Excellence in every aspect
of submarine operations for more
than a hundred years
DCNS’ experience in submarine warfare dates back to the
very beginning of underwater exploration, when the world’s
first torpedo-carrying submarine was built in 1887 at the
Mourillon arsenal in Toulon (later to become a DCNS
industrial site). Since then, the Group has developed
generation after generation of cutting-edge programmes,
accumulating expertise and continually improving its
industrial plants and techniques as it carried out the most
innovative projects and highly complex integration programmes.
The most extensive expertise available
Over the years, DCNS has developed the capacity to design
and build all three major categories of submarines: dieselelectric submarines, nuclear-powered attack submarines and
nuclear missile-launching submarines – ranging in size from
the smallest, used for coastal defence, to the largest, used
by France’s Strategic Oceanic Forces. Being the one and
only industrial group in the world to conceive and build
both diesel-electric and nuclear submarines gives DCNS its
unique expertise and strength. DCNS continues to develop
submarines as well as their equipment and systems. Each new
programme leads to technological improvements which can
then in turn be used on board other classes of ships, either
diesel-electric or nuclear. This guarantees innovation and
maintains industrial competences and assets.
From design to dismantling:
answering all Navies’ needs
DCNS’ services cover the entire life-cycles of submarine
fleets from early planning to dismantling. We design,
build and maintain ships, fit them with equipment,
develop and integrate systems. We also provide training
services. Also, the Group’s engineering department
and powerful industrial plants can be employed to work
on any type of programme. This covers designing a new
ship or adapting an existing type of ship to any needs.
DCNS integrates the very best weapons, combat systems
and other equipment into submarines under construction
or already in service.
RESPONDING TO NAVIES’ NEEDS
The experience in designing, building and maintaining
submarines, systems and equipment for over a century
has shaped a complete range of ships to respond to
Navies’ every needs.

ENSURING SUBMARINE FORCES
MEET THEIR FULL POTENTIAL
Every Navy has specific requirements, depending on its environment and the age
of its submarine force. This is why DCNS guarantees the complete operational
command of a consistent fleet rather than simply build ships from its catalogue.
TAILOR-MADE SOLUTIONS BASED
ON TRIED-AND-TESTED PLATFORMS
DCNS’ all-encompassing approach of
submarines gives Navies a dual guarantee.
Firstly, all our solutions have very high
standards of performance and reliability,
thanks mainly to the privileged partnership
between DCNS and the French Navy.
The four SSBNs and six SSNs currently
operated by the French Navy have all been
built and are currently supported by DCNS.
All our solutions are based on tried-and-tested
processes and technologies. Secondly,
DCNS’ offer is modular, enabling us to adapt
to client Navies’ needs. From the outset,
DCNS submarines and services are designed
as platforms with an adaptable architecture.
This means DCNS can develop a customized
solution to meet the specific requirements
of every client Navy.
From design to dismantling and from
naval base infrastructure to Through-Life
Support (TLS), DCNS offers control on every
aspect of a submarine’s life-cycle.
This means the Group can support Navies
in the long term, whether they are
acquiring their first ever submarine force,
strengthening or modernising an existing
fleet, or developing and consolidating
their industrial capacity in this area.
PROMOTING THE INDEPENDENCE
OF CLIENT NAVIES
A Navy’s capacity to operate its submarine
fleet independently and sustainably has
considerable strategic importance, especially
because of its use of significant resources
and cutting-edge technologies. This is why
DCNS’ submarine solutions are based on
transfers of know-how and technology.
Working closely with client Navies and specially
selected local industrial partners, the Group
has developed tried-and-tested programmes
to upgrade naval skills in every field from
design construction and Through-Life Support
to crew education and training.
HIGHLY SKILLED DCNS EMPLOYEES
TAKE PART IN SUBMARINE ENGINEERING.
A long-term partnership with
DCNS set up a special submarine design school for Brazilian engineers in 2011 at its Lorient
site. After a period of eighteen months of training, DCNS has continued carrying out its design
support at the Brazilian site of Sao Paulo. The objective performed in Brazil consists in helping
to build the non-nuclear part of the first nuclear attack submarine to be designed in Brazil. The
submarine is still to be commissioned in 2025.
Le Terrible is the latest of
Le Triomphant-class SSBNs
to have entered active service,

the new generation M51 ballistic
missile. The four-unit series
of Le Triomphant-class
submarines is the major
component of French deterrence.
DCNS is responsible for its
through-life support, having
signed a contract that guarantees
a permanent presence at sea for
the French Navy’s strategic force.
Barracuda-class SSNs bear the very
latest know-how and technologies.

