Australia is spending up to A$368 billion, call it US$235 billion, on a fleet of nuclear-powered submarines, and the first boat to actually fly an Australian flag won’t arrive until the early 2030s. The ones built in Australia are a 2040s project. So you’d figure the Royal Australian Navy’s underwater ambitions are parked in a waiting room for the next decade. Apparently nobody told the robots.<\/p>\n
In April, the Navy stood up a unit it has never had before, one that operates nothing but uncrewed vehicles, and its headline act is a drone submarine called Ghost Shark. The name is no coincidence either. This is the underwater sibling of the Ghost Bat, the Australian-built AI combat drone<\/a> that just flew its first missions on American soil.<\/p>\n The new outfit is the Maritime Autonomous Systems Unit, or MASU, formally stood up on April 14 under Project SEA 1200, according to Australia’s Department of Defence<\/a>. One day later, Defence confirmed the Navy had taken delivery of production Ghost Sharks, the first of dozens ordered under a A$1.7 billion (US$1.1 billion) contract signed in September. The Sydney factory that builds them scales from low-rate to full production this year. Add it up and you get an odd situation: the cheapest, fastest-moving part of Australia’s naval buildup is already in the water, while the expensive part is still being renegotiated at conferences.<\/p>\n MASU is not a lab or a trials office. It comes with its own Uncrewed Systems Control Centre and a Deployable Vehicle Team, which means the unit can pack up, set up at whatever wharf a mission requires, and operate its vehicles from there. The stated focus is persistent, long-range surveillance and strike, the jobs that historically meant sending a crewed submarine and its sailors somewhere unpleasant for months. The point, per the Navy’s announcement, is to give the fleet “a range of asymmetric options to complement Defence’s existing crewed force,” as Commodore Sutherland put it.<\/p>\n Three machines form the starting roster. Bluebottle, built by Ocius, covers the surface layer, and Canberra clearly likes what it sees: a A$176 million contract signed in March adds 40 more boats and takes that fleet to 55. Speartooth, from Melbourne’s C2 Robotics, is the smaller, cheaper underwater workhorse, and if it sounds familiar, it should. It’s the same drone submarine Australia just handed the U.S. Navy<\/a>, the one that ships inside a standard commercial container. Ghost Shark is the heavy hitter of the three, the vehicle built to disappear for long stretches and come back with answers, or not come back alone.<\/p>\n Anduril Australia builds Ghost Shark on the bones of its Dive-XL vehicle, and analysts file it in the extra-large class, the bracket covering vehicles 33 to 98 feet (10 to 30 meters) long. It runs all-electric and uses what’s called a flooded hull: instead of one big pressurized tube keeping the ocean out, the structure lets water in and seals only the compartments that matter, like propulsion and payload. No crew compartment means no crew-sized engineering problems.<\/p>\n The autonomy runs on Anduril’s Lattice software. Past that, details get thin on purpose. Officials declined to say how far a Ghost Shark can travel or exactly how many Australia is buying when Reuters asked at the contract signing<\/a>, which tells you those numbers are worth protecting. What Canberra has said is that the vehicle handles intelligence, surveillance and reconnaissance, plus strike, at very long range from Australian shores.<\/p>\n The development timeline is the part that should make other procurement offices sweat. Anduril signed the co-development deal with the Navy and the Defence Science and Technology Group in May 2022: A$140 million, three prototypes, three years. The first prototype hit the water in April 2024, a full year ahead of schedule, and all three landed on time and on budget. By September 10, 2025, the government had seen enough and signed the A$1.7 billion production contract covering delivery, maintenance and continued development over five years. Defence Minister Richard Marles called it “the leading capability in the world in terms of a long-range autonomous underwater capability” when he announced the deal, as ASPI’s The Strategist reported<\/a>.<\/p>\n At the factory opening a few weeks later, Minister for Defence Industry Pat Conroy summed the program up as going from “concept to reality in less than three years,” according to Breaking Defense<\/a>, which covered the ceremony. For reference, three years is roughly how long a conventional submarine program spends arguing about the requirements document.<\/p>\n Here is where the story turns into something a car reader will recognize. Just seven weeks after the September contract, Anduril opened a purpose-built Ghost Shark plant in Sydney<\/a>: 7,400 square meters, just under 80,000 square feet, of robotic assembly, AI-driven logistics and gantry tracking, with a custom in-water test tank at the end of the line to verify buoyancy, electrical systems and safety before a vehicle ever touches open water. Strip the navy gray off the press release and you are reading a car plant brochure. The product just happens to dive.<\/p>\n The first production vehicle rolled off that line ahead of schedule on opening day, with delivery to the Navy in January. The supply chain pulls components from more than 40 Australian small and medium-sized companies, the site supports over 150 high-skilled jobs, and the line is configured to build the commercial Dive-XL and Dive-LD variants alongside the military vehicle. Anduril says the factory is also ready to produce Ghost Sharks for allies and partners, pending export approval from the Australian government. Which is the quiet part of this whole setup. Australia did not just buy a submarine. It bought a production line, and production lines are how you get dozens of anything.<\/p>\n The contrast with Australia’s other submarine program is hard to miss. Under AUKUS, the plan is three used Virginia-class attack submarines from the U.S. starting in the early 2030s, then Australian-built SSN-AUKUS boats out of Adelaide from the early 2040s, at a total program cost of up to A$368 billion over three decades. And the plan keeps shifting: at the Shangri-La Dialogue in Singapore on May 30, the three governments swapped the one new-build Virginia Australia expected for a third secondhand boat<\/a> from the existing U.S. fleet. The robot fleet, by contrast, did not need a summit. It needed a factory.<\/p>\n Nobody in Canberra is pitching Ghost Shark as a replacement for a nuclear attack submarine, and it is not one. The official framing is complement: relatively cheap, numerous vehicles doing the persistent, risky work so the crewed boats and their sailors do not have to. But the budget direction is loud. Marles said in April that Australia expects to put A$12 billion to A$15 billion into autonomous systems over the next decade<\/a>, roughly US$8.5 to 10.7 billion. And Australia is reading the same water everyone else is. Germany’s hydrogen-powered Greyshark drone submarine<\/a> is chasing sixteen-week underwater endurance for NATO customers, while China keeps floating submarine designs nobody has seen before<\/a> at a pace Western shipyards cannot match.<\/p>\n What we still do not know about Ghost Shark would fill a classified annex: payloads, range, exact fleet numbers, what strike means in practice. The unit’s motto, per Maritime Technology Review<\/a>, is “We Wait, We Strike,” which is about as much operational detail as anyone is getting. The nuclear boats will still matter enormously when they show up. But Australia just demonstrated you can field an underwater combat capability in under four years if you build it like a product instead of a monument. At A$1.7 billion for dozens, the waiting room suddenly has company.<\/p>\n","protected":false},"excerpt":{"rendered":" Australia is spending up to A$368 billion, call it US$235 billion, on a fleet of nuclear-powered submarines, and the first … <\/p>\nAustralia’s navy now has a unit that only runs robots<\/h2>\n
