The ships were originally ordered at the same time as the Palestro-class destroyers, but were postponed due to steel shortages. The opportunity was taken to modify the design to incorporate experience and lengthen the ships by 4.5 metres (14 ft 9 in).
The ships were later modernized for escort duties with the twin guns being replaced by singles and the triple 450-millimetre (18 in) torpedo tubes replaced by twin 533 mm (21.0 in) torpedo tubes. Extra light anti-aircraft guns were also fitted and the 76 mm (3.0 in)/40 caliber guns removed.
