Australia pledges $2.7 billion to progress nuclear submarine shipyard build

SYDNEY, Feb 15 (Reuters) – Australia said on Sunday it would spend A$3.9 billion ($2.76 billion) to progress construction of a shipyard that will help deliver ​nuclear-powered submarines under the trilateral AUKUS defence ‌pact with the U.S. and Britain.

Announced in 2021, AUKUS is Australia’s largest-ever defence investment and will see U.S.-commanded Virginia-class submarines based in Australia from 2027, several Virginia submarines sold to Australia from ‌around ​2030, and Britain and Australia building ⁠a new class of ⁠AUKUS nuclear-powered submarine.

Australian Prime Minister Anthony Albanese described the A$3.9 billion as a down payment to deliver the new shipyard in Osborne, a suburb of ​Adelaide in South Australia state.

“Investing in the submarine construction yard at Osborne is critical to delivering Australia’s ⁠conventionally-armed, nuclear-powered submarines,” Albanese said ⁠in a statement.

Official projections put the total ​cost of the build at A$30 billion “over coming decades”, he ​said.

Osborne is where Australia’s ASC and Britain’s BAE ‌Systems will jointly build Australia’s fleet of nuclear-powered submarines, the core component of the AUKUS pact. Until that work begins later this decade, the shipyard is where ⁠much of the maintenance is performed on the country’s existing Collins-class submarine fleet.

South Australian Premier Peter Malinauskas said the down ⁠payment would be ‌spent on building enabling infrastructure for ⁠the shipyard. “This is just the beginning,” Malinauskas ​said ‌in the statement.

In December, a Pentagon review ​of the ⁠AUKUS project found areas of opportunity to put the deal on the “strongest possible footing,” including ensuring that Australia is moving fast enough to build its nuclear submarine capacity.
