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.
