The ships displaced about 8,450 tons standard and used six boilers with geared turbines for 110,000 shaft horsepower.

Eight 152 mm guns, six 100 mm guns, light anti-aircraft weapons, and two triple torpedo mounts supplied substantial offensive power. The 35 mm deck, 70 mm belt, and 90 mm turrets appear too light for comfortable medium-range combat, where even destroyer- and cruiser-caliber armor-piercing fire could be dangerous.
