Howorth
Howorth’s initial armament was that of a typical Fletcher-class destroyer arriving in the war zone in 1943–44:
    Primary: 5 x 5-inch/38 cal. in five single mounts
    Long-range anti-aircraft: 6 x 40mm Bofors in five twin mounts
    Short-range anti-aircraft: 7 x 20mm Oerlikon in single mounts
    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
Howorth
After sustaining suicide plane damage in 1945, Howorth was modified to incorporate the 1945 anti-aircraft modification: 40mm quad mounts in the waist replacing the forward torpedo tube mount and 20mm twin Oerlikons—two on each side at the waist and two on the fantail—replacing her seven 20mm single mounts:
    Primary: 5 x 5-inch/38 cal. in five single mounts
    Long-range anti-aircraft: 14 x 40mm Bofors in three twin mounts and five quadruple mounts
    Short-range anti-aircraft: 12 x 20mm Oerlikon in twin mounts
    Torpedo Tubes: 5 x 21-inch in one quintuple mounts
    ASW: 2 racks for 600-lb. charges; 6 “K”-guns for 300-lb. charges
