Project history: Odero design. Development of Sauro, at the expense of insignificant increasing of the hull it was possible to install more powerful machinery, that has ensured a speed increment in 1kt. Additional side fuel tanks allowed to raise fuel stowage. As well as on the previous classes, they had a significant overload (design standard displacement was 1073t). On trials all have exceeded contract speed, but at full load reached no more than 33kts.
Modernizations: 1939 - 1940, Euro, Turbine: - 2 x 1 - 40/39; + 4 x 2 - 20/65 Breda 1935, 2 DCT
1942, Turbine: - 1 x 3 - 533 TT; + 2 x 1 - 37/54 Breda 1939
Naval service: Espero was sunk by gunfire of Australian cruiser Sydney 28.6.1940 W off Crete. Zeffiro, Nembo and Ostro 20.7.1940 were sunk by British aircraft at Tobruk. Aquilone 17.9.1940 was stricken by magnetic mines laid by British aircraft at Bengasi. Borea 17.9.1940 was sunk by British aircraft at Bengasi. Euro 1.10.1943 was hard damaged by German air bombs and has sunk at coast of Leros (Aegean sea). Turbine in September, 1943 was captured by German troops, renamed TA14 and sunk by American bombers at Salamis 15.10.1944.