DCNS is the French Navy’s historical industrial partner. DCNS can boast over
50 years’ experience in the field of nuclear-powered submarines, alongside
continuous work on diesel-electric submarines for the past 100 years. The Group
has always benefited from long-term programmes enabling it to develop and
maintain a remarkable industrial base, which is a permanent source of innovation
for DCNS and its partners.
DCNS has acquired an ability to master highly
complex programmes, whether nuclearpropelled or diesel-electric submarines. The
Group’s experience in designing and building
nuclear submarines is an excellent illustration
of this ability. DCNS started research on
nuclear propulsion decades ago, before
designing and building France’s first nuclearpowered submarines in the 1960s – six units
of which Le Redoutable was the first-of-class.
When it entered service in 1971, it was an
example of technological prowess: one whole
programme had encompassed the design and
construction of an 8,000-ton nuclear-powered
ship that could fire a strategic missile whilst
submerged. Driving this programme proved
DCNS could mobilise and coordinate
a vast naval and military industrial base.
The construction, maintenance and continuous
upgrade of Le Redoutable-class SSBNs went
on. In the meantime, DCNS began preparing
the next generation of French SSBNs in the
early 1980s. Le Triomphant was the first
of four ships – the fourth being Le Terrible,
which was designed to be equipped with
the new M51 ballistic missile from the outset.
Maintaining an effective ocean-based
deterrence involves a constant quest for
innovation in matters such as propulsion,
hull shape, discretion, detection and
combat systems. One must bear in mind
that missile-launching nuclear-powered
submarines are the most highly complex
systems ever built by mankind.
Mastering their conception, construction
and maintenance has thus allowed the
Group to remain at the forefront of
submarine technology for decades. The
resulting innovations have been adapted
to suit all our products, of which the front
runners are the diesel-electric submarines
built for partner Navies.
SSBNS AND SSNS – SHARING THE VERY
HIGHEST LEVEL OF TECHNOLOGY
The know-how and technologies developed
for French SSBNs were used directly to help
design SSNs for the French Navy. The expertise
acquired while building Le Redoutable-class
SSBNs was therefore used to develop the first
generation of French SSNs in the early 1980s.
The six Rubis-class SSNs resulting from this
programme were the most compact nuclearpowered submarines ever built. Although
at first, these ships had a design derived from
the diesel-electric Agosta submarine, during
the so-called “Améthyste upgrade” they
were subsequently given an optimised
hydrodynamic shape. Rubis-class submarines
already have a new successor: the new
Barracuda-class. The Barracuda programme
benefited from the Le Terrible programme,
using the progress in propulsion and discretion
thus acquired and gathering the most advanced
technologies together. Scorpene® 2000 and
Scorpene® 1000 will also benefit from these
HOURS OF WORK WERE REQUIRED
TO BUILD LE TERRIBLE.
Anticipating future needs with the SMX
DCNS is constantly striving to think out of the box and invent innovative solutions to anticipate
on client Navies’ future requirements. This results in our SMX concept-ships. In 2010, DCNS
explored extreme mobility and semi-surface movement with SMX-25. In 2012, DCNS went on
to unveil SMX-26, which is designed to open access to new operating zones: coastal and shallow
waters normally unsuitable for submarines. In 2014, SMX® Ocean is an innovative and realisable
concept-ship which is a transposition of a SSN Barracuda into a SSK, integrating major innovations.
When DCNS’ Scorpene® 2000
entered service, they imposed
a new standard of performance
– therefore establishing
themselves as the preferred
choice of our partner Navies
throughout the world. The
Scorpene® 2000 are oceangoing submarines which combine
extreme mobility, a large
weapons payload (missiles,
mines and all types of heavy
torpedoes), superior acoustic
discretion and a powerful
acoustic surveillance ability
– even at top speed.
Scorpene® 2000 owes its
success to its modular design,
which means it can be adapted
to suit each Navy’s requirements,
integrate the latest technological
Scorpene® 1000’s manoeuvrability enables
it to operate easily in shallow waters.

