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). For example, 3D-printed production of thrusters will provide ships with greater efficacy at sea: increased thrust efficiency, stealth and lightening.

Pierre Eric Pommellet, Chairman and CEO of Naval Group said: «We are delighted with the announcement by the President of the French Republic, which will enable France to maintain its position in the very restricted circle of major powers holding a nuclear aircraft carrier. This project will help develop jobs in the defence industrial and technological base and ensure the continuity of our skills in the current health and economic crisis. Naval Group, its partners and its entire ecosystem will enable the French Navy to benefit from the best naval systems for its flagship. We are committed, as an overall architect, to respond, together with our partners Chantiers de l’Atlantique and TechnicAtome, as well as Dassault Aviation, to the expression of needs of the French general armament directorate (DGA) and the French Alternative Energies and Atomic Energy Commission (CEA). Finally, this project will make it possible to develop innovation in the fields of propulsion and high added-value military systems, thus maintaining France’s technological lead and its position as a key geostrategic player. This is a huge pride for Naval Group to begin the building of the biggest warship France has ever built».

 

Naval Group has been contributing for 60 years to the design, construction and maintenance in operational condition of the French aircraft carriers

As the European leader in naval defence, Naval Group has for many decades ensured the technological superiority of the vessels of the French Navy and its international customers. Their operational excellence has been regularly demonstrated.

Among its many accomplishments, Naval Group has contributed to the design, construction and maintenance in operational condition of the three aircraft carriers of the French Navy: the Clémenceau, the Foch and the Charles de Gaulle. These ships have contributed to France’s influence in many conflict areas around the world. Naval Group is one of a very small number of industrial companies capable of building aircraft carriers.

More specifically, Naval Group has also built and integrated, in partnership with the CEA and TechnicAtome, the two nuclear boilers on-board the Charles de Gaulle aircraft carrier, the first French aircraft carrier equipped with nuclear propulsion. This nuclear-powered vessel has proven her reliability and safety. Nuclear propulsion gives this ship a considerable autonomy at sea and a great flexibility of use.

Having entered active service in 2001, the aircraft carrier Charles de Gaulle will be in service until approximately 2038.

 

Naval Group’s exceptional skills, unique in Europe, will be fully mobilised

Naval Group, as a system integrator and prime contractor for the French Navy’s submarines and surface vessels, has developed advanced and rare skills. Among its expertise, Naval Group has skills in three key areas in particular: the activities of architect and overall prime contractor, of systems integrator of complex naval weapon systems, and concerning nuclear propulsion, the manufacture and assembly of reactors, and the maintenance in operational condition of nuclear boilers.

Naval Group also has unique expertise in Europe in the integration and implementation of an aircraft carrier equipped with catapults and landing brakes as well as her air group. Integrating more than 200,000 pieces of equipment in 2,500 premises, producing more than 10,000 drawings, managing more than 3,000 contracts, and assembling 1,200 km of cables and 300 km of piping require a cutting-edge expertise. This expertise also covers the integration of the combat and navigation systems. Fully interconnected with allies units, the combat system enables to prepare, coordinate and lead the aircraft carrier’s actions and those of the naval aviation group in real time. The combat system also ensures the ship self-defence and the security of internal as well as external communications.

In addition, Naval Group masters the implementation of fighter aviation on aircraft carriers with catapults and arresting strands. The aircraft is the central element of the aircraft carrier, whose main function is that of a mobile air base capable of operating on all the seas of the globe.

In addition, Naval Group has infrastructures dedicated to these areas of expertise. For nuclear propulsion, for example, there is a test platform for turbo-alternator modules at the Naval Group site in Nantes-Indret. The company also has integration platforms for combat systems and control systems, and a unique tool for simulating flows on the flight deck of aeronautical munitions combined with virtual reality visualization.

 

The project for the future aircraft carrier guarantees the durability of skills and jobs for the entire French defence industrial and technological base

The development and construction of the new generation aircraft carrier represents an investment of nearly twenty years, from 2021 to 2038. After a sketch phase, Naval Group and its industrial partners will now be in charge of carrying out a two-year preliminary design studiy, which will be followed by detailed design studies that will finally precede the development and construction of the aircraft carrier, a product of rare complexity.

