SMX 24 - 2008

Tonnage	3450 tons on the surfaces
Length	88.8 meters
maximum Depth	350 meters
Speed max in diving	20 knotss (actually estimate +25/30)
Autonomy in diving	30 days
Crew	22 to 31 sailors, according to mission 18 commandos maximum or 12 men frogs)
weapons	38 carried according to configuration & mission
Modules	25 different are possible (commandos, recognition, anti ship, etc)

In 2008, DCNS launched the SMX-24 submarine, the concept focused on highly modular and plug-and-play (Plug and Fight) task suite, as far as possible the task of the application of the flexibility and carrying capacity to the maximum And, for this purpose, an innovative hull structure. SMX-24's modular task suite concept originated from the SMX-21/22, but the SMX-24 does not focus on sub-boat design, such as SMX-22, but integrates various modular kits as much as possible with the hull contours. DCNS hopes to be in 2020 around the concept of SMX-24 practical.

For Navies with requirements for ocean going submarines [aka Australia], DCNS is proposing the SMX-24 - a long-range, ocean-going conventional propulsion submarine (SSK) with an excellent payload capability. SMX-24 is a concept for a submarine that would be in service about 2020. Its size and capability fall between today's biggest diesel-electric boats and the smallest nukes: the 3450-ton boat would have an all fuel-cell propulsion system, would be capable of 20 kt submerged and could stay underwater for 30 days. The core vessel would have interchangeable modules for weapons or special forces equipment. The stub wings carry tip-mounted propulsors for high speeds - allowing the central pumpjet to be sized for cruise - and fighter-like pylons for fuel tanks - above the wings on the model - and weapons.

The DCNS-designed SMX 24 next-generation submarine will include 'plug-and-fight' hardware enabling the boat to be tailored at will for each mission. DCNS has identified 25 modules suitable for 'plug-and-fight' according to needs. These include the submarine's weapons (mines, missiles, etc.), sensors and performance-enhancing add-ons (offering greater speed, manoeuvrability or endurance, as the case may be). The modules will be housed in the wings and sail and under the operations room. Different combinations of modules result in high-performance SMX 24 configurations with capabilities tailored to specific missions.

All DCNS-designed warships combine highly modular design and production. The SMX 24 offers new prospects and a new level of modularity. This concept sub exercise has enabled DCNS to identify both architectural and technological solutions meeting the future needs of client navies. Increased modularity means a lower cost of ownership because 'plug-and-fight' modules can be shared by multiple submarines and crews. Note also that the SMX 24 requires a crew of just 22.

The SMX-24 hull length was 88 meters, width 26 meters, submerged displacement of 3,450tons. The hull section is approximately rectangular. The hull front has a streamline wing structure, which can be linked to the task module. The ship's sail is similar to a shark fin - a streamline triangles. The SMX-24 hull is divided into four modular configuration sections. The first module section is the two sides of the wing-shaped structure below, such as fighter wings mounted weapons, left and right wings can be added below. With four weapons launch tubes, the top of the two can be added to the two modules, two wings can even increase the speed to increase the low-speed electric reversible propeller.

The second module section is located inside the sail, and can be selected according to the needs of different telescopic mast module. The third section is located in the sail behind the hull on both sides, each with a large groove, the missile can be set up the vertical launch or special operations forces required. The fourth module section is located on both sides of the rear of the hull, with a row of mounting points on each side, which can be attached to different volumes. The fourth module section is located on both sides of the rear part of the hull. Functional and shape of the task modules, such as weapons launchers, sensing equipment, fuel tanks and so on. In 2008, DCNS has exhibited 25 different modules with SMX-24, including weapons, sensors, special warfare, power / fuel tank modules that increase speed or endurance.
