rMCM program

On 30 November 2021, Naval Group has laid the keel for the first of the twelve mine countermeasure vessels of the Belgian-Dutch rMCM program, intended for Belgium. The keel laying ceremony took place in Concarneau, in the presence of the Belgian Chief of Defence, Admiral Michel Hofman, and the Dutch Chief of Defence, General Onno Eichelsheim.

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

Kership, a joint venture between Naval Group and Piriou, is in charge of the production of the twelve vessels which are assembled in Concarneau. They will be armed afloat by Piriou. 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). ECA Group, as co-contractor, is in charge of the unmanned drones’ system. Thedrones will be produced in ECA Group workshop (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 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: «We are very happy to be here in Concarneau to take this next step in the program with the keel laying of the first mine countermeasure vessel. This program is the result of European cooperation between Belgium and the Netherlands, in which Naval Group is proud to participate. It is also the result of a solid industrial partnership and of a commitment to competitiveness between Naval Group and ECA Group. Our teams will continue their hard work to deliver these latest generation ships, specialised in mine warfare and perfectly adapted to the operational use targeted by the Belgian and Dutch navies».

Dominique Giannoni, CEO of ECA Group said: «ECA Group is pleased to be present at this ceremony alongside its partner Naval Group. All ECA Group teams are mobilised for the success of this highly innovative program: it aims at an unprecedented level of automation of mine warfare operations, with the coordinated implementation of underwater, surface and aerial drones. In close collaboration with Naval Group teams, we are developing an integrated and optimised system to meet the requirements of our Belgian and Dutch customers».

«In the context of mine warfare, the idea of increasing the distance between the threat and the crews is not new», announced Admiral Hofman, Belgian Chief of Defence. «In the 2015 NATO Maritime Operations study, the main shortcomings of shipborne systems were slow operation, poor mine discrimination, inability to detect buried and drifting mines, self-defence and the ability of platforms to easily project globally. It was already clear that the existing conventional platforms could not meet all these challenges. Therefore, we were looking for a reliable partner to carry out this small revolution in mine warfare».

CPF BAM Claude Bultot, head of the program said: «The Belgian and Royal Netherlands Navy can be proud of this innovative and (r)evolutionary mine countermeasures replacement program. The ambition of this program is to become the world reference in this field».

His Dutch counterpart, Captain (E) Sander van Luik, added: «This project is a fine example for making European defence more efficient. By drawing a common set of requirements as a starting point, Belgium and the Netherlands are able to quickly put to sea an innovative concept. Agreeing on the principals first, avoids haggling over every single design detail. This also allows us to be more flexible and adaptive. Thus, our binational team has been able to work more effective, relying on both nations’ combined expertise, working with Belgium Naval & Robotics towards a new capacity that can meet the operational challenges of the decades ahead».

These specialised mine warfare vessels are the first to have the capability to embark and launch or fly a combination of surface drones (themselves 12-metre/39.4-foot, 20-tonne vessels), underwater drones and aerial drones. The mine countermeasures vessels will use a fully robotic 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.

These mine countermeasure vessels have the following characteristics:

  • Length: 82.6 m/271 feet
  • Width: 17 m/55.77 feet
  • Displacement: 2800 t
  • Maximum speed: 15.3 knots/17.6 mph/28.3 km/h
  • Range: >3,500 nautical miles/4,028 miles/6,482 km
  • Crew: 63 people
  • Drone capabilities: ECA Group’s UMISOFT System, 2 unmanned surface vehicles (ECA Group’s Inspector 125), 3 autonomous underwater vehicles (A-18 equipped with ECA Group’s UMISAS 120 sonar), 2 towed sonars (T-18 equipped with ECA Group’s UMISAS 240 sonar), 2 Mine Identification & Destruction Systems (MIDS) systems (ECA Group’s Seascan et K-Ster C), 2 unmanned aerial vessels (UMS Skeldar’s V200), 1 ECA Group influence dredger integrating 5 CTM magnetic modules et 1 PATRIA acoustic module.
  • Embarkation capacity: 2 SOLAS rigid hull inflatable boats of 7 m/23 feet.
  • Handling: 2 side gantries with floating cradle for surface drones and commando boats, a 15t rear crane and a 3t overhead crane.

2nd Barracuda

At 7.14 a.m. on Friday, November 26, 2021, Naval Group CEO Pierre-Eric Pommellet began the transfer of the second Barracuda-class nuclear submarine – FS Duguay-Trouin (S636).

FS Duguay-Trouin (S636)
The transfer of the FS Duguay-Trouin (S636) submarine to the French fleet is scheduled for the end of next 2022

Mounted on twenty-four trolleys arranged in two parallel rows, the submarine, weighing approximately 4,500 tons, began to move at a speed of just under thirty meters per hour. Thus, the submarine Duguay-Trouin covered 120 meters separating the Laubeuf shipyard from the Cachin launching device. There was no big ceremony, as was the case in July 2019 with the transfer of the first submarine FS Suffren (S635) and the presence of the President of the Republic, Emmanuel Macron, this time. Nevertheless, many employees of the Naval Group and its subcontractors came to watch this ceremony of rolling out the submarine from the Laubeuf shipyard.

«The Duguay-Trouin rolled out less ceremoniously», agrees Jean-Luc France, director of the Naval Group in Cherbourg. «Nevertheless, this is an important event for the Naval Group team and its partners».

The first steel sheet of the Duguay-Trouin submarine was cut back in June 2009. In 2017, the Laubeuf shipyard began work on the integration of about 700 thousand pieces of equipment. The submarine hull was assembled by December 2020. «Together with TechnicAtome, we have just completed extensive testing of a nuclear facility», said Hervé Glandais, program director at Naval Group. The last phase of testing will continue at the Cachin facility.

The FS Duguay-Trouin (S636) attack-class nuclear-powered attack submarine is due to be delivered to the French Navy at the end of 2022.

The Barracuda class boat building program, Hervé Glandais noted, is the main one for the Naval Group. About 10,000 people and 800 enterprises are working on this program. In Cherbourg alone, 2,500 people work daily, including 800 partners and subcontractors.

In addition to FS Suffren (S635) and FS Duguay-Trouin (S636), the fleet will receive 4 Barracuda class nuclear submarines: FS De Grasse (S637), FS Tourville (S638), FS Rubis (S639) and FS Casabianca (S640). By 2026, the fleet will have four Barracuda-class submarines in service (one submarine every two years). The last boat in the series, Casabianca, will be delivered to the fleet in 2029.

Full digital radar

Thales Sea Fire, full digital radar is qualified by the DGA after exhaustive and thorough testing in Saint-Mandrier, the reference trial centre for the French naval forces. The radar is now handed over to Naval Group for integration into combat system on-board the FDI frigates.

Over a period of 18 months, the Sea Fire radar underwent a substantial number of land-based tests, mobilising a vast panel of resources and combined teams from the DGA, Thales and Naval Group. All testing took place at the Shore Integration Facility (SIF) on the DGA’s SESDA site in Saint-Mandrier in the South of France – a major testing reference centre in Europe for the naval sector. Since 1969, this facility has been testing and qualifying ashore every combat system and critical sensors of major ships (frigates and aircraft carriers) in service within the French Navy.

Evaluated and tested against an extensive range of situations including surface targets (light boats, surface vessels…), air targets (helicopters, jets, missiles, drones, etc.) in various environments. – the Sea Fire assured its ground-breaking ability to search simultaneously for air and surface targets in a difficult environment, scanning a range of several hundred kilometres with 90° in elevation and an unmatched refresh rate.

Thanks to the Sea Fire’s unique full digital technology (for instance digital beamforming), the radar delivers enhanced performance for all missions through dynamic radar resource management with very short response time. This digital radar is at the forefront of technological innovation and benefits from all Thales’s Big Data and cybersecurity expertise.

In addition, through its advanced radar software, the digital nature of the Sea Fire made possible the implementation of a high fidelity digital twin. Compared to classical simulations, the digital twin of the Sea Fire truly reproduces the radars’ behaviour and performance. It supports radar development throughout the product life cycle from initial development to in-service support, operation and upgrades. The use of a digital twin played a key role in securing the development schedule of the Sea Fire despite the Covid-19 crisis.

