Ghost Shark Extra-Large Uncrewed Underwater Vehicles’ Payload Bay Seen For First Time

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.

Matthew Buckley; Professor Tanya Monro, AC Chief Defense Scientist; and Pat Conroy, Minister for Defense Industry, stand in front of a Ghost Shark, with payload bay open, at the Anduril Australia factory in Sydney, New South Wales.

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.

Airbus Details Progress With Lakota Connector Uncrewed Cargo Helicopter

Airbus U.S. Space and Defense has been actively developing and iterating the technology for its Lakota Connector, an uncrewed, autonomous variant of the multi-mission UH-72B Lakota helicopter. This includes testing under Team Lakota Connector, that has brought together Shield AI, L3Harris Technologies, and Parry Labs in a prototyping phase for the U.S. Marine Corps.

TWZ’s Jamie Hunter spoke with Carl Forsling from Airbus U.S., at the AUSA 2026 trade event in Washington D.C. A former U.S. Marine Corps CH-46 Sea Knight and MV-22 Osprey pilot, Forsling explained the requirement for uncrewed logistics in contested theaters, and what’s next for Team Lakota Connector.

Navy Orders 30 Drone Ships To Finally Advance Its ‘Medium’ Uncrewed Vessel Ambitions

The Navy has announced plans to buy 30 new drone boats, 10 from each of three companies, under its Medium Unmanned Surface Vessel (MUSV) program. The deals are an important step forward for the Navy’s latest attempt to field larger USVs after years of setbacks and shakeups, but it remains to be seen when these new capabilities might actually become operational.

Galliano Marine Services, Huntington Ingalls Industries (HII), and Saronic Technologies each received so-called Other Transaction Authority (OTA) agreements in relation to the MUSV program today. OTA is a contracting mechanism designed to support rapid prototyping and other research and development work without having to use more traditional and often lengthy processes.

The awards “mark a significant step forward in translating the strategic vision into a tangible fleet capability,” Chris Miller, the Navy’s Acting Direct Reporting Portfolio Manager for Robotic and Autonomous Systems (DRPM RAS), told TWZ and others at a media roundtable earlier today. “Each agreement is for the procurement of 10 MUSV at an average procurement cost of $40 million per vessel.”

Saronic and HII submitted their Marauder and Romulus designs, respectively, to the MUSV Phase I competition. Galliano Marine Services, which does business as Edison Chouest, does not appear to have announced its entrant publicly. At a unit cost of $40 million, the total price tag for 30 MUSVs, regardless of type, would be $1.2 billion.

“Production will begin immediately at shipyards in Loreauville, Houma, and Franklin, Louisiana, with deliveries starting as early as the fourth quarter of [Fiscal Year] 2027,” Miller added.

To take a step back quickly, the Navy has used a variety of definitions for what qualifies as a “medium” USV over the years. It’s also important to note that the Navy already fields several speedboat and jet ski-type USVs operationally that are capable of performing various different missions, including employment as one-way attack munitions.

Threshold MUSV program requirements the service put out in March included a range of at least “2500 nm [nautical miles] at 25 knots while carrying a 25 MT [metric ton] load on the payload deck in NATO STANAG 4194 Sea State 4.” Sea State 4 is characterized by wind speeds of 17 to 21 knots and wave heights between four and eight feet, per that NATO standard. The MUSVs also had to be able to carry forty-foot equivalent units (FEU) containerized payloads and refuel at sea at a rate of “2,000 gallons per minute of fuel through deck connections.” Various other operational and sustainment requirements were laid out at that time, as you can read more about here.

The OTAs announced today were awarded “following successful at sea testing” under Phase I of the MUSV program, according to a press release the Navy put out today. A total of seven companies competed in this initial phase, with the others being Birdon, Leidos, PacMar Technologies, and Sea Machines. That work was conducted under an earlier round of OTAs.

“The testing evaluated, among other things, the vessel’s ability to see and understand the surrounding maritime environment, how well the vessels navigated autonomously according to the international regulations for preventing collisions at sea, and the vessel’s ability to conduct a long-duration mission,” the Navy’s Miller said at the roundtable earlier today. “The demonstrations had to prove that the designs were mature enough to meet the Navy’s operational standards and our requirements.”

In terms of the long-duration mission requirements, “the test was that they had to be able to execute [over] roughly 26 hours and over 360 nautical miles with only a single input during that time from a C2 [command and control] station allowed,” Milleter further explained. “So, it basically demonstrated that the vessel could run for an excess of 24 hours at an extended range with very minimal input from the actual operator from a C2 station. This provided basically our input and our ability to assess how truly autonomous the functionality was of the platforms.”

