S80, a new generation of submersibles

S80, a highly technical submersible

Navantia has in the new submarine Class S80, being manufactured for the Spanish Navy in the Cartagena Shipyard, one of the most avant-garde products in its catalog. It is a new generation submarine, technologically very advanced, which represents a qualitative leap with respect to conventional submarines.

It incorporates the most advanced technology, such as the propulsion system independent of the atmosphere (AIP) and integrates a state-of-the-art system for combat and support for the operations of special forces. This high degree of technification also implies a reduction in the number of people that man it: the crew is reduced to 32 sailors.

It will be able to carry out both support operations integrated in the Force, for which it will have a system of communication and exchange of information in real time that is 100% reliable and safe, as well as other missions of surveillance, deterrence and confrontation of threats such as minefields, ships of surface and other submarines, both conventional and nuclear.

First submarine of Spanish design

The S80 program is the first submarine with a completely Spanish design, since until now the submarines that have been built had a French or North American design. This submersible is the first one with 100% Navantia design, and therefore it is a step forward in the sovereignty of the National Defense and in the capacities of our naval industry. Only the most advanced countries in the world are capable of developing a technological project of this magnitude, which is why Spain ranks among the best in the sector.

If for Navantia the execution of this ambitious program of submarine construction is a very demanding challenge, for the Spanish industry it is not less; It has a great participation in this project, which will involve a technological development of great magnitude through industrial cooperation programs, as well as the possibility of exporting a product with a very high degree of technology.

Result of a long experience

The first submarine of the S80 class to be afloat will be number 32 of all those that have been built in the Cartagena Shipyard. The first of these was the B1, which was launched in 1921, while the last, so far, has been the Tun Razak, a submarine of the Scorpene type, whose launching took place in 2008.

sail around the world

Navantia has been immersed, for more than 90 years, in a process of evolution and improvement of the design, production and life cycle of submarines. During this period, different kinds of submersibles have been built in their shipyards, integrating the most complex systems with the collaboration of national and international partners.

Class B

Delivery: 1921-1926 Number of Vessels: 6 They were the first to be built at the Cartagena Shipyard, based on the Holand submarines of the Electric Boat Company of the United States.

Class C

Delivery: 1927-1929 Number of Vessels: 6 They were also based on the North American Holland design, although with slight variations.

Class D

Entrega: 1944-1952 Número de Buques: 3 Este submarino es un primer intento de la industria para realizar un diseño y construcción nacional.

SA-41 (Seal)

Delivery: 1963-1964 Number of Vessels: 2 Based on a German design, they were considered assault submarines and were less than 14 meters in length. The problems that they generated and their poor military value, it was advisable to remove them from service in 1969.

SA-51 (Shark)

Delivery: 1964-1965 Number of Vessels: 2 Based on the design of the German Type Hai, they were a little larger than "Seal" kind (18.8 meters in length) and capable of carrying two torpedoes.

S-60 (Daphne)

Delivery: 1973-1975 Number of Vessels: 4 Constructed with French design, with a characteristic bow bulb they receive the names of marine animals: Dolphin, Tonina, Marsopa and Narval. These are already almost sixty meters long and have a crew of 56 people.

S-70 (Agosta)

Delivery: 1973-1975 Number of Vessels: 4 Also with French design (Galerna, Siroco, Mistral and Tramontana), three remain active, since only the Siroco has been decommissioned, in June of the year 2012.


Delivery: 2005-Present Number of Vessels: 10 Born as a Hispano-French project to supply two ships to Chile, manufactured between France (bow) and Spain (stern). The same collaboration formula was used for the delivery of two other submarines to Malaysia. Currently 6 more submarines are being built for India, in this case in the MDL shipyards in Bombay.