Assembled in Limours, south of Paris, with the contribution of a network of French small and medium- sized companies, Sea Fire production started in May 2018 and the first FDI shipset was delivered in May 2021 (4 panels).

Patrol Vessel 87

The third of the four Offshore Patrol Vessel 87 (OPV 87) ordered to Naval Group by Argentina has been launched at Concarneau shipyard (Brittany).

ARA Storni (P-53)
Naval Group launches A.R.A. Storni (P-53), the third Argentine Offshore Patrol Vessel

After the recent delivery of A.R.A. Piedrabuena (P-52), the third OPV A.R.A. Storni (P-53) was launched on Monday May 10th. The ship, which was partly built in Lanester by Kership Lorient and assembled in Concarneau by Piriou Shipyards, was launched yesterday.

This delivery is part of the contract signed by Naval Group with Argentina in 2018 to provide four multi-mission offshore patrol vessels. A.R.A. Bouchard (P-51) (ex-L’Adroit) had been delivered in December 2019, two months ahead of schedule, and A.R.A. Piedrabuena (P-52), the first of the three newly-built patrol vessels, was delivered on April 13, 2021.

The third vessel of the series will offer the same assets and characteristics as the A.R.A. Piedrabuena (P-52). Better armed than the A.R.A. Bouchard (P-51), more motorized, equipped with an active stabilization system and a bow thruster, it is also «Ice proven», i.e., adapted to navigation in the cold waters of Antarctica.

Jean-Claude Flandrin, Program Director, said: «The program continues to progress at a very steady pace, with the delivery on time of a vessel every six months, despite the global sanitary situation. The delivery of the A.R.A. Storni (P-53) should take place in October this year, in line with the contract schedule».

«We are proud of the trust that the Argentine Navy has placed in Naval Group for the supply of these latest-generation multipurpose vessels that will enable the country to carry out its sovereign missions. Their timely delivery despite the sanitary context demonstrates the Group’s commitment to its Client», added Olivier Michel, Sales Director for Latin America.

 

OPV 87, an innovative vessel

The Argentinean Offshore Patrol Vessels benefit from innovations developed by Naval Group and sea proven by the French Navy, which has operated L’Adroit in several oceans for six years for multiple maritime security operations, either alone or in cooperation with other Navies:

  • Very high endurance and excellent sea-worthiness;
  • A 360° visibility from the bridge and a unique mast for a panoramic radar coverage;
  • The discrete and safe implementation in less than five minutes of fast crafts for Special Forces thanks to an ingenious ramp system at the bow of the patroller.

This range of ships also benefits from Naval Group’s expertise in information and command systems, allowing for extensive surveillance of the maritime space and the detection of suspicious behaviours. The A.R.A. Storni (P-53) is equipped with the Polaris system and NiDL tactical data link system, specifically developed by Naval Group for state missions at sea and sea-proven by the French Navy.

 

Technical features

The Offshore Patrol Vessel is able to stay on deep seas during more than three weeks, to reach a speed of 20 knots/23 mph/37 km/h and to accommodate a helicopter. Implemented by a reduced crew of 40 members, it is also able to accommodate about twenty extra passengers.

FREMM DA Alsace (D656) is the first frigate with enhanced air defence capability. Her role will be the anti-aircraft defence of major units such as the Charles de Gaulle aircraft carrier, or that of PHA-type landing helicopter docks, within the framework of a naval air and amphibious group.

Despite the health crisis, the FREMM DA Alsace (D656) is being delivered on schedule by shifts from Naval Group and its industrial partners. Benefiting from the experience acquired on the FREMM already delivered, it also incorporates several capability upgrades in response to rapidly changing technologies (communications, cyber defense, etc.).

The main milestones of FREMM DA Alsace (D656):

  • February 2018: Key laying of the first block;
  • April 2019: Floating out of construction dock;
  • October 2020: First sea trial;
  • 16 April 2021: Delivery in Toulon.

