Navantia has begun the improvement and development of the S-83 submarine , after installing the advanced Air Independent Propulsion ( AIP ) system in one of its shipyards in Cartagena, Spain. This technological equipment makes the S80 class one of the most sophisticated submarine models in the world.
Installation of the AIP system and other technologies
The AIP system allows the submarine to generate hydrogen on board, using a process that uses bioethanol , an alcohol produced in an efficient and environmentally friendly manner. This hydrogen, together with oxygen stored on the submarine, is used to produce electricity, by means of a fuel cell, which recharges the S-83’s batteries and allows it to remain submerged up to two to three times longer. This adjustment promotes the sustainability and performance of submarines.
One of the exceptional aspects of this technology is the ability to operate at any depth and in multiple operational conditions, giving the S-83 unparalleled flexibility in naval missions. This positions Navantia ‘s AIP system as the most advanced in its category.
The S80 class submarines are the only ones in the world in the 3,000 ton range to possess this innovative AIP technology. In addition, their design has been optimized to achieve a minimal acoustic signature, making the submarine virtually undetectable. A very interesting and valuable technological advancement.
This feature, together with the efficiency of its propulsion system, improves the operational capacity of the S-83 and allows for new export opportunities, consolidating Navantia’s international position and benefiting its network of collaborators.
