The Agosta-class submarine is actually two related class of the fast-attack submarine developed and constructed by the French DCNS to succeed the Daphné submarines.

The first class, Agosta–70s is a diesel-electric submarines that were developed and constructed in 1970s, and served in the French Navy as well as exported to the navies of Spain, Pakistan, and Malaysia. The Agosta-70s are in the active service with the navies of Spain and Pakistan, and formerly by the French Navy when they commissioned the Scorpène class submarines.

The second class, Agosta-90B, is an air-independent propulsion submarine that was eventually designed by the DCNS in 1990, but eventually sold the propriety designs, technology, equipment, to Pakistan in 1992. In a joint venture with KSEW and the DCNS, the Agosta 90Bs features the air-independent marine propulsion. The Agosta-90B are slightly larger and modified submarine that has a crew of 36 plus 5 officers and can be equipped with the MESMA air-independent propulsion (AIP) system.