Overall, the OTA awards “were based on the optimal mix of autonomy, performance, design, production schedule, and cost,” he added.

The MUSV Phase II contracting notice outlines additional parameters, including that submitted designs cannot be more than 295 feet (90 meters) long or displace more than 5,000 metric tons. The USVs also have to be able to accommodate “at least 2x Twenty-foot Equivalent Unit (TEU) [containerized payloads] weighing 24,000 kg each and consuming 25 kW each” and be “capable of executing multi-day unmanned operations of at least 10 days.” The drone boats need to be “operable in NATO STANAG 4194 Sea State 4 and survivable in Sea State 6,” as well. The full lists of threshold requirements and desired attributes are reproduced below.

USN

In addition, “to be considered for this Call for Solutions, the proposed MUSV must be ready for operational demonstration at the time of solution submission,” according to the Phase II contracting notice. “An MUSV requiring substantial modifications for the production platform compared to the as-demonstrated platform will not be considered.”

“The Phase II solicitation allows entrants to compete and existing vendors to submit updated product blocks and modular payload configurations,” Miller, the Acting DRPM RAS, said today. “Testing evaluations will begin as early as November 16th, and proposals will be assessed on a continually rolling basis over the next five years.”

Miller also drew attention to the elimination of the speed and at-sea refueling targets previously outlined in Phase I.

“What we learned from Phase I is that as you increase the speed requirements and some of these other things, it does present certain challenges for industry,” according to Miller. “So I’m trying to actually find the sweet spot in the market where there is healthy competition, and there’s opportunities, and we can have more things that potentially are dual use, both military and civilian.”

So far, the Navy has only offered limited insights into exactly what specific mission sets it wants the MUSVs to perform, even initially.

The “MUSV Phase I requirements were closely tailored to fulfill operational requirements for a specific mission set focused on demonstrated ability to carry containerized payloads while meeting specific vessel performance requirements for speed and range,” Miller said during today’s roundtable. “However, there is an ever-increasing demand signal that we must be ready to meet. To ensure scalability across the broader mission sets and to support our joint force, we issued a formal call for solutions for MUSV Phase II integration and testing.”

He also stressed that the modularity of the designs being acquired now would allow for the continued evolution of their capabilities as time goes on.

With the focus on containerized payloads, “honestly, inside you could have a sensor, you could have repair equipment for ships,” Rebecca Gassler, who was the Navy’s Portfolio Acquisition Executive for Robotic and Autonomous Systems (PAE RAS) until August, also told TWZ and other outlets back in March. “You could have any number of payloads inside those, and you basically are able to just swap them on.”

In announcing the new OTAs today, as well as discussing the Phase II MUSV plans, the Navy also highlighted continued opportunities for the other companies that had been involved in Phase I.

“Leidos, PAC MAR, and Sea Machines were determined to complete the project provided for in their prototype other transaction agreement and will receive a $15 million award as part of the previously established terms of the prototype OTs,” the Navy’s MUSV announcement today adds. “Alongside the OT awardees, will be accepted onto the Drones.mil hosted Maritime Marketplace, where they are now eligible to receive follow-on production agreements from authorized acquisition authorities across the DOW [Department of War].”

Birdon did not complete the required testing. Based on the terms of the Phase I OTAs, Galliano, HII, and Saronic will also receive $15 million awards and be included in the marketplace. The aforementioned Phase II CFS is intended “to expand its acquisition pipeline through a Maritime Marketplace to broaden offerings and satisfy future MUSV mission sets,” as well, per the Navy.

The Navy stressed the importance of this open-ended “marketplace” model as a way to accelerate the acquisition process when it first outlined the MUSV program to the public back in March, as you can read more about here. Just last week, the service also established a new Robotic and Autonomous Systems Warfighting Development Center (RASWDC) to serve as a focal point for “the development, operational integration, and employment of robotic and autonomous systems (RAS) across the maritime domain,” to include the MUSV effort.

The Drones.mil marketplace also extends to all branches of the U.S. military and beyond just USVs. Miller today did highlight the potential for possible cooperation with other services on drone boat efforts through this framework. He also said the Navy might be willing to consider additional acquisition strategies, including leasing uncrewed platforms, in the future.

Larger USVs have long been seen as key to bolstering the U.S. Navy’s overall operational capacity above the waves, and doing so in a cost-effective and rapidly producible manner. They are also viewed as central to enabling new, more distributed concepts of operations designed to help expand operational coverage and reduce the vulnerability of crewed ships, especially in any future high-end fight in the Pacific with China.

