Andrasta-class submarine

Andrastra is a submarine design concept announced by the French shipbuilder DCNS in 2008. A development of the Scorpène class submarine and based on the previous SMX-23 concept, it is a smaller vessel optimised for shallow water operations. DCNS advertising material for the ship concept, in a PDF document with a date-time stamp of October 19, 2008, includes information and digital illustrations that reveal the torpedo tube configuration and other details. The draught of the proposed submarine is apparent from the numbered depth markings shown on the hull in one of the illustrations. It is designed for anti-submarine and anti-surface warfare, as well as intelligence gathering and special operations.