DCNS, YOUR NAVAL PARTNER • SUBMARINE FORCES • 11
RELIABLE AND TAILOR-MADE
DCNS has a whole family of high-performance diesel-electric submarines
available: Scorpene® 2000 and Scorpene® 1000. These submarines are
both modular and adaptable to client Navies’ requirements. They cover
all types of missions and environments, from open oceans to littoral waters.
Mastering the building of SSN, it can also propose bigger submarines
to customers requiring longer missions and larger payload.
CONTROLLING LITTORAL WATERS
DCNS has maintained constant expertise
in diesel-electric submarines ever since
the end of the 19th century when the
Gymnote was designed. The Gymnote was
the first electrically propelled submarine
which was capable of launching torpedoes.
Since then, new generations and new
types of submarines have constantly been
developed and improved over time.
Submarines like Naïade, Émeraude, Saphir,
Minerve, Aurore, Daphné, Agosta, and
Scorpene® 2000 – ranging sizes from 400 to
over 3,000 tons – were designed and built
to adapt to operational constraints met
by the French Navy as well as partner Navies.
DCNS completed the development of
Scorpene® 1000 after client Navies had shown
interest in a submarine optimised for coastal
operations. DCNS wanted to design a submarine
both capable of carrying out diesel-electric
submarines’ usual missions and also operate in
shallow waters with specifically adapted systems
and equipment. Scorpene® 1000 can therefore
handle every type of threat thanks to its high
performance sensors and ability to fire heavy
weapons, whilst its small size and manoeuvrability
allow it to operate easily in shallow waters.
Its design is based on sea-proven technological
and architectural solutions and its effectiveness
is also guaranteed by its highly automated
adapted combat system which can be manned
by a small crew. This ensures client Navies
operate a reliable and trustworthy submarine,
yet at a reduced price and guaranteed lower
A TECHNOLOGICALLY ADVANCED
SEA-PROVEN POLYVALENT SYSTEM
Scorpene® 2000 is the latest ocean-going
diesel-electric submarine to have been
designed by DCNS. Scorpene® 2000 is
equipped with the very best submarine
technology available: it can travel at over 20 kts
and it offers the best indiscretion ratio on the
market. This performance can be drastically
improved by modular Submerged-autonomy
boosting sections (see below). Scorpene® 2000
can offer high performances on every mission,
be it antisubmarine warfare, intelligencegathering, or special operations. Its modular
design is compatible with a wide range of
systems and equipment, which makes it the
perfect choice for Navies looking to meet both
current and future needs with a cutting-edge

Submerged-autonomy boosting sections
All navies have different concept of operations for their submarines, and these concepts
may evolve during the life time of their ships. That’s why, to boost submerged autonomy,
DCNS offers three different solutions, each allowing specific uses. They are provided in
completely modular and independent sections. Those three solutions are:
– sea-proven MESMA®, based on steam-cycle principle, resulting from DCNS’ expertise
in nuclear submarines;
– FC2G (Fuel Cell 2nd Generation), including the reformer unit to produce hydrogen from
the ship’s fuel. They offer the best performance at patrol speed;
– lithium-ion batteries, rechargeable at sea. They are very efficient for high speeds.
The DCNS-designed SUBTICS®
submarine combat system
can be adapted to fit all types
of submarines, whether under
construction or during an
upgrade, and the capacity of
its sensors and weapons can be
optimised. SUBTICS® has been
selected by many of the world’s
Navies to equip submarines
designed both by DCNS
(Agosta, Scorpene® 2000,
Scorpene® 1000) and its
competitors (U209, A12, A17).
It also exists in a specific
version called SYCOBS for
of the French submarine forces.
The F21 can travel extremely fast and far. It can counter the very latest generation