 

An industrial success that mobilises the skills of the entire naval industry

The FREMM program mobilises many skills and hundreds different trades including architects, boilermakers, welders, mechanics, systems engineers, etc.

Like the other units of the FREMM series, Alsace (D656) represents around three million working hours from conception to delivery, half of these working hours are provided by Naval Group sites. In addition to Lorient where the frigate is designed and assembled, Toulon-Ollioules and Paris-Bagneux are also involved for the combat system, Nantes-Indret for the propulsion, Angoulême-Ruelle for the equipment, and Saint-Tropez for the underwater weapons.

The other half of the work hours is accounted for by Naval Group’s partners and subcontractors. Indeed, the FREMM program benefits from the best equipment on the market and calls on a large number of companies, including Thales, MBDA, Sagem, Jeumont, MTU, Oto Melara and Avio.

Alsace (D656) will be based in Toulon, where the teams of the Services Department will deploy all their industrial resources and skills to ensure the operational availability of this ship.

«We are very pleased to be here in Toulon for the delivery, on schedule despite the health crisis, of this first FREMM multimissions frigate with enhanced air defense capability. I would like to express Naval Group’s gratitude to our clients, who have placed their trust in us and are working with us on a daily basis to build these versatile frigates. Alsace (D656) has the same exceptional anti-submarine capabilities as the previous units of the FREMM series but with this new version, the French Navy will benefit from strengthened air defense capabilities, in accordance with the commitments of the military programming law», Pierre Eric Pommellet, chairman and CEO.

Stimulus plan

The French Minister of Armed Forces, Florence Parly, has announced that the Armament General Directorate (DGA) has signed an order to purchase eight additional H225Ms and a second VSR700 prototype. The H225Ms will be operated by the French Air and Space Force. The VSR700 is an unmanned aerial system being developed for the French Navy in partnership with Naval Group. This order is part of a Stimulus plan to support the national aeronautical industry announced by the French government in 2020. For Airbus Helicopters, the plan also includes an order for two H145s for the Sécurité Civile and 10 H160s for the French Gendarmerie Nationale.

France orders H225Ms and VSR700 prototype in support of helicopter industry

«We are very thankful to the French government for their support of the aeronautical industry through the Stimulus plan. This is a win-win situation as the aircraft fulfill a real operational need for the French armed forces and this order allows Airbus Helicopters to secure jobs and key skills in the medium term», said Bruno Even, Airbus Helicopters CEO. «The French armed forces are facing increasing and varied challenges and I am confident that the H225M, thanks to its excellent range and multirole capacity, will be an efficient and reliable asset that will enhance their operations at home and abroad. The VSR700 is also a crucial programme. It will provide the French Navy with a highly capable autonomous platform and it will pave the way for future unmanned systems within the Airbus Helicopters portfolio».

Like the rest of the aeronautical industry, the helicopter industry has been impacted by the Covid-19 pandemic. 2020 saw the worldwide market decrease by 50%. The support of the French government will help secure 960 jobs during the next three years for Airbus Helicopters and its suppliers.

These contracts will benefit the French helicopter industry as a whole, including other key French aerospace providers such as Safran Helicopters Engines with the H225M’s Makila 2A engines, Safran Power Units with the Saphir 20 auxiliary power unit, Safran Electronic Defense with the electro-optical system Euroflir 410M NG and the Sigma inertial navigation system, and Thales with the VUHF radio TRA6034 and IFF transponder TSC4000. But with more than 300 French Tier 1 suppliers involved in the H225M’s supply chain, the contract will also benefit a variety of small and medium enterprises. The VSR700 is based on the Cabri G2 light helicopter built by local SME Hélicoptères Guimbal.

First deliveries of the H225Ms are planned to start in 2024 and will fulfill the Air and Space Force’s operational needs and the long awaited replacement of the Puma fleet.

Thanks to a modular and versatile configuration allowing the integration of diverse equipment, the aircraft will be dedicated to a wide range of military missions including combat/search and rescue, medical evacuation, support to the population in times of crisis, and tactical training. While based in the Air and Space Force’s Cazaux base in Southwest France, the helicopters will be deployed across the country and will also support the French armed forces’ operations overseas.

