Australia Injects Another Rp58 Trillion into Nuclear Submarine Ambitions

The Australian government has announced an additional investment of A$4.6 billion (approximately Rp58 trillion) to continue the construction of a nuclear-powered submarine shipyard in Osborne, South Australia. The investment, announced on Friday, will be channelled to Australian Naval Infrastructure, the Commonwealth-owned company managing the construction of strategic naval facilities. The funds are not for purchasing three Virginia-class submarines from the United States but are specifically allocated to continue building the Nuclear-Powered Submarine Construction Yard, a complex where Australia will build its future SSN-AUKUS submarines. The Ministry of Defence stated that the new funding supplements an initial A$3.9 billion investment announced in February 2026, bringing the total federal contribution announced for the yard to A$8.5 billion. The entire construction complex at Osborne is expected to require an investment of around A$30 billion over several decades. Deputy Prime Minister and Defence Minister Richard Marles said the investment is another critical step in building the sovereign capability Australia needs to construct, operate, maintain, and sustain its future submarine fleet. He noted that the ongoing work at Osborne demonstrates that the AUKUS programme is on track and being realised. The planned complex is estimated to be ten times larger than the existing surface shipbuilding facility at Osborne. Around 50 buildings are planned for the site, with the first structure targeted for completion within 12 months. Steel cutting for the first Australian-built SSN-AUKUS submarine is expected before the end of the decade. Approximately 1,100 workers are currently involved in the facility’s construction, with the workforce expected to grow to around 4,000 in the coming years. The government estimates the overall nuclear-powered submarine programme will create nearly 10,000 jobs in South Australia.
