Casabianca is a Rubis-class nuclear attack submarine of the French Navy. Laid down in 1981, she was launched in 1984 and commissioned in 1987. She is scheduled as likely to be withdrawn from service in 2023. Among Casabianca's operational highlights are revolved around being the first French submarine to visit the naval base at Severomorsk, home of the Russian Northern Fleet, in 2003; and patrols in the Mediterranean and in the Indian Ocean as part of the fleet surrounding the aircraft carrier Charles de Gaulle, such as in 2007.
