Ship project history: Increased Pisani with more powerful engines, two additional TTs and hardly higher endurance. Single-hulled. They had an insufficient stability, for its correction soon after completion submarines received external bulges which have lowered speed from 17.5/9 to 15/8kts. Then in a fore end on an extent about 5m aft from a stem the deck was lengthened for seaworthiness improvement.

In 1942 Luciano Manara (and, probably, others) has passed refit, in which course received smaller CT.

Modernizations: 1930 - 1931, all: bulges were fitted, max speed was 15 / 8 kts.

1942, Ciro Menotti: - 1 x 1 - 102/35; + 1 x 1 - 100/47 OTO 1938

Naval service: Santore Santarosa grounded near Tripoli 20/1/1943, torpedoed by British MTB260 and later scuttled.
