ship's sponsor, Ellen Roughead, the wife of former Chief of Naval Operations Admiral Gary Roughead. By May 2012, the pressure hull sections had been joined into a complete watertight hull, a key milestone in the construction of any nuclear submarine. Newport News then moved the nearly complete hull to the water for final outfitting in advance of christening.

MINNESOTA was christened on October 27, 2012 at Newport News, during a ceremony in which Ellen Roughead formally named the ship and broke a ceremonial bottle of sparkling wine across the bow. The event, held at the Newport News Shipbuilding yard, recognized MINNESOTA as the tenth VIRGINIA-class submarine and highlighted the link between the North Star State and a highly advanced piece of the U.S. Navy's future undersea force.

After the christening, the boat completed further outfitting and machinery testing alongside at Newport News before proceeding to sea for initial trials in 2013. According to later Russian-language summaries that draw on U.S. Navy reporting, she completed her first phase of sea trials in May 2013, demonstrating propulsion, basic maneuvering and key combat systems. On June 6, 2013, Huntington Ingalls Industries delivered MINNESOTA to the U.S. Navy almost eleven months ahead of the original schedule, making her the last of the Block II VIRGINIA-class boats and an example of the maturing construction program at Newport News.

After post-delivery preparations she was commissioned into active service on September 7, 2013, in Norfolk, Virginia. Captain Brian Tanaka, who had led the crew through construction and trials as the pre-commissioning commanding officer, took her into commissioned service and would remain in command for more than four years. Immediately after commissioning, USS MINNESOTA's career took an unexpected turn. During post-delivery work at the General Dynamics Electric Boat yard in Groton, Connecticut, inspectors discovered a broken pipe joint in part of the reactor plant that carried steam used for propulsion. Investigators determined that the joint had been deliberately altered to make it appear within specification, a serious quality-control issue that also affected at least two other VIRGINIA-class submarines.

Although the defect was not assessed as a direct safety risk to the reactor itself, it could have compromised the plant's ability to deliver steam for propulsion, and the Navy decided to keep MINNESOTA pierside at Groton for a lengthy repair. The Department of Justice opened an investigation into the contractor responsible for the faulty components, and the episode became one of the most widely discussed examples of shipbuilding quality concerns in the U.S. submarine program in the mid-2010s.

From late 2013 through 2015, MINNESOTA remained at Electric Boat in Groton while engineers removed and replaced the defective piping and inspected her reactor plant and related systems. Open sources note that the repair effort lasted more than two years and overlapped with similar remedial work on two sister VIRGINIA-class submarines that had received components from the same supplier. The drawn-out yard period meant that, although commissioned in 2013, the submarine did not immediately join the operational fleet. Instead, her crew focused on maintaining proficiency, supporting the repair work and preparing for the eventual transition to full fleet service once the engineering casualty had been resolved.

On May 27, 2016, after those repairs were completed, USS MINNESOTA finally left the Electric Boat yard and shifted across the Thames River to Naval Submarine Base New London in Groton, Connecticut, to begin the process of working up for operational employment. Assigned to Submarine Squadron 4 under Commander, Submarine Force Atlantic, the boat now entered a more conventional cycle of training, inspections and certifications. Over the next year and a half she conducted local operations out of Groton, including basic submarine warfare training, weapons system checks and tactical development exercises in the western Atlantic, as her crew and systems were brought fully to fleet standards after their prolonged shipyard lay-up.

By late 2017, MINNESOTA was ready for her first operational deployment. Under Captain Brian Tanaka, she deployed from Groton on what Minnesota politicians later described as a "historic first deployment", heading across the Atlantic into the U.S. European Command area of responsibility.

The deployment lasted roughly six months. Public sources do not list precise sailing and return dates, but Navy imagery shows the submarine returning to Naval Submarine Base New London on March 14, 2018, with sailors manning the topside as she came up the Thames River to a pier crowded with families. Official captions describe MINNESOTA as returning from duty in the European Command area, where she carried out missions consistent with the Chief of Naval Operations' maritime strategy in support of national security interests and maritime security operations, broadly understood to include undersea surveillance, anti-submarine warfare and presence missions alongside NATO allies.

Shortly after that first deployment, on April 20, 2018, Tanaka's more than four-year tour as commanding officer ended when he was relieved by Commander Thomas Flaherty III. Under Commander Flaherty, USS MINNESOTA continued to operate from Groton, completing post-deployment maintenance and then returning to the Atlantic training cycle. The submarine's performance during her emerging operational career attracted high-level attention. A letter from the U.S. Secretary of Defense in 2018, later mentioned in media reports, expressed appreciation for MINNESOTA's role in anti-submarine warfare and intelligence gathering in the European theater, underscoring the importance of her undersea work to NATO deterrence at a time of heightened concern about Russian submarine activity in the North Atlantic.