The nuclear component of the propulsion, the implementation of on-board aviation and the operation of the new-generation aircraft carrier will lead Naval Group to reinforce key skills of engineers, technicians and workers at all Naval Group sites: Lorient, Nantes-Indret, Toulon, Angoulême-Ruelle and Brest, as well as those of its major partners Chantiers de l’Atlantique, TechnicAtome and Dassault Aviation.

FREMM Lorraine

Naval Group has launched the FREMM Lorraine (D657) in Lorient on Friday 13th November. This ship was ordered by the French General Directorate of Armament (DGA) on behalf of the French Navy. The program management is entrusted to the Organization for Joint Armament Cooperation (OCCAR). The FREMM Lorraine (D657) is the tenth unit of the FREMM series produced by Naval Group, and the eighth and last one added to the French Navy’s fleet.

The French Minister of Armed Forces (Minister of Defence) Florence Parly, Admiral Pierre Vandier, Chief of Staff of the French Navy, and General Engineer Emmanuelle Thivillier, in charge of naval programs at the French General Directorate of Armament (DGA) as well as the Chairman and CEO of Naval Group, Pierre Eric Pommellet, alongside employees from the Lorient site participated to the launching ceremony.

 

The launch of the eighth French Navy’s FREMM

Fifty-four months after the start of the production, the FREMM DA Lorraine (D657) left the construction form of Naval Group site in Lorient. This operation took place on Friday 13th November 2020, fully complying with the schedule set by the Military Planning Law, while respecting the safety and health rules currently enforced.

Technical adaptations have been made on both FREMM DA such as a more powerful multifunction radar supplied by Thales, enhanced communications, three additional consoles of the Setis Combat Management System in the «central operations center» with an enhanced air defence capability through the use of Aster 15 and Aster 30 missiles. The FREMM DA also benefits from a new mast, optimized to increase detection performance. In addition to performing the same anti-submarine warfare missions as the previous FREMMs, the FREMM DAs will be responsible for the air defence of major units: Charles de Gaulle aircraft carrier, or amphibious helicopter carriers (PHA) as part of the naval or amphibious air group.

More generally, the FREMM frigates integrate the evolution of systems over time to ensure the latest units of the series benefit from the latest technologies such as: additional cyber capabilities, deployment of Liaison 22 (liaison between NATO military units), integration of a tactical digital table, etc.

 

Meeting the operational requirements of the French Armament Procurement Agency (DGA)

«Throughout this demanding program, we have maintained close ties with our customer, in order to best respond to the expectations and the technological challenges regarding the onboard innovations. This feedback led us to change our industrial organization. Modular construction, supply chain optimization and block pre-fabrication have reduced construction lead times and, ultimately, production costs. As a result, we have gained in efficiency and performance, while at the same time improving the working conditions of our employees, which has led to a considerable reduction in accidents at work. We are proud to launch today the latest French FREMM»! declared Laurent Espinasse, Executive Vice-President for Industry at Naval Group.

Naval Group’s site in Lorient offers industrial infrastructures that enable us to meet the technical and technological challenges of the latest generations of military ships, including a 15,000 m2 covered construction form.

The design tools and methods have evolved considerably during the FREMM program thanks to virtual reality. All of the ship’s data, including equipment operating data, is integrated into a digital mock-up. The infrastructures have also been modernized, including the extension and renovation of the construction nave, the installation of three covered paint booths and the extension of the quay.

 

Ensuring the preservation of key competencies

To deliver frigates with the required military performance, Naval Group has mobilized no less than 250 skills throughout the program. Some of them are very specific and rare and are often the result of a long or even very long acquisition: sheet metal carpenter, formator-straightener, hull welder, pipe fitter…

Naval Group promotes the recruitment of young talents and has recruited 400 work-study students since the beginning of the year and even during the sanitary crisis. This is 50 more than in 2019 and Naval Group site in Lorient is home to 58 of them.

Naval Group is also implementing specific training programs to develop these rare and unique skills, through the introduction of the certificate of joint qualification of metallurgy (CQPM). This certification training, takes place alternatively in a training organization and in industrial workshops over twelve months. A CQPM carpenter-sheet metal worker was opened in September 2019, in collaboration with the IUMM of Lorient, at a Naval Group site in Lorient.

 

Technical characteristics of FREMM DA

The FREMM program has been running on a stable schedule since the last Military Planning Law. Eight units of the FREMM series have been delivered between 2012 and 2019. Aquitaine (D650) in 2012, Provence (D652) in 2015, Languedoc (D653) in 2016, Auvergne (D654) in April 2017, Bretagne (D655) in July 2018 and Normandie (D651) in July 2019.