SYSTEMS AND EQUIPMENT
ADAPTING EVERY SUBMARINE TO
ITS SPECIFIC OPERATIONAL ENVIRONMENT
A submarine’s performance depends both on its design and equipment
and on how well these elements combine. This is why DCNS does not only
integrate complex systems, but also designs and produces a large number
of essential pieces of submarine equipment.
OVERALL PROJECT ARCHITECT,
NAVAL EQUIPMENT SUPPLIER,
AND SYSTEMS INTEGRATOR
DCNS’s hundred years’ experience in project
design, includes designing and manufacturing
a range of major systems, perfectly adapted
to the constraints of integration into a military
submarine. The field of DCNS’ expertise
ranges from platform equipment (exchangers,
steering apparatus, hull sections, etc.), to
combat equipment (masts, tubes, torpedoes,
countermeasures, etc.) and power-propulsion
systems (drive-trains, AIP, etc.). The Group’s
expertise in manufacturing naval equipment
guarantees its client Navies performance
and innovation. Furthermore, the permanence
of the Group’s industrial base promises
long-term availability. DCNS also has
outstanding integration skills, and is able
to integrate specific equipment chosen by its
clients, as shown for instance by the total
integration of SUT torpedoes into the SUBTICS®
system on the Chilean and Indian Scorpene®.
Knowing what equipment is required for
what mission or understanding how to
maintain satisfactory overall performance
are amongst the questions we provide
answers for to our client Navies.
Turnkey solutions are simply not always
the appropriate solution. This is why DCNS
supplies client Navies with systems that
guarantee ships to achieve their ambitious
performance objectives, whether the ships
are DCNS-designed or not and whether
the ship is being built or upgraded.
EXPERTISE THAT REACHES
BEYOND OUR SOLE PRODUCTS
DCNS’ expertise is not limited to its sole ships,
systems and equipment – it covers the whole
field of submarine building and technology.
The Group possesses recognised experience
in adapting its combat systems to other types
of submarines, including the U209, A12 and A17.
The Group’s industrial programmes abroad
(India and Brazil) have developed specific
expertise in integrating equipment produced
locally by third-party manufacturers selected
in collaboration with client Navies.
OF THE WORLD’S SUBMARINES HAVE BEEN
FITTED WITH SUBTICS® COMBAT SYSTEMS
(10 AS PART OF UPGRADE PROGRAMMES

At the forefront of underwater warfare
DCNS has dedicated laboratories and engineering departments to Research and
Development – it has also created a new branch within the Group called “DCNS Research”.
Our Research and Development teams are busy preparing for the future of submarine
warfare and are working on technological breakthroughs and future capacities.
Amongst their many fields of exploration, DCNS has carried out pioneering research
into two key concepts for the next generations of submarines: anti-air self-defence
and launching and retrieving Unmanned Underwater Vehicles (UUV).
DCNS rules to design safe submarines are based on
a century of experience and feedbacks. Use of complex
simulations and mock-ups ensure respect of these
rules. Redundancy of vital systems, possibility of
separate mode of control in downgraded situations,
and adapted damage control equipment and
procedures ensures the survability of the ship.
It is fundamental for a submarine’s efficiency and survability. The
experience gained in designing a 14,000 tons SSBN, beyond the
stealthiest of the world, benefits to all DCNS made submarines, including
for the high speed necessary to the activities of a modern SSK.
Some equipment are too
specific and sensitive to be
acquired externally. That’s why
DCNS produces a wide range
of product, like torpedo tubes,
masts, exhaust valves,
shaftlines or countermeasures.
It includes the definition of complete specifications,
and the ability to test those equipment in DCNS
facilities. This capability is of utter importance for
the customer, who has the choice between different
suppliers, including those of his own country.
This is fundamental for strategic independence in
the long term and transfer of technology between
DCNS and the national industries.
Equipment and material qualification
DCNS operates its own facilities to test in real conditions all equipment
and materials to be installed in a submarine. This includes resistance
to pressure, corrosion, shock, weariness, temperature, vibrations.

simulators. This helps client Navies in acquiring new skills in recruitment,
qualification and monitoring of their submarine forces and personnel.
An SSK has to go to periscope depth to charge its
batteries. The indiscretion ratio is the percentage
of the duration necessary for these charges on
the duration of the whole patrol. DCNS proposes
three modular autonomy boosting sections,
that drastically improve this parameter.
These tools are used at
every stage, from design
to building, including
training and preparation
of maintenance tasks.
