Twining’s armament was that of a typical Fletcher-class destroyer from 1943–4: five 5-inch guns in single mounts, ten 40mm guns in twin mounts and ten 21-inch torpedo tubes in quintuple mounts plus 20mm guns and depth charges. She returned to the west coast too late to received the “1945 refit.”

    Torpedo Tubes: 10 x 21-inch in two quintuple mounts
    ASW: 2 racks for 600-lb. charges; 6 “K”-guns for 300-lb. charges
Her electronics were also typical:
    Radar: SC (air search) and SG (surface search), Mk 37 (fire control)
    Sonar: QC
From the beginning, Twining also carried 20mm single mounts, eventually mounting four in the waist and three on the fantail.