After recent commissioning of INS Khanderi (S22) in September 2019 and the launch of the INS Vela (S24) in May 2019, the INS Vagir (S25), the fifth of the series of six Kalvari-class submarines ordered by India in 2005, to be launched.

This event highlights the success of the indigenous submarines construction program of the Government of India. These submarines have been completely built by Mazagon Dock Shipbuilders Limited (MDL) through a transfer of technology from Naval Group, in line with Indian Government’s «Make in India» policy. This series of six submarines are fitted with a number of equipment, built in India by qualified and highly trained industrial Micro, Small and Medium enterprises (MSMEs) which form the sound base of the Indian submarine building ecosystem.

«Naval Group is proud to be part of first of its kind P75 Kalvari program to deliver entirely «Made in India» submarines to the Indian Navy. The P75 program is a major element of the strategic Indo-French partnership developed over the last decades. This launch, amidst Covid-19 challenges, represents a new milestone for this unique industrial program and illustrates the Aatmanirbharta (self-reliance) of Indian Navy and industry», mentioned Alain Guillou, Senior EVP – International Development at Naval Group.

The Scorpene is a conventional-propulsion submarine designed and developed by Naval Group for all types of mission, such as surface warfare, anti-submarine warfare, long-range strikes, special operations or intelligence gathering. Extremely stealthy and fast, its level of operating automation allows for a limited crew which reduces its operating costs significantly. Its combat edge is highlighted by the fact that it has 6 weapon launching tubes and 18 weapons (torpedoes, missiles, mines).

With 14 submarines sold internationally by Naval Group, the Scorpene is an essential reference product in the area of conventional attack submarines (SSK) for Navies across the world. The Scorpene can be adapted to meet special needs of international navies.

Naval Group is present in India through its 100% subsidiary Naval Group India. Established in September 2008, Naval Group India’s mission has been to support the indigenisation of equipment for Scorpene submarine, to develop the Indian defence eco-system, as well as to develop design services in India with talented Indian engineers.

Naval Group India endeavours to be a visionary and to further its involvement in empowering more industries by creating a robust eco-system that can cater to the varied defence needs of the country.

French Barracuda

Naval Group delivered on 06 November 2020 the Suffren (S635) nuclear attack submarine (SSN) to the French Armament Procurement Agency (Direction Générale de l’Armement) at the Toulon naval base. Intended for the French Navy, the Suffren is the first in a series of six SSN that will gradually replace the submarines of the Rubis-class. The delivery of the Suffren took place today in the presence of a small number of high-ranking personalities, due to the health crisis. Florence Parly, French Minister of Defence, General François Lecointre, Chief of Staff of the French Armed Forces, Joël Barre, Delegate General for Armament, Admiral Pierre Vandier, Chief of Staff of the French Navy, Victor Salvetti, Director of military applications at the French Alternative Energies and Atomic Energy Commission (CEA), Pierre Eric Pommellet, CEO Naval Group, and Loïc Rocard, CEO TechnicAtome, all welcomed this major milestone of the Barracuda program, in the presence of several representatives of the political, industrial and military worlds, including crew members.

Suffren (Q284)
Naval Group delivers the Suffren (S635) to the French Defence Procurement Agency (DGA)

Launched in 1998 by the French Defence Procurement Agency (DGA), the Barracuda program renews the submarine component of the French nuclear deterrence capability consisting of six Rubis-class submarines that entered service in the early 1980s. The associated development contract was notified at the end of 2006. More than ten years of studies were required to define a submarine that meets the French Navy’s operational requirements. This first delivery is the beginning of a phase leading to the qualification of this new class.

The delivery of the six submarines will take place over a decade. With a lifespan of more than 30 years, the Suffren-class submarines will be the backbone of the French submarine forces until at least 2060, making it one of the major weapon systems of this century.

Pierre Eric Pommellet, CEO Naval Group, declared: «What a long way Naval Group has come with its industrial and governmental partners since the first metal sheet was cut on December 10, 2007, less than a year after the DGA had signed the acquisition contract. The industrial challenges have been numerous. I salute the commitment of Naval Group’s design and production teams, of TechnicAtome – the prime contractor for the onboard nuclear boiler room – as well as those of the DGA, the CEA and the French Navy. Hundreds of French companies – both large and small, at the forefront of which Naval Group stands, have been and continue to be mobilised for the construction of this program. This initial success can only strengthen our collective commitment to deliver the next unit of the Barracuda series, the Duguay-Trouin, in 2022, followed by the other four submarines by the end of the decade».

