U.S. Navy awards HII $56 million for British and Australian SSN-AUKUS nuclear submarine development.

On October 13, 2026, the U.S. Navy awarded Huntington Ingalls Industries (HII) Newport News Shipbuilding a $56 million contract for engineering and design work supporting the AUKUS nuclear-powered submarine program with the United Kingdom and Australia. The award includes a $35 million option that could raise its total potential value to $91 million, with 88% of execution taking place in Virginia through September 2027. This agreement provides essential Foreign Military Sales support to Australia and the United Kingdom while funding U.S. industry support engineering to accelerate technical integration across the trilateral enterprise.

On October 13, 2026, the U.S. Navy awarded Huntington Ingalls Industries (HII) a $56 million contract for engineering and design work supporting the AUKUS nuclear-powered submarine program, including development of the future SSN-AUKUS attack submarine for Britain and Australia. The award to Newport News Shipbuilding includes a $35 million option, raising its potential value to $91 million, with 88% of work in Virginia and 12% overseas through September 2027, potentially extending to September 2028. It covers submarine design, U.S. technology integration, supplier development, and workforce preparation.

The contract comes as the U.S. seeks to double Virginia-class submarine production to accommodate Australian transfers, the UK expands its shipyard and reactor facilities to construct Dreadnought-class and future SSN-AUKUS submarines at a targeted rate of one attack submarine every 18 months, while Australia prepares to acquire three in-service American submarines before introducing five domestically built SSN-AUKUS submarines from the early 2040s. Newport News Shipbuilding will perform two activities: Foreign Military Sales (FMS) support for the UK and Australia, covering engineering, technology integration, supply chains, workforce development, and digital transformation; and U.S. industry support engineering for SSN-AUKUS.

The $35 million option represents 62.5% of the initial award, although funding allocations between activities and engineering personnel numbers remain unspecified. Newport News is one of two American nuclear-submarine construction yards, shares the Virginia-class construction with General Dynamics Electric Boat, and manufactures major sections of Columbia-class ballistic missile submarines. HII's Mission Technologies division separately manages Australia's Submarine Supplier Qualification program and received a Nuclear Capability Advisory Services contract from the Australian Submarine Agency in December 2025. The latest agreement therefore extends an existing engineering and industrial relationship without assigning Newport News construction of British or Australian SSN-AUKUS hulls.

Expected to displace over 10,000 tonnes submerged, the SSN-AUKUS will be developed from the British SSNR design, with BAE Systems responsible for British development and construction at Barrow-in-Furness, and ASC Pty Ltd participating in Australian production at Osborne, South Australia. BAE received almost £4 billion in October 2023 for design, long-lead procurement, and infrastructure through 2028, including doubling Barrow's manufacturing facilities from 80,000 to 160,000 m². Rolls-Royce Submarines at Derby, for its part, will manufacture complete welded nuclear propulsion systems, supported by Australia's £2.4 billion investment over ten years. The expected PWR3 reactor arrangement will avoid refuelling during the submarine's service life, although displacement, reactor output, shaft power, and submerged speed remain unspecified. Preparations for manufacturing propulsion systems for the first two Australian submarines are underway, with British submarine introduction planned from the late 2030s and Australian deliveries from the early 2040s.

The SSN-AUKUS combat system will use the American AN/BYG-1 architecture, already employed aboard Australia's Collins-class submarines and the U.S. Navy's Virginia-, Los Angeles-, Seawolf-, and Ohio-class. BAE Systems, Raytheon Australia, General Dynamics Mission Systems, and Thales agreed on November 7, 2025, to cooperate on its development, integrating tactical control, weapons management, and information assurance. On March 23, 2026, Washington approved a potential $1 billion support package for the UK, twenty times its previous $50 million ceiling, covering vertical launch tubes, common weapon launchers, software, simulation equipment, and engineering. Each SSN-AUKUS submarine is expected to employ 533 mm heavyweight torpedoes and Tomahawk cruise missiles, although launcher numbers and total weapons capacity remain undetermined.

The common architecture would preserve Australian AN/BYG-1 experience while integrating British sonar, propulsion controls, weapons launchers, and submarine-management systems with U.S. weapons and control interfaces. The U.S. production requirement is considerably larger than the three submarines intended for Australia because Virginia-class construction must also replace retiring U.S. Navy attack submarines. The U.S. Navy requires two Virginia-class attack submarines and one Columbia-class ballistic missile submarine annually, with the Virginia-class target increasing to 2.33 boats to accommodate AUKUS agreements. However, output fell to 1.15 Virginia-class submarines in 2024, only 49.4% of the adjusted requirement, leaving a deficit of 1.18 submarines annually and requiring a 103% production increase. By June 2025, 14 Virginia-class submarines were under contract but undelivered, with schedules two to three years behind earlier targets.

On May 30, 2026, AUKUS partners agreed to transfer three in-service U.S. submarines instead of two operational vessels and one new-build submarine, potentially reducing U.S. attack submarine inventory from 2032 until replacement deliveries between 2040 and 2049. Virginia-class submarines have a planned 33-year service life, making the age and remaining operational life of the transferred hulls important to Australia's AUKUS acquisition schedule. To date, Australia has committed AUD 8.5 billion to its Osborne submarine construction yard, comprising AUD 3.9 billion in February 2026 and an additional AUD 4.6 billion on July 24, a 118% increase over the initial allocation. Yard construction is expected to employ at least 4,000 workers, with another 5,500 direct jobs projected during peak submarine production. A training academy opening in the first quarter of 2028 will accommodate 1,000 trainees simultaneously.

In August 2026, General Dynamics Electric Boat placed a $2 million order with Bisalloy Steels for Australian HY80 submarine-grade steel, manufactured initially by BlueScope and subsequently processed and heat-treated to meet submarine requirements. HY80 has a minimum yield strength of 552 MPa, making material qualification necessary for pressure-resistant submarine structures. Western Australia's Henderson Defence Precinct has separately received AUD 12 billion within an AUD 25 billion ten-year investment framework, while Leidos Gibbs & Cox Australia is designing a floating dry dock for contingency submarine repairs from the early 2030s. In parallel, the UK is expanding its nuclear-submarine industrial base to construct up to 12 SSN-AUKUS attack submarines while completing its four Dreadnought-class ballistic missile submarines.

Approximately £6 billion has been allocated to increase manufacturing capacity and achieve a production rate of one attack submarine every 18 months. BAE Systems plans to begin cutting steel for the first British SSN-AUKUS at Barrow-in-Furness in 2027, with an entry into service expected in the late 2030s; the four Dreadnought submarines are scheduled to replace the Vanguard-class in the early 2030s. In July 2026, London committed another £8.4 billion to Dreadnought construction, including £5.9 billion for BAE Systems and £2.5 billion for its suppliers, supporting sea trials of HMS Dreadnought and HMS Valiant and continued construction of the remaining two submarines. At Derby, Rolls-Royce Submarines is doubling its Raynesway manufacturing site with more than 100,000 m² of additional facilities and 1,170 new positions to increase reactor production for both countries.
