Ship project history: These boats, designed by Eng Attilio Bisio (of SVAN Yards) and the Navy, were 'naval tanks', provided with two lateral caterpillar chains for overcoming harbour barrages. They were designed to force the main Austrian naval base of Pola.

Modernizations: None.

Naval service: Cavalletta was scuttled on 13 April 1918 off Pola, together with Pulce, Grillo damaged by Austrian gun fire, was scuttled on night of 14 May 1918 while forcing the barrages of Pola. She was raised by the Austrian Navy, which tried to copy her.
