Andrasta 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,[3] 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 19 October 2008, includes information and digital illustrations that reveal the torpedo tube configuration and other details.[4] 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.[5]

This design evolved into the Scorpène 1000.
