Australia has announced a major defense investment in underwater drone technology, committing more than US$1.1 billion (€939 million) to build a new fleet of Ghost Shark attack drones aimed at strengthening its naval power.
Defense Minister Richard Marles described the Ghost Shark program as a leap in military technology, calling it one of the most advanced underwater capabilities in existence. While the government has not disclosed the exact number of drones to be produced, officials confirmed that “dozens” are expected to join the navy over the next five years. The first batch is scheduled for delivery in January 2026.
The Ghost Shark drones are being developed domestically and are designed to operate autonomously over long distances. Built with stealth in mind, they will support Australia’s nuclear-powered submarine fleet by carrying out reconnaissance, surveillance, and strike operations in contested waters. Navy chief Mark Hammond explained that the drones can be launched from both shore bases and surface ships, making them highly flexible in deployment.
The timing of this program reflects growing concerns in Canberra over China’s expanding naval presence in the Pacific. Australia has been deepening its defense partnerships through initiatives such as the AUKUS security pact with the United States and the United Kingdom, which also involves sharing nuclear submarine technology.
By investing in Ghost Shark drones, Australia aims to secure an edge in undersea warfare, ensuring its forces maintain operational strength alongside allied navies. Defense leaders have framed the project as a crucial step in safeguarding maritime routes and deterring hostile actions in a region marked by rising tensions.
