The S-80 class, one of the most advanced NATO conventional submarines, is capable of carrying out a wide range of missions, including anti-surface warfare, anti-submarine warfare, intelligence gathering and surveillance among others. They were also designed to incorporate land attack capability in the future.


Isaac Peral is the first of four S-80 class submarines. With this program, Spain becomes one of the few countries that can design and build submarines, extremely complex vessels that must operate autonomously for long periods of time in a hostile environment.

“The success of this program lies mainly in two key factors: the skills of the women and men that have designed and are building these submarines, and the collaboration approach that we have adopted as a working method and that will continue throughout the entire life cycle of the submarines. Trust and cooperation with our customer and with the user of our product are undoubtedly key for Navantia,” Navantia’s Chairman, Ricardo Domínguez, commented.

“We are taking a giant step forward in this programme and today we feel particularly proud of our Navy, heir to the great seafarers of history who transformed the world,” said the Minister of Defence, Margarita Robles.

The S-80 submarines have an overall length of 80.8 meters, a diameter of 7.3 meters, and a submerged displacement of around 3,000 tonnes. They include the integrated combat system and platform control system developed by Navantia Sistemas.
