Project history: Repetition of Sirena class with a little increased fuel stowage.
Iride and Ambra were converted for carrying of human torpedoes in 1940 and 1942 respectively. 100mm/47 gun has been thus removed, and on deck four (Iride) or three (Ambra) cylindrical transportation containers were installed.
Modernizations: 1940, Iride: - 1 x 1 - 100/47; + 4 SLC human torpedoes.
1942, Ambra: - 1 x 1 - 100/47; + 3 SLC human torpedoes
