Nearly 100 years building submarines

Navantia has been involved in the design, construction, and life cycle of submarines for almost a hundred years, in close collaboration with the Spanish Navy. During that time, it has worked with different models, its own or in collaboration with a variety of Spanish and foreign partners, developing construction, maintenance or upgrading programmes.

Navantia’s evolution where submarines are concerned (from Class B to the current S-80, and including the Scorpene submarine for export) and its international experience with Defence export projects, has enabled Navantia to firmly establish a solid base of expertise and skill that allows the Company to offer clients from all over the world a wide range of services that include:

  • Advice for the definition of needs
  • Life cycle
  • Upgrading and implementations to increase the life cycle
  • Training
  • Simulators
  • Integration of the air-independent propulsion system (AIP)
  • Training local industry in technology transfer projects
  • Digital services

Our submarines around the world

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

Delivery: 1944-1952 Number of Vessels: 3 This submarine is a first attempt of the industry to carry out a national design and construction.

SA-41 (Foca)

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 (Tiburón)

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.
