The Foca class were a group of three minelaying submarines built for the Regia Marina (Royal Italian Navy) during the 1930s. All three sister ships played minor roles during the Second World War. One was lost to unknown causes while trying to lay a minefield off British Palestine in 1940, but the other two survived the war to be discarded in 1947.