The construction of these Barracuda submarines mobilises a wide range of exceptional know-how in the most advanced technologies.

Among these, the very special steels, underwater acoustics performances, and the weapon systems make the SSN Barracuda one of the most efficient submarines in the world.

The Barracuda submarines, with their navigation and communication means and their centralised and automated control are also more manoeuvrable and mobile. Another major innovation is the optronic mast, which replaces the telescopic mast, ensuring better collection of visual information and better sharing of this information among the crew. This new feature, combined with advanced detection capabilities, guarantees the superiority of Barracuda submarines in their intelligence missions.

The Barracuda series also offers the French Navy a real combat superiority with, for the first time, a deep strike capability thanks to MBDA Naval Cruise Missiles (NCM). They can also use the Naval Group new Naval Group heavy torpedo F21 as well as MBDA SM39 missiles. The Barracuda submarines also enable the discreet and enhanced deployment of special forces.

This technological and capability leap is the result of more than twenty years of collective work between Naval Group and hundreds of partners of the European defence industrial and technological base. A total of 2,500 men and women (including around 800 from Naval Group subcontractors) are contributing to the design and production of the Barracuda submarines.

All Naval Group sites are currently mobilised for the next five Barracuda submarines. The second of the Barracuda series, the Duguay-Trouin, whose sections will be fully joined by the end of this year, will be delivered in 2022. The third, the Tourville, is being integrated at the side of the Duguay-Trouin. At the Naval Group site in Nantes-Indret, the assembly of the propulsion system and of the nuclear boiler module of the fourth, the De Grasse, is also underway. Finally, Naval Group teams have begun forming the first elements of the hulls of the fifth and sixth submarines, the Rubis and the Casabianca, as well as elements of their nuclear boiler modules.

The infrastructures at the Toulon naval base have been modernised to accommodate this new generation of submarines: «We are ready and very proud to work on the through-life support of the Suffren (S635) in Toulon», said Vincent Vimont, Director of the SSN Operational Maintenance Program at Naval Group.

The project started with definition studies in 2014 and mobilised around 200 people from Naval Group and from 15 subcontractors. Two other basins will also be modernised in the coming years. The teams at the Naval Group Toulon site, specialised in the through-life support of submarines, have been trained in the new technical specifications of the submarine and in the use of the new facilities. They are now qualified to carry out maintenance operations on the Suffren (S635) and her sisterships.

«We managed to optimise the sea trials phase within a 6-month schedule, including 100 days at sea! By comparison, for the Rubis-class it was 15 months! This is the first time that a new vessel has been able to sail twice in a continuous one-month period during her sea trials phase. This demonstrated the submarine’s endurance to our client. To improve our work efficiency, we reduced the number of ashore trials and optimised sea trials», says Philippe Nezondet, head of Suffren (S635) trials at Naval Group.

The sea trials – conducted by the DGA as the ship is manned by the French Navy – aim at proofing the Suffren capacities and the conformity to the ship specifications in order to qualify the Barracuda submarines. These sea trials represent an intense validation phase for a nuclear submarine’s on-board installations. The operations conducted progressively over several test campaigns have made it possible to ensure that the vessel is watertight underwater, that she can be properly maneuvered, but also to assess the performance of the combat system, tactical weapons and all the high-tech equipment on-board. These tests were concluded with the firing of the SM39 missile on September 23, and of the Naval Cruise Missile (NCM) on October 20. The NCM is a major advantage of the Barracuda submarines over their predecessors: French submarines will now be able to fire underwater and hit a land-based target several hundred kilometres away. This new capability guarantees the technological superiority of French Navy ships.

Concept Ship

The SMX31E is Naval Group newest submarine concept. She integrates the latest digital technologies for reinforced operational efficiency and significant versatility of use. Stealthier thanks to her biomimetic covering, the ship also benefits from an unmatched electrical energy storage capacity and a new propulsion concept.

SMX31E
Naval Group says its SMX31E concept study is stealthier, more autonomous and flexible than current designs; its improved stealth is the result of the biomimetic shape and the skin material which absorb active sonar emissions (NG image)

Naval Group seeks to build a long-term vision, consistent with the operational needs expressed by its customers in order to invest in systems which will remain technologically superior over the 30 to 40 years of ships’ lifecycles.

