Australia Selects US Firm To Build Shipyard For 10,000-Ton AUKUS Nuclear Submarines
Our take
The selection of a US firm to construct a shipyard in Henderson, Australia, for the AUKUS nuclear-powered attack submarines represents a significant escalation in the geopolitical realignment of the Indo-Pacific region. This project, integral to Australia’s 20-year plan to establish a robust maintenance hub, underscores the commitment of all three AUKUS partners – Australia, the United Kingdom, and the United States – to bolstering naval capabilities in response to evolving security challenges. The scale of the undertaking is noteworthy; a 10,000-ton submarine requires a specialized infrastructure rarely found outside of established naval powerhouses. This investment highlights a strategic shift towards long-term maritime dominance and a concerted effort to counter growing influence in the region. The decision also resonates with broader trends in shipbuilding, as evidenced by India’s recent expansion of Cochin Shipyard [India’s Cochin Shipyard Gets 18 Acres For Rs 5,000 Crore Shipbuilding Facility], demonstrating a global push for increased maritime industrial capacity. Furthermore, the sheer volume of goods moving through ports globally, as exemplified by the Port of Los Angeles’ record-breaking June [Port of Los Angeles Records Busiest June In Its 118-Year History With 1.02 Million TEUs], underscores the importance of naval power in securing trade routes and maintaining regional stability.
The choice of a US firm, while perhaps expected given the technological transfer inherent in the AUKUS submarine program, signals a deepening of US-Australian defense ties. The complexity of nuclear submarine maintenance and repair demands a high level of expertise, and leveraging established US capabilities appears to be a pragmatic approach for Australia. However, it also raises questions about the potential for increased US influence over Australian defense policy and industrial strategy. The long-term implications of this reliance on US technology and expertise warrant careful consideration, particularly as Australia seeks to develop its own sovereign defense industrial base. The shift towards sustainable maritime practices, as highlighted by the World’s Largest Single Green Methanol Bunkering Operation [World’s Largest Single Green Methanol Bunkering Operation Completed At Shanghai Port], also introduces a potential future consideration for the new shipyard: incorporating sustainable practices in its operations and contributing to a greener naval fleet. The environmental impact of shipbuilding and submarine maintenance will undoubtedly become an increasingly important factor in future projects.
Beyond the immediate implications for Australia and the AUKUS partnership, this development has broader regional ramifications. It’s likely to be viewed with concern by China, which has been steadily expanding its own naval presence in the South China Sea and beyond. While Australia’s intentions are framed as defensive, the increased naval capabilities will inevitably alter the strategic balance in the Indo-Pacific. The AUKUS agreement itself has been a source of tension, and the construction of this new shipyard further solidifies the alliance’s commitment to a more assertive posture. The long-term success of this project will depend not only on its technical execution but also on its ability to navigate the complex geopolitical landscape and avoid escalating regional tensions. The integration of data and analytics will be critical to optimizing shipyard operations and ensuring the submarines remain a potent force—a necessity underscored by the increasing need for real-time ocean intelligence.
Looking ahead, the development of this shipyard represents a pivotal moment in Australia’s maritime history. The project’s success will hinge on the effective transfer of technology, the development of a skilled Australian workforce, and the ability to maintain a secure and reliable supply chain. A key question will be whether Australia can successfully balance its reliance on US expertise with its desire to build a truly sovereign defense industrial base. The coming years will reveal the extent to which this ambitious project can reshape Australia's role in the Indo-Pacific and contribute to the evolving dynamics of global maritime power.
Australia has chosen a partnership between U.S. engineering company Amentum and Laing O’Rourke to help build a new shipyard at Osborne in South Australia for the country’s future nuclear-powered submarines.
Australian Naval Infrastructure selected the two companies as its Capability Partner for the project. The yard is expected to build Australia’s future SSN-AUKUS submarines, which are expected to displace about 10,000 tons.
At the same time, Australia is moving ahead with a A$12 billion upgrade of the Henderson shipyard near Perth in Western Australia. Defence Minister Richard Marles said the United States will be able to use the upgraded facility and expects U.S. nuclear-powered vessels to use its dry docks.
The two projects are part of Australia’s effort under the AUKUS partnership with the United States and Britain to develop a nuclear-powered submarine capability.
Amentum to support construction at Osborne
Amentum and Laing O’Rourke will work within Australian Naval Infrastructure’s Integrated Delivery Office under a long-term arrangement.
Their work will include managing nuclear-related parts of the program, overseeing construction and providing safety leadership. They will also coordinate different work packages and work with contractors involved in the project.
One of the main challenges will be coordinating nuclear and conventional construction areas at the site.
The Osborne facility will be Australia’s first dedicated construction site for conventionally armed, nuclear-powered submarines. It will need specialised facilities for assembling, outfitting, testing and commissioning the submarines.
Amentum has experience with nuclear submarine programs, including nuclear licensing and work with independent regulators.
Mark Whitney, president of Amentum Energy & Environment, called the project a “once-in-a-generation national endeavor” and said it could influence Australia’s nuclear capability for decades.
Amentum Australia managing director Kim Katheklakis said the company will provide support in areas including governance, logistics, commissioning and digital engineering. Supply-chain quality will also be part of its responsibilities.
U.S. submarines to have access to Henderson
The Osborne project is being developed alongside the major upgrade of the Henderson shipyard in Western Australia.
Marles said Henderson is mainly being developed to support Australia’s future submarine fleet but is also being built as part of AUKUS. He expects U.S. nuclear-powered vessels to use the facility’s dry docks.
The project is part of a 20-year plan to turn Henderson into Australia’s main maintenance hub for nuclear-powered attack submarines.
Australia announced an initial A$127 million upgrade last year. The Defence Precinct is expected to support the construction of landing craft and general-purpose frigates, contingency docking and depot-level maintenance.
The project is expected to create around 10,000 direct jobs over time.
Prime Minister Anthony Albanese has said Henderson will host U.S. and U.K. vessel rotations before Australia receives its first U.S. Virginia-class submarines.
Australia’s AUKUS submarine plans
The AUKUS agreement was signed in 2021 by Australia, Britain and the United States.
Under the agreement, Australia plans to acquire U.S. Virginia-class submarines in the near term and work with Britain to develop the next-generation AUKUS-class submarine.
Australia plans to build the SSN-AUKUS submarines at Osborne. The submarines are expected to weigh around 10,000 tons and will be nuclear-powered but conventionally armed.
This will give Australia a nuclear-powered submarine capability without nuclear weapons.
Building the fleet will require Australia to develop a skilled workforce, specialised supply chains and regulatory expertise to support nuclear submarine construction and operations over several decades.
U.S. industry and government agencies have already supported workforce development and submarine technology efforts under AUKUS.
Australia expects the AUKUS effort to create thousands of skilled jobs in South Australia. The Henderson project alone is estimated to support about 10,000 direct jobs over time.
The full Henderson Defence Precinct could require around A$25 billion over the coming decade, according to the information provided.
