Australia is advancing plans for a floating contingency dry dock designed to support its future Virginia-class nuclear-powered submarines under AUKUS. Gibbs & Cox, the Australian arm of Leidos, will lead the preliminary design of the facility, which is planned for Western Australia. The dry dock will provide emergency, unscheduled, and short-notice maintenance capabilities before the submarines undergo more extensive depot-level servicing later in the decade. The project is part of Canberra’s broader effort to expand sovereign submarine sustainment infrastructure at HMAS Stirling and the Henderson Defence Precinct. Once operational, the facility could potentially support other AUKUS nations while complying with strict Australian and international nuclear safety requirements. The initiative coincides with another AUKUS industrial milestone, as Australian steel producer Bisalloy secured its first order from General Dynamics Electric Boat to supply HY80 submarine-grade steel for US Virginia-class submarines. Together, the developments demonstrate expanding industrial cooperation and supply-chain integration among Australia, the US, and the UK.
