DCNS bets on the all-electric ship

Historically, naval forces have always been at the cutting edge of technology. On an ongoing basis, military personnel and manufacturers are seeking to integrate innovations that will increase the efficiency and capabilities of their buildings. To this end, all the major industrial groups are considering the ships of tomorrow. Concept ships are being studied with supplier networks in order to identify future products and plan research and development (R&D) efforts for the coming years. In the area of ​​surface units, DCNS, the European leader in the sector, worked on a futuristic platform resulting from the needs expressed by the navies to replace their frigates in about fifteen years. “This translates into a significant increase in operational capacities, particularly in terms of detection and action. The combat vessels will act alone or in a network in coastal areas. They must be able to fully understand their environment, deal with conventional or asymmetric threats, act in a graduated manner with weapons of varying lethality, ”explains Gilles Langlois, at DCNS.

To meet needs, the French group is moving towards all-electric vessels. Not only in terms of propulsion, but also in terms of weapons. Its concept, Advansea, relates to a ship of 120 meters and more than 4000 tonnes capable of reaching 28 knots. But, the great innovation is that it also displays an electrical power of 20 MW, significantly more than today's ships. For variable lethality, a laser may be used, with a variation in the intensity of the beam. DCNS also plans to carry electric cannons, whose energy charges will propel shells and, by replacing the powder, increase the capacity of ammunition bunkers. The use of these weapons, which require a high impulse energy, poses important architectural problems. To achieve a building like Advansea, 3 technological breakthroughs are necessary. First, the use of superconductivity for propulsion engines. Thanks to new materials, the objective is to limit as much as possible the energy losses in the conductive wires to improve the efficiency of the motors and reduce their size. Thus, a power and space gain is obtained, with a space requirement reduced by 50%. The second necessary technological breakthrough concerns the storage of energy for engines and weapons, which will need to recharge very quickly to display a rate equivalent to or higher than current guns. The use of new generation batteries, under study, is planned.
Finally, this ship of the future will require a real-time control system for the flow of energy to propulsion and the weapons system. DCNS estimates that these technologies will be mature within 15 years and that the adoption of the all-electric building will also make it possible to respond to the need to reduce greenhouse gas emissions and reduce the oil bill, the latter point culminating lower cost of ownership of boats.

In addition to the electrical aspect, to meet future missions, Advansea is equipped with a multifunction flat-face radar, integrating detection, electronic warfare and communication means. The building is also part of the logic of remote sensors, with the use of drones. The building is also characterized by a second platform on the roof of the helicopter hangar. Equipped with an elevator, it must be used for UAV rotations. Aft, a ramp is provided for launching fast boats or surface drones. The missiles will be fully integrated into the hull and superstructures to increase stealth.

They don't say how they're going to produce that electricity. On some boats dedicated to demining, it is an electric propulsion powered by generators coupled to gas turbines. It's better for "acoustic" stealth quieter what : Mrgreen:

If the soldiers now take care of limiting pollution and limiting costs ...... they only remain ..... what they disappear : Mrgreen:
