This expansion is taking place within the framework of the Aukus alliance which includes the United Kingdom, the United States and Australia and aims in particular to deliver and build nuclear submarines in Canberra to counter the military expansion of China in the Indo-Pacific region.
House maintenance facilities
According to a press release issued by Australian Defense, the expansion of this “defense district” will make it possible to build warships and will be used for the maintenance of nuclear-powered submarines. This defense headquarters will be expanded through Australian financial investment over the next two decades.
These emergency maintenance and depot operations induced by the construction site “will create around 3,000 jobs in Western Australia” alone, as stipulated in the press release. This defense complex would be used to shelter “maintenance and emergency docking facilities for Australia's future conventionally armed nuclear submarines”.
85 million dollars and an optimized industry
Defense Minister Richard Marles announced in a statement that 127 million Australian dollars ($85 million) will be used over three years to make the facilities at the Henderson shipyard more modern, Reuters reports.
“The Henderson Defense District will optimize Australia's shipbuilding and support industry while supporting continued shipbuilding in Western Australia and Australia's nuclear-powered submarine pathway” Defense Minister Richard Marles said in the statement.
For the Prime Minister, Anthony Albanese, this shipyard, which already plays a “critical role in delivering and sustaining Australian Defense Force capabilities”will occasionally strengthen its role in Australian industry.
The Aukus alliance
In addition to being the future maintenance center for the future fleet of nuclear-powered submarines, this shipyard will also be the place where new frigates and new landing craft for the Australian army will be assembled, as reported by Agencia. Nova, a company specializing in information services.
According to the Foundation for Strategic Research, the Aukus alliance, (acronym for Australia, the United Kingdom and the United States) was founded in 2021, consists above all of “rotate deployment of up to five US and UK nuclear attack submarines (SNA) from a port in Western Australia” to strengthen defense ties between the three countries.
The establishment of this tripartite military alliance is expected to cost, according to government estimates, $245.8 billion by 2055. “The investment of tens of billions of dollars will transform Western Australia into a military power,” Western Australia Defense Industry Minister Paul Papalia said in the statement.
