Canberra is moving ahead with infrastructure needed to support its future nuclear-powered submarine fleet, partnering with Gibbs & Cox Australia to design a contingency floating dry dock in Western Australia. The facility will support Virginia-class submarines expected to enter Australian service under the AUKUS security partnership. Designed for emergency repairs, unscheduled maintenance and other short-notice requirements, the dry dock will provide an important sustainment capability before Australia establishes more extensive depot-level maintenance infrastructure. The initiative is part of a broader modernization effort involving HMAS Stirling and the Henderson Defence Precinct, where Australia is expanding its sovereign submarine construction and maintenance capabilities. The planned facility may also be available to other AUKUS partners, subject to national regulations and nuclear safety requirements. Meanwhile, Australian industry has secured another AUKUS-related milestone, with Bisalloy receiving its first purchase order from General Dynamics Electric Boat for HY80 submarine steel. The material will be used for US Navy Virginia-class submarines, marking the first integration of Australian-made steel into the program.
