Submarine minelayers, designed on the basis of Pisani class. Single-hulled. Mines were stored in two horizontal tubes in aft hull part.
During trials it was found out, that mine tubes were arranged unsuccessfully, and in 1935 submarines were put on refit. During works hull length was moderated (at the expense of after end), external bulges were installed and fore end form was changed as on Bandiera class.
1935: stern was rebuilt and bulges were fitted (965 / 1068 t, 68.0 x 7.10 x 4.30 m).
No significant events.
