Design was developed by Orlando in 1915 on basis of earlier destroyer Audace. From Indomito class these ships differed hardly in larger dimensions, stretched forecastle and two funnels instead of three. 18000hp machinery has ensured a speed increment to 32kts. In the remaining they were close enough to last "three-funnelers" of 3rd and 4th groups.
In the end of 1915 8 ships of Palestro class were ordered, however because of the shortage of shipbuilding steel and other strategic materials called by wartime building of four of them was suspended for uncertain time. Remaining four for the same reasons were built slowly and were commissioned only in the early twenties. As a whole Palestro class ships were appeared more successful, than "three-funnelers".
In 1938 they were re-rated as torpedo boats. Shortly before the Second World War beginning it was planned to strengthen AA armament, replacing one 102mm and both 76mm guns by 4 20mm MGs, but these plans have not been realised.