With more than 104 helicopters in service and more than 143,000 flight hours accumulated to date, the H225M is a recognized combat-proven, versatile and reliable workhorse for military missions worldwide. Among the essential operational advantages offered by the 11-tonne helicopter is the in-flight refueling capacity, already tested by the French and Brazilian air forces.

Designed to operate alongside other shipborne naval assets, the VSR700 unmanned aerial system (UAS) is being developed within the frame of the SDAM (Système de drone aérien de la Marine) programme for the French Navy. The VSR700, derived from Hélicoptères Guimbal’s Cabri G2, is an unmanned aerial system in the 500-1000 kg maximum take-off weight range. It offers the best balance of payload capability, endurance and operational cost. It is capable of carrying multiple full-size naval sensors for extended periods and can operate from existing ships, alongside a helicopter, with a low logistical footprint.

The first prototype of the VSR700 performed its maiden flight in 2020 and has recently begun expanding its flight envelope.

FDI frigates

On March 29, 2021, during a visit to Lorient of the French Minister of the Armed Forces, Florence Parly, Naval Group received notification of the order for two Frégate de Défense et d’Intervention (FDI) frigates by the French Defense Procurement Agency (DGA). The acceleration of the FDI program will support the activity of the Naval Group site in Lorient where the frigates are designed and built, also ensuring the preservation of skills.

The two frigates – the second (Admiral Louzeau) and third (Admiral Castex) in a series of five – will both be delivered in 2025, whereas the original plan was to deliver them every 18 months.

The first FDI (Admiral Ronarc’h), for which construction work began in 2020, is scheduled for delivery in 2024.

Pierre Eric Pommellet, Chairman and CEO of Naval Group said: «We are honoured by the confidence of the Ministry of the Armed Forces. It is a strong message for local jobs and the preservation of our very unique skills, but also to international navies that could be interested in this frigate. We will mobilise all our industrial and technological excellence to meet the new deadlines».

With a tonnage of more than 4,200 tonnes and a length of 121 metres/397 feet, the FDI frigates are based on a digital and scalable architecture built around our SETIS 3.0 combat management system.

They can conduct all the missions of modern navies (anti-air, anti-surface, anti-submarine warfare or special forces projection) and address new threats such as cyber attacks and asymmetric threats.

The FDI also benefits from the best technologies available on the naval defence market, including the latest Thales multi-function radar with active antenna and fixed panels as well as a fully digital electronic warfare system.

Naval Group employs 2,200 people at its Lorient site, where it builds surface ships for its customers, including the FREMM multimission frigates and Gowind corvettes.

Third generation of SSBN

Florence Parly, French Minister of the Armed forces, will announce on February 19, 2021, at the Centre of expertise for Hydrodynamic techniques of the French Defence Procurement Agency (DGA), the launch of the program for the third generation of SSBN (SNLE 3G) for the French Navy. This submarine program is a major challenge for Naval Group, a leading industry partner in the service of the French sovereignty. The first of class is scheduled to enter operational service by 2035. Three other submarines will then be delivered, every five years.

SNLE 3G
Launch of the third generation of French nuclear-powered ballistic missile submarines (SSBN)

Pierre-Eric Pommellet, Naval Group CEO, declared on this occasion: «Naval Group is very proud to put its skills, talents and industrial resources at the service of France’s nuclear deterrence. The whole company will be mobilized with its partners to carry out this exceptional project. We are aware of our responsibility and we will do our utmost, as previous generations have done, to provide France with the tool of its sovereignty».

SSBN remain one of the most complex industrial products ever made. Their design and construction require rare know-how, unique industrial means and the ability to federate the contributions of two hundred partner companies that make up the French defence industrial base, present across the country.

Naval Group benefits from a unique position as a systems architect and integrator which enables it, in collaboration with TechnicAtome, the prime contractor for the nuclear boiler room, to commit to the overall performance of these armed vessels, to assume overall responsibility for their construction and to guarantee control of quality, deadlines and costs.

