Submarines of Australia

Submarines of Australia are the undersea warfare vessels operated by the Royal Australian Navy since the early 20th century. They have participated in regional operations, strategic deterrence planning, and exercises with partners such as the United States Navy, Royal Navy, and Royal Canadian Navy. Australia's submarine community has evolved through acquisition from foreign builders, domestic maintenance at national shipyards, and strategic reviews including the 2009 Defence White Paper and the 2020 Defence Strategic Update.

History

Australia's submarine history began with the acquisition of early boats after federation alongside commitments to the Imperial Defence Committee and ties to the Royal Navy. During the First World War and Second World War, Australian submarines operated in concert with allied fleets such as the Royal Navy and the United States Navy, influenced by global naval conferences like the Washington Naval Treaty and the London Naval Treaty. Post-war restructuring saw ties to shipbuilders in Britain, United States, and later to yards in Germany and Japan, framed by national defence reviews like the Defence of Australia Policy and inquiries such as the Dibb Review. Strategic partnerships forged in forums like the Five Eyes intelligence alliance and exercises such as RIMPAC and Talisman Sabre shaped doctrine and basing decisions.

Classes and Types

Australia has operated a variety of classes procured from foreign builders and adapted by local naval architects at facilities including Cockatoo Island Dockyard and Garden Island. Notable classes include early diesel-electric designs influenced by Holland-class concepts, the Porpoise class and the Oberon-class submarine built by Vickers and operated during the Cold War. The Collins-class submarine program, built by ASC Pty Ltd in partnership with Kockums and later supported by BAE Systems, represented indigenous sustainment and modification efforts. Planned future programs have referenced designs from France (e.g., Scorpène-class submarine) and partnerships with United States and United Kingdom firms under initiatives linked to the AUKUS security partnership.

Operational Service

Australian submarines have undertaken patrols, intelligence collection, and cooperative operations with navies such as the United States Pacific Fleet, Royal Navy, and Japan Maritime Self-Defense Force. During the Cold War, Oberon and Porpoise class boats supported alliance anti-submarine warfare training alongside units from the Royal Canadian Navy and the Royal New Zealand Navy. Collins-class boats have been deployed on operations aligned with regional security tasks addressing contingencies in areas proximate to South China Sea, Timor-Leste, and the Indo-Pacific theatre, often participating in exercises like Cobra Gold and Malabar. Operational challenges prompted reviews including the Jenkins Review and capability upgrades involving contributors such as Raytheon and Thales Group.

Bases and Infrastructure

Key submarine support infrastructure has been concentrated at facilities such as HMAS Stirling on Garden Island, Western Australia and HMAS Platypus in Sydney Harbour. Maintenance and sustainment have relied on yards including Cockatoo Island Dockyard, Williamstown Dockyard, and the ASC shipyard at Osborne Naval Shipyard. Logistical and training hubs have involved institutions like the Australian Defence Force Academy for officer training, the Australian Submarine Agency arrangements for AUKUS-related programs, and collaboration with allied bases including Pearl Harbor and Diego Garcia for forward operations.

Procurement and Future Programs

Procurement has been shaped by bids and national reviews such as the First Principles Review, the 2016 Defence White Paper, and announcements under the AUKUS partnership between Australia, United Kingdom, and the United States. The transition from Collins-class sustainment to future nuclear-powered options prompted negotiations involving General Dynamics Electric Boat, Naval Group, Babcock International, and Lockheed Martin. Domestic industry participants include ASC Pty Ltd, Boeing Australia, and Thales Australia for systems integration, workforce development, and local build components at yards like Osborne Naval Shipyard and regulatory oversight by the Department of Defence. Future procurement decisions are expected to address interoperability with allies, basing at HMAS Stirling, and implications for regional partnerships involving states such as Japan, India, and South Korea.
