O’Bannon, 7 July 1942, shortly after commissioning

Like other early Fletchers, O’Bannon initially carried a modified Measure 12 camouflage, but this was painted over before she left the East Coast. The result was a two-tone appearance similar to Nicholas, which was in turn painted over to an all-gray color the week before the Battle of Guadalcanal, 13 November 1942.
   After O’Bannon was modified, she appeared in dazzle camouflage (see below) during part of 1944, including the day she was presented with her Presidential Unit Citation. Later, she was repainted in overall ocean gray, which she carried through the end of the war.
