Australia to spend $1.1bn on underwater ‘Ghost Shark’ attack drones

Australian Defence Minister Richard Marles says large underwater attack drones have ‘very long range’ of operations.

Australia will spend 1.7 billion Australian dollars ($1.1bn) on a fleet of extra-large underwater “Ghost Shark” attack drones, in a move that officials said would supplement the country’s plans to acquire sophisticated nuclear-powered submarines.

Australian Minister for Defence Richard Marles said on Wednesday that the Ghost Shark autonomous underwater vehicles will complement Australia’s naval surface fleet and submarines to provide “a more capable and more lethal navy”.

“This is a profoundly important capability for the Royal Australian Navy,” Marles said.

“We have consistently articulated that Australia faces the most complex, in some ways, the most threatening, strategic landscape that we have had since the end of the second world war,” Marles said.

The government said it signed the $1.1bn, five-year contract with Anduril Australia to build, maintain and develop the uncrewed undersea vehicles in Australia.

“This is the highest tech capability in the world,” Marles said, adding that the drones would have a “very long range” as well as stealth capabilities.

Australia is in the midst of a major military restructuring, focused on bolstering its long-range strike capabilities in an effort to balance China’s expanding military might in the Asia Pacific region.

Marles also said that Australia was now a leading player in “the world in terms of autonomous underwater military capabilities, and Ghost Shark is capable of engaging in intelligence, surveillance, reconnaissance and strike”.

Dozens of Ghost Sharks will be built in Australia, with opportunities to export to the country’s allies, Australian Minister for Defence Industry Pat Conroy said, adding that the first Ghost Sharks will be in service at the beginning of 2026.

Australia’s Defence Science and Technology Group has said it wants to incorporate autonomous technology into the country’s defence forces because Australia has a vast coastline and up to 3 million square kilometres (1.1 million square miles) of northern ocean that needs to be defended, but only a relatively sparse population.

Separately, Australia plans to build stealth, nuclear-powered submarines with the United Kingdom and the United States under the AUKUS programme over three decades.

But critics of the AUKUS deal in the US have questioned why Washington would sell nuclear-powered submarines to Australia without stocking its own military first.

As a result of the criticism, US President Donald Trump’s administration has put AUKUS under review to ensure it aligns with his “America First” agenda.
