Unmanned Surface Vessels in Europe: Who Builds, What Works

Unmanned surface vessels are in European naval service today, but mostly in one job: hunting mines. Belgium and the Netherlands took delivery of their first two rMCM motherships and the first Exail drone toolbox, including Inspector 125 USVs, between November 2025 and March 2026, and the Royal Navy received its second Thales MMCM autonomous minehunting boat in April 2026. Everything else is younger. Germany’s first Stark-built reconnaissance USV arrived in August 2026, the Royal Navy sent 20 Kraken K3 Scouts to the Gulf, and strike USVs remain demonstrators outside Ukraine, whose Magura, Sea Baby and Seawolf boats set the benchmark the rest of the continent is now chasing.

Why European navies are buying naval drones now

The argument was settled in the Black Sea. A navy with no large warships has used explosive-laden boats to destroy or damage roughly a dozen Russian warships since 2022, at a unit cost that Defense News put at several hundred thousand dollars, below the price of a modern torpedo. On 12 September 2026 a Ukrainian Navy Sargan-3000, fitted with a Kongsberg Protector remote weapon station, sank a Russian attack USV in what Naval News called the first drone-versus-drone engagement at sea. The conclusion for European staffs was uncomfortable: a cheap, expendable hull with a satellite link can impose costs that frigates cannot answer.

The second driver is closer to home. Damaged cables and pipelines in the Baltic and NATO’s Baltic Sentry mission created demand for persistent surveillance that crewed patrol boats cannot sustain. Naval Group’s Seaquest S spent three weeks inside NATO’s Task Force X during Baltic Sentry in 2025, operating alone in weather up to Sea State 5, and Germany’s Seetaube was bought explicitly to close reconnaissance gaps around critical maritime infrastructure. The 2026 Hormuz crisis then gave the Royal Navy a reason to ship its new K3 Scouts and containerised mine countermeasures kit to the Gulf within weeks of delivery.

The third driver is doctrine. In his Fisher lecture on 29 April 2026, First Sea Lord General Sir Gwyn Jenkins described a “hybrid navy” of crewed, uncrewed and autonomous platforms, and the June 2026 Defence Investment Plan backed the Mine Hunting Capability programme with £1.1 billion. Germany’s Kurs Marine strategy pairs each of nine K130 corvettes with two armed USVs. The picture is less tidy on the water: outside mine warfare, most European USVs are demonstrators, rental boats or first-of-class trials craft.

Mine countermeasures: the one segment already in service

Mine hunting went first for practical reasons. The task is dangerous, repetitive and geographically bounded, the sonars and disposal vehicles were already mature, and every major European navy was retiring 1980s-era minehunters anyway. Two multinational programmes define the state of the art, and both put the USV at the centre of a toolbox run from a mothership that stays outside the mine danger area.

Belgium and the Netherlands: rMCM with Naval Group and Exail

The rMCM programme, awarded in May 2019 to Belgium Naval & Robotics, the consortium of Naval Group and Exail, covers 12 motherships of 2,700 tonnes, six for each navy, and around 120 unmanned systems, for a value Janes puts at close to €2 billion over ten years. The Belgian Navy took delivery of the lead ship Oostende in November 2025 and the Royal Netherlands Navy received Vlissingen at Den Helder on 27 February 2026. On 2 March 2026, in Zeebrugge, the consortium handed over the first toolbox: two Inspector 125 USVs, three A18-M autonomous underwater vehicles with synthetic aperture sonar, two T18-M towed sonars, Seascan and K-Ster C disposal vehicles, two Saab Skeldar V-200 helicopter drones and an influence sweep, all run through Exail’s UMISOFT software and, apart from the UAVs, built at Exail’s plant in Ostend.

That is the headline. The operational reality is a programme in its integration phase. Speaking at the Combined Naval Event in June 2026, Commander Pierre Van Engeland, the Belgian Navy’s rMCM programme manager, said the biggest challenge right now is “software integration on board the ship and with the tools”, and set the goal of demonstrating a complete end-to-end mine countermeasures capability from the ship by the end of 2026. Launch and recovery of the AUV from the USV does not yet work up to Sea State 4, so the navy is “working with a man on board the USV” for now, and the Skeldar UAVs are restricted to land-based training pending ship qualification. Nine more ships are under construction at Kership yards in Brittany and Romania. Maturity label: PROCUREMENT, with sea trials under way.

