New photos provide an interesting first public look inside the payload bay of Australia’s Ghost Shark extra-large autonomous underwater vehicle (XL-AUV), and a glimpse of the highly modular concept at the heart of the Royal Australian Navy’s emerging undersea warfare capability. Australian authorities had said in the past that they plan to use Ghost Sharks to conduct “persistent intelligence, surveillance, reconnaissance and strike” missions, but without any real elaboration.

The photographs were taken during a recent visit to the Anduril Australia factory in Sydney, New South Wales, by Pat Conroy, Australia’s Minister for Defense Industry. They emerged as the Australian government announced new details of payload development for Ghost Shark, the Speartooth large uncrewed underwater vehicle (LUUV), and the BlueBottle uncrewed surface vessel (USV), on October 19. While the announcement described the payloads in very broad terms, the photos plus additional details from the Anduril event reveal a more concrete picture of the missions Ghost Shark is being designed to perform.

The three previously undisclosed payload options include deploying up to 12 sea mines in a mission, leaving supply caches on the seabed, and launching Anduril’s ALTIUS aerial drones for reconnaissance or strike missions.

“Ghost Shark now has teeth, and will have the ability to inflict damage on any potential adversary,” Conroy said.

The payload bay image is significant in its own right. Ghost Shark’s modular design is intended to accommodate different mission-specific systems, allowing the Royal Australian Navy to configure the same underlying platform for different operational requirements. Ghost Shark was designed to be extremely modular, flexible, and readily reconfigurable. As part of this, the overall payload portion can be readily configured in different ways using different-sized modular hull sections. Since the nose and the tail are different pieces, with an expandable section in the middle, there is plenty of scope for different payloads as well.

Seeing the internal bay for the first time provides a more tangible look at that approach than earlier photographs of the submarine’s exterior.

Inside the bay of one of the Ghost Sharks on display, there appear to be cylindrical spacers, formed in segments, rather than operational stores. These spacers, and other areas inside the bay, look as if they are fabricated from plywood or similar. Overall, this means it is not entirely clear if they represent the kind of ballast that would be loaded to take the place of actual payloads during trials, or whether they are part of a mockup.

Of the three payload options, the ability to deploy ALTIUS aerial drones is particularly noteworthy. An underwater vehicle capable of releasing aerial systems could extend a naval force’s intelligence, surveillance, and reconnaissance (ISR) reach beyond the submarine’s own sensors. Depending on the drone variant and mission configuration, it could also provide a means of delivering effects at a distance without putting personnel directly in harm’s way. Other roles could include stimulating enemy air defense networks, perhaps even responding to pop-up air defence threats as they appear and attacking them. The ability to put miniaturized satcom terminals, as well as AI, on small drones also greatly opens up the possibilities for UUV-launched aerial drones.

Which ALTIUS variants the Ghost Shark will be able to deploy has not been publicly disclosed. The models displayed at the Altus factory are all derivatives of the ALTIUS-600 family. Notable versions include the ALTIUS-600 for ISR, as well as the ALTIUS-600M, which is designed for strike missions. As you can read here, the basic drone has an overall weight of between 20 and 27 pounds, depending on its payload, which typically weighs between three and seven pounds. The ALTIUS-600 has a maximum range of around 275 miles and can remain airborne for at least four hours, according to its developer. Unarmed variants of the ALTIUS-600 are designed to be recoverable and reusable, although it is unclear how practical that would be after launch from a UUV.

There is another missing part of the payload puzzle, namely the kinds of capsules that would contain the ALTIUS UAVs for launch from the sub.

The Rheinmetall Asteria 533mm-diameter mine pictured alongside the Ghost Shark is not installed in the vehicle’s payload bay. Its appearance nevertheless provides an intriguing visual counterpart to the newly disclosed mine-delivery capability. According to the manufacturer, the Asteria can be deployed from surface vessels, aircraft, and submarines (normally via torpedo tubes). It can be remotely controlled via an acoustic link and is optimized for the defense of harbors, straits, ports, and other critical areas.

