M940 Oostende: Belgium’s leap into the future of naval mine warfare

From minehunting to remote operations

The Oostende is the lead ship of twelve new MCM vessels (six for Belgium and six for the Netherlands) being built under the rMCM – remote mine countermeasures program. The contract, worth approximately €1.8 billion, is being executed by Belgium Naval & Robotics, a consortium formed by Naval Group and Exail (formerly ECA Group).

Unlike traditional minehunters, Oostende is not designed to sail into minefields. Instead, she serves as a command-and-control mothership, deploying and coordinating an array of uncrewed systems — surface, subsurface and aerial — that perform the dangerous tasks of detection, classification and neutralization at a safe distance.

- The arrival of Oostende marks the first step in our transition toward a new generation of mine warfare — safer, more efficient and better suited to the maritime challenges of tomorrow, said Vice Admiral Tanguy Botman, Commander of the Belgian Navy.

High technology at sea

Measuring 82.6 meters in length with a full-load displacement of around 2,800 tons, Oostende is a striking blend of traditional naval design and advanced digital infrastructure.

Her onboard “toolbox” includes a full suite of unmanned systems:

• Inspector 125 USVs (uncrewed surface vessels) for mission deployment,
• A18-M autonomous underwater vehicles (AUVs) for mine detection,
• and Seascan and K-STER remotely operated vehicles (ROVs) for identification and neutralization.

All systems are linked through an integrated command-and-control architecture, enabling Oostende to coordinate complex MCM operations over long distances while minimizing human risk.

In practice, the ship acts as a floating operations center — a node in a broader network of autonomous platforms.

Carrying a legacy forward

For decades, Belgium’s Tripartite-class minehunters — developed jointly with France and the Netherlands — represented NATO’s benchmark for mine warfare excellence.

The Oostende inherits that legacy, combining Belgian expertise, NATO know-how and European innovation.

As the Belgian navy phrased it:

- Oostende is not built to hunt mines herself. She is a mothership — a platform from which drones and autonomous vehicles operate. Mine warfare of the future happens remotely — faster, safer and more precise.

Versatility beyond mine warfare

Although designed primarily for mine countermeasures, Oostende was conceived with multirole flexibility in mind.
The vessel can also undertake:

• patrol and surveillance operations,
• protection of critical underwater infrastructure such as cables, pipelines and offshore wind farms,
• search-and-rescue and maritime reconnaissance missions.

Her modular architecture allows for future upgrades, integrating new generations of drones, AI-assisted sonar analysis and advanced data-fusion systems.

A European model of cooperation

The rMCM program goes far beyond shipbuilding: it embodies a new model of European naval cooperation.

Construction of hulls takes place in Lorient and Concarneau (France), while integration and fitting-out are carried out in Belgium.

The project involves dozens of European companies and research institutes, reinforcing Europe’s strategic autonomy in unmanned maritime technologies.

- This is not just a new ship — it’s a new way of operating, reads an official navy statement. - With Oostende, Belgium takes a decisive step into an era where human skill and technology work hand in hand to secure our seas.

Symbolism and future outlook

The ship’s name carries deep meaning. The city of Ostend (Oostende) hosts both Belgium’s Naval Academy and the NATO Centre of Excellence for Mine Warfare.

Her arrival there is thus more than ceremonial — it symbolizes the meeting of tradition and innovation, a bridge between Belgium’s proud naval heritage and the digital age of autonomous maritime operations.

In a time when undersea infrastructure security and hybrid maritime threats are growing in importance, Oostende represents a strategic leap forward.

By merging human expertise with robotic precision, Belgium once again positions itself at the forefront of NATO mine-warfare innovation — showing how European cooperation can shape the oceans of tomorrow.
