Project history

Design was developed by builder on the basis of earlier Archimede and Pietro Micca classes. Partially double-hulled. This class minelayers are remarkable that on them two essentially various systems of minelaying, horizontal and vertical, were applied at once. In two stern horizontal tubes 8 mines were stowed and 20 more were placed in vertical trunks, as on Pietro Micca. Massive CT, carrying in the aft part 102mm/43 gun, became other prominent feature of the class, theoretically capable thanks to the high position to keep fire in fresh weather.

In 1941 on Atropo and Zoea main gun was moved on a deck fwd from CT.

Modernizations

1941, Atropo, Zoea: - 1 x 1 - 100/43; + 1 x 1 - 100/47 OTO 1938

Naval service

Foca was lost in November, 1940 in East Mediterranean. Probably, she was mined near Haifa 15.10.1940. Zoea was sunk as a result of accident in summer 1942 at Taranto, but was quickly raised and re-commissioned.