“Unmanned technology is redefining operations and providing our combatant commanders with unprecedented scale, persistence, and risk tolerance,” the Navy’s Miller said at the roundtable.

At the same time, as mentioned, the Navy has attempted to acquire operational fleets of larger drone boats in the past without success. Today, the service’s capabilities in this regard remain limited to a pocket force of still largely experimental optionally-crewed designs.

Since the Navy first unveiled it in March, MUSV has already faced certain hurdles. This includes a major leadership shakeup in August that saw PAE RAS Rebecca Gassler, the first person to ever hold that post, removed from her post after just eight months for reasons that are still not immediately clear.

In July, it also emerged that Blue Water Autonomy and Saildrone had filed suit against the Navy over being left out of Phase I of the MUSV competition. The companies alleged that the service did not follow its own selection criteria. That lawsuit is still ongoing. Blue Water Autonomy, among others, had also previously made investments in response to requirements the Navy had laid out for a previous effort called the Modular Surface Attack Craft (MASC) last year. The MUSV program has now fully supplanted MASC.

In speaking at the roundtable today, Miller acknowledged potential budget limitations and other hurdles that could still impact MUSV going forward. “I’m trying to be prepared depending on where that demand goes,” he said.

As said at the start, today’s MUSV announcement is an important new step forward for the Navy’s efforts to acquire fleets of larger USVs, but the service still has to transition these efforts into operational realities.

Torpedo Fired From Uncrewed Submarine For The First Time By U.S., U.K.

A British Excalibur uncrewed underwater vehicle (UUV) has fired a U.S. Mk 48 heavyweight torpedo in what is said to be a first-of-its-kind test for both countries. Though just a proof-of-concept so far, this is a significant new step for the United States and the United Kingdom toward future operational fleets of armed UUVs.

The U.S. Navy and the Royal Navy conducted the armed UUV test at the British Underwater Test & Evaluation Center (BUTEC), a maritime test range in Scotland, on September 13. Personnel from the Pentagon’s Defense Innovation Unit (DIU) and the Naval Undersea Warfare Center Keyport Division (NUWC Keyport), as well as unspecified industry partners, also took part, per a U.S. Navy press release.

The test was also carried out under the umbrella of Pillar 2 of the trilateral Australia-United Kingdom-United States (AUKUS) defense cooperation agreement, which was first announced in 2021. AUKUS’ Pillar 2 covers a wide range of advanced technology cooperation, with particular focus on uncrewed platforms and autonomy. Pillar 1 of the agreement centers on support for Australia’s establishment of a nuclear submarine force.

For the September 13 test, the Mk 48 torpedo was slung under the Excalibur UUV. The nearly 40-foot (12-meter) long, 19-metric-ton submersible drone has a large internal payload bay, but it is reportedly not large enough to accommodate the Mk 48, which is the standard heavyweight torpedo in U.S. Navy service today. The 19-foot-long, 21-inch-diameter weapon has been successively upgraded over the years to expand its capabilities and improve its resistance to enemy countermeasures.

The Royal Navy officially unveiled Excalibur, which was developed by U.K.-based MSubs under Project Cetus, last year. The external torpedo launch capability was the result of two additional efforts, called Project Broadsword and Trial Iron, according to the U.S. Navy release.

The September 13 test “successfully validated the mechanical, electrical, and software integration of a U.S. kinetic payload onto an allied autonomous vessel, proving that allied forces can rapidly achieve weapon interchangeability,” the Navy’s release adds. “Approved in February 2026 by the Department of the Navy Rapid Capabilities Office (DONRCO), the project was executed in less than seven months.”

How the Excalibur UUV was controlled during the test and whether the torpedo was launched at a test target of some kind are unknown. TWZ has reached out for more information.

“BROADSWORD is a great example of how AUKUS Pillar II drives interoperability in across the alliance. Demonstrating the launch of a US torpedo from a UK extra-large unmanned underwater vehicle (XLUUV) is an important early step in developing lethality in our undersea autonomous systems,” U.S. Navy Vice Adm. Robert Gaucher, Director of Submarine Programs, did say in a statement. “We look forward to continuing to leverage the AUKUS partnership to keep pushing the potential warfighting advantages of unmanned undersea systems.”

“This successful test marks a historic first for allied undersea warfare,” U.S. Navy Adm. Daryl Caudle, Chief of Naval Operations, also said in a statement. “Proving that we can seamlessly launch a U.S. heavyweight torpedo from a Royal Navy autonomous underwater vehicle validates our shared vision for true interchangeability.