United Kingdom and France: Thales MMCM and the Mine Hunting Capability

The Anglo-French Maritime Mine Counter Measures programme, worth €430 million and led by Thales since 2015, is further along in service but smaller in scale. France received its first serial SLAM-F system in December 2024, a 12-metre USV towing the TSAM sonar, with three two-boat systems planned. The Royal Navy accepted RNMB Ariadne on 18 March 2025, its first “Degree 3” autonomous vessel in the programme director’s words, and RNMB Adventure, the second of four, in April 2026.

Here the money tells the story. In December 2025 Defence Equipment and Support gave Thales a £10 million contract for portable, AI-assisted remote command centres built on its M-Cube mission system and Mi-Map target-recognition software, with scope to grow to £100 million. In July 2026 the ministry committed to three offshore support vessels as motherships, procured with Norway, inside the £1.1 billion Mine Hunting Capability envelope. RFA Lyme Bay was fitted with containerised uncrewed MCM systems in Gibraltar in May 2026 for the Hormuz mission. Maturity label: LIMITED DEPLOYMENT.

ISR, harbour security and submarine hunting: the second wave

The Royal Navy’s Project Beehive shows how fast a small ISR boat can move from order to deployment when the platform already exists. Kraken Technology Group’s K3 Scout, an 8.4-metre craft rated for 55 knots and 650 nautical miles, was ordered in March 2026, 20 boats for £12.3 million, for the Coastal Forces Squadron and 47 Commando Royal Marines. By May the first were bound for the Gulf as unarmed sensor pickets, the service’s first acknowledged operational USV deployment. In July a K3 was dropped from an A400M into the North Sea, and on 28 September 2026 Shield AI ran two K3 Scouts under its Hivemind software off Portsmouth, searching, classifying and escorting a vessel of interest without an operator in the loop. The autonomy layer is becoming the competitive ground, a theme that runs through the wider field of Europe’s Defence AI Companies: Who Is Building What in 2026.

Germany is moving in two steps. The Cyber and Information Domain command christened Seetaube in August 2026, a six-metre Stark Vanta-6 that will spend the coming months on trials as a reconnaissance node in the Baltic, and in September Stark and Flensburger Schiffbau-Gesellschaft agreed to set up series production of the Vanta family in Flensburg. The bigger prize is the Future Combat Surface System. BAAINBw ran two operational experimentation campaigns in autumn 2025 from Eckernförde, demanding TRL 9 platforms able to make 300 nautical miles at 38 knots with a 30 mm gun; the first used the Tamsen Jet, a Combat Boat 90-type hull automated by Anschütz, which ran long legs autonomously but showed “limitations” in rough seas. Kurs Marine calls for at least 18 swarm-capable units, which makes Germany one of the more ambitious buyers in the emerging market for Drone Swarms in Europe: Countries, Companies and Programmes.

France has the widest catalogue and, so far, the fewest domestic orders. Naval Group’s 9.3-metre Seaquest S completed REPMUS 25 and Baltic Sentry, but as of February 2026 it had no sales and was offered for rental. Exail’s DriX is the quieter success: five H-8s for ISR went to an undisclosed European nation in June 2025, and January 2026 brought two H-9 orders, one for the hydrographic service SHOM and one from a navy innovation branch for counter-drone research. The Netherlands and Belgium, meanwhile, signed on 29 July 2026 for the design of 12-metre anti-submarine USVs carrying Thales’s Compact FLASH dipping sonar, to sail with the four Damen-built ASW frigates due from 2028; the design phase runs to early 2027.

The rest of the map is concepts and one-offs. The European Defence Fund is paying €65 million of the €95 million EUROGUARD project, a 45-metre, 500-tonne semi-autonomous vessel whose hull was presented at Baltic Workboats in Nasva, Estonia, on 21 May 2026 ahead of Estonian Navy trials by the end of 2027. Portugal’s €132 million Damen-built drone carrier D. João II is due in late 2026. Italy’s Intermarine began developing a modular MCM and seabed-surveillance USV for the Italian Navy in February 2026. Navantia UK’s 75-metre LASV75 and BAE Systems’ 100-metre “Type 91” are concepts without customers. Spain’s Indra tested its Nimbus combat cloud with USVs at REPMUS 2026, covered in our report on the Indra Nimbus naval trial at REPMUS 2026. In the Nordics, Saab’s Autonomous Ocean Core remains a test-bed capability on the Enforcer 3 boats rather than a fielded system.