The seabed supply-cache concept points to a different operational role. Ghost Shark could position equipment and supplies underwater for later retrieval, potentially supporting forces operating in areas where conventional resupply is difficult or risky.

The notional supply cache payloads — which are under development by the Defense Science and Technology Group (DSTG) — don’t appear to be on display here. Alex Luck, a naval analyst who closely tracks submarine developments, told TWZ that the cache payloads would likely take the form of capsules, similar in shape to the Asteria mine, but containing whatever supplies need to be moved. It is not immediately clear who would use those caches. One option could be special operations forces, but if the payloads could later rise to the surface, they could be accessed by other forces, too.

It should also be noted that the U.S. Navy and U.S. Marine Corps, in particular, are envisioning future fleets of UUVs and USVs that can carry out kinetic attacks and employ electronic warfare and other non-kinetic effects, as well as emplace mines, providing a direct parallel with the planned mission set for Ghost Shark.

Some of the new payload capabilities are due to be featured in Exercise Maritime Big Play Pacific in San Diego, an AUKUS Pillar II activity focused on advanced maritime capabilities and interoperability. The Australian government says the development effort involves the Royal Australian Navy, Defense Science and Technology Group, the Advanced Strategic Capabilities Accelerator and defense industry.

As we have discussed in the past, Maritime Big Play has links to the U.S. military’s Technology Readiness Experimentation (T-REX) effort and NATO’s Robotic Experimentation and Prototyping Augmented by Maritime Unmanned Systems (REPMUS) exercise series, according to the Pentagon. The U.S. Navy has also been conducting a growing number of large-scale uncrewed-focused maritime exercises and demonstration events in recent years.

Under AUKUS Pillar II, Australia is collaborating with the United Kingdom and the United States on Ghost Shark and its associated capabilities. While Pillar I centers on providing Australia with nuclear-powered submarines, Pillar II focuses on the joint development of advanced defence technologies, including artificial intelligence and autonomous systems.

Exactly how the Ghost Shark will be deployed during the Maritime Big Play Pacific exercise is unclear, but, speaking about the concept of operations, Conroy described examples of it being deployed from a shipping container or launched from the back of a small vessel using a crane. In the past, we have also seen the Ghost Shark loaded in a standard shipping container and transported in a Royal Australian Air Force C-17A Globemaster III airlifter.

Overall, U.S. military wargames have highlighted how uncrewed systems could shape a high-end conflict across the Pacific, particularly a fight over Taiwan. One set of Taiwan conflict simulations found that large swarms of relatively low-cost, networked drones could be decisive in helping locate and attack an invading force, while other wargaming by the Center for a New American Security has highlighted the severe challenges of defending the island against a Chinese assault. Maritime drones could also play a major role: the U.S. Navy has explored submarine-launched aerial drones that act as “flying periscopes,” extending sensor coverage and providing targeting data beyond a submarine’s own reach, while uncrewed underwater vehicles could conduct mine-laying and other asymmetric missions around key maritime chokepoints. The rapid growth and technological advances made by the Chinese submarine fleet also underscore the critical importance of anti-submarine capabilities, in which uncrewed systems can play a major role. Together, these developments underscore the potential value of autonomous systems for the Royal Australian Navy as it prepares to operate across the vast distances of the Indo-Pacific.

Australia’s 2026 National Defence Strategy and Integrated Investment Program allocate up to A$5.8 billion (approximately $4.05 billion) over the decade to autonomous and uncrewed undersea warfare capabilities, including A$1.7 billion (approximately $1.19 billion) for a new fleet of Australian-designed and built Ghost Shark vehicles.

The newly released imagery and payload details offer the clearest picture yet of how Australia intends to expand Ghost Shark beyond a conventional underwater surveillance role. The next key milestones should provide more details of how the payloads will be integrated into the vehicle, and how they might be deployed in practice.

China's military said on Tuesday it had sent forces to watch a US warship that "illegally" entered waters around a disputed shoal in the South China Sea, while further north in the waterway, Taiwan reported a standoff with a Chinese vessel.

