Australia Arms Ghost Shark Autonomous Submarines With Aerial Drone Swarms and Sea Mines

The Australian government has authorized its new fleet of autonomous submarines to deploy aerial drone swarms and sea mines, transforming the Ghost Shark from a surveillance vessel into a strike platform. Defence Industry Minister Pat Conroy approved the payloads following classified trials, clearing the systems for deployment at the AUKUS Maritime Big Play Pacific exercise in San Diego this week.[1][5]

The newly declassified payload suite includes up to 12 sea mines per sortie, underwater logistics caches, and Anduril’s ALTIUS aerial drones. This integration allows the extra-large uncrewed underwater vehicle to conduct both sea denial and long-range reconnaissance without risking a crewed submarine in contested waters.[1][4]

Recent footage released by manufacturer Anduril Industries demonstrates the aerial deployment sequence. The Ghost Shark surfaces, opens its upper hull doors, and elevates a 12-tube launcher to fire the ALTIUS drones directly from the water, maintaining a low physical profile during the launch phase.[2][3]

"Ghost Shark now has teeth, and will have the ability to inflict damage on any potential adversary," Conroy told reporters at Anduril's Sydney factory. He noted that the system's modularity means potential adversaries must consider that any shipping container at an Australian wharf could hold a fully armed autonomous submarine.[1][3]

Expanding Undersea Denial

The ALTIUS drones provide the Royal Australian Navy with a layered operational capability. Depending on the specific variant loaded into the tubes, a launched swarm can conduct broad-area surveillance, act as electronic warfare decoys to stimulate enemy air defenses, or execute one-way kinetic strikes against surface targets.[2][4]

The ALTIUS family of tube-launched loitering munitions is already a proven commodity in other military domains. The U.S. Army successfully fired the same drone type from an Apache helicopter at the Yuma Proving Ground earlier this year, but launching them from a surfaced submarine introduces new complexities regarding saltwater exposure and wave stabilization.[4]

Operating a drone swarm from an autonomous submarine requires robust, secure communication links. The Ghost Shark must surface, establish a data connection with allied command centers, receive authorization to fire, and then relay targeting parameters to the ALTIUS swarm without exposing its position to enemy electronic warfare units.[2][5]

The capacity to lay 12 sea mines per sortie provides a covert method for choking off strategic maritime transit routes. Because the Ghost Shark operates autonomously and lacks the acoustic signature of a traditional crewed submarine, it can slip into contested straits, deposit its minefield, and egress before adversary sonar networks detect the intrusion.[3][5]

The logistics cache payload, developed by Australia's Defence Science and Technology Group, introduces a different strategic dimension. The Ghost Shark can deposit equipment and supplies on the seabed, allowing special operations forces or other units to recover them later without a surface ship revealing the location.[3][4]

Modular Payload Architecture

The core advantage of the Ghost Shark is its modular payload bay, which occupies the center of the 12-meter hull. Rather than building specialized submarines for different tasks, the Royal Australian Navy can swap the internal modules to configure the exact same vehicle for minelaying, drone launch, or cargo delivery.[2][6]

These capabilities align directly with the AUKUS Pillar II initiative, which focuses on advanced technologies beyond nuclear submarines. Australia, the United Kingdom, and the United States have pledged to develop interchangeable payloads for uncrewed undersea vehicles, ensuring that a British or American module could theoretically slot into an Australian hull.[1][5]

This architecture mirrors parallel procurement efforts in the United States. The U.S. Navy recently selected Anduril's Dive-XL—the commercial baseline that the Ghost Shark is built upon—for its own extra-large autonomous underwater vehicle program, signaling a shared allied approach to undersea warfare and supply chain resilience.[4][6]

The Ghost Shark program represents a $1.7 billion investment by Canberra, with Conroy confirming the contract covers "dozens and dozens" of the autonomous vessels. The rapid development cycle saw the first prototype unveiled in April 2024, moving from concept to armed testing in less than three years.[1][6]

The shift toward heavily armed, uncrewed submarines reflects growing strategic anxieties in the Indo-Pacific. Australia is rapidly expanding its autonomous maritime capabilities to counter China's naval buildup and secure its northern maritime approaches without overextending its limited fleet of crewed Collins-class submarines.[1][5]

By offloading high-risk missions like offensive minelaying and close-in reconnaissance to the Ghost Shark, naval commanders can preserve crewed assets for complex anti-submarine warfare. A mass launch of relatively inexpensive ALTIUS drones could probe contested airspace that would be too dangerous for manned maritime patrol aircraft.[2][4]

Testing and Integration

The newly revealed payloads are currently undergoing operational evaluation in California. The Maritime Big Play Pacific exercise allows the AUKUS partners to test the Ghost Shark's systems alongside other autonomous platforms, validating how these uncrewed assets communicate and share targeting data in a simulated combat environment.[1][5]

The Ghost Shark is not operating in isolation during the Pacific trials. It is networked with the Speartooth, a smaller uncrewed underwater vehicle designed for shallower coastal operations, and the BlueBottle, a solar- and wind-powered surface vessel that can act as a persistent communications relay for the submerged assets.[1][5]

While the 12-tube launcher has been demonstrated successfully, the exact number of ALTIUS drones a single Ghost Shark can carry remains classified. Industry executives indicated the payload bays could also support heavyweight and lightweight torpedoes in the future, though those weapons have not yet been formally approved for deployment.[3][4]

The pace of production is accelerating at Anduril's New South Wales facility. Conroy stated that the autonomous submarines are now rolling off the manufacturing line at an increasing rate, moving the program from the prototyping phase toward operational fleet integration and large-scale deployment.[1][3]

The ultimate success of the Ghost Shark as a strike platform depends on the results of the San Diego trials. If the AUKUS partners can seamlessly share targeting data from the ALTIUS swarms across their respective combat networks, the autonomous submarine will fundamentally alter how the allies contest the Pacific.[2][5]
