On 29 March 2023, the first of the twelve mine countermeasure vessels of the Belgian-Dutch rMCM programme, the M940 Oostende intended for the Belgian Navy, was floated out in Concarneau. The launching ceremony took place in the presence of Ludivine Dedonder, Belgian Minister of Defence, Kajsa Ollongren, Dutch Minister of Defence, and Patricia Mirallès, French Secretary of State for Veterans and Memory. During this day, Naval Group also laid the keel for the third of the twelve vessels, the M941 Tournai, intended for the Belgian Navy.

This programme was awarded in 2019 to Belgium Naval & Robotics, the consortium formed by Naval Group and Exail1 , following an international competition. It provides for the supply to the Belgian Navy and the Royal Netherlands Navy of twelve mine countermeasures vessels and around a hundred drones integrated inside a toolbox that will equip the vessels.

The first delivery is scheduled for the end of 2024 in Zeebrugge, Belgium. Deliveries will then be
staggered until 2030.

Pierre Eric Pommellet, CEO of Naval Group said: “I am very pleased to be present here in Concarneau at our Piriou partner shipyard, alongside Exail, to celebrate the progress of this unique programme which is the story of a shared vision for the future of mine warfare and European naval defence. We are working together to develop this game-changing defence solution that will serve Belgian and Dutch sovereignty and prepare the future of mine countermeasures in the naval domain.”

Ludivine Dedonder, Belgian Minister of defence stated: “In a world in full swing due to geopolitical upheavals, our cooperation is all the more strategic. The operational concept developed by the Belgian and Dutch navies is a world first and revolutionary in several ways. This project, whose first ship is launching today, shows that cooperation, solidarity and innovation are key values for our common security. With this renewal programme for our mine countermeasure capabilities, we can be proud of our contribution to defence innovation, to face the security challenges of our time together.

A unique industrial and European partnership

Naval Group, as overall architect and prime contractor, is responsible for the design of the ships, the overall integration, and the testing and commissioning of the mission system (combat system and mine countermeasures system). Kership, a joint venture between Naval Group and Piriou, is in charge of the production of the twelve vessels which are assembled in Concarneau and Lanester. Exail Robotics, as co-contractor, is in charge of the unmanned drones’ system. Most of these drones will be produced in Exailfactory (Ostend, Belgium). The maintenance of the ships will be carried out in Belgium in close collaboration between the Belgian Navy and Naval Group Belgium, with the assistance of its partner Flanders Ship Repair.

The rMCM programme is also a major element of European Defence. This programme demonstrates that European countries can work together to define their needs and share a solution that is destined to become a reference in the mine countermeasures field, not only for the Belgian and Dutch navies, but also for other navies in Europe and around the world.

The solution acquired by the Belgian and Dutch navies is a complete paradigm shift in the way mines are fought by adopting a remote position (stand-off) which reduces the risk for personnel and the mothership and allows a substantial increase in the speed of coverage of mined areas.

A resilient vessel and a latest generation toolbox

These specialised and cyber secured by design mine countermeasures (MCM) vessels are the first to have the capability to embark and launch a combination of surface drones (themselves 12-metre, 18- tonne vessels), underwater drones and aerial drones. The mine countermeasures vessels will use a mainly autonomous system for detection, classification and neutralisation of mines. They can withstand underwater explosions and have very low acoustic, electrical and magnetic signatures, in line with the missions to be carried out.
