 The armament varied, as did that of the other ships of the day.During 1944-1945, the 5"/38 was recognized as the best gun for the dual role of antiaircraft and naval gunfire support, and the 40 mm was seen as the best antiaircraft gun.The older 20 mm and .50 caliber guns had been recognized to be of limited value, and were being phased out, though they appeared on some of these ships.
