The material will support production and construction of Virginia-class nuclear-powered attack submarines in the United States. The Australian government said the order demonstrates the growing integration of Australian manufacturers into allied submarine supply chains.
The award follows Bisalloy’s qualification to U.S. Navy structural steel standards through Australia’s Defence Industry Vendor Qualification program. The initiative is designed to help Australian companies qualify for work in U.S. submarine programs while strengthening domestic industrial capability.
The qualification process involved Bisalloy, BlueScope, the Australian Submarine Agency and General Dynamics Electric Boat. The U.S. Direct Reporting Portfolio Manager for Submarines also participated in the effort.
BlueScope manufactures the raw steel plate used for the product. Bisalloy then performs the specialized processing and heat treatment required to produce submarine-grade HY80 steel.
The United States is expanding capacity across its submarine industrial base and has identified steel supply as a key industrial priority. Canberra said Australian participation can support that expansion while strengthening resilience across the trilateral AUKUS submarine industrial base.
The initial order will also give Australian industry direct production experience within the U.S. submarine supply chain. The government said this could position Australian companies to compete for further opportunities as AUKUS industrial cooperation develops.
“This is a significant AUKUS milestone and a proud moment for Australian industry,” Australian Minister for Defence Industry Pat Conroy said. “For the first time, Australian-made steel will be used in the construction of US Virginia-class submarines, demonstrating the world-leading capabilities of our manufacturing sector and the growing contribution Australian industry is making to allied defence capability.”
“This is exactly what AUKUS is designed to achieve. With this initial order, the AUKUS program is creating tangible opportunities for Australian industry while lifting their technical standards,” Conroy said.
“It is supporting local workers and businesses, and building the industrial capability that will underpin Australia’s future nuclear-powered submarine enterprise.” The government said the order forms part of its wider effort to expand Australian industrial participation in AUKUS.
The agreement also links near-term Australian participation in U.S. submarine construction with the industrial capability needed for Australia’s own nuclear-powered submarine program. Canberra said the work will support skilled employment while building experience within the country’s submarine industrial base.