Naval Group naval architects project themselves in the future. On the horizon of 2040, in a context of permanent surveillance of oceans, navies will have to navigate in very intricate environment. The objectives for submariners will be to operate freely, to share information safely and to be able to act firmly and swiftly.

The SMX31E offers a stealthier, more autonomous and flexible solution. More than a smart ship, the SMX31E constitutes a smart naval force to gain superiority in future underwater battlefields.

The increased invulnerability is the result of the biomimetic shape and the skin material making it stealthier against active sonar emissions. Endurance is the other asset of the SMX31E – it allows the crew to be submerged for months thanks to the high energy capacities and efficient energy management system.

Using advanced artificial intelligence technology, this submarine offers maximal connectivity to interact with the rest of the fleet in a distributed underwater network. This new IT design enables the crew to collect and process data efficiently with remote sensors allowing them to master underwater tactical situation. At the end of the day, the SMX 31E can monitor areas 10 times larger than today with the same efficiency.

This smart ship always keeps human decision in the loop and becomes a force multiplier thanks to the integration of all kinds of drones including large sized drones. Connected to each other, these vectors contribute to better control an extended underwater battlefield.

First Launch of MdCN

On October 20, 2020, the Suffren, the first of the six nuclear attack submarines (ANS) of the Barracuda program, successfully completed a Naval Cruise Missile (MdCN) test firing off the DGA Essais de Missiles site at Biscarrosse (Landes).

Florence Parly salutes this success: «For the first time, a French submarine has fired a cruise missile. This success gives our Navy a new strategic capability and places it among the best in the world. This new weapon is a real breakthrough, the fruit of years of effort and investment, notably permitted by the 2019-2025 military programming law. I congratulate all those – French Navy, DGA, industry – who made this firing possible. French submarine forces could hitherto strike submarines and surface ships. They can now destroy heavy land infrastructure at long ranges».

This firing enabled the qualification of the integration of all the armaments of the Suffren, carried out as part of the ship’s sea trials conducted by the Directorate General of Armaments (DGA) since last April.

This success marks an important stage in the tests of the Suffren with a view to its overall qualification by the DGA. Her delivery to the French Navy will take place by the end of 2020, before her admission to active service in 2021.

Prepared by teams from the DGA, the French Navy and the manufacturers MBDA and Naval Group, this test firing of the MdCN naval cruise missile is the latest milestone in a series of tests which has made it possible to verify the correct operation of the weapons and, more generally, of the combat system of the Suffren.

With a range of several hundred kilometers, the MdCN can attack and destroy infrastructure targets having a high strategic value. After the Multi-Mission Frigates (FREMM), the Suffren nuclear attack submarines are the first French submarines equipped with this conventional deep strike capability.

The ability to fire the MoNC from a submarine poses a constant and undetected threat of a strike from the sea against inland targets. It very significantly increases the penetration capability of French weapons in theaters of operations.

During her trials in the Mediterranean, Suffren also successfully carried out, off the DGA Missile Tests site based on the Île du Levant (Var), a test firing of an Exocet SM39-type anti-ship missile. She also carried out several test firings of the F21 heavy torpedo. This new-generation weapon is ultimately intended for all French Navy submarines.

The qualification of the entire Suffren weapons system paves the way for the end of sea trials and its overall qualification. This will allow her delivery to the French Navy for the verification of her military characteristics and then her admission to active service.

Replenishment Vessel

The first steel plate of the hull of the first of the four new Bâtiments Ravitailleurs de Force (BRF) – replenishment vessels – of the French Navy has been cut on May 18, 2020 during a ceremony held in the machining workshop of Chantiers de l’Atlantique, in presence of Florence Parly, Minister of the Armed Forces, and Admiral Prazuck, Chief of French Navy. This ceremony marked symbolically the start of the construction of the first vessel of the Flotte logistique (FLOTLOG) program.

The construction of the first new replenishment vessel for the French Navy starts at Chantiers de l’Atlantique shipyard, in cooperation with Naval Group

The order for the construction of the four ships was notified in January 2019 to the temporary association of companies formed by Chantiers de l’Atlantique and Naval Group. Deliveries are scheduled from end 2022 to 2029. This order for the French Navy is part of a Franco-Italian program led by Organisation Conjointe de Coopération en matière d’ARmement (OCCAR), on behalf of Direction Générale de l’Armement (DGA), the French Defence Procurement Agency, and its Italian counterpart Naval Armaments Directorate (NAVARM).

