The Aréthuse class were submarines built for the French Navy (French: Marine Nationale) in the 1950s. They were designed as attack submarines for anti-submarine warfare and were referred to as Sous-marins de Chasse by the French Navy. These submarines had advanced sensors and were very quiet. They were influenced by the World War II German Type XXIII U-boats. The Daphné class are an enlarged version built for the French, Pakistani, Portuguese, Spanish and South African navies.
