On October 3, 2025, Spain celebrated a historic milestone in its naval industry with the launch of the submarine S-82 “Narciso Monturiol” at the Navantia shipyard in Cartagena. The event marked the entry of the second submarine of the new S-80 Plus class for the Spanish Navy.
The S-82 is part of the strategic renewal program of the Spanish fleet, which will extend over the coming decades. The S-80 Program, launched in 2004, aims to ensure full autonomy in the design, construction, and maintenance of modern submarines.

Unlike previous generations, the project is led by Navantia itself, which developed and integrated the bioethanol-powered AIP (Air-Independent Propulsion) system. This technology allows the submarines to operate submerged for weeks without the need to surface, increasing their stealth and operational range.
Armament and Capabilities
The S-80 Plus class submarines are equipped for multiple combat scenarios, capable of operating with:
- DM2A4 torpedoes;
- Harpoon anti-ship missiles;
- Naval mines;
- And, potentially, Tomahawk cruise missiles.
- Main parameters:
- Length: 81 m;
- Beam: 7.3 m;
- Submerged displacement: approx. 2,965 tons;
- Crew: 32 sailors + 8 special operations forces (SOF) operators;
- Range: up to 8,000 km;
- Propulsion: diesel-electric with AIP integration capability.

Testing and Commissioning
Before being officially incorporated into the fleet, the S-82 will undergo more than a year of rigorous trials, including:
- Port and shallow-water maneuvers;
- Deep-sea dives;
- Combat systems verification;
- A full operational campaign.
Strategic Importance
The S-80 Plus program represents one of the greatest technological advances in the Spanish naval industry and reinforces the country’s position among nations capable of independently developing submarines.
Some technologies were developed in partnership with the United States and South Korea, and the project has already been presented to international clients such as Canada and Poland.
Together with the new F-110 frigates, the S-80 class submarines consolidate Spain as a NATO maritime power, capable not only of protecting its territorial waters but also of participating in the Alliance’s global operations.
