The Agosta-class submarine is a class of diesel-electric attack submarine developed and constructed by the French DCNS in the 1970s to succeed the Daphné-class submarines. The submarines have served in the French Navy as well as exported to the navies of Spain and Pakistan. It also used by Royal Malaysian Navy for the training purpose. They were replaced in French service by the Rubis-class nuclear attack submarines but are still in active service with the navies of Spain and Pakistan. The French Navy grouped this model of submarine in their most capable class as an océanique, meaning "ocean-going."