 

A core program for French sovereignty

The program aims to provide a new generation of four nuclear-powered ballistic missile submarines that will serve the French Navy’s operational needs between the 2030s and the 2090s.

They will gradually replace the second-generation SSBN that will be phased out of active service during 2030s and 2040s, to be replaced by these third-generation submarines.

The SNLE 3G program is being carried out on behalf of the French government, under the auspices of the DGA and the French Alternative Energies and Atomic Energy Commission (CEA), in conjunction with the Armed Forces Staff and the French Navy.

Naval Group remains the key industry partner of French nuclear deterrence

 

Mobilisation of the whole the naval defence industry

More than 200 companies from the French defence industrial and technological base will work with Naval Group to provide design or construction services for equipment and systems.

In the end, over the next 30 years, this program will represent up to 100 million hours of work, including 15 million hours of design and more than 80 million hours of construction.

 

400 skills required

Most of Naval Group’s sites will be mobilised for this program.

At the Cherbourg site, more than 300 employees work in design activities, and construction represent more than 2,000 employees. The teams in Cherbourg will build the platform (hull, structure, part of the internal modules), integrate the equipment and systems into the platform, and carry out the commissioning and testing of the submarine’s facilities.

The Nantes-Indret site will produce the main components of the boiler room and build the major modules, such as the engine unit module and the nuclear boiler room module.

The Angoulême-Ruelle site will design and build the submarine’s structural equipment: weapon launcher tubes, masts, weapon handling system, etc.

The Ollioules site will be the reference site for embedded information systems. It will design and integrate the combat system and the control system.

The Bagneux site concentrates various program management activities.

The Lorient site will contribute to the design of the SNLE 3G, and will produce the composite parts.

The Brest site will be called upon to prepare the reception and support of the future SNLE 3G, at the heart of the Ile Longue base, as well as its tests on the launching device in Cherbourg.

3D-Printed Propeller

Naval Group manufactured this new-generation propeller thanks to a metal 3D printing process. Mounted on a tripartite minehunter, the propeller will now accompany the ship in all of its operational missions.

Naval Group equips a French navy ship with a 3D-printed propeller

This propeller is a technological exploit. With its 2.5-metre/8.2-foot span supported by five 200-kg/441-lbs. blades, the equipment left the workshops of the Naval Group site of Nantes-Indret in October 2020 for the site of Brest in order to be mounted on the propeller shaft. As part of its major technical stop, the assembly was transferred to the submarine base to be mounted on the intermediate shaft of the Andromède in November. Sea trials were then performed successfully at the end of December.

 

A world first for this on-board innovation

«Obtaining military naval quality requires rigorous development. Nearly three years of R&D – carried out by the Technical and Innovation Department in cooperation with the Ecole Centrale de Nantes within the framework of the LabCom Joint Laboratory of Maritime Technology – went into the development of the deposition process of metal wire fusion», states Emmanuel Chol, Director of the Nantes-Indret site. «Today, we witness a world first. It is the largest metal 3D-printed thruster ever to have been manufactured and the first propeller resulting from this technology, embarked on board a military ship and manufactured for use beyond just sea trials».

The harsh conditions in which ships are used warrant the need to meet strict requirements (corrosion, fatigue, shock resistance, etc.). Naval Group worked together Bureau Véritas throughout the process to present its technical justification file in order to allow the SSF (Fleet Support Services) and the DGA (French Defence Procurement Agency) to authorise the trial of the blades produced on a military ship in normal operating conditions. The blades received certification from Bureau Véritas.

 

€7 million investment in metal 3D printing in 2021

For Eric Balufin, Director of the Naval Group site of Brest, «the assembly of this 3D-printed propeller shows great promise for the future. This new technology will enable us to considerably reduce technical constraints, and therefore allow for new manufacturing solutions for complex geometrical shapes which cannot be produced through conventional processes. It will also enable us to greatly reduce production time and consequently in-service support».

This propeller is a first step. A new development phase will begin, aimed at revamping the detailed design of other parts so that they benefit from 3D printing (acoustic discretion, weight reduction, increased productivity of the parts).