The BRF with a capacity of 13,000 m3 have a mission of logistical support of the combat vessels of the French Navy. They carry fuel, ammunition, spare parts, as well as food for the vessels.

Compliant with international standards, their characteristics are adapted to their specific missions of support to the aviation group constituted around the aircraft carrier Charles de Gaulle, flagship of the naval air force group.

Chantiers de l’Atlantique carries out the global design and the construction of the four ships, and ensures the integration and the implementation of the embedded systems.

«We are at the very start of a new industrial story, which will feature once again our know how in design, building and integration of cutting edge technologies», states Laurent Castaing, General Manager, Chantiers de l’Atlantique. «This is also an excellent opportunity to demonstrate our complementarity of our businesses with those of our partner Naval Group».

Naval Group is responsible for the design, development and integration of the military systems of the platform. The combat system of the four ships, whose architecture is based on the Polaris Combat Management System of Naval Group, ensures the protection against close threats and the fight against asymmetric threats.

«Naval Group is proud to stand once again by Chantiers de l’Atlantique in the frame of this European program. This cooperation brings together the best civilian and naval expertise and will benefit our customers both on economic and operational aspects», highlights Pierre-Eric Pommelet, Naval Group CEO.

Barracuda

According to Defense-aerospace.com, Florence Parly, Minister of the Armed Forces, welcomes the first dive in the Suffren at sea, carried out on Tuesday April 28, 2020, after her departure from the naval base of Cherbourg. The Suffren is the first of six Barracuda nuclear attack submarines.

Suffren, the first of six Barracuda-class nuclear-powered attack submarines being built for the French Navy, has kicked off her sea trials with her first dive at sea. These trials were originally due to begin in early 2020 (FR MoD photo)

Led by the French Armaments Directorate (DGA), these sea trials, which will last several months, will confirm the robustness and efficiency of the submarine before her hand-over to the French Navy.

At dockside as at sea, the test campaign will follow the specific health prevention and precautionary measures linked to the COVID-19 pandemic.

The SSNs are real instruments of power, enduring and discreet. Their missions are varied, and range from support to the deterrent force, protection of the carrier strike group, intelligence gathering, and anti-submarine and anti-ship warfare. Suffren-type SSNs will add a land-attack cruise missile capability and will be optimized for the deployment of special forces.

With the Suffren, France is starting to renew its fleet of SSNs, which entered service in the 1980s, and will thus have modern submarines among the most efficient in the world.

With this first outing at sea, the Barracuda program crosses a major milestone after the launch of Suffren, on July 12, 2019, by the President of the Republic.

Over the past eight months, the program’s industrial and state teams have successfully conducted all of the Suffren’s dockside tests aimed at verifying the proper functioning of its various systems and equipment. Three prerequisites have been validated: the combat system has reached the end of its tests on land and is ready for the continuation of assessments at sea; the nuclear reactor was started at the end of 2019 after loading its fuel and, finally, in January 2020 the submarine was floated to validate the first waterproofness tests.

Started in the English Channel, these sea trials will later take the Suffren to the Atlantic and finally to the Mediterranean. Under the supervision of engineers and technicians from the DGA, the French Atomic Energy and Alternative Energies Commission (CEA), Naval Group and TechnicAtome, they will be carried out by submariners of the French Navy who will gradually check all of the boat’s technical and operational capabilities.

They are due to last several months until her delivery scheduled for later this year. During the entire phase of sea trials, the boat remains the property of Naval Group. She is placed under the responsibility of the French Navy for operational command and as a delegated nuclear operator. As the contracting authority for the Barracuda program, the DGA is responsible for testing up to the acceptance of the boat and her delivery to the French Navy.

The DGA worked with the CEA, the French Navy and industrial prime contractors to allow the program to continue under specific health conditions. Since March 16, the business continuity plan for the Cherbourg site and the Barracuda program takes into account all measures to ensure the health and safety of personnel.

In particular, all personnel on board for sea trials have been placed in preventive quarantine, and have been tested negative for COVID-19. On board, wearing a mask will be mandatory at all times and the rules of hygiene and disinfection will be strictly applied.
