AIP
A second-generation fuel-cell AIP, represents a technological breakthrough compared to current-generation AIPs in terms of performance, safety, flexibility and maintenance.
This solution combines several key DCNS innovations in fuel cell technology. Hydrogen is produced from diesel fuel by hydrocarbon reforming as required, overcoming the need to store hydrogen on board the submarine.
This revolutionary technology increases submerged endurance to three weeks; a capability that confers a decisive advantage in certain theatres of operations.

Canto®
DCNS has developed the CANTO® countermeasure system. Associated with its Contralto® tactical system, which computes the most appropriate evasive manoeuvre, CANTO® is the only countermeasure system capable of protecting surface ships from both old and new generation heavyweight torpedoes.
Operational immediately after firing, the CANTO® countermeasure is effective even when the threat is classified as being at close range.
F
FREMM
FREMM multi-mission frigate is a ship capable of carrying out several types of mission: protection of a so-called high-value vessel (e.g.: an aircraft carrier), anti-ship warfare, anti-submarine or anti-aircraft warfare, surveillance of a maritime area…
These ships respond to the needs of client navies, including the French navy and two international clients, the Moroccan navy and the Egyptian Navy.

With 12 frigates, DCNS is thus the prime contractor of the largest European naval defence program.
The FREMM multi-mission frigates are equipped with the most recent technologies developed by DCNS and the best systems available on the market.
H
Hermione
The Hermione was a 12-pounder Concorde class frigate of the French Navy. She became famous when she ferried General Lafayette to the United States in 1780 for support to the Americans in the American Revolutionary War. She grounded and was wrecked in 1793.
M
MARPOL
MARPOL is an international marine environmental conventions. It was developed by the International Maritime Organization in an effort to minimize pollution of the oceans and seas. The objective of this convention is to preserve the marine environment in an attempt to completely eliminate pollution by oil and other harmful substances.
MTS (Major Technical Shutdowns) No.2
A Major Technical Shutdows NO.2 is a long period of immobilization, which will include in addition to conventional maintenance and repair work a mid-life upgrade of Charles de Gaulle.

Narval
The Narval and the world’s first operational torpedo-carrying submarines
The 1860s see the arrival of the first torpedo boats and military submarines, with the 1863 launch of Le Plongeur, the first motorised submarine, which paves the way for Le Gymnote in 1886 and Le Narval in 1899.
O
OTEC (ocean thermal energy conversion)
The principle of Ocean Thermal Energy Conversion (OTEC) is based on harnessing the difference in temperature in tropical waters between the surface water, which is at about 25°C, and water at depth, which is at 5°C at a depth of 1,000 metres. This temperature difference allows the continuous production of electricity.

SETIS®
The CMS, or Combat Management System, constitutes the IT brain of a combat vessel. It allows the analysis and integration of external data along with those gathered by vessel sensors, and the presentation of a tactical situation and proposal of actions linked to the deployment of weapon systems or countermeasures. For surface vessels, DCNS has developed a range of multi-function combat management systems, which respond to the operational needs of the 21st century. SETIS® is offered in two versions: integrated combat for corvettes or light frigates and combat superiority for frigates and destroyers. It integrates a broad range of equipment types, sensors and long-range weapons, which provide the capacity to simultaneously conduct all types of defence and attack actions. It is also equipped with an ergonomic and intuitive interface that allows the crew to be extremely reactive in the case of a significant event.
Scorpène®
The Scorpène® 1000 and 2000 are new-generation, conventional-propulsion submarines. Of an intermediate size and highly capable in terms of mobility and discretion, they are suited to a very broad range of operations.
With 14 submarines sold, the Scorpène® 2000 has now become an essential reference for conventional-propulsion attack submarines for Navies all around the world.
T
Triomphant
Le Triomphant, the first new-generation Ship Subsurface Ballistic Nuclear (SSBN) submarine, is launched in 1994 and enters active service in 1997, 8 years after the DCNS teams in Cherbourg began work on her construction. Larger, faster and much quieter than her predecessors, Le Triomphant is also 10 times better at detecting other submarines. Her hull has an anechoic coating designed to absorb sonar waves. 4 submarines of this class were built by DCNS, the last - Le Terrible - entering service in 2010.
V
Vipère®
The Vipère® multifunction buoy offers periscope performance without having to come up to periscope depth. Vipère® enhances a submarine’s intelligence-gathering capability while remaining deeply submerged and without compromising discretion. Data gathered by the sensor payload is relayed in real time to the host submarine. Depending on operational needs, the buoy’s payload can also include communications equipment, a satellite positioning system to reset inertial platforms, electronic warfare systems such as a radar warning receiver, or an electro-optical package with a TV/IR camera to visually monitor an area of interest.