“This is a really important moment in our journey towards building a hybrid navy, which is where the Royal Navy will sail with crewed ships and submarines alongside uncrewed and autonomous vessels,” Luke Pollard, U.K. Minister of State for Defence Readiness and Industry, separately said in an interview with LBC radio. “It is a substantial increase in our lethality, to show that torpedoes can be fired not just by the Astute class hunter-killer submarines that we have in the Royal Navy, but also now by our uncrewed systems.”

The U.S. Navy and the Royal Navy employ various tiers of UUVs operationally today, but primarily for mine-sweeping and reconnaissance and surveillance missions. Future fleets of submersible drones capable of carrying out attacks on other vessels will create entirely new operational possibilities. Operated closely together with crewed surface warships and submarines, torpedo-toting UUVs could be sent ahead into riskier environments and offer an immediate option for engaging any threats they might find. Even a bigger UUV like Excalibur would also be more challenging for opponents to spot and track than a traditional attack submarine.

Excalibur is also in a category of larger and more capable submersible drones that offer significant endurance and higher degrees of autonomy. Adding in the ability to launch torpedoes, in turn, then opens the door to new concepts for employing these UUVs in groups more independently of crewed companions. In the future, for instance, armed Excaliburs or similar UUVs might be deployed to a particular maritime choke point to not just monitor for enemy movements, but actively hold them at risk.

In addition, in general, UUVs offer a way to expand total undersea warfare capacity in a more cost-effective manner compared to acquiring and fielding more traditional submarines. The ability to have more presence below the waves at a lower price point also translates to more persistence across large areas, something that could be especially valuable across the broad expanses of the Pacific, as well as other bodies of water globally. This presents additional targeting challenges and uncertainty for opponents.

“In securing the North Atlantic, especially against those nations that wish to do us harm, like Russia, the ability for us to now say it’s not just where our submarines are that you need to worry about – it is about how we create greater deterrence and question marks in the eyes of our adversary, with uncrewed systems there as well,” U.K. Minister Pollard said in speaking with LBC.

Pollard’s remarks here speak to particular considerations the British government is faced with just in its backyard. This includes the so-called Greenland-Iceland-United Kingdom (GIUK) Gap, which is the main path through which Russian Navy submarines transit to and from bases in the northwestern end of that country and the Atlantic proper. There is also the English Channel and the nearby Baltic Sea. The Royal Navy has limited capacity with its crewed submarines to monitor this and other critical regional chokepoints. UUVs could then help take pressure off its fleet of just five (of a planned seven) Astute class submarines, helping free those boats up for the myriad other missions they are tasked with, including carrier escort and special operations support.

“By converting commercial and allied uncrewed undersea hulls into high-end strike assets, the partnership drastically alters the cost-exchange ratio in contested maritime environments,” the U.S. Navy’s press release today notes, as well.

There are still many questions still to be answered about future larger UUV operations, including just how they will be deployed and recovered. Video the U.S. Navy released today shows that the torpedo-armed Excalibur was launched into the water in Scotland using a commercial truck-mounted crane. U.S. shipbuilders Huntington Ingalls Industries (HII) and General Dynamics National Steel and Shipbuilding Company (NASSCO), among others, have been working on new options for launching and retrieving larger drone submersibles from surface warships. External carriage on the hulls of ships and/or submarines might also be an option in the future.

Additional torpedo and other munition options for UUVs beyond the full-size Mk 48 could also be on the horizon. The U.S. Navy has invested heavily in compact and lightweight torpedo designs that could be well suited for employment from underwater drones like Excalibur.

The U.S. Navy says it is working with its international partners on another similar UUV capability demonstration, but this time involving an Anduril Dive-XL, under what is dubbed Project Cutlass. This effort “will tackle advanced payload integration data, command and control architectures, and tactical employment scenarios to further mature uncrewed undersea capabilities,” according to the U.S. Navy’s release.

The Royal Australian Navy is already in the process of acquiring and fielding a militarized version of the Dive-XL, called Ghost Shark. It’s also worth noting that the Dive-XL evolved from the earlier Dive-LD design. The Dive-LD is in at least limited operational U.S. Navy service now, a fact that was revealed by Iran’s capture of one of these submersible drones earlier this month, as you can read more about here.

The U.S. Navy is also continuing to push ahead with plans to field a force of Orca XLUUVs from Boeing. In August, the service announced that an Orca had conducted a 1,000-nautical-mile transit in the Pacific the preceding month as part of the ongoing development of that design.

Other countries are pursuing larger UUVs, as well. China has been making strides in this regard and is in some ways ahead of other competitors globally.

Excalibur’s ability to launch a standard Mk 48 heavyweight torpedo is already an important show of progress now toward a shared goal of a future underwater ecosystem that includes submersible drones that are able to attack other vessels.
