Osborne Submarine Construction Yard

Osborne Submarine Construction Yard

Australia will begin building conventionally-armed, nuclear-powered submarines, the SSN-AUKUS, in Osborne, South Australia by the end of 2030. Construction will be supported by an expansion of the existing Osborne Naval Shipyard Area to support the facilities and infrastructure required to build the first SSN-AUKUS, referred to as the Submarine Construction Yard (SCY).

The preferred site for the SCY is situated north of the existing Osborne Naval Shipyard on the Lefevre Peninsula, approximately 19 km north of Adelaide in South Australia.
