French naval group is the largest state-owned military ship research and development and construction enterprise in France. Its predecessor was the French Bureau of Shipbuilding (DCN), which was established in 199 1. In April 2007, it was renamed French Shipbuilding Group (DCNS).

2065438+In June 2007, Herve Guiyu, CEO of DCNS, announced that DCNS had officially changed its name to French Navy Group, in order to create a more influential brand and a louder name in the global defense field. The main products developed and produced by the company are large and medium-sized surface ships such as french aircraft carrier charles de gaulle, northwest wind class amphibious assault ship, conventional submarines such as Guishushen class and Peletier Obagus class, and triumph class strategic nuclear submarines. Among them, the "squid" class conventional submarine can fight both offshore and offshore because of its high cost performance.

Therefore, it is favored by the international market and has been successfully sold to Chile, Malaysia, India and Brazil. In addition, in April of 20 16, the French naval group's "barracuda" class conventional submarine project won the bid for the future submarine project in Australia, which established the international position of the French naval group's conventional submarine design capability.

Since 2002, the French naval group has put forward the design concept of SMX series conventional submarines every two years. Up to now, the innovative concept scheme of SMX series submarines has been launched at the European Naval Defence Exhibition, leading the development direction of conventional submarines in the future. Next, this paper introduces the design concept of SMX series conventional submarines launched by French naval group at previous European naval defense exhibitions.

SMX-2 1 catamaran submarine

From the appearance, SMX-2 1 submarine is a flat catamaran submarine, which is easily reminiscent of the "Typhoon" class strategic nuclear submarine developed by the Soviet Union. Its hull is composed of two pressure-resistant shells with the same size side by side, which subverts the drop-shaped structure of traditional submarines.

In terms of weapons and equipment, SMX-2 1 submarine mainly launches light/heavy torpedoes in a conventional way. The weapon slot under the hull can accommodate 9 mines, and the two mission modules are arranged in the non-pressure area between the double pressure-resistant shells. Task modules can be replaced according to different tasks, and each task module can carry 10 different weapons.

SMX-2 1 submarine is the first type of SMX series submarine. After its debut, this type of submarine has attracted wide attention from navies and submarine design departments of various countries.

The biggest highlight of SMX-22 sub-boat is that 1 submarine can be replaced by three at any time, and the mother boat and sub-boat can perform different tasks.

In the combat mission, after the sub-boat sails to the combat area as a combat unit, the sub-boat can carry out combat activities independently from the mother boat, while the mother boat stays in the relatively safe sea area behind. 1 ~ 2 days later, the sub-boat can return to the mother boat after completing its mission, and the mother boat plays the role of an underwater aircraft carrier.

One of the key technologies in the design scheme of SMX-22 submarine is the docking and separation technology of the mother and child boats.

SMX-23 low-cost submarine is designed on the basis of the conventional submarine of "Miyu" class. Its size is reduced, the performance indexes of speed and dive depth are changed, the weapon load is adjusted, and a small conventional submarine with small size, early performance and low cost is designed, which is suitable for shallow sea activities in small and medium-sized countries.

The SMX-23 submarine is 48.8 meters long, with a surface displacement of 855 tons and a maximum speed of 8 knots. The speed is 8 knots, the surface endurance is 1850 nautical miles, the underwater speed is greater than 15 knots, the maximum dive depth is 200m, the self-sustaining power at sea is 15 days, and the crew establishment is 19.

SMX-23 submarine is a modular submarine proposed by DNC after analyzing the efficiency-cost ratio of medium-sized conventional submarines and the naval economic strength and operational requirements of small and medium-sized countries.

The biggest highlight of SMX-24 submarine is modular design, which can carry more weapons, sensors, special operations personnel and their equipment, and the engine power is stronger. This submarine is 88.8 meters long and 26 meters wide, with a surface displacement of 3,450 tons, a maximum diving depth of 350 meters, a maximum underwater speed of more than 20 knots, and a self-sustaining force of 30 days.

Its shape design is between stealth surface ships and submarines, taking into account the needs of surface and underwater navigation. Its overall appearance is obviously different from that of a traditional submarine, more like an underwater jet fighter.

SMX-24 submarine integrates a "plug and play" module, which can be modified according to the change of mission requirements.

SMX-26 shallow sea landing submarine

This type of submarine is designed to solve the problem that it is difficult for traditional submarines to carry out the task of shallow sea and offshore environment, and it can sail in the offshore shallow water area above underwater 15 meters. The submarine belongs to the category of small submarines, with a total length of 40m, a width of 15m and an underwater displacement of 1000t.

SMX-26 submarine can stay on the seabed for a long time, and continuously observe the surrounding environment when carrying weapons and equipment to the target at high speed.

SMX-"Dayang" Conventional Power Attack Submarine

This type of submarine is based on the French navy's new "Barracuda" class attack nuclear submarine, and it is superior in endurance, situation awareness and unmanned system outside the boat.

SMX-3.0 digital submarine

SMX-3.0 submarine integrates the latest digital technology of DCNS, which can greatly improve the efficiency of submarine operations. In addition, the SMX-3.0 submarine also has an excellent power system. It has the characteristics of easy control, high endurance, strong combat capability, upgradeable system and convenient maintenance.

SMX-3 1 Future Submarine

In the overall design, SMX-3 1 adopts a lot of automation technology and artificial intelligence technology, and the number of passengers is also reduced to 15. The flat hull similar to sperm whale can greatly reduce navigation resistance and noise; The hull surface is covered with a special coating similar to scales, which has excellent stealth performance.