Strike USVs: Ukraine’s proof and Europe’s response

Ukraine’s Independence Day parade on 24 August 2026 was the first made entirely of uncrewed systems, and the river section was the most revealing. Uforce’s Magura V7 carried the Sea Dragon air-defence fit, the Navy’s Sargan (also called Seawolf) appeared with rockets, a quadcopter hangar and an electronic-warfare suite, Security Service Sea Baby hulls passed with ramming charges, and a new, larger Magura MV11 was configured as a carrier for interceptor drones. As H I Sutton wrote for Naval News, these were “operational systems”, not prototypes. Kyiv began a regulated lift of its arms-export ban in October 2025 with naval drones among the first categories cleared. At NATO’s REPMUS 2025 exercise in Portugal, a Ukrainian red team won all five scenarios and simulated the destruction of a NATO frigate with Magura V7s.

Europe’s most concrete industrial answer runs through Ukraine rather than around it. On 20 November 2025 Kongsberg announced an investment in Poland to produce the Ukrainian Seawolf USV, developed by Nordex, alongside its remote weapon stations and counter-drone systems, at PLN 250 million in a first stage and potentially PLN 1 billion; the Seawolf-and-Protector pairing was on the stand at MSPO 2026 in Kielce. Norway is separately funding 200 maritime drones for Ukraine, worth NOK 1.2 billion (about $130 million), for delivery by the end of 2026 from Ukrainian and Norwegian producers. That is the closest thing Europe has to a strike-USV production line, and it belongs to a Ukrainian design.

The home-grown alternatives are demonstrators. Stark’s Vanta-12, conceived in October 2025 and launched by mid-2026, appeared at REPMUS 2026 with four MBDA Sea Venom anti-ship missiles and ten Cascade loitering munitions; our report on the Stark and MBDA Vanta-12 with Sea Venom covers the integration, but no navy has ordered it. Germany’s FCSS is still in experimentation, and Naval Group’s Seaquest S weapon modules are catalogue options. For scale, the US Navy on 29 September 2026 signed production agreements for 30 Medium Unmanned Surface Vessels at roughly $40 million each, ten apiece from Saronic, HII and Galliano, detailed in our analysis of the US Navy MUSV production awards; Europe’s comparable hulls are at prototype or concept level.

Türkiye’s USV industry in the European context

Türkiye matters here because it is one of very few NATO navies with a domestically built USV in commissioned service. Marlin, developed by Sefine Shipyard and ASELSAN, was the first Turkish USV to sail in a NATO exercise, Dynamic Messenger 2022 off Troia, and entered the Turkish Navy inventory as TCB 1101 on 19 January 2024. In August 2026 it laid Malaman training mines near Erdek in both autonomous and remote-controlled modes, which Janes noted puts Türkiye among the few operators able to lay mines from a USV. The armed ULAQ from ARES Shipyard and Meteksan received its flag at Istanbul Naval Shipyard in December 2025, and its sale to the Qatar Coast Guard, reported in January 2026, was Türkiye’s first armed USV export.

Ankara has also moved earlier than any European capital on expendable strike boats. In February 2026 the Defence Industry Executive Committee approved 100 one-way attack USVs: 40 ASELSAN and ARES Tufan boats, 32 STM and Yonca Yaktu craft and 32 from Havelsan and Sefine, to be employed in four-boat groups with line-of-sight and satellite links. During the Denizkurdu-I/2026 exercise on 20 to 25 September, with 100 ships at sea, an MKE one-way USV controlled from a Tuzla-class patrol boat destroyed a surface target with a live 100 kg warhead, and Admiral Ercüment Tatlıoğlu said the future operating concept will use crewed and uncrewed systems “in a way that supports one another”.

The European connection is thinner than the domestic record. No Turkish firm is inside the rMCM, MMCM or Dutch ASW programmes, and the export customers so far are in the Gulf and Asia-Pacific. The most tangible European deal is on the civil-security side: in April 2026 Havelsan agreed with VN Maritime and shipyard group Piloda to build unmanned and hybrid patrol craft near Naples for Italy’s Guardia di Finanza and coast guard, with a first order targeted for mid-2026 that has not been publicly confirmed. For European navies, Turkish USVs are a proven competitor in Gulf and Black Sea markets rather than a supplier of record.

