Australia to Spend $8 Bln on Nuclear Submarine Shipyard Upgrades
Australia Unveils $8 Billion Submarine Shipyard Upgrade

Australia has announced a significant investment of 12 billion Australian dollars (approximately $8 billion USD) aimed at modernizing and expanding its shipyard facilities. This initiative is part of the country’s preparations for a future fleet of nuclear-powered submarines. Defense Minister Richard Marles emphasized the importance of this investment, which will be allocated over the next decade to enhance the Henderson Defense Precinct in Perth, Western Australia.
Strategic Investment Following AUKUS Pact
The funding for the Henderson shipyard comes in the wake of the AUKUS security pact, a trilateral agreement between Australia, the United States, and the United Kingdom. This pact includes plans for Australia to acquire nuclear-powered submarines, marking a pivotal shift in the nation’s defense capabilities. Under the terms of the agreement, Australia aims to purchase three Virginia-class nuclear submarines from the United States within the next 15 years. Additionally, the government is committed to developing the necessary infrastructure to eventually produce its own nuclear-powered vessels domestically.

Minister Marles outlined that the upgrades to the Henderson shipyard will encompass the construction of secure dry docks specifically designed for submarine maintenance. Furthermore, new facilities will be established for the manufacturing of amphibious ships and the Japanese-designed Mogami-class frigates. This comprehensive modernization effort is expected to bolster Australia’s defense industry and enhance its naval capabilities significantly.
While the initial investment is set at 12 billion Australian dollars, Marles indicated that the total cost of transforming the Henderson shipyard could escalate to as much as 25 billion Australian dollars (around $16.5 billion USD). This ambitious project underscores Australia’s commitment to strengthening its defense posture in an increasingly complex geopolitical landscape.
