Armament

The Argonauta-class submarine was the first sub-class of the 600 Series of coastal submarines built for the Regia Marina (Royal Italian Navy) during the 1930s. Some of these boats played a minor role in the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists. Of the seven boats built in this class, only a single one survived the Second World War.
