Foca-class submarine

The Foca class were a group of three minelaying submarines built for the Regia Marina (Royal Italian Navy) during the 1930s.

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.

[1] For surface running, the boats were powered by two 1,440-brake-horsepower (1,074 kW) diesel engines, each driving one propeller shaft.

[2] The lead boat, Foca, was lost to unknown causes on 13 October 1940 while laying mines off Haifa.

[4] Atropo and Zoea, the second and third vessels of the class, were used after Italy's 1943 surrender by the Allies for anti-submarine training.
