Britain will lead development of three undersea payloads for AUKUS, with the systems expected to become available across British, Australian and US uncrewed underwater fleets from 2027.

The announcement follows trials in San Diego, while Euronaval 2026 in Paris has brought further developments in autonomous and modular naval systems. Naval Group and the Technology Innovation Institute announced plans to explore underwater vehicle development, while Fincantieri unveiled a new modular vessel design.

The question for industry is how these developments will translate into future procurement opportunities.

Visiongain Top Takeaways

• Industry funding: Three British companies and one US supplier secured a share of £3m, while three Australian companies received A$6.2m in development contracts.
• Future procurement: The Royal Navy has opened preliminary market engagement for Type 93, seeking input from vehicle manufacturers and specialist technology suppliers.
• Euronaval 2026: Naval Group and Abu Dhabi’s Technology Innovation Institute agreed to explore underwater vehicle development, while Fincantieri unveiled a modular surface vessel.

Britain Takes the Lead on Three AUKUS Technologies

On 27 October 2026, the UK Ministry of Defence confirmed that Britain would lead development of three undersea payloads under AUKUS Pillar II, following the launch of the trilateral project in May 2026.

The systems comprise a synthetic aperture sonar, a deployable anti-submarine warfare sensor and a non-kinetic effector.

The sonar will provide detailed underwater imagery, while the deployable anti-submarine warfare sensor will help detect and classify threats. The UK Ministry of Defence has not disclosed how the non-kinetic effector will operate.

AUKUS plans to develop interchangeable national payloads before progressing towards jointly developed and produced systems. This approach could allow specialist equipment to be used across different underwater vehicles, although production volumes and procurement arrangements remain undecided.

AUKUS Funds Undersea Technology Across Allied Suppliers

Four companies were selected in May to share £3m under the AUKUS Maritime Innovation Challenge, focused on improving communication and coordination between underwater systems.

• SEA, based in Frome, UK, demonstrated its Acoustic Deployment Environment Planning Tool during Maritime Big Play.
• Decision Analysis Services (DAS), based in Basingstoke, UK, demonstrated software that helps autonomous underwater vehicles coordinate tasks when communications are disrupted.
• A-2i, a consultancy based in Dorchester, UK, also secured development funding, although details of its individual project have not been disclosed.
• MSI Transducers, based in Massachusetts, US, manufactures underwater acoustic equipment, including sonar transducers and arrays. Its specific AUKUS-funded work has not been publicly detailed.

Australia is supporting similar development. In July 2026, its Department of Defence awarded A$6.2m to BAE Systems Australia, L3Harris Integrated Mission Systems Australia and Mission Systems through the same innovation challenge.

The Australian contracts cover communications between underwater vehicles and command systems, alongside navigation data. Demonstrations are planned by the end of 2026.

The awards give specialist suppliers access to allied development programmes, but do not represent commitments to large-scale equipment procurement.

Maritime Big Play Tests Allied Undersea Systems

October’s Maritime Big Play exercise in San Diego brought together more than 40 government and industry technologies from Australia, Britain and the US.

The UK led the anti-submarine warfare trials, contributing 13 uncrewed surface vessels, four underwater gliders and two anti-submarine warfare targets from six industry partners.

Australia also reported progress integrating payloads into its Ghost Shark and Speartooth underwater vehicles and BlueBottle uncrewed surface vessel.

The modular designs support different missions, including the delivery of supplies, sea mines and uncrewed aerial vehicles. The work is relevant to AUKUS’s wider effort to develop mission equipment that can be adapted to different platforms.

Australia has committed A$1.7bn to acquire a fleet of Ghost Shark vehicles developed with Anduril, providing a separate example of funded national investment in autonomous undersea capability.

Royal Navy Opens Market Engagement for Type 93

The Royal Navy has begun preliminary market engagement for its Type 93 extra-large uncrewed underwater vehicle (XLUUV) and the AUKUS Signature Payload Programme.

The October notice seeks input from vehicle manufacturers, payload developers, autonomy specialists, systems integrators and through-life support providers.

The Navy is initially considering vehicles approximately 12 metres long and two metres in diameter, although alternative designs are welcome.

Potential opportunities extend beyond the platforms themselves to underwater sensors, acoustic communications, mission software, payload integration and maintenance.

The notice is not a production tender. No budget, vehicle quantities or entry-into-service date have been confirmed. Registration remains open during the preliminary engagement programme, giving interested suppliers a route into future discussions.

Euronaval Highlights Wider Naval Technology Investment

Euronaval 2026, held in Paris from 3-6 November, has featured several important announcements in autonomous and modular naval technology.

Naval Group and Abu Dhabi’s Technology Innovation Institute signed an agreement to explore joint development and commercialisation of uncrewed underwater vehicles.

Fincantieri unveiled its 50-metre Multi-Mission Modular Vessel (MMMV), designed to accommodate containerised equipment, including underwater drones and launch-and-recovery systems.

Airbus also announced that the VTOL version of its U010 Aliaca drone had received French defence qualification, clearing it for naval service under an existing contract.

The announcements cover different stages of development, from exploratory cooperation and new vessel designs to equipment cleared for service. They also show that investment in naval autonomy extends well beyond AUKUS.

Market Outlook

Visiongain forecasts the global naval USV/UUV market to grow from US$4.35bn in 2026 to US$11.46bn by 2036, at a CAGR of 10.2%.

The undersea defence infrastructure and security market is expected to increase from US$29.47bn to US$56.75bn over the same period, growing at 6.8% annually.

These are global market forecasts, not estimates of spending on the individual programmes discussed here. Both cover technologies and services relevant to the developments examined in this article.

Visiongain Insight

AUKUS plans to move from interchangeable national payloads to jointly developed systems. That offers suppliers the prospect of serving several allied fleets, but common technical standards will not necessarily lead to common purchasing decisions.

Developments at Euronaval show that investment in autonomous and modular naval technology extends beyond AUKUS, widening both the potential market and competition for suppliers.

The Royal Navy’s Type 93 programme provides an early route for industry engagement. The more important commercial test will be how the three AUKUS partners divide development work, structure future contracts and manage technology transfers.

Those decisions will determine whether specialist suppliers can secure business across AUKUS or remain dependent on individual national programmes.