Bottlenecks: rules, sea state, links and software

The first bottleneck is legal rather than technical. The IMO adopted its first Code for Maritime Autonomous Surface Ships on 21 May 2026 as a non-mandatory instrument, with a mandatory version targeted for 2028, but it is written for merchant ships; naval USVs still sail under national rules, exercise areas and waivers. That is why the UK’s L-USV Accelerator exists to prove that a vessel over 24 metres “can be legally certified, safely operated, and integrated” with a crewed warship, and why the German OPEX tenders asked for “safe participation in maritime traffic”. A Danish strait full of ferries is a different problem from a mine box off Zeebrugge.

The second bottleneck is the sea itself. The rMCM operators still keep a person on the Inspector 125 because automatic recovery of the AUV does not yet work in Sea State 4, Tamsen Jet met its limits in rough water, and most small ISR boats are rated to Sea State 4. Endurance and links are the other half of the equation: a 1,200-nautical-mile range, as claimed for Vanta-12, or 20 days at sea for a DriX H-9, is only useful with satellite communications that survive jamming. Data is a quieter constraint: the Belgian Navy’s first synthetic aperture sonar images were “pretty amazing”, in Commander Van Engeland’s words, and the volume of data has since become the problem.

That is where the industrial bottleneck starts. Integrating drones, mission software and a mothership’s combat system is slow, contract-by-contract work, which is why the Dutch ASW boat is being designed around its sonar from day one. Production capacity is the next gap: Stark’s Flensburg agreement, Kongsberg’s Polish line and Norway’s 200-boat order for Ukraine are the first attempts at European series output, and Maritime Robotics’ Eirik Hovstein put it bluntly in April 2026: “The US is in the lead. They are placing orders now to build up their arsenal.” The autonomy software is increasingly shared with land robotics, so progress in Europe’s Military UGV Programmes: Which Armies Are Buying feeds back into the maritime stacks, and much of the risk capital is flowing to Stark, Kraken, Uforce and the rest of the new tier of European Defence Tech Startups: Who Funds Them and Who Buys, while the primes hold the mothership and mission-system contracts. For the next two years the operational European USV will remain, above all, a minehunter.

Frequently asked questions

Which European navies operate unmanned surface vessels today?

The French Navy and Royal Navy operate Thales MMCM minehunting USVs, the Belgian and Dutch navies are integrating Exail Inspector 125 boats on their new rMCM motherships, and the Royal Navy has deployed Kraken K3 Scout ISR craft to the Gulf. Germany is trialling the Stark-built Seetaube, and Türkiye’s navy has commissioned Marlin and ULAQ. Most other European USV activity is still at trial or demonstrator level.

What is the difference between a mine countermeasures USV and a strike USV?

An MCM USV such as Inspector 125 or RNMB Ariadne is a reusable, 12-metre tug for sonars and mine-disposal vehicles, operated from a mothership outside the mine danger area. A strike USV such as Magura, Sea Baby or Türkiye’s Tufan is usually a small, fast, often expendable boat carrying a warhead or missiles. The first category is operational in Europe; the second is operational only in Ukraine and, in Türkiye, entering procurement.

Which companies build naval USVs in Europe?

Exail and Naval Group (rMCM, DriX, Seaquest), Thales (MMCM mission systems and sonars), Kraken Technology Group and Stark among the newer firms, Saab (Autonomous Ocean Core, Skeldar UAS, mine-disposal vehicles), Baltic Workboats (EUROGUARD), Intermarine, Navantia UK and BAE Systems with concepts, and in Türkiye ASELSAN, Sefine, ARES, Meteksan, STM and Havelsan. Kongsberg is financing production of Ukraine’s Seawolf in Poland.

Is Ukraine exporting its naval drones to Europe?

Not directly to European navies yet. Kyiv lifted its export ban in a regulated way in October 2025 and flagged naval drones as export-ready, and Uforce has been negotiating with Indo-Pacific buyers. The European route so far is industrial: Kongsberg is funding Seawolf production in Poland and Norway is paying for 200 USVs to be built for Ukraine by Ukrainian and Norwegian companies by the end of 2026.

Is Türkiye a partner or a competitor for European USV programmes?

A competitor, for now. Turkish USVs are in Turkish Navy service and exported to Qatar, but no Turkish company is inside the rMCM, MMCM or Dutch-Belgian ASW programmes. The nearest European link is Havelsan’s April 2026 agreement with Italian partners to build unmanned and hybrid patrol craft for Italian security agencies, whose first order had not been publicly confirmed as of September 2026.
