Australia Confirms U.S. Access to Upgraded Submarine Shipyard Under AUKUS Deal
Australian Defence Minister says the U.S. will be able to use the renovated Henderson facility as part of the $12 billion upgrade under the trilateral AUKUS agreement
Australia has confirmed that the United States will have access to defense facilities in Western Australia to support the AUKUS nuclear submarine partnership, as Australia proceeds with a sweeping A$12 billion upgrade to the Henderson shipyard near Perth.
The announcement comes amid a formal review of AUKUS by the incoming U.S. administration.
Defence Minister Richard Marles said Sunday that while the Henderson site is primarily being built to sustain Australia’s future submarine fleet, it is “very much a facility that is being built in the context of AUKUS,” and he expects that U.S. nuclear-powered vessels will use its dry docks.
Marles emphasized that the facility’s purpose is to enable maintenance and sustainment in the Indo-Pacific, consistent with allied cooperation.
The investment marks the largest tranche to date in a 20-year plan to convert Henderson into Australia’s central maintenance hub for nuclear-powered attack submarines.
The initial A$127 million upgrade was announced last year, and the full precinct is expected to support construction of landing craft, general-purpose frigates, contingency docking, and depot-level maintenance, with estimates of around ten thousand direct jobs over time.
Prime Minister Anthony Albanese said that before Australia receives its first U.S. Virginia-class submarines, Henderson will host a rotation of U.S. and U.K. vessels, delivering strategic benefits for allies.
The use of the facility by U.S. submarines cements its role in regional deterrence efforts under AUKUS.
The AUKUS pact, signed in 2021 between Australia, Britain, and the United States, envisions Australia acquiring U.S. Virginia-class submarines in the near term and co-developing a next-generation AUKUS-class submarine with the UK.
Despite the ongoing U.S. review led by Pentagon official Elbridge Colby, Australia and its allies have reaffirmed confidence in the agreement’s continuity.
Observers note that the Henderson upgrade signals a significant shift in strategic logistics: by enabling U.S. access to a forward Pacific base, the partnership deepens alliance infrastructure close to key maritime routes.
The move is also viewed as Australia doubling down on deterrence capability amid intensifying great-power competition in the Indo-Pacific.
The financial commitment is seen as a strategic down payment for what may total A$25 billion over the coming decade to fully realize the Henderson Defence Precinct.
As construction moves forward, allied integration in shipbuilding and maintenance will be tested, and the nature of U.S. and U.K. operational use of the facility will become a barometer of the pact’s robustness.