Twelve migrants, including an infant, have died in two separate incidents involving boats travelling from Turkey towards the Greek islands of Lesbos and Samos, prompting investigations into the circumstances of the deaths and the activities of suspected people smugglers.

The incidents occurred on Monday, 19 October, in the northeastern Aegean Sea. Six people died when a speedboat collided with a Greek coastguard vessel near Lesbos, while another six were killed after a separate boat overturned north of Samos.

The deaths coincided with the publication of new figures from the European Border and Coast Guard Agency, Frontex, showing that irregular crossings into the EU fell by almost one-third during the first nine months of 2026.

According to the latest border monitoring figures, approximately 91,000 irregular crossings were detected between January and September, although the eastern Mediterranean remained the busiest migration route into the Union.

Two incidents under investigation

According to information released by the Greek authorities, the first fatal incident occurred near Agrilia on Lesbos when a speedboat carrying migrants struck a coastguard patrol vessel before overturning.

Six people died, while eight survivors were taken to hospital. The authorities subsequently arrested a 37-year-old Turkish national, identifying him as the suspected operator of the migrant boat.

Greece’s Maritime Affairs Minister Vassilis Kikilias said the available evidence indicated that the speedboat had struck the left side of the coastguard vessel. The precise circumstances remain under investigation.

In the second incident, approximately four nautical miles north of Samos, a boat reportedly overturned after making a sudden manoeuvre while being pursued by the coastguard.

Five men and one woman died, while 14 people were rescued. An Iranian national was arrested on suspicion of involvement in migrant smuggling.

The arrests do not establish criminal responsibility, and the circumstances surrounding both incidents remain subject to investigation.

Greek authorities have attributed the dangers of the crossings to trafficking networks operating between Turkey and the Aegean islands. The government has reiterated its policy of pursuing smugglers and restricting unauthorised maritime arrivals.

Fewer crossings, continued fatalities

Frontex recorded approximately 31,800 detections along the eastern Mediterranean route during the first nine months of this year, representing a decline of around 15 per cent compared with the equivalent period in 2025.

Across the European Union’s external borders, the agency reported an even larger reduction, with overall detections down by almost one-third.

The Central Mediterranean route experienced a particularly substantial fall, while the Western Mediterranean recorded an increase, reflecting changes in departure points and migration patterns.

These figures count detected border crossings rather than individual migrants and do not necessarily capture every unauthorised arrival.

The latest data also have to be considered alongside exceptional developments elsewhere on Europe’s borders. In July, large-scale movements through Spain’s Ceuta enclave created additional pressures on Spanish authorities and raised questions about the application of the EU’s new asylum arrangements.

The eastern Mediterranean figures encompass several routes, including crossings from Libya towards Crete, movements through the Aegean islands and arrivals across the land border with Turkey.

Consequently, the total recorded for the wider region should not be interpreted solely as the number of people arriving on the Greek islands.

Greece remains central to European border policy

Greece has occupied a central position in EU migration policy since the 2015–2016 crisis, when hundreds of thousands of people arrived from Turkey, many travelling onwards through the Balkans.

The subsequent EU–Turkey migration arrangements were intended to reduce unauthorised crossings and establish procedures for returning certain migrants who did not qualify for protection.

Athens has also faced persistent criticism from human rights organisations concerning allegations of unlawful returns at sea and land borders. Greek authorities deny operating an unlawful pushback policy and maintain that their border operations respect domestic and international law.

The EU’s Pact on Migration and Asylum, which entered into application in 2026, has introduced common procedures for screening arrivals, processing asylum claims and managing people who do not have permission to remain.

Its implementation has placed greater emphasis on border identification, biometric registration and cooperation between national authorities and Frontex.

However, the two disasters demonstrate the continued risks associated with maritime crossings, even during a period of declining arrivals.

Investigators must now establish precisely how both boats overturned, whether criminal offences were committed and what occurred during the encounters with coastguard vessels.

The findings will be relevant not only to the prosecutions of those arrested, but also to continuing scrutiny of maritime enforcement along one of the European Union’s principal external borders.
