Armament
- As Built: They were the first to get five of the then new Mark 12 5"(127mm)/38cal gun installed in five Mark 21 dual-purpose single mounts. The forward two mounts (numbers 51 and 52) were partially enclosed. (see in picture) The midships mount (No 53) and the after two mounts (numbers 54 and 55) were open. Just aft of mount 53 were two trainable torpedo tube mounts with four 21" (533mm) tubes on each. On the 01 deck, aft of mount 52, there were two single .50 cal (12.7mm) machine gun (MG) mounts next to the port and starboard rails. Two more .50 cal MGs were on the main deck, midships.
- c 1943: Due to the need for greater anti-aircraft (AA) protection, the .50 cal MGs and Mount 53 were replaced by 20 mm and 40 mm AA weapons. The type and quantity varied from ship to ship depending on when and where they were refitted. Also depth charge roll-off stern racks were added.
