Press Release, , October 2023: The S-81 submarine Isaac Peral has successfully overcome the last safety milestone with navigation at the maximum operational depth, before its commissioning to the [Spanish] Navy. With the participation of Navantia, the Navy and the Ministry of Defence, this test took place last Tuesday. Therefore, the submarine has completed a major milestone and it will continue to undergo various tests until its final delivery.

The S-80 submarine construction programme thus consolidates itself as a strongly powerful product in the international market and also positions Navantia as a spearhead in the military submarine navigation.

The programme for the construction of four S-80 submarines for the Navy is a huge technological leap for Navantia, the Navy and the Spanish industry. With the execution of this ambitious programme, Navantia becomes a Technical Design Authority and as such it participates in the new Technical Office (OTACV), which will implement a new support methodology.

The president of Navantia, Ricardo Domínguez, has expressed his gratitude to the participants in this programme: “Sailing at maximum operational depth is a symbolic moment for all those who are involved: the Ministry of Defence, the Navy, Navantia personnel and the collaborating industry. It is, therefore, an excellent moment to recognise everyone’s work because, with the S-81, not only Navantia makes a qualitative leap forward, but Spain makes also a qualitative leap forward in its defence capabilities and in its industrial and technological base”.