In mid-2019, MINNESOTA left Groton again for what Navy sources later described as her second overseas deployment, this time to the U.S. Sixth Fleet area in the eastern Atlantic and Mediterranean Sea. During this deployment the boat operated with U.S. and allied naval forces on demanding missions that, according to later award citations, included multiple theater anti-submarine warfare operations, simulated combat engagements and intelligence collection against targets of high interest. The submarine also conducted a pioneering logistics evolution at Haakonsvern Naval Base near Bergen, Norway, where on October 18, 2019 sailors from MINNESOTA and Norwegian crane operators worked together to load Mk-48 Advanced Capability torpedoes into the submarine in what the Navy described as the first forward-deployed U.S. submarine weapons-handling event in Norway. That evolution demonstrated that a U.S. fast-attack submarine could rearm at an allied facility in the High North, a significant operational message in the context of increased Russian submarine activity in the Norwegian Sea and North Atlantic.

During the 2019 deployment USS MINNESOTA visited several allied ports. Navy accounts and later historical summaries note port calls to Brest, France; Faslane on the Clyde in Scotland, a key Royal Navy submarine base; Haakonsvern, Norway; and Rota, Spain, where the U.S. maintains an important logistics facility and forward base for destroyers. The combination of operations at sea and port visits reflected a typical modern fast-attack submarine deployment: extended periods of covert patrol interspersed with brief logistics and engagement stops in friendly ports to take on supplies, give the crew rest and deepen links with NATO partners. MINNESOTA returned to Groton on December 20, 2019, just before Christmas, concluding this second overseas deployment under Commander Flaherty.

The Navy formally recognized the boat's performance on that 2019 deployment the following year. On July 9, 2020, Submarine Squadron 4's commodore, Captain Andrew Miller, presented the crew of USS MINNESOTA with the Meritorious Unit Commendation (MUC) on behalf of the Secretary of the Navy, during a ceremony in which Commander Flaherty and his team received the ribbon recognizing the unit award. The citation highlighted the boat's demanding missions in the European Command area between June and December 2019, including multiple theater anti-submarine warfare operations, simulated combat engagements, and the collection of high-value intelligence, as well as the forward-deployed weapons-handling event in Norway. The award placed MINNESOTA in a select group of units singled out as outstanding relative to peers, against the backdrop of increased U.S. and NATO emphasis on undersea deterrence in the North Atlantic following Russia's annexation of Crimea and a general deterioration in European security.

In 2020 and early 2021, MINNESOTA continued to operate from Groton, balancing routine maintenance, training in the western Atlantic and preparation for another deployment with the constraints imposed by the COVID-19 pandemic on port visits and liberty. Open sources do not list specific exercises during this period, but by mid-2021 the boat and crew were ready for extended operations again. On November 26, 2021, the submarine returned to Naval Submarine Base New London after what the Navy described as a scheduled seven-month deployment, during which MINNESOTA steamed more than 45,000 nautical miles while operating under Submarine Squadron 4 in support of the Navy's maritime strategy of protecting national security interests and maintaining maritime security. The homecoming, timed with the Thanksgiving holiday weekend, marked the boat's third major overseas deployment and underscored the tempo of operations expected of modern VIRGINIA-class boats.

Even before that deployment ended, plans were taking shape to shift MINNESOTA's role from the Atlantic to the Pacific. After post-deployment workups, the Navy decided to change the submarine's homeport. In March 2022, MINNESOTA departed the U.S. East Coast and transited to the central Pacific, arriving at Joint Base Pearl Harbor-Hickam in Hawaii as her new homeport. Official reports record her "homecoming arrival" at Pearl Harbor on March 17, 2022, following a change of homeport from Groton. Commander Bradley Bozin, then in command, noted that the crew had recently finished the seven-month deployment and that their successful performance on that cruise was something they intended to carry forward into their new role in the Pacific. From that point, MINNESOTA became part of the Pacific Fleet's attack submarine force while still administratively linked to the Atlantic submarine organization during a transitional period.

Soon after arriving in Hawaii, USS MINNESOTA entered another major maintenance phase. In 2022, she began an extended docking selected restricted availability (EDSRA) at Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNSY & IMF), a comprehensive multi-year refit intended to carry out deep maintenance, modernize systems and ensure long-term material readiness. By mid-2024, U.S. Navy imagery described the EDSRA as having lasted almost twenty-five months, placing its start in spring 2022. During this time the submarine spent much of her time in Dry Dock 2 at Pearl Harbor, with shipyard workers and the crew working side by side to complete complex tasks ranging from hull and propulsion work to electronics and combat-system upgrades. On October 12, 2023, PHNSY & IMF undocked USS MINNESOTA from Dry Dock 2, a major milestone signaling that the most intrusive aspects of the EDSRA were complete and that the boat was returning to the water for the final phases of testing and certification.

Under the leadership of Commander Isaac Pelt, who had assumed command during the Hawaii period, the crew and shipyard team pushed to finish the availability ahead of schedule. Navy reporting later noted that under Pelt's command MINNESOTA undocked two weeks early and completed the EDSRA four weeks ahead of the planned end date, while also achieving one of the highest crew retention rates in the fleet and earning a Retention Excellence Award in 2023.

In June 2024, the submarine began sea trials from Pearl Harbor, with imagery showing her transiting the harbor on June 20, 2024 at the start of post-availability testing. On July 3, 2024, PHNSY & IMF declared the EDSRA complete, returning USS MINNESOTA to the operational fleet. A NAVSEA release later in July highlighted the successful completion of the multi-year maintenance effort.

Almost immediately after rejoining the fleet, MINNESOTA took part in major exercises in the central Pacific. In summer 2024, she participated in the Rim of the Pacific (RIMPAC) 2024 exercise, the world's largest recurring international maritime exercise, held around the Hawaiian Islands from June 27 to August 1, 2024 and involving 29 nations, roughly 40 surface ships, three submarines, 14 national land forces, more than 150 aircraft and about 25,000 personnel. As part of RIMPAC activity, the Chief of Naval Operations and the Master Chief Petty Officer of the Navy visited MINNESOTA to speak with the crew and congratulate them on their successful completion of the demanding EDSRA and return to high-end operations, while also touring other participating ships such as the Royal New Zealand Navy support vessel HMNZS AOTEAROA (A-11).

The exercise provided an opportunity for the submarine to practice multinational undersea warfare tactics, torpedo evasion and coordinated operations with allied surface and air forces in an increasingly contested Indo-Pacific environment.

The next strategic shift in MINNESOTA's career came in late 2024. As part of a broader "strategic laydown" of naval forces in the Indo-Pacific, the Navy decided to forward-deploy a VIRGINIA-class attack submarine to Guam for the first time. On November 26, 2024, USS MINNESOTA arrived at Naval Base Guam at Polaris Point, formally changing homeport from Pearl Harbor to Guam and joining Submarine Squadron 15 as the first forward-deployed VIRGINIA-class boat. The move reflected the U.S. desire to place advanced undersea capabilities closer to potential flashpoints in the Western Pacific, shortening transit times and increasing the flexibility of the submarine force in a region marked by strategic competition with China and enduring concerns about North Korea. A little over a week later, on December 5, 2024, MINNESOTA held a change-of-command ceremony on board Naval Base Guam. During the event, Commander Isaac Pelt turned over command of the submarine to Commander Jeffrey Cornielle. Senior officers praised Pelt for leading the crew through a highly effective EDSRA, completing the availability ahead of schedule, achieving outstanding retention and oversaw the complex homeport shift from Hawaii to Guam, including hosting distinguished visitors from Australia in support of evolving undersea partnerships. Cornielle, arriving from a staff tour with Joint Region Marianas, took command as MINNESOTA prepared for her first operational tasking as a forward-deployed asset under Submarine Squadron 15, alongside four LOS ANGELES-class fast-attack submarines based on Guam.

In early 2025, USS MINNESOTA undertook that first operational tasking as a forward-deployed VIRGINIA-class submarine in the Indo-Pacific. Operating from Guam, she headed south and west into the waters off Australia as part of an evolving pattern of cooperation designed to support the AUKUS security partnership and deepen undersea integration with the Royal Australian Navy. In late February 2025, the Australian Department of Defence announced that a VIRGINIA-class submarine had moored at HMAS STIRLING near Perth for the first U.S. submarine visit to Australia that year, identifying USS MINNESOTA as the visiting boat. While alongside in Western Australia, the submarine supported the U.S. Navy's Submarine Command Course - an advanced training program for prospective commanding officers - and took part in Exercise LUNGFISH, a bilateral tactical development exercise between the U.S. Navy and Royal Australian Navy that focused on undersea warfare in the Indian Ocean approaches.

During the same deployment MINNESOTA also visited Darwin in Australia's Northern Territory, where the crew hosted tours for local officials and participated in community outreach, including STEM-focused engagements with local schools. USS MINNESOTA completed this first forward-deployed tasking by returning to her new homeport at Naval Base Guam on April 14, 2025. A Navy release the following day emphasized that the deployment demonstrated the operational readiness of the boat after her recent maintenance and homeport changes and underlined the contribution that a forward-deployed VIRGINIA-class submarine could make to Indo-Pacific deterrence and alliance cooperation.

As of late 2025, USS MINNESOTA remains in active service as a forward-deployed attack submarine based at Guam, assigned to Commander, Submarine Squadron 15.
